Recently youtube recommended this video, maybe google knows i am looking at computer things



does this thing work? if anyone is using what is your experience?



https://www.lazada.com.my/products/for-hone...9766156590.html?

https://www.lazada.com.my/products/for-hone....76275cacfRjFCV

found 2 lazmall, which should be the real thing? can't find any local seller though, not sure if there is any official distributor in malaysia.


would be nice to replace the traditional paste i guess?

some reference for you, seems like a good replacement to paste like even Grizzly Kryonaut

https://forum.lowyat.net/topic/5248294

thanks, seems like a good pad, i could order some to test it out

Don't forget to share the result here

Better to just use something actually designed for computer usage and its also reusable
https://www.thermal-grizzly.com/en/products/625-kryosheet-en

I have applied the PTM 7950 to several GPUs and laptop CPUs this past year. Compared to the other thermal paste that I have which is the CM Mastergel Pro V2, the PTM 7950 usually have around 4c better results. Application is fiddly though as there's 2 layers of plastic you need to remove on the material using tweezers or something similar.

I haven't used this on desktop CPUs though, they are expensive and desktop CPUs have much larger surface area.

EDIT :

Aside from the drop in temperatures, I also noticed the boost clocks are a bit higher as well especially on my laptop. YMMV depending on your specific designs.

4 c decrease is actually quite good i supposed, does it last long or need more frequent reapply?
Did you buy the big size and cut your self?
Need to cut exact size or bigger a bit than the surface to paste?
Does it melt away and drip to side?
Pls don't mind my question banyak2 😅

I use this, purchased from specifically this seller (but via taobao)
https://www.lazada.com.my/products/honeywel...2810954266.html
I trust this seller as they seem to be the one shown in the video with better performance

It is good, only thing that keeps my CPU/GPU from thermal throttling
It is the best choice for gaming laptops other than Liquid Metal
for desktops, can use other pastes

as for babylon52281
Honewell is better in terms of performance
but it sadly not reusable
but no need anyways since you will never need to replace it
and it is designed for computer use, Lenovo uses it in their Legion laptops
Nvidia also uses them in their own GPUs (different model but still honeywell ptm)

Some tips:
Throw it into a fridge before you apply it, makes it easier to peel off the plastic film

So Im curious if its the best thing since sliced bread, why is it not the best for desktop use?

You can use it on a desktop but it's more expensive since you need a big slice of it

Plus the Honeywell is better for direct die compared to with an IHS

So the benefits are reduced for desktops
So you could just consider using normal pastes

- It's supposed to last for many years, and I have not noticed significant reductions in performance since application
- For the size, I bought the bigger one and then cut it to size
- Cut it as close as you can to the mounting surface size
- It doesn't drip to the side like more viscous thermal paste. When removed and not hot to the touch it looks like old hard thermal paste but that's just it's phase change nature.

In terms of viscosity when cold [more viscous to less viscous]
Thermal Grizzly Kryonaut > CM Mastergel Pro V2 > PTM 7950 > Normal squishy thermal pad

Still prefer traditional high performance paste than pad.

Anyone know whether this is better than thermal grizzly paste ?

For Lenovo X1 Carbon 7G.

the problem with thermal grizzly kryonaut is the pump out that happens once it goes over 80c, so on a hot machine it will only last a few months or a year
the ptm wont pump out, at all, so it'll last for years

I'll say go for PTM, even the newer Thinkpads come with it, like P14s G4 has it

in the case of thermal paste, since TG Kryonaut is now almost a household name...I will actually recommend a sleeper which is better than Kryonaut, doesn't pump out at high temp like Kryonaut does, and outperforms Kingpin KPX as well - Corsair XTM70

not many ppl know about XTM70, most likely due to Corsair's old XTM50 being a disaster...but XTM70 is miles ahead of XTM50

I'm currently using XTM70 and have pleasant experience

how about the extreme version ? Does it still pump out?

The PTM is so hard to DIY and no shops out there sells it

Bro, I know its an old post, but could you please share the link to the ptm7950 you purchased from Taobao. Really appreciate it, thanks.

it is from this seller

https://shop272403322.taobao.com

Ty chief

You could also try Shopee (I got mine from this seller)
Costs more than Taobao but easier to use and pay with (especially if you have coins to burn).
Shipping was also quite fast for me.

Performance-wise I think cleaning out laptop fans now and then make a big difference also.

Just to be clear the 7950 pad is not the same as the normal thermal pads for ram chips or mosfets on video cards which are thicker about 2mm. These thicker pads are reusable if you're really careful, the 7950 is not.

Generally pastes give better performance compared to pads.
But there is a very good use case for pads - bare die GPU chips and laptops/notebooks cpu/gpu because the temps on these get too high for pastes and causes excessive pump out. And the high power density of current cpus/gpus is another contributor to pump out. So instead of all the headaches of re-pasting laptop cpu/gpu, slap on a pad like 7950 and you might never need to replace it in future. You can also use 7950 on desktop cpus if you're having problems with pump out but I prefer to get a bigger/better heatsink or dial down power/voltage limits on current intel cpus.

Maxtor xtp-001 might be an acceptable alternative, I'm looking for 7950 myself.

Many people don't know that TG kyronaut is not meant to normal PCs. Its meant for sub-zero cooling builds just for overclocking records where long term pump out is not going to be a problem.

Thermalright Heilos is said to be a PTM7950 OEM

If I want to do some dust cleaning, can I just remove and then reattach? Cuz with thermal paste, we always clean up the old paste and reapply new one

Bought and tested, there is clear difference, although not up to my expectation. Maybe like 4-5c reduction on hotspot temp, 3c on core temp.

I butchered the installation, had a hard time trying to separate the plastic from the silicon layer and there was parts where I teared the silicon. Decided to just install it to see how it performs, it seems that it works quite alright.

Faster heat transfer doesn't mean you can get loads of improvements. Still depends on the cooler.

No instruction to keep in the fridge/freezer for easier application?

Can't open the link not sure why.

Anyway, i am thinking about the kryosheet as mentioned by bro babylon, it is like a permanent no need to redo since it can't dry up and pump out, but probably can't fill the micro space as well as paste? I like the idea of do it and forget about it, no need to headache.

Low power items ok. If you have a current intel i9 , then dont do it. It sucks compare to conventional thermal paste.

For laptops , i get it , because some laptops are hard to dismantle to access the heatsink , might break a clip or 2 at the bottom cover, for each attempt, so you want as less frequent thermal paste repaste as possible.

But for normal desktops users, nah ...

If you are a pc hardware reviewer , then it will serve u well , save u alot of thermal paste when u keep swapping hardware

You're supposed to throw the pt7950 into your freezer at night. Leave it until tomorrow morning when you wake up, use it and fast. Malaysia weather is not helpful.
I had the same problem with u initially, but the freezer method makes it easier to separate it from the plastic film.
Once u apply and power up the machine. Put load until it hits above 70C. Then you need to torque down the heatsink some more as the pad melts, thts the way to get the pad to fill microscopic gaps

not much instruction inside the box. already read in forums how putting it in refrigerator will help, but my impatient ass just need to see the improvement after waiting 1 week for shipping.

they have clear plastic and white plastic part. i'd say, release the clear plastic first, things will be much easier.

now after 1 week+ of application, I'm seeing further improvement. The fan RPM down by 100RPM. My GPU much more silent.

Bet your laptop runs silent after you clean all that dust

Yes, it runs much quieter now. In fact my big reductions in CPU and GPU temperatures I feel is more to cleaning out the struggling fans than the actual PTM7950.
Pasting the PTM7950, I tried the freezer method which made it easier to peel off and paste.
But end of the day my go to method to reduce wastage was to use the torn mangled bits and just tampal only.
I then just boot up my laptop for a bit to let it 'melt' into an even layer. Then just open back and readjust the paste.

I’ve just bought a large 80mm x 160mm strip of PTM7950 and will be applying it to multiple CPUs and GPUs.
Original price is RM84.27 before shipping, but I bought it for RM58.76 after vouchers & coins from Lazada

Since your laptop is already over five years old, you might also consider replacing the fans.

Look up the fan part number on Taobao, Shopee, or Lazada, and you should be able to find a suitable replacement.

Seems like you are the first buyer? Didn't see any reviews for the link. Was the product ok?

Haven't applied it yet
Sudden fever

Kryonaut vs PTM7950

I didn't clean the fans or heatsinks. I simply removed the Kryonaut with alcohol and then applied the PTM7950.
I cut the PTM7950 to match the CPU and GPU die size before placing it in the freezer & the Kryonaut was freshly applied around two months ago.





pandah FYI

This post has been edited by sHawTY: Sep 9 2024, 11:40 AM

wow max temp 20 degrees difference, seems like a legit product.

Hopefully can maintain for long time.

Kryonaut only 2 months can get to 99 degree, does it pump out? Or the heavy usage makes it dry up?

It's not Kryonaut issue, it's more of my laptop fan issue where when it tries to spin more than 80%, it screeches then stop spinning

I think the fan is failing, need to replace it

I forgot to mention that the "value" temperatures is taken during idle
With the PTM7950, the fans never have to ramp up to more than 80% so my laptop never overheats unlike with Kryonaut

This post has been edited by sHawTY: Sep 9 2024, 12:45 PM

So the heat conducting still seems better with PTM7950 despite both test carried with a broken fan

How laptop fan ramp up according to your cpu temp, if your cpu felt hot it will keep ramping up its speed because the heat doesn't get transferred efficiently to the heat pipe which goes to heat sink, the fan keep running without the anticipated heat for it to disperse.

it definitely is because with PTM7950 the fan speed never go beyond 80%
My laptop is also a lot quieter now

This post has been edited by sHawTY: Sep 9 2024, 01:37 PM

What model laptop u used on?

This post has been edited by zero5177: Sep 9 2024, 02:24 PM

A 5 year old Dell Vostro 5481

Temperatures are even better now.

My previous model similar to your spec changed to kryonaut grizzly also seen drastic change from 95c dropped to 70c+

Wow, is this with the new fan?

No, still using the old one
New fan ordered from Taobao, haven’t arrived yet

Can’t wait to apply PTM7950 on my wife’s ASUS TUF A15 (year 2021)
It’s still using the stock thermal paste

This post has been edited by sHawTY: Sep 13 2024, 02:40 PM

That'll be interesting! TUF heat up a lot

Has anyone else noticed temperature changes after switching to PTM7950? I'd love to hear how much of a difference it made in your setups!
It would be especially helpful if someone could share their temps when using this on a desktop CPU with an IHS.

Share your before and after results

A bit of correction: Lenovo uses a paste variant of the PTM7950, known as the PTM7958-SP, and they also use it on a few high end IdeaPads as well:
https://download.lenovo.com/consumer/mobile..._5_16_9_hmm.pdf

Note: I work for a company that handles HP(E) and Lenovo equipment

Any legit supplier/shop here selling it?

I do have some in my office
But I don't think I can send one for you

Unlikely to find it, but PTM7950 is close enough that we all can easily get

Where your office? I come nego tepi

Just buy from the Lazada link I shared before loh
Definitely genuine based on my before and after results

Just saw this part today.

Exactly! Just a heads-up—when applying it, try to do it in an air-conditioned room. You know how Malaysia’s weather is—hot and humid. Since the PTM7950 is a thermal material, it absorbs heat quickly, making it harder to peel off the plastic layer, even after refrigerating it overnight.

Speaking from my own experience, as soon as you take it out, it quickly softens when you handle it with your fingers.

Joining in the bandwagon as well. Been looking up for good thermal paste as gaming laptops really cook hard.

Device using: Acer Nitro 5 AN515-52 i58300h / GTX1050 4GB.

Initially I got a China unknown brand but highly reviewed on shopee, LK-17 which is said to have a thermal conductivity rating of 17W/mk.

First few month was doing great, but overall the laptop ran cooler despite for a mere cost of RM20 5g syringe. Both CPU GPU did not reach, say, 70-75 celsius under Acer Nitro balanced power profile. but when set to "Performance mode", it will spike to 79-85 celsius range, which is better than before repaste which could send it flying to 99.

After 2-3 months of using LK-17, things start to change abit, even on idling, it will spike to 50-55 celsius compared to initial stages as it would be always be below 50 no matter what profile I set.


So the time came, told myself what the heck, bought a 40x40mm PTM 7950 at RM16 (inclusive of shipping).

Not easy to apply on the chip dies, and not the fanciest despite putting it inside the refrigerator for 30mins.

Here is the results of using PTM 7950 for my Acer Nitro 5.

BEFORE:


AFTER:


CPU still can spike to 80+ range if I turn on performance mode, but under Acer Balance profile, I can see a difference of 4-5 celsius compared to using LK-17 when running Unigine Superposition Benchmark.


Also did for another laptop, Lenovo Ideapad Gaming 3 15AHC6/ RTX 3050, this thing can even cook up to 99 celsius during EXTREME test in Unigine.

BEFORE:


AFTER:



Will be monitoring it for a few more weeks/months to see if there's improvement as what they always said online.

This post has been edited by Omochao: Nov 28 2024, 07:07 AM

Done another round of Extreme and then back to Medium settings for my Acer Nitro 5.

Both cores stabilize under 70 celsius after sustaining non stop of 2 rounds heating.

Under ambient temp of 23 celsius air conditioned room.

Even the fans will turn to 0 RPM and running very silent under normal idling. Can hit as low as 36 celsius and idling hovering around 40-49 celsius which is really good temps IMO. Under load should be below 60 celsius, haven't really push for gaming as I don't really game nowadays, but with benchmark tools like superposition unigine, gpu and cpu still below 80 celsius which is very considerably good and nice.

With normal Malaysian weather, the cpu temps will hover around 47-49 celsius. No more thermal paste from now onwards.

also did a disable "Processor performance boost mode" under windows 11 power options.



Not trying to say the normal standard thermal is not good, but from using default stock paste which could made my laptop run 55-60++ celsius, now I can get better heat dissipation with this PTM 7950 thermal phase change paste. Highly recommended despite having a flawed heat sink where the gpu and cpu is interconnected.

Highly suggest that anyone who wants to change their laptop or mobile device paste should really go for this PTM 7950, no point buying Artic or Grizzly but then in the long run face pump out and degradation over time.

Seems like a great result, can share the link of purchase?

https://shopee.com.my/POP-Honeywell-PTM7950...c8-3ac9a671ae35

This seller looks very sus (err Doraemon?) and comes from China. FYI there are also imitation PTM which will work nearly the same as ori but later degrade faster. Anyhow I hope its genuine for you...

I did look on the reviews, so far no one mentioned about degrading even going as far back as 1 year reviews. If it really is, then is still worth it.

correct me if wrong,
aren't reviews on ecom sites all written soon after delivery of the item?
so you won't be reading updated reviews after 1 year of usage

By all means, if you doubt the price is too good to be true, you can always opt for the more expensive one if in doubt. There are countless of reviews being commented and not a single 1 star yet on this shop. The other person ask for a link, I just shared from where I got it from, I have no referral or affiliation with that store.

I'm interested in this so did some digging, searching for good source for the item

In lazada taobao collection section where its linked to taobao's sellers, only found like 6 different sellers on taobao collection though..
There's a popular benchmarker/tester streamer on bilibili (chinaYT?) called 极客温控/極客溫控 /GEEKTC/GEEKCOOLING selling phase his taobao store, another one is 星创热控 (sells on taobao & PDD).
Avoid GeekTC's aliexpress, someone created a YT acc recently took his old bilibili's video and edit out the outro where he promotes his shop to their aliexpress store. both aliexpress and yt is made a few months ago, doesnt make sense

Recently, whenever I turned on my laptop, i notice my fan will like ramp up to a certain speed compared to last time when I was still using paste, initially assume that the PTM I used was a fake, then I just remembered reading from reddit, that some people after repasting with PTM , need to re-tighten the heat sink screws again as the sheet might have flatten down a bit and thus causing less contact with the heatsink and the chip die.

So just now, took apart and tightened it slightly and make sure that the screws have no more turns.

Did another round of test, and even with performance mode, the temp won't spike even to 70-80celsius for the CPU.

Hopefully this PTM last long and I don't have to take apart for a long time to repaste.

Personally, I exclusively buy from 极客温控 on their taobao

got a link to them on lazada taobao? I had one long ago but they dissapeared

Almost forgotten to share another use case for another laptop in which i did for a Lenovo Ideapad Gaming 3 with Ryzen 7 5800H / RTX 3060.

Reopened it and try to tighten back the heat sink screw, but doesn't seems to be the case as I can only feel that the turns for the screw not much and don't want to risk stripping off the screw.

Run another Unigine Superposition test, with 1080p HIGH settings. And all I could say I'm really impressed by the thermals being done by this PTM 7950. All readings for both CPU GPU didn't even hit 70c at all

Laptop power options - Balance mode, with processor boost management set to disabled. Maximum processor set to 99%

Wonder why honey well don't wanna market this product here?

This stuff is not meant for us consumers its for industrial & OEM usage ie mainly on laptops & GPU heatsink. If you have the volume, Im sure Honeywell Msia will accommodate or at least point you to their regional distro.

if it goes mainstream and too commercialized, the price will definitely shoot up.

Yet another success story after switching to Honeywell PTM7950!
Just look at those temps!

The fans are noticeably quieter too—and I didn’t even clean them!

For Malaysians looking to use PTM7950 in our hot weather, here’s an additional tip:

Besides chilling the PTM7950 in the freezer, you can also freeze some water on a shallow plate. Once the water has turned to ice, place the PTM7950 on top of it while you work on removing the old paste, cleaning the heatsink, and fans. This will help keep the PTM7950 cool for longer, making it easier to handle during application.

With this method, peeling off the plastic film becomes much easier. Also, to minimize heat transfer from your fingers to the PTM7950, cover your fingers with tissue or another insulating material while handling it.

Hope this helps!

This post has been edited by sHawTY: Feb 26 2025, 02:30 PM

Or maybe just get everything cleaned & prepped then quickly take out of freezer and start to install? Putting on ice might cause tiny layer of moisture condense on the surface. Imho even if want to chill it while working, better to put on dry ice (the kind you get from Baskin 31)

ok to apply ptm sheet on the spider leg pattern kind of IHS of AM5?

just apply on the squared surface. Ignore the 'legs' protrusion.

one more question, can this be applied on AIO watercooling block?

I dont see why not. However PTM will stick stronger than TP so your need to really heat it up then quickly pull out the block.

Recently got myself a used laptop which is still fairly new. Acer Nitro V14 RTX 4050 with Ryzen 7 8845hs

Stock thermal paste by Acer was doing fine and could reach 42c on CPU / 43c on GPU, and was hovering around there.

Re-ordered PTM 7950 from the same previous seller. Did a repaste with full change on the even stock thermal putty with UPsiren UTP-8.

Temperature soared to 50-55 even in an airconditioned room ambient temp of 22c, thinking that it might be fake PTM this time, redo again for it and readjusted the thickness of putty and readjustment of PTM 7950.

End up same issue.

Then I notice that my heat sink is showing sign of thermal paste forming a square shape with the middle of the heatsink seems to be empty and has less contact of the thermal paste.

Silly me, must be that when I tighten down the heatsink, i press on it lightly and over screw too tight.

After rectifying all of it, here is the ambient temperature.


Will be sharing back on the feed back later with photos for my previous Acer Nitro 5 which was done almost 1 year ago. paste was still strong before I redo yesterday night.

Acer Nitro 5 AN515-52.

Idling/disable Turbo boost, under room temperature.

PTM 7950 is the only truly a good thermal solution besides LM.




This time no more retighten screws, just screw nicely and not too hard. let the sheet bond itself between the die chip and heatsink.

And true enough temperature is better.
