The bottle I got from the all IT hypermarket was dry..

Argh...

Then, what did you do?
Didn't ask for refund? [can refund ka? sweat.gif ]

If it's dry, then it's useless liao...
Hmm...

There is another way, but not sure if it'll work or not...

Why don't u use a lighter and try to reheat the base of the zalman thermal paste bottle?

Not sure if it'll work or not, but it's worth a try... thumbup.gif

is the oxide layer good in transfer heat?

or is it will become heat insulator?

No, it's not good in transfering heat.

ID86, can't u do google? sweat.gif

If u wiped the paste with normal tissue, or dry cloth, then i think it'll be okay...

But since u're using wet cloth to wipe it out, i don't have a good answer for it...

Kinda scary too... sweat.gif

***Why did u use a wet cloth to wipe it out in the first place? sweat.gif

abg moderno,if the paste become "keras",is it any solvent (pelarut) that can bring it back to the exact form likeu said semi solid-semi liquid?

Now this is what we call "Good Question"... thumbup.gif

I was about to ask the same question oso...

So, moderno, can you answer this question?
How to make it not hard again if it's hard? blink.gif

is it have other methods other than lapping to remove oxide layer or dont want it to form?

U can use ACID...

It'll work!!!

But it won't just remove the oxide layer, it'll even eat some of the aluminium... laugh.gif

Oh ya.. i used alcohol too... wipe the core and the component arround it.  But i worried i will 'eat' the core.. becoz the core is like plastic material.

I don't think that Alcohol will eat the core, anyone can explain this further?

**Beside, if alcholol can eat the core, then that means Arctic Cleaner is dangerous liao... laugh.gif

what type of acid can be use,low or intermediate concentrated?

can use the high concentrated acid?

Hey, i'm just joking la...
Don't use acid, it'll eat the heatsink liao... sweat.gif

Just use arctic cleaner to remove the oxide...
Maybe it'll work... thumbup.gif

Or why don't u do some simple lapping to remove the oxide? wink.gif

OMG seems dangerous .... anyhow using alcohol that used for cleaning tape will do just fine...

of course professional way is to use Artic Cleaner....

anyhow don't be to worry as the core is well sealed shouldn't be too much of problem ...

I used CK ONE [Calvin Klien] laugh.gif

Used it hundreds of times to clean my processor, gpu core, northbridge core, nothing happen until today... laugh.gif

As much as I would like to compare it, its sad that I don't have the Nano with me during the time of review.
Btw, next time don't advertise in your post. Move it to your signature...
Yup... because NVIDIA used ShinEtsu thermal paste I guess. Its quite thick, hard and silver based too. AS5 did quite well, even without properly curing. If any of the TIMs could do at least 1ºC better than the stock TIM, it's already pretty damn good.
*
So then, let's wait until a couple of days for those "expensive" thermal paste to sink in...

Who knows either they'll work better than the stock TIM or not... thumbup.gif

Yup... I will retest the STG1 in a the next few days.
As for AS5, I will have to reapply it and wait another 1 week... darn time consuming... LOL. Arctic Silver said it needs 200 hrs (about 8 days) to properly cure in.  doh.gif
*
8 Days!!! shocking.gif

Do you think that the STG1 also need that time to cure in? sweat.gif

overclocker paradise is selling AS5

edited (Off Topic): is there any special method to apply zalman ZM-STG1? i just got that from moderno and after i applied it, my processor temp is higher (4-5c) than previously. before this, i used stock grease from intel. is it i need wait it to sink in before i can see the difference?

1. i used artic cleaner to clean my processor.
2. i put the grease on all the surface of the processor.

any problem with my application? i already checked the processor heatsink, it is properly intact.
*
Wait for a little more days..
Who knows either that thermal paste is just like AS5, need time to sink in before it perform to the max... smile.gif

Right? cool.gif

I never applied any thermal paste on both part...
Only applied the thermal paste on the processor's IHS...

Don't know about zalman thermal paste though, if i were to use the STG-1, do i need to apply on both surfaces? blink.gif

i applied both side too... it is written at the bottle itself and on the official website. hopefully it will bring down my temp after seven days else i think i just threw my RM32 into the drain. haha..

Hey, if it fails you, dont threw it away, give it to me liao...
I'm in need of thermal paste now, finished my AS5 aedi... laugh.gif

that really looks like liquid paper in a bottle. tamiya cement seems to use similar bottle. heehee.

i was wondering, do you people actually reapplies the thermal paste after a while? i havent actually taken out my hsf for reapplication since it was stuck there.. 2 yrs possibly, definitely more than a year, and i cant really see temps increase. im also wondering about how long does it takes for tim to deteriorate.

currently running at 245fsb 2.9, double prime would currently still be at most 61, mostly 60, or 59 if ambient temp is cool, or 58 during rain + opened windows. and those are the very same readings i got after er.. probably 3 or 4 days after applying the thermal paste. initially it was higher, i primed immediately after applying, then cool off my pc for about 3 hrs, then primed again, for maybe half day, then cooled off.. then normal usage.

using as5.

Now that's weird...
After two years and there's no increase in temps? blink.gif

Two years you didn't take out the heatsink?
There must be a lot of dust accumulated there... sweat.gif

QUOTE(irangan @ Dec 5 2006, 01:03 AM)
probably i can sell to you cheap cheap since i only used once smile.gif

No problem one, can always discuss it through pm right... brows.gif

Wait a couple more days la, see how it goes... smile.gif

i didnt take it out. i cleaned it regularly though.. use brush, n blower. the heatsink is dust free, but the issue here is the tim.

Owh, my bad then...
But still, after two years, the TIM should deteriorate? No? smile.gif

Weird thing is, you didn't experience any temperature increase even after using it for two years... sweat.gif

You can choose either to use thermal paste / grease on the notebook or not by you're choice...

Normally notebook manufacturers didn't bother to put any Thermal paste / grease between the processor and the heatsink...

I've repaired so many notebooks, and open a lot of their casings [i only open the notebook casings that the warranty is over already laa laugh.gif] and none of them uses thermal paste / grease... smile.gif

Every notebooks that i've opened, i'll put some thermal paste on top of the processor die, coz this will help more in transferring the heat to the heatsink...

So my suggestion is, put a thermal paste, it's better that way... smile.gif

Ahh, another thing, if u look on the heatsink, did you find somekind of metal zink sheet?

If you do, take it out, then clean the heatsink with some alcohol, then apply the thermal paste to the processor die itself...

The themal paste will work better if you take out the metal zink sheet... wink.gif

Ohh, and by the way, you don't have to use AS5 for notebooks processor as they are cool enought to be use with those normal white thermal paste... thumbup.gif
