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.

Gigabyte RTX 3070 Ti Gaming OC thermals like shit and no room for OC since brand new. 2 years later, it started to crash due to hotspot temp. Did everything till today I decided to change the thermal pad and paste.

Original thermal pad and paste seem to be low quality lol.

Changed to PTM 9750 (not sure original or not) & some thermal pad I bought from Taobao and heres the result.




Product:
Thermal pad (1mm & 2mm)

PTM7950

Err the seller just confessed it aint original, likely a Chinese branded clone. As long as its a grade A clone and installed properly it will prolly work liked ori in the start but will degrade faster with time so your not able to see any diff for now. Enjoy it while you can but you might be changing out sooner than later. For better or worse do keep us updated your usage.
