What thickness for thermal pads can I use on GPU VRM chips for Acer Predator Helios 300 (PH315-52)?
Answers

That's fine, I have spikes till 79C and 74C in average0
-
I found that if to place a mouse cursor over Package Temperature section, it shows statistics
I downgraded to old version of XTU and my max temp is 79C (recent maximum)

You know I tried to apply Noctua NT-H2 instead of Grizzly Kryonaut and so far results just excellent
With the fans on auto at 2600+2900 rpm and with PL1 56W, I have stable 4Ghz in XTU stress test and temperature peak 73C and average 66C
Will check how it will work with the time, Kryonaut had a tendency to get worse after several days but so far I am a fan of Noctua paste

Yes Noctua is great...bdw i turned off short turbo boost and i have zero thermal or power throteling and my temperatures are just a flat line ....its so nice to see that

And made in Taiwan btw
But you didn't have thermal throttling anyway, did you? You could have only power throttling and only in specific cases when system wanted to get above 56W, I know only prime95 can do it, it needs 62-65W to run at full 4ghz. XTU needs only 52W which fits into 56W limit.0 -
Zero thermal throttling its perfect now....so stable nevwr seen this before on other laptops 0
-
And I checked footprint again and again conclusions the same, three chips ok with 0.5mm and for other three 0.5mm is too little but 1mm is too much so on those I used 0.5mm with some paste under, will see how it works with time

I did according their instructionszerophyte said:Question for ya @belik
how should I apply my noctua nt h2 paste? Pea dot in centre of gpu and cpu or X pattern? Or should I spread the paste all over the die?
Put one dot 3-4mm on the center cpu and one dot on the center and four small dots near angles on gpu0 -
I reccommend this kind of pasting over dots. My temperatures in aida 64 after 1h fans at 4500rpm 60'C0
