Thermal Paste help!

[chancy]

I replaced my laptop's thermal paste with Arctic Silver 5 the first time I did it I might have put too much, the second time I did it i put enough for the laptop. I know the cure time is 200 hours but shouldn't there already be a difference im getting a idle temp of around 70C and full load goes up to 84C the first time it actually shut down on me but I don't know if its because of the cure time or if I am doing sometime wrong, any help would be appreciated. Thanks!

Welcome to the forums!

 

For a bare CPU die on a laptop I usually apply a small length along the die but also it depends on the cooling solution and CPU you have on hand. The difference in temps for the silver compound after curing is usually ~5C from what others results have seen.

How would i go with applying thermal paste on the surface of that?

Same as any regular CPU by apply a pea or uncooked gain of rice and cross threading the screws on the cooler to ensure even pressure, using the spread method can introduce bubbles in the thermal compound causing the temps.

Yea i know the risk of using spread method but im afraid about the heatsink not having enough pressure to do so, anyways I'll try it and report back hope it goes well. Anyways i should add that this is not my main laptop this is my old one that i want to install windows 10 preview on but i couldn't because the laptop would overheat. Since the temperatures are around 70C do you think it could go even lower in idle even with a 200hour cure time?

I've seen it go down ~5C after curing but I assume from that photo this is an older processor, which can produce more heat and probably a not so well designed heatsink back in the day.

That's way too hot; Cure time only makes + or - 5 C difference. 
Do not use the spread method; that's dumb.

Yea now that I think it's most likely the spread method that gave air bubbles I'm just gonna stick to squeezing thermal paste out and letting heatsink do the work, thanks all for helping me I'll keep you updated.

ok the first image is the 2nd try with the spread method when i put thermal paste the 3rd picture is what i just did but the temperatures seems to be the same as before.

That's a fair bit of paste on the secon  on with the gain of rice method but also I notice that you have an older removable CPU, and that heatsink uses the metal edge to do the heat transfer which isn't the most ideal. It's probab;t the fact that it's an older CPU and not the best designed cooler that's causing such high temps but what was your temps before doing any work on it.

The temperatures were pretty much the same except that it would go really high straight away since the old oem paste had dried up and cracking. I've just about given up.

Then the new thermal paste keep it at a reasonable level and not shoot up straight away, being your cooling solution on the laptop itself wasn't designed very well or the GPU and GPU output a fairly large amount of heat.
