Reapplying Thermal Paste

[virtualgravity]

My Zotac GTX 970 temps reached 74-75 celcius during gaming and peak at 78 celcius in furmark test (ambient 25 celcius)

 

I've tried to reapply the thermal paste of my GPU but somehow the heatsink is very hard to took apart (with all screws removed).

 

Should I force open the heatsink? I'm concern about my thermal pads since I don't have any spare.

 

and do you guys think that Noctua NT-H1 is good enough for my GPU?

 

Thanks before.

No

 

Unscrew heatsink, make sure it's the correct way (counter-clockwise)

 

Are you sure you want to void your warranty?

I already unscrew all and somehow it still stick pretty strong as if something is holding it down. For better temps? sure

Sorry, but I don't muscle anything in technology

sometimes the are held on by a vaccum, and twisting the cooler a little bit will free it, but if it doesn't twist freely, you probably haven't removed all the screws. check for one by the output ports.

those temps aren't necessarily uncommon for a GPU, my 760 had similar temps, with only a 1-2C reduction from replacing the TIM; i just got frustrated with the cooler and swapped it out for a corsair H55 (quite an undertaking, not recommended unless you really know what you're doing) and that dropped temps by over 30C.

in my experience, the major limiting factor with GPU cooling is the coolers themselves, as they aren't able to be oriented in an optimal direction like CPU coolers do, and often have to dissapate between 2 and 4 times as much heat, where for the CPU it's usually the small dye and crappy TIM and heat "spreader" that limit the cooling.

Yeah pretty scary considering it cost hundreds

So the cooler do move a little while I twist it but I'm afraid if I twist to much the thermal pads will be unsusable . I'm just curious because some manufacturer apply too much TIM to their products

Almost if anything thermal pads will be ok to reuse. They aren't anything special. They are there to prevent certain parts of the chip from overheating or heating a delicate part directly.
