thermal grizzly conductonaut not giving amazing results

[rfcokilljoy]

hi, i just replaced the stock thermal paste on my Palit GTX 1070 ti Dual Fan with thermal grizzly conductonaut. I expected to see obvious differences but i am seeing maybe a 1 or 2 Degree drop? its barely noticeable. I applied the paste as similarly as i could to examples online. Is there any other reason for this? or should i take it off and reapply it again (hopefully better)

 

Thanks

For all GPUs, they have no IHS, and their coolers directly cool the silicon die. So the results you're seeing is to be expected of GPUs.

 

The temperature drop is not going to be as earth-shattering as doing a delid and applying liquid metal onto the die and the IHS of a CPU, if done right, and under the right conditions.

On GPUs, there's little reason to use LM. The heatsinks are massive and have a lot of hugenorous heatpipes to carry heat away from the die and it's already direct-to-die cooling.

thankyou so much for your replies!! I understand the logic you both are talking of.

 

1. 

- in this video the temps drop by 10 degrees? how come?

 2. Is my heat sink big enough? you can get a good idea from the pictures through this link, and i know there are 2 copper heat pipes. - http://www.palit.com/palit/vgapro.php?id=2935&lang=en&pn=NE5107T015P2-1043D&tab=ga

Just watched the beginning and when i saw how much thermal paste there was i can tell you that it was way too much, thermal paste is one of those cases where less can be more in the end so i guess on your card there was exactly what had to be there and a non shitty paste.

ah, thankyou  im glad to know nothing is wrong. 

 

thanks for your replies.

2 things here, the first being it's entirely possible that bad TIM / application will effect before and afters. The second is that in that video he went right from factory TIM to TGC. Just by the looks of it, the factory TIM looked pretty crapfabulous. He could have had just as good results just by using a quality TIM.

Thankyou, nice to know nothing is wrong then! Phew!

They probably use a custom fixed fan curve. If you have the automatic fan curve set it only means the fans would spin a tad slower for achieving the same result. If you really wanted to see the difference i would put the fans with stock paste on 60% and then do the same with LM. Then you would probably see a bigger difference but i still wouldnt count on it beeing a lot more than 5 degrees

Could also be very likely part of the issue did you watch fan RPM before and after or noticed it being run quieter ? Usually curves are set depending on temps so it maybe now need less RPM for same temp

Unfortunately I used 60% both times looks like those scoundrels at palit put the right amount of paste on

it happens... rarely, but it does.

Than the original paste was good enough. The point of thermal paste is to fill minimal defects on the surface of the cpu/gpu. If it is machined properly and already making good contact with the heatsink, thermal paste should have very little impact on the temp itself.

 

Imho good thermal pastes and the apllication methods are a bit overrated. Even if you put "too much" on, if the gpu and heatsink are machined properly it should thin it out exactly as it would if you put a thin layer on. Problems only occur if the TP itself is conductive and the exces bloob spreads around the chip. Otherwise even aplication methods are overrated. I have never in 16 years building computers seen a mention worth difference in temperatures after changing thermal paste, except if the stock one was very dried out.

 

You could probably see a bit of difference if the stock paste was very very poor quality, with bad thermal conductivity but i highly doubt palit or any other good manufacturer would use bad paste on a high end gpu
