Are thermal pads supposed to be this inflexible?

post #1 of 5
Thread Starter 
Today I received my pack of Phobya 1.5mm thick, 12 x 2cm thermal pad (7W), and I was surprised to see that this gray thermal pad is nothing like the very soft thermal yellow pad that was already used on the vrm's on my Rx480 card.

Are some thermal pads supposed to be this inflexible? I don't know if I should even use this stuff thermal pad. It doesnt seem like the vrm's make a dent at all into this thermal pad.

Testing show that the vrm' doesn't go above 84 deg C, but somehow I think this is still too high.

I have the old yellow thermal pad saved, in case I want to re-apply it.

Edit: On some webpage that sell the same stuff I find the following description "Please note: This thermal pad can be compressed down to half of their original height."

Are you running the card under a water block? When I did mine, I used Fujipoly. They were grey soft pads. VRMS never go in the high 50s. most of the time they remain in the 40s on load. You get 80C+ yikes.

Nah, I run everything on air.




I removed the Phobya pads and did two things:

I put the old yellow thermal pad back
&
I added some custom made washers to the two screws for the "vrm area".

Now, the temps was 67 deg C at maximum after some hour of gameplay. Nearly 20 deg C cooler than previously. Maybe because of lack of tension, but also, I think the Phobya pads are useless for my needs here, as the screws and all seem very delicate.

I noticed that the gpu temp was also max 67 deg C, but maybe that was coincidental. smile.gif

The temps was measured with the HWinfo64 software.

Thank you. smile.gif

I ordered some metal and silicon washers on eBay and will replace my custom styrene washers when I get them in a couple of weeks or so. I will have to keep an eye on the styrene washers as they will melt if the temperature get too high. Unsure if that could ever happen, but better safe than sorry.

I have solicited Asus fo getting some spare parts (two screws w. springs, presumably there are loose springs with the two "vrm" screws), so that I can get to use the proper screws, which in my case I think is supposed to have springs on them, but I suspect the fell off without me ever noticing it.
