I've been reading all kind of opinion on thermal pad pasted at the back of the GPU, most of the comments I have seen were negative but call me stubborn, I wanted to make up my mind.
So i bought this ultra cheap (<1€!) pad : <a href="http://s.click.aliexpress.com/e/FIqFE6M
">Thermal Pad on Aliexpress
And guess what... it worked!!
Here is a picture before applying the pad
GPU is most of the time hotter than the others, I don't know why but I decided to apply the pad there. Temp here is 56°C
Look at GPU 2 again, temperature down to 51°C
I'll leave it like this for a while to see how it performs and then try it on another card. If it succeeds again, I'm definitely going to buy some additional ones.
Any similar experiences?
