Arctic Silver 5 on GPU

[Dirk Diggler]

When I first got my G1 980s I decided pretty rapid style that I'd be putting them under water as I prefer as near to silence as I can get and with SLI on air that wasn't possible... Or so I thought!

I recently took the blocks off them as I put one in my second rig and intended to sell the other. When I put the air coolers back on, I used Arctic Silver 5 and wow, what a difference!

In SLI with a 25mm gap, one card peaks at 59c and the other at 69c, 50% fan and 70% (quite noisy TBH). I've just split them again and a single card is barely creeping above 60c at full pelt on a continuous Heaven loop, 50% fan which is barely audible.

I can't believe the difference the TIM has made.

It's amazing the difference replacing the TIM can make, as you've noticed


I've replaced the TIM on my reference HD7950. With it overclocked to 1.2GHz, it sits no higher than 82°c under full load. Obviously still rather toasty, and it does get pretty noisy as well, but it's still a good 6-8°c better than the stock stuff.

Trusty old AS5. Love the stuff.

noctua NT-H1 is also really good and not too expensive, thats what I use on the gpus

The thing I dont get is why my graphics card is like 5 degrees above water temperature and my cpu is like 60 degrees above, it can hit 100 degrees in prime sometimes under water

It should not be hitting 100c at any time, you have too many volts running through it.

If my CPU goes anywhere above 90c during IBT runs then the volts come down. As for Prime, I've stopped using it.

Am I the only one who's misread that as "trusty old ***"?
