Are these GPU temps to good to be true?

After finishing my water cooling build and a couple tweaks and leaks. I finally managed to get it running well.

The thing is these GPU temperatures seems to good to be true.

This is my Radeon HD 7950 (GPU1) running at stock speed with the power limit set to -20. On air at those settings it ran at 80+ Celsius.

My loop is setup is Res/Pump ---> 360 Radiator (Push Fan) --> CPU --> GPU1 --> GPU2 --> Back to Res/Pump

Any feedback would be appreciated.
 
Nope that's normal, that's one of the water cooling advantages right there. :)

I usually sit sub 45c but I have one less GPU and more radiator.
 
Good to know. It was originally sitting at 80-100 Celsius until a fiddled with the water block and screws.

I never been more nervous until I finished this project, but now its cooler and more quieter than before.
 
Yes, it's very important that the mating surfaces of the block and GPU/card be as close to perfect as possible, which it sounds like you figured out ;)

I understand, it can be nerve-racking at first, but once you get over that it's just bliss. Welcome to the club and HardOCP! :)
 
GPUs can run hotter than CPUs normally, so manufacturers won't spend the extra money for cooling. Once you add it to your loop it will be much cooler than stock fan. My 580 GTX is running at 30C right now in my loop (idle) and I rarely see it go much higher than CPU (around 40C).
 
You just saw the two main reasons to water cool, silence and lower temps (Huge downside of cost .... dont ask how i know lol)
 
Am I reading that right, power tune minus 20?

Yes since the original coolers were pretty bad and noisy as hell on top of that. Lowering it power limit caused it to not run as hot.

The cards usually topped out at 90 Celsius before I water cooled it.

These are the cards I use. Just a single noisy fan.
