Water temp rised in SLI

post #1 of 5
Thread Starter 
After putting my second GTX670 FTW under water, I have experienced some changes in temperatures that bother me a lot.

When I only have one GTX670 my loop deltas where: 2ºC idle, and 8ºC full whatever I did.
CPU was hitting high 50s and GPU was always under 45ºC. Fans where varely spinning so the sistem was incredibly silent.

Now, I have to have fans spinning @ medium speeds and I do not like it at all biggrin.gif
I have registered an increase of about 15ºC on full load (2 hours of Crysis 3) wink.gif

My rads are 1x Alphacool Nexxxos XT45 360 (3x Noiseblocker NB-eLoop B12-4 in push @ around 1200rpm) +1x Alphacool Nexxxos UT60 240 (4x Corsair SP120 in push-pull @ around 1400rpm).
GPUs are not overclocked. CPU is a 3770K @ 4.0GHz, vcore=1,1v

Is this cooling performance OK?

I apologise for my bad english!

So you added more heat to the loop, and your surprised temps went up a bit?

Agreed. If you want to turn your fans back down get MOAR RADIATOR

I consider a 15ºC increase in water to be a bit high for just a second GTX670. I just want to read opinions from skilled watercoolers.

Thanks in advance

I think the general rule is a 240 rad per block. So i think your starting to push your limits a little with that second GPU. I know i can warm up a 280 and a 240 rad pretty good with low fan settings with just CPU and 1 GPU.
