0c delta between water and core?

post #1 of 11
Thread Starter 
I apologize if my terminology is incorrect but currently my water temp is at 26c and my idle GPU's are at 26c each. I am using heatkiller x3 gpu blocks and I was wondering if it was normal to have core and water temps so close? I was under the assumption that a 3-7c delta was REALLY good at idle. Under load my delta is about 5-6c because my water temp will usually go up to about 32-33c and my gpu core temps will be about 37-39c...with the occasional 40c under normal gaming loads. Was I lucky enough to just get a really good seat b/t my blocks and gpu, or is this just to be expected?

How long did you let the cards sit at idle? what are your ambients?

My water temp is about 3-4c above ambient it's currently 72f in my house and I don't have te conversion in front of me but that sounds about right. Been siting at idle about 2 hours

With GPU-Z I see two gpu temps, one is around water temp and the other shows about 5 degrees higher.

I was just playing a little TF2 for a while and my water temp went up to 28c and my gpu's were at 30-32c. I had vsync on and they even downclock themselves because the video load is so low.....kinda make me happy. OH, I have a 360 and 240 rad. only 4 of the 5 fans are running because the potentiometer died so it stays on full blast which i cant stand so unplugged it remains. All other fans are on low.

Probably like that because of your rad overkill lol. Very nice.

I think it has to be a discrepancy between the different thermometers involved. There is no way that the CPU could be at the same temp as the cooling fluid even if you had a perfect conductor as a CPU water block.

LOL. Not really rad overkill. Everything on my rig except for the ram is wc'd. nb and sb included. So its not that bad of rad overkill....then again, there is no such thing as overkill on OCN!

No no, CPU is not the thing with a 0c delta, The GPU's are. The cpu idles at....lemme check...31-33c across all cores.

Same thing. Doesn't really matter if we are talking about CPU or GPU. It's still technically impossible. Unless your GPU is off...
