im looking for advice regarding water cooling of my gpu's. I know it probably isnt very cost effective for mining, the reason why im doing this is so i can move 1 or 2 rigs to work where electricity is free. The problem that i have is that it's a pretty small office (12m² ~ 129.17ft²) and it can get very hot overnight and i'm not allowed to have the window open when im not there because then the alarm will go off.
So my question is:
1. Would watercooling solve/lower the exaust heat?
2. How about noise? I'd like to keep it to a minimum as it is a workplace and it would be annoying to listen to all the fans blowing.
1. No, you will produce the same amount of heat. It just gets moved out of the computer and into the room faster.
2. Yes, it can significantly reduce noise. I have two HD 6970's that sounded like hair dryers at full load. Now on water you can barely hear anything.
1. Are you sure about this? It doesnt compute with me how can a GPU that's on about 45C generate same amount of heat then a GPU on air with 80C for example?
2. That i like
1. Yes, 100% sure. The video card uses the same amount of energy no matter how you cool it. The GPU is generating the same amount of heat. The reason it may be 45C when water cooled is because the water efficiently moves the heat away from the video right away. The radiator then can quickly transfer that heat to the ambient air.
