Done the mod, partially at least, because its not finished. I put my Asetek 760GC CPU+GPU WC kit cooling only the 2500k @ 4.3Ghz (while I wait for my other 670 to arrive) and a Asetek 740GF GPu WC kit cooling my 670. I put some heatsincs on the gpu ram, mosfets already had it. In the photos you can see the PCB lenght difference between my old 570´s and this new 670, they must have been 1/3 bigger. I am not very good with cable management but when I put the other 670 I will try to do better
My results are pretty impressive, my gpu idle temp is 25C (room is at 17C) and my CPU at 35C. On load GPU gets to 43 smf CPU to 53 but My GPU fan dosent rise from 30% so its very quiet while gaming/benchmarking. My old top and bottom cards in SLI would get to 35 and 28 in IDLE mode and 97
and 72 degrees while gaming so I am very happy with temps. Also like the fact that I now get 9000P points in 3DMark11 with only one card, when I used to get 1000P with the 2 570´s.
The only thing I certanly o not like is the noise while in idle mode. I have Noctuas NF-F12 PWM on the Asetek 740GF connected to the CPU_1 and CPU_2 MB headers and I have a Gentle Typhoon AP-15 on the 740GF, connected to the 3 pin header on the watercooling kit (it´s suposed to control the fan automatically, confirmed bt Asetek support). Also mounted with zip ties a 92mm arctic cooling PWM connected to the VGA fan header, with the respective adapter of course, along with the kit pump. I connected the 760GC 3 pin pump connector to the 3 pin PWR_1 MB header and the sensor reports it at 1450 rpm. The CPU fan RPM sensor is always at 750 RPMs but I hear a fan spining faster when I start the PRIME 95 stress test.
What am I doing wrong? Should I ditch the noctuas and buy another 2 gentle typhoons, connecting them to the 760GC 3 pin headers which I am not using? Should I connect the fans to different headers or someting? I really want to reduce the noise, that was my purpose from the beginning...
And I want to thanks for all the help and ideas you´ve been giving me. Edited by Paps.pt - 5/11/13 at 5:26pm
