Well I took the leap a few days ago. Thermaltake Water Performer 2.0 and a Sapphire R9 290.
Now I'm here to troubleshoot a little.
My computer boots just fine, and seems to have to issue running idle, resting at temperatures around 40C - 50C. But under load it's unable to handle itself whatsoever. Playing a game will skyrocket it past 95C, and even a video will heat it to above 70C easily. But after the programs are shut down, it plummets right back down quite well, leading me to believe that the mod went off just fine, it just wasn't enough.
So, here are the potential problems I want to address here:
-I only had 16 copper ramsinks, which I used entirely on the vram surrounding the core. The VRMs still remain bare, and need to be entirely cooled by case fans.
-Water Performer 2.0 is getting a little outdated. Always a possibility that it simply won't be enough. If anyone has experience here with this model, please let me know.
-I had four fan cables that needed power, but only two outputs on the motherboard. The two radiator fans came with a Y-splitter cable, which took care of both of them. I had also used this configuration on this motherboard before without issue, so this was fine.
Next I had to attach the 4-pin cpu fan to the 3-pin case fan output, which should be backwards compatible, and seems fine, but this left the pump still to be attached. Some weeks prior I had ordered a molex - 3-pin adapter, but it still had not shipped, and would be at least another two weeks to receive it. So, the solution required a bit of creativity, ingenuity, and stupidity. I had a spare molex-sata adapter lying around unused, so I googled the pinouts, stripped the wires, and fitted it to the 3-pin cable. It didn't allow for any control or PWM, but it got it the 12v it needed, and seems to be running fine.
This all of course, led to the configuration being somewhat convoluted, and it may leave quite a bit of room for error somewhere inside. One obvious problem being that the radiator fans are now controlled by the CPU temperatures, rather than the GPU.
This leaves a number of problems that I have little way of testing on my own. I have tried using both speedfan and the BIOS fan controls to adjust the fan settings to match the GPU, but it has yet to have any success. Really any help would be appreciated, since I've been out of commission for near to a week now, and would hope for some returning functionality soon.
