I recently bought a GTX 670 FTW. Loving it. Great performance, etc. However, it's very noisy, compared to my other components. I literally can't hear my PC when it's on, even with no other noises. However, the GPU is very loud under load.
I understand that the fans need to spin up more, but it is pretty darn loud.
Could anyone recommend another cooler solution? I've looked at water-cooling, but I've never used it before, and I really don't want to spend more than ~£80 (Ideally max £60). Would another (air) cooler help much? Note that my GPU only lets me spin the fans 30-80%, anything below 30% sets it to 30% and another above 80% sets it to 80%. My temperates are fine; roughly 68ºC under full load. Note that I do not have the SIG 2, only the original FTW.
Also, just to clarify. Installing a custom cooling solution does not void my warranty? Reading the warranty seems to show that as long as it's sent back with the original cooler on it, it's all good.
Thanks for any help!
