I bought a 1660 Super Ventus XS OC, I've already posted a thread some time ago discussing my issues with the overheating. I undervolted it to ~831mV compared to the stock 1031mV, and for a while, it helped. It floated around 65c, then eventually reached 70c, and now it's reaching 76c, playing the same games at the same settings with the same fan set-up. So, should I take the risk and buy some Noctua NT-H1 and change out the thermal paste? I want a permanent solution to this noise&temperature issue which has had me monitoring my temps for a few months now, but I'm cautious about the risk of voiding warranty, possible mess-ups etc, what are your opinions?
