Maybe i need to upgrade my cpu cooler, or going to water cooling maybe the better idea...
I wanted to go the water cooling way myself, but because it was above my budget, I bought a Noctua NH-D14 for 65 euro's. I overclocked my Q6600 to 3.2 Ghz and my temps never go higher than 52 degrees (that is the temp of my hottest core) during Prime95 Blend test. I was pleased with the results. It's much cheaper than a good watercooling setup and it's almost noiseless.
