I didn't think you are required to watercool MOSFETs anymore. I mean I had to watercool my 780i chipset and MOSFETs to get my Q9650 to 4.1Ghz but my 2600k runs perfectly fine at 5.1Ghz without any problems on my Maximus 4 Extreme. Factory heatsinks installed.
Watercooling MOSFETs must be a cool kid thing now!
We need someone to bench OC limitations of MOSFETs while overclocking while using radiator fluid not, over the top dumb dry ice or whatever. Because my MOSFETs are only reading 41c load
