Arent those high for water cooling?
I'll try mine out at 3.5ghz @ 1.4 (if it is stable for me) and see what I get. I did play with 3.6ghz and was touching upper 60's with prime after a few minutes.
In the big scheme of things though, all these problems coupled together add up to being about 200-300Mhz less than ideal 24/7 OCs. A 3.5Ghz Q6600 is almost grossly powerful for a mid-range user who isn't doing 3D modeling or video encoding. My DVD encoding doesn't even have a chance to stress my CPU - it is done in 3 minutes! For gaming, under the most intense conditions my core temps never reach more than low 60s.
So, my temps are not some of the best watercooling temps out there, but I am not using one of the best watercooling rigs out there either. I wanted a quiet, attractive solution to heatsinks+fans - my sacrifice being those few extra hundred Mhz. I know we at OCN hunger for more and more power, but just like cars - you have a project car and a daily driver. My watercooling rig is a daily driver and isn't tuned to perfection for lower temps.
For now I will continue testing speeds and voltage - trying to tweak out 20mhz here, 50mhz there. But I know when I play BF 2142, it is nice to see FRAPS hit the 100fps cap and never dip below 90. (Or to see that in F.E.A.R. maxed out my fps avg is 160!).
As it stands I got what everyone on the forums told me I'd get: A pretty looking watercooler that delivers mid-range performance, similar to high-end air cooling. The only difference being I have only 3 fans in my case, it is 100% silent when I'm doing law stuff, looks pretty, and my case temps rock!
