Ausu PC probe - idle 35 Load - 56
Intel TAT - idle 50/50 Load - 63/63
The cooling im using the the Thermaltake Kandalf LCS case with a built in water cooling kit.
Eidt: these temps are with the comp running @ 3.4
I would be more inclined to trust TAT readings, but even if you take an average, it's about 60°C full load. Personally, I would consider this temperature to be a little too high, as Intel specify the max operating temperature for the E6600 as 60.1°C
. Running the CPU above this temperature could mean that it may throttle (lower it's speed automatically) to prevent damage, which will mean that you won't always be getting 3.4GHz of processing out of it... Still, the Intel thermal specification is taken at the IHS
(for CPUs that have them) so perhaps the TAT temps are less important in this instance? Anyway, 3.4GHz is a 1GHz o/c and imo is pretty damn good. A P4 would (roughly) have to be running at around 6.5GHz - 6.8GHz to match that and then it would have less cache...
Did you use AS5
as your thermal compound? If not, it might be worth getting some and using it in place of whatever other thermal compound you might be using. AS5
is generally accepted to be the best thermal compound you can buy. It takes about 200 hours of operation (with some cold periods when the PC is off) for AS5
to take full effect, but it's worth the wait as it can result in 2°C or more lower temps (compared to the initial application), which can have a positive effect on o/c'ing.
It's difficult for me to give you any specific advise, because I don't have the same board as you, but in general, you just need to play about with the settings and eventually, through trial and error you'll find a combination that will yield the best results. You've already got a higher stable o/c with slightly lower voltage than listed in your original post doing just that
On water cooling, I expect that up to 1.55v v-core is OK, but in general try to use as little additional v-core as you can to get a stable o/c as it can cause long term damage if you use too much over an extended period of time. Not only that, but heat output is greatly effected by voltage, arguably more so than MHz in many cases.
Good luck with your o/c'ing and let us know if you managed to improve your already decent o/c
