Hello,

I've got a Q6600 Stepping G0 with Bigtyphoon VX 120
Also I've OC my cpu to 3.4ghz

on idle my temps are between 39-42c about 4 cores
on stress testing it can gets up to 68-72c

Is this normal?

PRIME95 for stressing and CoreTemp for temps.

thanks.

Inproperly attached heatsink? Voltage to go to 3.4Ghz? Reattached the heatsink and if that doesn't work lap the heatsink and cpu if you need to.

1.385V to CPU
I reattached in the past the heatsink few times(Intel attaching is very stupid in my opinion, even if you attach it well it still not 100% solid stick)

Anyway are the above temps not good?

Lapping will overrun my warranty right?

I'd say those temps are perfectly fine. Everyone sweats when they get a core that goes above 65*C, for absolutely no reason. These are quads, they run hot in all but the most well ventilated setups. If you're running Prime95 for around a half hour to an hour, and your hottest core is below 75*C, you're golden. I hear so many people say "detach heatsink, reapply paste, reattach heatsink." It sounds like a broken record, and 9 times out of 10 it makes absolutely no difference, and only causes headaches for those involved.

Case in point: I just did a Q6600 build for my brother, gutted his old Falcon Northwest Fragbox, which has mediocre (at best) ventilation on the CPU side. OCed to 2.7 @ 1.175v and am getting around 50*C idle on the hottest core, and a solid 71*C on the hottest core after hours of Prime95. I'm sure a lot of the AMD guys would crap looking at those temps, but they are 100% within specs.

And yes, lapping will void your warranty. There is no need to lap with the temps that you are running, period.

Could alwats lap your HSF if you wanted too.

Or could attach a higher CFM fan thatll lower temps a bit more, TBH I wouldn't have it that high what JJBlanche says is true but it can still reduce lifespan and out of 3400mhz and 3000mhz you likely wont notice any difference at all.

Thats just me though, mine runs at 55 at max possible temp.

CPUs from the factory are rated to run anywhere from 10 to 15 years at stock settings. We all know no one runs their procs that long. Even the most vicious over-clock/over-volt (say, 3.6 GHz/1.5v on a Q6600) would only take about 20% to 30% off the life of the CPU. That's still 7 years...5 if you want to be a real pessimist. To date, I've never run a performance oriented CPU for more than 3-4 years.
