What to do next

[DiverDave]

I'm O/C conservatively and in small steps. Over Thanksgiving weekend in the US I took my first shot, taking my E6400 to 2.66GHz using wusy's guide. System specs are below. I have no plans to go crazy and I remain a bit concerned about temperatures which I might have to go and investigate further. TAT shows max temps of ~60-62C under load with the existing stepup.

What should my next steps be and how much of a concern are the temps?

Specs
E6400@2.66Ghz
Gigabyte DS3
2G XMS Corsair 667 PC5400 Ram at 4-4-4-12
Arctic Freeze 7 cooler
AS5
Centurian 5 Case (1 80mm fan intake, 1 120mm fan exhaust)

Idle temps are about 45ish after running at load for a while prior to checking, they are about 40 if I check right after turning the PC on. This is about 5C higher than they were before O/Cing.

I haven't gone into the bios to see what the temps are. I assume that EasyTune PC Health data would be the same. If that is correct they are about 10C lower.

I'll check when I get home.

There seems to be some descrepency about what temps are correct. There was a discussion in another thread.

TAT and coretemp run about 10 degrees higher than speedfan, bios and easytune for me, and it seems you as well. If you believe TAT, as mpilch said, you're a little on the warm side. TAT and core temp show me around 60 at full load. Easytune and speedfan hit a max of 47 on full load, 33-35 idle. I'm hoping EasyTune is correct.

How does the CoreTemp/Speedfan/Easy Tune compare to the temps shown in BIOS?

I did that, watch BIOS for awhile, then went into Windows and turned on all of the above apps to monitor.............but for the life of me, I can't remember right now which ones matched 😳

Going from my experience and what I've read from others here, coretemp and TAT both seem to run about 10 degrees warmer than the others. As to which one is coreect? Who knows. Bios, easytune and speedfan all read the same, so I'm inclined to go with those. 3 against 2.

If I go with Speedfan/EasyCool (and maybe the bios but I still haven't checked) I'm looking at 32C at idle with a max of 42 or so.

With TAT I'm looking at 45 with a max of 65. I didn't notice this before but not only is there a delta of ~10C between the two but the delta from idle to load is also doubled.

If I go with Speedfan I feel more comfortable but based on your comment regarding deltas it seems I should go with TAT...and that means I'm running really hot

Going by your build, I can see no reason why your temps would reach 65. Expecially with that mild OC. Personally, I'm going with speedfan since it matches the bios. If you can't trust the bios to be correct, then there's a problem.

Ya........and I get CoreTemp showing temps about 10C higher than EasyTune, etc. So worst case scenario, my CPU is 58C @100% load. My guess is it's lower than that, but even if not I'm still good. No need to push my CPU to the extreme......I'm happy with a 60% overclock 😉

Good point. If the bios dictates when to throttle back the chip if there was a mismatch it would likely result in customer returns due to overtemping CPU's

BTW I also notice that the temps with using TAT to set the CPU to 100% load vs using something like Prime95 and examining the task manager are different by about 4-6C (on TAT, it's about 1-2C on Speedfan)

IF...and I haven't checked yet so it's still a IF, one of the pins for the cooler came loose how much would the temperature change? Would you expect to see much higher temps than this?

I'm reasonably certain that the cooler was connected properly but I did it with the MB already installed (the reason is another long story). So I couldn't look underneath the MB and confirm that the pins were properly installed. They seemed to be and it seemed solid but there is alway a chance that it is not. But I have no idea how much the temp would increase under such a situation.
