Q6600 voltage and heat issue - seated incorrectly?

MoRT489 · 11 May 2009 at 13:16

OK so i've tried reseating my Tuniq Tower a few times and I'm not happy with the temps:

Idle at stock voltage 1.2v 32ºC
Load (orthos) at stock voltage 1.2v 61ºC

Idle at OC voltage 1.55v 47ºC
Load (orthos) at OC voltage 1.55v (1.48 CPUz) 81ºC+

Obviously cant keep it on load for long or it would fry!! This cant be right. Tried AS5 and now MX2 (yes i cleaned inbetween :rolleyes:

)

Could this be anything other than an incredibly concave/convex TT? Worth lapping the cooler? Unsure about lapping CPU due to resale value :confused:

What are you using to measure temps?

1.55v is fairly high for a Q6600, so yes those temps sound about right to me. With an IFX-14 and two fans mounted my (fairly poor) Q6600 at 3.5GHz needed 1.45 to 1.5v to run stable and that hit temps approaching 80 degrees C. Dropping it down to 1.35v at 3.2GHz made a lot more sense and reduced the temps a lot.

The idle reading is the same in BIOS and CoreTemp, load just CoreTemp.

There are plenty on here running theirs at high voltage and the 65nm range are reputed to love vcore so i dont think it should be a problem for a cooler of this size. I had my e2160 at 1.55v for testing at 3.4GHz and that never went over 75ºC.

When i ran my E2160 and DS3R the TT never got warm to the touch but does with the Q6600 and P5Q Premium which makes me think it probably does have contact :confused:

It is the incredibly high idle temperature that gets me and after a failed overclock at 4GHz 1.55v no load testing (i.e. crash before windows) BIOS reports temp at 71ºC :eek:

47oc seems ok for 1.55v on air to me .

It seems shocking to me coming from E2160 at 34-36ºC on the same cooler, do the extra 2 cores really make that much difference!!

The q6600's do tend to chuck out a lot of heat, particularly under load. Mine was hitting 81c on 2 cores at 3.8ghz, 1.50625 vcore. Lapped both the cpu and my TRUE black and got the temps down to 68-68-62-62.

Is this the system in your sig? Remembering there are four cores not 2.

Sig needs an update running:

Q6600 G0
P5Q Preimum
OCZ Gold PC8500 1066
HX620
8800GTS 512MB

Previously had the Q6600 at 3.5GHz in DS3R as in sig. Didnt try the E2180 in the P5Q.

That's a phenominal drop in temps :eek:
