Hey Guys,

I'm pretty new to overclocking and i'm away to start later today. I've been checking out the core temps ( coretemp 0.99.4 ) and the idle temps seem a little bit strange to me....

core 0 - 31
core 1 - 31
core 2 - 25
core 3 - 24

Temps are in idle in vista with nothing overclocked yet, just stock settings.

There's a pretty big differnce in them. Not sure if the program i'm using isn't any good or if perhaps I should resit the heatsink and redo thermal paste.

I'm running a Q6600 on a P5Q Pro mother board with 8gig of OCZ Gold 8500 at 1066. This is all sitting in an Antec 902 with 4 fans but another 120mm case fan is on it's way today for the side of the case. I have an Artic 7 freezer heatsink with Artic 5 thermal paste.

So anyone know whats up with the temps at all or if you think I should resit heatsink ect ?

Any help would be much appreciated :)

Thanks,

Kev
 
Check that all the legs of the heatsink are correctly fitted. Those standard push pin fittings are really easy to get wrong.
 
Thanks

I'm gonna refit the heatsink when i'm installing the new case fan then. I see that you are running the same mobo and cpu as me :) I also notice a v nice overclock. Are you running your setup on air too and what kind of temps are you getting out of interest ?
 
The assumption of course is that the IHS is flat, but more often it isn't.

You can see from this picture the problem I had with a Q6600:

You can improve the contact by "lapping" the IHS, which make the surface as flat as it can be possible.

Yes, running a Thermalright Ultra 120 Extreme (TRUE) with a Noctua NF-P12 Vortex 120mm fan on it. It's in my new Silverstone Fortress case.

The temps after an hour of Prime95 Small FFTs are 69,69,65,65. Given that it is damn near silent, the temps are great. The cores are normally within 1-2c of each other, so I think the large 180mm fan at the top of my case is making 2 cores cooler. Not that cooler cores is a bad thing of course ;)
 
One side of my heatsink for a Q6600 unclipped itself the other day. Fortunately my BIOS shut the PC off before any damage was done.

I really hate those push pin things. I have bolt through kit on the way.
 
I have pretty much the same setup as you OC'd to 3.1ghz and idle (after an hour or so) temps are identical to yours. After an hour of Prime95 / OCCT they max out at 50-50-48-48.
 
TBH I dont think a 7 degree spread is too bad - im on my second Q6600 and they both had a similar spread of temps

Some chip s have better spreads as some are better at overclocking / Vid etc - i wouldn't worry about that spread

See how they fare when you've OCd the chip :)
 
Well iv'e resat cpu and heatsink and re-applied artic 5. Now i'm getting

28
28
24
22

So not quite sure what the crack is. I'm thinking the heatsink needs lapped but don't have stuff to do that. Case fan never arrived either. Never buy anything from ****** there are terrible. I think i'll just stick to overclockers from now on. I'll just turn up Artic 902 fans and see what happens :) Wish me luck. Thanks again guys.
 
I've got 32,35,28,35. That's the closest I've got them. that's OC'd to 3.2ghz, As long as all cores stay under 70 under linpack I'm happy.
 
Mine are currently 33, 33, 27, 27. I've got a lapped CPU and Heat sink with a thin layer of MX-2. I think it just depends on your chip, nothing can really be done to make them closer to one and other.

I had a similar issue when first starting with an Intel® Core™2 system and found that for general use/non lapped chip that the blob'n'go TIM application method worked better than a Credit Card spread, the latter is great for lapped CPU's but not recommended for bog standard Curly-Whirl Intel® IHS! :p

[edit]@kev, the standard Intel® LGA775 push-pin method for mounting the HSF is as much to blame for substandard cooling and uneven temps, ditch the push-pins and use a Thermalright LGA775 Bolt-Thru-Kit :cool:
