Q6600 + TT120

[TomL]

Hi, just stuck together a new a Q6600 and a Tuniq Tower 120 on a Asus P5K Premium DDR2 motherboard. The Q6600 is running hot with idle temperatures of around 45c.

What I'm more concerned about is the fact the Tuniq Tower is heating up considerably, and I'm wondering whether this has something to do with the IHS on the CPU being concave/uneven. I know it's mounted properly, as that is pretty difficult to do wrong.

Before when I was using a E6300 it would reach temperatures of 50c under load when at 2.8GHz, the TT120 never got anywhere near as hot as it does now.

Anyone have any thoughts on this?

C1E is turned off in BIOS, I think that's Speedstep. The case is a P182 with the two standard fans drawing air out away from the TT120. You can actually feel the heat on the top fan spoiler after a few minutes use, it's worrying .

Should I lap it?

Cores 0 and 1 seem to be 1c higher usually:

I used a thin line down the centre as demonstrated here.

Okay I think I've sorted it haha.

You just need to make sure you have an even application of thermal interface material between the heat spreader and heat sink. A line down the middle, then turn the heat sink clock wise and counter-clock wise once or twice and it should be fine. If not you may need to look into lapping the heat spreader and bottom of the heat sink.

Somewhat unrelated to my op, what should I use to stress test this Q6600? If I run two instances of Orthos at priority 9 Vista freezes instantly, now I'm not sure whether that means my system is unstable or it's a compatibility issue with the software.

Any idea why the web master hasn't put the latest version of Prime95 up on his site?

I've left Prime95 running this morning. Got my Tuniq Tower and the two Antec P182 fans running at maximum with the windows open in my room, radiator turned off.

When running 1.4v through the Q6600 all cores will pivot around 60c, my room is freezing though so imagine what it'll get like in the summer. The noise takes some getting used to too. It idles at around 38c if I remember correctly.

Got my FSB set to 450, strap to 333, multiplier on 8, with this my PC2-8500 RAM is actually running underclocked. These Corsair sticks seem pretty fail though, four sticks of 1GB, timings of 5-5-5-15-4-42-6-3-3 and I don't think they'll go any lower... Can anyone recommend a good set of PC2-8500 memory? Are two sticks of 2GB better for overclocking?

I'm getting a score of 13.9k in 3DMark06, this might go higher if I increase the PCIE frequency - shall I overclock my 8800GTS 512?

Last night I noticed my memory score in Vista went up to 5.9, I dunno what I've done in my BIOS but the system seems silky smooth where as before it was bluescreening and the like - I am pretty confused by that.

Can a mod can move this to the overclocking forum please? Thanks
