Default Thermalright Ultra-120 not so great?

Hey all, I just went to Anitec recently and bought an Ultra 120, I finally went and installed it just a moment ago. When I turned on my computer, the temps from BIOS was 29C, so I thought, not bad. I then left my computer on, and when I came back, the idle temp was 40C! I used Orthos to stress my CPU, and the temps went up to 60C.. Even my stock cooler was better.. I tried remounting, but the temps were still the same.

Any Ideas?

You might have put too much thermel paste on the CPU ?? I have one of these on a overclocke E6850 @ 3.81Ghz and my temps never go over 55 full load...

I don't think so. I used the AS5 instructions on how to apply TIM on a dual core, but then again, the MX-2 tube opening is bigger than the one on the AS5.. Maybe I did put too much..

I'll remount and come back with some temps soon.

Put a coin (a quarter) between the heatsink and the mounting bracket to increase pressure and tightness...

Wouldn't that make the heatsink too tight then?


Anyways, I remounted the heatsink, and reapplied the TIM. I read online that I should put a grain size splotch in the middle of the CPU, so I did that. My idle temps are now still 40, but load is 50 now. A little improvement, but I am still disappointed..


EDIT: I just tried the coin thing, but now my temps are back to when I had 60 as load..

I'm using the Scythe Slip Stream fan, the 800RPM version. Heres a link: http://www.ncix.com/products/index.php?sku=26746&vpn=SY1225SL12L&manufacture=Sc ythe

Running a fan with a higher RPM will definitely give you some improvements. When I switched to a Noctua NF-P12 from some generic fan with lower RPM there was a noticeable drop in temps. I've also got an overclocked chip (e6750) with a TRUE and it as well never goes over 55C on full load, and that's on a hot day (well hot for Newfoundland anyway...) I think the best way to apply AS5 to a Core 2 Duo is just a thin strip from top to bottom in the middle of the IHS.

I just put a 1200RPM Scythe fan on the HS, and now, I am getting 33-36C idle and 40-48C load.. Quite an improvement.

NOT a good fan for that heatsink. You should be looking for something like a Yate Loon or Noctua P12 1200RPM which should drop your temps by at least 10%.
