I recently built the rig described below in my sig. I feel like I am having some kind of issue with heat, particularly under load.
I first built the system with the paste that comes with the Tuniq 120. I spread it all over the CPU heat spreader like I *thought* I was correct to do -- of course I later discovered that I was wrong. Anyway, with this setup, I was idling @ stock 2.4 ghz around 38c on both cores. This looked a little high to me. Using Intel TAT, I got up to about 54c under load. This seemed REALLY high for load @ stock. I wanted to quickly test the overclocking capabilities of the chip and see if the sucker would post at all at 9x400 before I took the whole rig apart to reapply AS5 (and in the proper way per their diagram). Much to my surprise, using 1.4v for vcore, northbridge, and fsb , it posted without any trouble at all. I ran Intel TAT just for grins and my idle of 52c shot up to 74c under load. I stopped it immediately.
I took the rig apart, took the Tuniq off and cleaned both it and the CPU with rubbing alcohol. I applied AS5 this time around in a straight line down the center of the chip and reattached the heatsink to the CPU and resumed testing.
I thought everything was fine when my idle @ stock went down to 32c idle and 46c load, but an overclocking test at 9x350 put my idles at 40c and TAT load to 66-68c... still too high.
I've read all these reports about how the Tuniq is supposed to do this super job cooling and the results I'm seeing are not in line with that at all. I know I am doing something wrong.
Possibilities:
Tuniq isn't seated properly -- on the EVGA board, the tuniq's fan comes in contact with the northbridge heatsink. This aside, it seems to sit flush in the socket, but maybe it isn't? It seems level but...
Screws too tight / too loose into the backplate? I had to trim some of the foam pad on the backplate so that the stupid little capacitor would sit correctly and that mounted flush on the back. But maybe I have the sink screwed down too tightly?
Have I mounted it in the wrong direction? See the picture here :

Is my case fan system set up all wrong? I have a CM830, so the front fan in the 4x3 unit is intake, and the rear fan in the pic next to the CPU is exhaust. I added a 120mm on the top (exhaust) and I have 3 fans on the door (intake). The 4th can't fit because of the Tuniq. From what I understand, the tuniq's fan is both intake and exhaust together -- would the immediate proximity of the rear fan on the CM830 mess with temps this much? A lot of people have this setup, so I figured I'd have heard something about it.
Do I just have a bum Tuniq? I wouldn't think so, but I found the bottom finish on the copper to be pretty rough. I thought about lapping it, but I think my temp problems are far beyond lapping here...
I've already taken the thing apart once so the next time I do it, I want to make sure I do it right. Any help would be welcomed, particularly from users of this case/HSF setup.
Thanks!
