Help with my HSF!!! Or isn't my CPU flat.

[jonny13]

I just got a Thermaltake Dragon 478 last week and it performs like sh*t. I get temps that are 3 degrees warmer under load than the Intel HSF. After taking it off and replacing it with the Intel one again, I noticed that it looked like only the corners of the CPU are actually touching the heatsink. Is this a bad CPU or a bad heatsink. Since the Intel HSF performs better, it makes me think the surface of the CPU is not flat. Can I lap the CPU heatspreader or is that not a good idea? Or should I just RMA it back to newegg and get a new one? Here is a pic of the bottom of the HSF.

Check each with a straight-edge, probably the Thermaltake. It looks like it may take a little more than lapping, doable but maybe not worth the trouble. A thermal pad may work, though people aren't crazy about them.

wow contradicting information. according to the boys at hitechmods, the D478 is better than the stock HSF. check out their review.

At least it doesn't have a pressed piece of copper in the base like the V6cu or the V7. Anyhow I highly doubt your CPU doesn't have a flat surface - try to find another D478 and try it out....

I would think it's the heatsink that isn't flat. Go with a sunflower.
