Hi John,

In most of the recent fans I've worked with, you keep swinging/pulling the
levers after they release, and they push the fan off the chip. Once the
levers release, there should be some slop, allowing you to twist a little
bit. I know that wax stuff they pass off as a thermal pad can solidify a
bit, so you may have to work it some.

If all else fails, you may have to break down and completely remove the
board from the case to work it out. Sometimes VERY CAREFULLY prying the fan
with a thick plastic paint scraper can get it up. Watch out for an
capacitors or transistors on the board. You don't want to bend/break any of
these off.

Whenever I get a new fan and CPU, I always scrape off the crap that comes on
the fan using a razor blade and then coat both the CPU and the fan with
Arctic Silver. Others will have their favorite substances I'm sure, but that
one has always worked great for me.

Good luck!

Have you tried removing the heatsink from the cpu right after it heats up?
That might soften the thermal pad under the heatsink enough to allow you to
remove it. If you can find any wooden popsickle sticks you might be able to
get it under the edge of the heatsink and gently twist while pulling up on
it. As Kyle has suggested you may have to remove the motherboard from the
case in order to get a better angle underneath the heatsink.
