My desktop runs Natty, got the regular update upgrading the kernel to
38-10 and appears to be running several degrees cooler. Did not observe
this in detail, as I was far more concerned about my netbook which is
running 5 C hotter than usual.

My netbook will be upgraded ASAP, the rest of you might want to try
upgrading to a current kernel version and see if you still have the problem.

YMMV and good luck.
