Fan runs constantly with kernel 3.2.0-36 and higher

Bug description:
Using ubuntu 12.04. Recently, I have started to notice that the fan on
my laptop runs CONSTANTLY. This has never been an issue for me before
(been using 12.04 since release). Investigating the issue, I have
discovered that when running kernel 3.2.0-35 or lower, the fan runs
only intermittently if at all. But when running 3.2.0-36 or 3.2.0-37
(the latest release today), the fan runs constantly, even for minimal
computing tasks.
It appears that a power-regression has been introduced into the
kernel. Any chance this is fixable so that 12.04 can run fan-free
again?
