CPU temp and fan speed monitor for windows? Air i7

[SpiffyChee]

I know this is a mac forum, but I feel that with the air i7 it is important to monitor the cpu temp and fan speed. In lion I've been using iStat Menus 3, but I cannot find for the life of me any good piece of software for windows.

Can anyone point me in the right direction?

SpeedFan.
Haven't tried it in a Boot Camp partition, though.

SpeedFan was good years ago.

HWMonitor is the top program now.
