Hardware monitoring software

This may have already been answered somewhere, in fact that's likely in a place like this, but i ran a search and couldn't find anything, so don't bug me 'bout it

Right... I believe there are certain programs that can monitor the speed of fans/temp of CPU from within Windows, without needing extra hardware like a rheostat?

I've got a modern system so it's got a temp sensor on the mobo, And i can view the temps/fan speed in the BIOS but I'm just wondering where I can get something for use withing windows..

I did a google but only came up with a couple of shareware ones :/ And i'm sure there's better out there...

Thanks ^_^
