CPU Temp monitor

hey guys, i’m trying to find a utility that will let me monitor the temp of my cpu. i’ve heard that you need to find a program that works with your motherboard. i’m not entirely sure where to find my motherboard model or manufacturer in the device manager, but i’ve googled my laptop model number and couldn’t find anything. any help would be appreciated.

i have a Dell Studio 1735

intel core 2 duo @ 2.00Ghz

4 gigs of ram

ATI mobility radeon hd 3650
