My Pentium D 930 (With OEM Heatsink) seems very hot. it's about 65C reported by BIOS at idle. But motherboard temperature is just about 42C.
DO i need to buy another heatsink ?

If it's that hot, the heatsink your using is not seated right in the first place. Once you mount a 775 heatsink, I always tug on it to ensure the feet are properly seated to the board. Otherwise, you'll continue to have heat problems. Another way to solve it is use a cooler from zalman or the like, where you actually screw a plate to the board which IMO, is much better.
