I am putting together a system from mostly spare parts with an Abit AW8 and P4 D 3.0 GHZ.
I've tried 3 different heat sinks, and the system reports ~53 degrees C at idle.
I've tried Intel reference coolers from a Q9550 and E6850, as well as a Zalman CNPS 7000 Cu.
I've verified the voltage is stock and there is no over clocking.
Whats your room temperature and what do the other cpu read at idle?
My Pentium 4 is running about that temp in idle due to moving from the north to the south. Thats also with an underclock/voltage. from 2.8 to 2.6 GHz and 1.38v to 1.28v. Used to be about idle 45c when i was in ohio on stock settings.
Maybe you should try a little bit of undervolting as sometime stock setting can be a little on the high side.
CPU is Pentium D 930 rev B1
Core Voltage is 1.250
I've checked the temp in the BIOS and with Abit's Guru program. It seems the Abit mobo uses a chip that Speedfan doesn't recognize or I'd use that.
Thermal compound was cheap Radio Shack stuff and Zalman's stuff.
As I write this the temp is 48 degrees C with ambiant being 26.6 degrees C.
I've tried with and without the case closed with no noticeable difference in temp. If I stress the CPU and leave the temp monitoring/shutdown on it will shut the system down as the CPU read over 80 degrees C.
And you think that would work better than the Zalman mounting using the 775 adaptor (using 'cause the sink was for 939) on the Zalman?
It has 4 posts securing the adapter to the mobo, and then the sink mounts to it in 2 spots.
