Pentium 840EE temps, are these too high?

[alizee]

I realize that Smithfield is a really hot core, but I fear I might be doing something wrong.

I just recently purchased for pretty cheap a Pentium D 840 EE, without a heatsink. I put it in a Bad Axe 2 motherboard with my Conroe heatsink (Core 2 e6300), and at stock speeds (3.2GHz, HT on, 800MHz FSB) and auto voltages, the processor is running at ~80C at idle (I'm reading this from the hardware monitor in BIOS). I haven't even begin to test it at load.

I realize this is a really hot running CPU, but I'm used to seeing my overclocked e6300 run less than 50C at load with a Thermalright XP-120. Is the Conroe stock heatsink not good enough to cool Smithfield? OR, are my temps about right? I was looking at getting another heatsink in the near future (January), but do I need to get it now?

Thanks in advance.

A Core 2 Duo heatsink is really not appropriate for use with a Pentium D...

Some spec comparisons:

Intel stock Pentium D heatsink
Fan Spec: 800-2600RPM (est.), 12V, 0.42A
Fan Dim: 25x84x84mm
Heatsink & Fan Dim: 72x88x88mm
Weight: est. 460 grams

Intel stock Core 2 Duo heatink
Fan Spec: 1500PM (est.), 12V, 0.20A
Fan Dim: 25x84x84mm
Heatsink & Fan Dim: 61x90x90mm
Weight: est. 380 grams

Spec sheet says not to exceed 70*C.

Check that you have got a good contact between the CPU and the heatsink.

Failing that you have to get a new heatsink

You can ALMOST boil water with that temp. If CPU/heatsink contact is OK, the HS/F is not cutting it.

Those chips are usally concave in the middle, I have always found putting more thermal paste than normal in the middle lowers temps. Not to sure about using coreduo hsf on it though!

you should get a new heatsink for sure asap if you want to keep that chip for a while. otherwise you may lose it from overheating pretty soon, especially if ur idling @ 81c.
