CPU too hot, seeking advice.

My new X2 4600+ idles around 51C. I applied the correct amount of AS5 using an XP-90, with the fan pointing down blowing air onto the cpu. I have a praetorian with the correct settings for the fans: 2 intake in front, top exhaust and rear exhaust. I'm not overclocking anything, I'm just wondering why this new chip is running so damn hot? Any advice?
 
Everest Ultimate ED and I checked the bios hardware monitor for temps too. Not real sure how accurate those are.
 
assuming you have the direction of your intake and exhaust fans correct then i suppose it isn't an airflow issue.

how are your ambient temps?
 
Have you tried reseating the heatsink? If not, in the process ensure that it's making proper contact with the processor.

Also what motherboard are you using?
 
I suspect the temp readings are bogus.
At over 50C, touching the heatsink will feel very warm.
If it doesnt feel very warm, you need to use an external sensor to get a better idea of the temp.

if it really is that warm, its likely the heatsink paste or cooler are not setup correctly.
Only way to tell is take it apart and check how the heatsink paste has spread and how thin it is. If theres thick lumps/patches of it anywhere on the CPU die, the heatsink isnt sitting properly or isnt clamped tight enough.

If using AS5 paste, you may be applying it too thickly?
 
I'm experiencing something similar, according to the bios my opteron's are idling in the low 50's, but the hsf's (ultra 90's) feel just as cool as the air around 'em.
 
reinstall hsf correctly. and update ur bios, some asus boards have higher temps reported by older bios. upon upgrade temps reported dropped 5-7C degrees.
 
yeah, I reread that later and thought the same, oops.

I should have said, if the heatsink doesnt feel very warm then there is likely to be a bad heatsink contact but you need to make sure that the temp really is around 50C by using an external temp sensor as close to the CPU core as possible.

you could also use CoreTemp or the new Speedfan beta. that will read the cpu core temperature from an internal sensor rather than mobo sensors.
 
He doesnt know if the temp readings are correct from any of the sensors.
I agree, the wrong sensor could be being read, but equally possible, the reported temps can be way out.
I had an Abit AN7 motherboard which reported CPU temps on the correct sensor between 36C idle and 43C load.
The real temps were around 27C idle and 52C load.

Using an external sensor its worth finding out the approx CPU temp on idle and load then try a few sensor programs out and see if any of the temps look the same/similar.
Its worth noting down the names of the sensors and what the reported temps are on idle and load for later comparison if you cant get an external sensor.

The final readings from a dodgy sensor can be useful even when very wrong as long as you know what the temps given really mean once tested with an external sensor :)
