Could these temps be real? (pic)

This is a screenshot of CoreTemp (which claims to use sensors directly on the diode) reading the core temps on my AMD64 5000+BE with a Zalman CNPS9500A + ArcticSilver5).

These are my idle temps....

Wishful thinking? Or could that be real?

I ran Prime95 for 10 hours to find the top temperature to reach 20C.

UPDATE: My BIOS reports 27c idle.
 
there wouldnt, by chance, be a stiff breeze blowing through the house would there? Georgia Dome style;)
 
I checked my BIOS and it reports 27c, so that's probably the right temp...

yea, those chips run hot, so no def not right.

From what I remember reading, one of the strengths of it being a 65nm chip is that it does NOT run hot. you may be referring to the 6400+BE, which uses the older architecture.
 
even with the best air cooling you're not going to be far under ambient temps, it's just no possible. But if your rooms ambient temp is near 50F then this could be possible. the 27C puts the temp around 80F so that's probably a lot more realistic.

Thanks for clearing that up for me!

You can't be a fraction of a degree under the ambient temperature; ambient is the absolute minimum. Heat will only transfer from a hotter to a colder substance unless you put in energy to force it the other way, so when the computer is at the same temperature as the room then no more heat can be transferred. I believe this would apply even for water cooling, just that the transfer would happen more efficiently? The only way it's going to get below ambient is with refrigeration/Peltier cooling.
 
Mithent you're correct in that the best cooling that passes the energy into the air in the best case scenario is only going to be ambient. I guess I was being too general in knowing that sensors are rarely dead on and because of external circumstances that are beyond control. You may set your thermostat to get a reading of 70F and your computer temps may read 69F, things like that because of placement of vents, breezes, accuracy of thermostat.
I was just giving a general answer that sometimes your sensors will read lower however it'll never be drasticly lower than ambient.
You actually can drop below ambient with water cooling but not for long, you do need an external souce of cold. for instance wiping your radiator with alcohol continuously over a couple of minutes will lower the temps slightly, although around a dergree or so and not worth it in any circumstance. Adding ice can also drop the temps but it will always stabilize to ambient.
