does x2 have a problem reporting temp on nforce3?

[cubeless]

i am having a heck of a time getting my 3800x2 to not overheat in my 9nda3j...

i have an hr-01 on it with a 60cfm fan... and i'm not getting much better temps than with the stock aluminum hunk with the stock fan running at warp speed...

at stock it runs up to 55c w/2 prime 95...

i've pulled it off a couple times to be sure that it's stuck on good... using as5... the base of the hsf doesn't seem hot enuf to be reading 55c... it seems like i'm not getting good heat xfer, but the hs is stuck on there as good as it can be...

this is the goofiest time i've ever had trying to cool a cpu...

speedfan sez 1.38 v...

My 3800 X2 Toledo is running 58 degrees on core 0 and 65 degrees on core 1 at 2.5GHz and default voltage running 2 instances of Prime95. I'm using the 4 pipe AMD Opteron heatsink. Idle is 42 degrees on core 0 and 35 degrees on core 1 - opposite of load temps. I'm considering lapping the heatsink and spreader to see if it helps. I'm using Core Temp but Speedfan gives the same reading for core temp on core 1.

I say 55c is not bad at all. I have to run stock, 2.0ghz with a 3200+ HSF, and at load I get 61/55 on core 0 & 1. Lapping would help 5-10C though.

I read from some place (could be AMD site) that Toledo core running from 1.3 to 1.35V. My Epox 9NDA3J MB BIOS set the Toledo core to 1.35 to 1.4V so I go back in the Bios to lower the vcore to -0.01 (you can lower the vcore a bit lower). It definitely helps the temperature issue. Right now, my CPU Cores are around 37-32C idle and with Everest Stability test for 10 minutes, it would never go higher than 57C with ambient temperature at around 28-29C. The test is at 2.4GHz on 3800 X2 Toledo because I couldn't raise it higher than that without my SATA drive goes ape.
