There was HW-monitor screenshot above already. HW Monitor displays some pretty weird sensors there though. CPU C and CPU D?
If we look at the Macs Fan Control numbers they seem to be fine.
I'd even say the memory temps are exceptionally low, but now I wonder if we can trust HW-monitor here.
Normally those FB-DIMMs get quite hot, even without stressing them they tend to rise immediately after boot. With original heatsinks (big black ones) installed they are lower, but almost all the upgrade modules have smaller heatsink installed, and memory temps do rise to 70-75 C° easily. Just checked that from my 3,1 which just sits idle there now, DIMMs are over 70C°.

^^ Thanks for the info. I didn't know about that Krytox thing when I upgraded my Mac Pro 1,1 to 5355. All went just fine though, I was carefull and my mac was cold enough.

Ok, those readings are from my 1,1, sorry.
Checked the 3,1 DIMM temps, they seem to be at 60-65 C° ballpark, significantly less than with my 1,1. The DIMM's are all of the same make and size at both machines.
