I know that it may sound very strange, but could you try to disable automatic fan throttling in BIOS Setup? I have had the same issue and after turning off this option in BIOS it started to work just fine even if temperature is sometimes higher than with automatic fan throttling.
My hw setup:
- D945GCLF2
- 1GB DDR 667Mhz
- PCI Intel Ethernet Pro 100
I use both NICs (onboard and one in PCI slot) 24/7
Kernel version: 2.6.24.5 with boot option pci=noacpi
