I have 2 IBM 8090 machines. Small Form Factor.
Both are P4 3.0 GHz HT processors.
On startup, both immediately show at 58C while idle.
While browsing the web, they reach 66C.
Used for folding on a team. While folding, temps jump to 78C and hold steady.
All temps are shown by SpeedFan and HWMonitor.
Have removed all old thermal paste and applied new thin coat of Arctic Silver 5. No change.
Due to the tri-fold configuration of the machines and the size, opening the case is not an option.
Hard drive rests above HSF (copper) with inlet fan blowing through fins of HSF.
Has anybody got any ideas on how to bring these temps down?
Already have an ice tray sitting in front of them and a fan blowing towards them.

Are you having issues with the SFF computers freezing or crashing? If not, don't worry about the temps... SFF computers as well as most laptops run hot, compaired to desktop systems

No freezing or crashing,Runs fine. Also run Throttle Watch and have never seen any indication of the CPU being throttled back.
Just concerned because the processorfinder site shows that 68C-69C was the thermal limit. Been going past that.

As I said, forget about the temps. They are not that bad for an SFF
