hi ya..
yes... thermal compound/grease seem to work better than
the thermal tape ...
make sure too that there s about 0.5"-1" of clear air space for the
heatsink fan...
I'd also want to see if water-cooled copper reservoirs would
be a better cooling method than huge heatsinks
We have to get all that to fit into our 1U chassis
other variable affecting cpu temperature...
- load of the cpu...at the time of the measurements
- copper will always be better than aluminnum
- painting it balck seems to make some difference
- whether the block of aluminnum/copper was
cut or extruded to make the heatsink fins/towers
also is very important...
- airflow and ambient temperature also affects the cpu temp
have fun
