I ran all tests multiple times, usually because I removed the heatsinks to check the TIM spread. All units where cycled for approx. 24 hours before running tests. The posted results are the second of two identical consecutive tests. The minor changes in some systems I attribute to the clamping design and/or the thermal capacity of the heatsink system.
The three Dells all have dual heat-pipe heatsinks for the GPU, two fans, one for the CPU heatsink and one GPU heatsink pipe, one for the other GPU heatsink pipe.
The IBM has a common GPU/CPU heat-pipe heatsink and one fan.
Any questions, I will try and answer.

There is always something waiting at the end of the road, if you're not willing to see what it is, you probably shouldn't be out there in the first place.

Life's Journey is not to arrive safely at the grave in a well preserved body, but rather to skid in sideways totally worn-out shouting 'Woo Hoo! What a ride!
