[Beowulf] liquid cooling for HPC

Hi John,

I got a cluster room which has heatspots of 30 C (as the AC company installed 
the AC simply wrong here).

I need to put in more stuff in that room as that is the only floor space left 
here. Fortunately, we got a chilled water system so that would take care of 
the removal of the excess heat. However, we also got a very cold staircase 
close by and I would like to see the heat dissipating there. At least in the 
winter time it does make more sense to heat up the staircase in a Chemistry 
building instead of a inner court yard. 

Regards

Jörg
