Quick and dirty question... I know an exact answer isn't possible without more precise info, but I'm just after a rough guess.

Assume a WC system with a fairly high coolant flow volume, processors running dual stock AMD CPU's, (No OC, no pelts or radical heating / cooling stuff) There might also be blocks on the hard drives, NB, GPU, etc. I estimate the total heat load to be on the order of 200-250 watts.

Given a good typical airflow through a heater core type rad, IF the intake air is at ambient room temp, what is the temp of the air on the OUTPUT side. IOW, what is the expected Delta-T for air going through a WC rad???

I.E.:

Code:

 
  AIR IN  => => |R| => AIR OUT
  TEMP IS => => |A| => TEMP IS
 75*F / 24*C => |D| => ?? WHAT ??

I can't remember the source, but I think I recall seeing somewhere that it was only a degree or two increase, if that. Is this reccollection correct?

Thanks,
Gooserider
