Cooling fans: suck or blow

Ok, you get the idea.
Thinking of fitting a cooling fan to the rear end of Schmidt Newtonian OTA, should I get the fan to blow into the rear of the cell holder or extract air from it?
Sucking air from the cell and push it out seems sensible, but will I get more efficient cooling by blowing air onto the cell assembly?
Thanks
