You'd have to stretch the meaning, or have a huge multiple heatload to call the air that comes out a rad
WARM , it's quite cold from my rad. you'd be better off utilising that airflow for the case(mosfets and capacitors,HD's,CD~ROM's,ect) and adding a 120mm blowhole up top to keep it shifting...
If you put a duct(please do!) you can make 2 120mm's fit nicely, but have the fans
apart from the rad, not bolted straight onto it, have the duct between rad and fan. I'd rather have a cuple of 120's@7Volt than multiple 80's or 92's(which I have now

)...
