CPU Heat sink Question

Last response: in CPUs

So this might be a stupid question, but i have this heat sink:
Thermaltake Frio Dual 120mm Fan CPU Cooler ( )

The heatsink comes with 2 fans, one of them on already for exhaust blowing air out.

If I was to install the second fan, would it be used as an exhaust fan too? Or is to used as in intake and facing the opposite direction.

The first fan should be an intake, pulling air in and blowing it across the radiator. The second fan should be exhaust, pulling air and heat out of the radiator. The main thing is the both go the same direction and either point out the back of the case or up (if the mounting system and your case allows it).

Generally those type of heat sinks are meant to be set up as "push-pull", one fan should be "pulling away" from the heatsink towards your rear/top exhaust, and the other fan "pushing" in the same direction as the other fan. So <---F HS <---F . F = Fan HS = Heat Sink, with them pointing towards your case exhaust.
