Stacking fans...

[wingstriker]

Is there a specific way to stack fans? I've got two fans that I have stacked in the front of my case to blow in. The fan closest to the front is weaker and slightly smaller than the other. The other fan, which is the bigger of the two, spins faster than the other and is placed about 2 inches from the first one. Keep in mind that both are blowing air into the case. Is this setup done correctly or should I do something else?

The outside fan should be rotating opposite the direction of the inner fan to maximize airflow. I think you reverse the poles where the wires connect to change the direction but I recommend you check somewhere else before you attempt that.

Ahh, I see what you're saying, that way it creates more of a tunnel for the air. If anybody has information on how to do that without damaging anything let me know. With the fans both blowing in I've cooled my system by 4C already, which means my idle temp is about 44C. I have a copper shim and a SK-6 HSF on the way, so hopefully that will drop it another 4C.
