@ axipher, I will do the same as you have done. Instead of buying two new fan I'll now only buy one instead as in order to use 212+ with dual fans I already have a 90mm fan that is a very high rpm (4600rpm) fan. I think I will be able to mount this 90mm fan on 212+ without a problem. Also, as there will be now two different rpm fans i.e. 2000rpm (one that comes with 212+) and one which I have (4500rpm, but I will be running it at around 3000rpm coz it is very loud at 4500rpm). So, how should I mount these two fans i.e. high rpm fan, blowing air into fins or pulling out from fins to rear fan? Lets, say if I mount this high rpm fan pulling air towards rear exhaust fan, then as this is spinning higher than rear fan (2000rpm), is there a possibility that the rear one will be having interruption in its rotation due to heavy air flow coming to it but it cannot handle that heavy air flow due to its slow speed.
What do you think??? What should I do?
