Radiator help

post #1 of 7
Thread Starter 
Just bought an H60, And im somewhat poor atm, i want to do push/pull and i have a spare 120mm fan laying around, but its slightly slower than the stock corsair fan that comes with it (55cfm vs ~72 i believe) so i just wanted to know if there is anything wrong running a radiators exhaust fan slightly slower than the intake, or vice versa, any help is appreciated, thanks guys

Ideally they must be the same fan on each side. If you have a slow fan before a faster fan it will just slow down the intake air, if you have a slow fan after a fast fan youll slow the exaust air

Actually, the faster fan will cause the slower fan to speed up due to the difference in pressure which will result in the slower fan being pushed beyond what it is supposed to be running at.

This will result in extra wear on the slower fan and reduced life.

All in all, I would not recommend it.

If you run a fan the moves more air than another fan then the one that moves more will cause the slower fan to speed up beyond its limits causing the slower fan to wear out faster.

Well it was a pretty cheap fan so im not too too worried about killing it if thats all the harm that can be done. But you guys are sure jesus wont come out of the clouds and **** over my temps because im like.. screwing with his airflow or something right? I just wanna be able to OC higher... :/


Edit: in essence, i just want to make sure that adding this fan will help, and not hurt for as long as the fan lives

Yes it will help, you are pushing more air through the radiator which will always help temps.

Go for it
