Can you have too much air flow through a radiator?

post #1 of 12
Thread Starter 
I have my PA120.3 in push/pull with 6x 60cfm fans, Now it's my understanding that the PA series we built for lower RPM/CFM fans?

Would I benefit from a lower fan speed?

no. the more air you move through the thing, the cooler it will make the fins, which will make your computer colder.

a cold computer is a happy computer.

well, fans do generate heat..
but you're good for now. when you have 12 200cfm fans on that, THEN you'll feel it.

Higher airflow is always better but you will reach diminishing returns as you turn up the airflow.

you cant have too much but you will get to a point of diminishing returns where adding fans/airflow does nothing to help temps

The more fins the rad has requires a higher RPM fan for better cooling.

Like bitemarks says, law of diminishing returns.

I have one powerful fan on my heatsink and when I add another identical fan the temps don't drop at all.

There's no such thing as too much, but there's a point when you'll stop seeing any improvements
