Replacing fan on existing cooler

[Blackstar_solar]

Hi all,

I've been off the forums for a looooong time so if I'm posting in the wrong place etc please let me know.

I've currently got a COOLER MASTER HYPER 212 EVO CPU COOLER and the fan has got a good deal noisier recently. Having recently replaced a case fan with a
Noctua NF-S12B REDUX 1200RPM 120MM QUIET CASE FAN and being really impressed with how quiet it is I'd like to replace the CPU fan with something similar but the current CPU fan is a 4 pin while the case fan is a 3.

Should I buy the same thing again to replace the CPU fan (3 pin instead of 4 is ok?) or do I need the PWM (this) version or would something else be more appropriate?

If it's relevant, my PC is mostly used for gaming.

Many thanks

May be slightly answering my own question here, but I've noticed that the Hyper 212 is PWM but I've also noticed that it runs up to 1600 RPM. The NF-S12B only runs to 1200 RPM, is that likely to be a problem?
