I recently bought a computer for gaming and it seems a bit noisy, unplugged all the fans in my case and plugged in one at a time to isolate the noise and it seems to be coming from the fan on the Cooler Master 212 Plus. I installed it properly with the anti-vibration pads between the fan and the heatsink so it's not an installation problem. When it's running at 800rpm the noise is noticeable but not bad, but when it throttles up to 2000rpm it's like a jet engine.
My question is whether I can replace the fan on the heatsink and reduce the noise but not endanger the proper cooling of my processor. Or even crazier.. would it be possible to remove the fan altogether and use passive cooling.
I would prefer fan(1) since it's much quieter and has a lower rpm but it's airflow is a bit low and somewhat of a concern. Fan(2) has much better airflow but it has a higher RPM and more than twice as loud. Would fan(1) be enough to keep the CPU cool and if not will fan(2) be significantly quieter than the Cooler Master fan?
