KEEP intake and exhaust fans on high mode?

post #1 of 4
Thread Starter 
Should I leave the intake and exhaust fans on high mode? These are the 140mm Noctua's, they are quiet so I could keep them on high using the fan controller. Or should i keep it on Medium? Keeping it on high reduce the life span?

Run them full speed and replace them when they fail. They have 150,000 hour MTBF. That's like 17 years, at full speed.

It all depends on temperatures with in the case it's self. Can you run the fans at low RPM without over heating? If you're temperatures are good, I would keep it like that, saves time screwing around with fan controllers and will be a bit more set and forget.

Noctua fans come with a 6 year warranty so they should be able to run at full speed for 6+ year without failing, if they fail within 6 years Noctua will replace it anyway.

Run your case fans so they speed up and slow down with your CPU and GPU fans. That way your case airflow matches the demands of our coolers airflow. wink.gif

Can be done using PWM fans with the PWM signal from CPU fan socket and GPU fan socket.
