noctua fan

[nadof1]

What do you make of this one of two fans on my NH-U9B has a ring of oil splatters around it.



Looks like a failed seal as its only on one fan and I don't cook chips in my bedroom, any one got any suggestions?

Mm, seems like fun-->

107 cfm... 0,52 amp

Auto Shut down & Restart
Special High-Flow increase 30%CFM (average)
Extra 20% Low Noise (dBA) compare with same Air Flow (CFM)
Performance PWM + High ~ Low Switch 500 ~ 2000RPM (4pin )

What is the benefit of using PWM rather than just adjusting the voltage?
