Does the Fan have an auto-off or power save feature?
My rig is in the garage. I wear over ear, noice cancelling headphones, so the fan noise has never been an issue for me while using it. If I do not cut power to my rig when not in use, I can hear the fan, but it has not caused me to want to swap the fan unit out because of it.
I have had for some time an issue with the fan level of noise and have replaced the fan with a Noctua NF-A6x25 FLX.
When comparing the original NMB 2410ML-04W-B40-B00 , the noctua is 19.3 dB(A) and the NMB is 33.5 dB(A)
My wheel is well out of warranty so I am happy to make the change noting the slightly less air flow of 30 m/3/h compared to 36 m/3/h for the NMB.
The Fan came with a 4 to 3 adapter that I could use for the 2 pin connector needed. Fan is pulling air into the power box for cooling.
Silence is golden.
