Hi,
I'm going to prefix this by saying this server is used for home NAS purposes and is out of warranty so I don't "care" about HPE support.
I needed more disk slots than this server provides so I have transplanted the internals into a much bigger case (11x 5.25" drive bays with 3x 5-in-3 hot-swap caddies) and added 2 HPE H240 HBAs to connect them all. So far, so good... except the fans.
This server comes with a 92mm rear fan and an 80mm front fan. At least the 80mm one gets WAY too noisy for a home environment plus my replacement case only has mounting holes for 120mm fans. So I tried with Noctua's Industrial 3000RPM 4-pin PWM fan but I get a flashing red light and:
1611-Fan 3 Failure
Fan Solution Not Sufficient
Even though the Noctua has more CFM; 109.8 vs 86.44. I even tried disconnecting the PWM wire so the fan spins at full all the time with no luck, so it seems HP are forcing a minimum RPM on power-on to determine a 'sufficient cooling solution', whch is totally illogical because air flow > RPM!!
So bascially, what 120mm 4-pin PWM fans exist that aren't jet engine noisy and won't stop a ML110 board from booting. Do any of HPE's other non-enterprise servers come with 120mm fans that i could use?
Thanks.
