Hi,
The motherboard from an HP ML110 G7 server has hard-coded some sort of fan RPM requirement and if it doesn't meet it, it reports an error then powers off. I don't know and can't find what the minimum RPM is.
The original 80mm fan (Delta PFB0812GHE) is rated at 6100 RPM, which at full speed is way too noisy for a SOHO environment. I tried Noctua's NF-F12 industrial 3000 RPM fan and even this isn't 'good' enough, even without PWM wire connected to force it to spin at full speed. It's crazy because the original case has this 80mm fan at the front, a 92mm fan on the CPU and 92mm fan at the rear. New case has 3x 5-in-3 drive caddies which all have fans, so overall provides much better cooling even without the 80mm fan attached!
I've transplanted the guts of this server in to a new (much bigger) case which only has 120mm mounting holes.
Anyone know a fan with high enough speed that this board might accept?
Thanks
