Cooler master Hyper 212 "Fan Error" On boot

System is an AMD 1090t on a Crosshair IV Formula Motherboard and a Corsair HX 620 PSU. GPU is a Gigabyte R9 270. 2x 4gb of Kingston Hyper X DDR3.

It boots just fine, temps are fine (Individual cores read at 17C, CPU line in HWmonitor tells 28C) and the bios is set to Turbo fan control with a warning at 200 RPM. The fan spins great when out of the case and given a flick, and runs fine in the system, registering 654RPM (But the dang 200MM fan keeps hitting zero, despite running)

Any ideas?

Openhardwaremonitor, pin the fan at 100% then see if anything changed. if the fan isnt PWM it will give errors i think.

A8-7600 {} Gigabyte FM2+ Board {} CX430 {} Corsair Vengeance LP 8gb {} MSI GTX 760 2GB {}

  

Console.WriteLine("C# is aids");

CPU fan reporting at 1800 RPM. All other fans reporting as normal.

The CPU fan is the stock hyper 212 PWM fan.

okay, turn it down to around 30% then let it sit, check temps and if its too high change it higher or lower depending on temps

Don't have that fine of control in the bios. Qfan control and that's basically it. Seeing as the board can't seem to register the 200mm fan when it runs under 300-ish RPM, I'm assuming it's the board being unable to read low RPM and throwing an error on boot or something similar..

have you got a spare 4pin fan header? if you do put it in that and try.

Won't it just throw a CPU fan error without it plugged into the CPU fan header? It doesn't throw the error with the stock AMD fan, but that runs at turbo jet RPM.

disable the CPU fan header.

Sounds like sensor is bit buggy or even broken. You can disable warning from BIOS.

Found something out. The CPU fan doesn't report below 500 RPM to the system, but still reports in a line on hwmonitor. Then, after breaking 500 RPM it pops up another line in HWmonitor that's identical but goes to zero if the fan dips below 500 RPM.

As well, the 200MM fan won't report speeds under 300 RPM, and doesn't show up in HWmonitor until it breaks that threshold, returning to zero RPM reporting if it dips below.
