CPU fan error with 120mm NEXUS - help?
I've got a new ASUS mobo with a 120mm NEXUS connected to the CPU 3pin fan header. The mobo reports a CPU fan error on BIOS POST with the NEXUS but not with the stock AMD HS fan. Both fans actually spin normally and speed varies with load etc., NO difference in functionality. Why the error with the NEXUS. The mobo instalation instructions mention: "If and AMD stock HS/fan is not used, an appropriate 3rd party HS with a thermally controlled fan MUST be used". What's a thermally controlled fan? Is the Nexus thermally controlled? Is this why I get the error?
Thanks
Thanks

My Asus K8S-MX mobos have a fixed 1800RPM CPU fan speed threshold that cannot be changed, only set to ignore. The RPM is then reported as zero, which causes SpeedFan to provide erroneous readings on thermal diodes, including the one in the SiS chipset and the one on the CPU die.
I wasted a day chasing an overheating CPU that wasn't overheating at all; I had turned off the CPU fan sensor and got hit with the SpeedFan bug.
I now accept the "hit F1, ESC" as part of the bootup sequence.

My Asus board does the same thing with a Yate Loon at anything below 1000rpm. I switched to a Globe fan and the board reads the rpm down to 700 rpms, and starts without hitting F1.
I am tricking the board now by attaching a quiet 60mm fan to the CPU header.....it runs about 1200rpms at 5V. The board starts ok with this setup.
