New Nexus AXP 3200 stops getting to POST

My desktop (well it is under the desk actually!) PC has an AMD Athlon XP 1600+ Socket A 266MHz FSB processor.
I wanted to replace the noisy Coolermaster DP5-6131C Socket A cooler and chose the quiet Nexus AXP 3200 cooler.
However when I now switch on my PC it does not complete POST and loops switching off and on.
I suspect that the rotation of the Nexus fan is not being detected because when I plug the old Coolermaster fan into a second fan connector the PC boots normally. (rotation of Coolermaster fan being detected).
I'm now back to running my PC with the noisy Coolermaster fan.
Please can you let me know:
1. Is the Nexus incompatible with my PC?
2. Is the Nexus wiring different to the Coolermaster?
3. The Coolermaster fan runs at 5400rpm so is the Nexus maximum fan speed of 2400rpm too slow for my PC?

Thanks in advance :):):)

    Plug in the Coolermaster and go into the bios and disable the fan rotation detection switch. I would then lower the temperature warning threshold, but that's just me. I can't give you better instructions as I don't know which MB you've got. It appears that the MB sensors are not, as you said, detecting the new fan. Does it have an RPM sensor lead coming from it as the Coolermaster does? If not, it might just be as easy as getting a new, quieter fan with an RPM lead and replacing the Nexus fan but leaving the new cooler? Just a thought!

    Many thanks for your prompt reply.

    The BIOS current settings are:
    CPU Warning Temperature = 50 dec C / 1220 def F
    Shutdown Temperature = 60 / 140
    CPUFan Warning speed = Disabled
    Shutdown For CPUFan = Enabled
    So where I find the fan rotation detection switch please?
    I need to put my PC specs below my signature in my postings when I find out how.
    My desktop?: SiSoftware Sandra reports: (probably too much info?)

    RPM sensor lead
    Both the Coolermaster and the new Nexus have central yellow leads for the 3 pin connector.

    Does this help please?

    Disable "Shutdown for CPU Fan" and you're good to go.

    OK madmat & flint. I will do.

    Shutdown For CPUFan seemed to me to be rather cryptic in that I didn't find it at all self explanatory.
    Could it mean Shutdown if no fan rotation detected?
    The BIOS default is Disabled.
    Hopefully if I disable that setting, the Shutdown Temperature = 60 / 140 for the processor will protect it.

    That's the plan.
