Abit an8 ultra - cpu fan speed prob

[ja3h]

i just got an artic freezer pro for my athlon and i read on the instructions that if i set the low temp to 65 it will cause the fan to spin slower (i want it to be quiet!)

So i disabled abit eq beeping and shut down etc. and set the target low temp to 60 and high to 70. I save in the bios and restart, the pc is a lot more quiet but it refuses to boot! I've disabled all the relevant settings (temp monitoring and control and fan speed monitoring) so i can't think what it is wrong.

I've also disabled that all in bios and tried it using the uguru software in windows and if i choose a mode like quiet it will freeze and reboot or just freeze :|

it is the latest bios revision... any ideas? I'm thinking of putting a zalman fan mate on it and putting it on the medium setting but i would prefer the original method!

you are somewhat overclocked according to your sig - do you also have Cool'n'Quiet enabled?

Did you also adjust the CPUFan voltage down (there's a bug that it doesn't like under ~9.5V iirc)?

I find it better to set up the user presets in OcGuru in Windows & use those e.g. the factory Quiet setting uses 2.6V Vdimm & my RAM won't run at that ...

thanks for the reply mate. When i was doing it i was at stock speeds. And i disabled cool n quiet. ok yeh i set it to 8v for the fan i think. I'll try it later with 9.5!

I believe that some people have disabled the rpm check on the CPUFan header (otherwise it will shut down) & then used 1 of the OTES fan headers to supply less voltage to the CPUFan.

Hi BUFF, how do I disable CPUFan header rpm check? Do I disable it in the bios or abit EQ?
