Thanks Mike. Well, now I'm upset. See, I'm mostly keen on the AOpen because I can get one half-price (maybe i'll tell you where after I decide!) which probably means a saving of Â£40 ($60) over the Asus board I'd buy otherwise. Anyway, I'm sure I'd read someone on the SPCR Forum say it COULD do Cool'n'Quiet, so I went and did a bit of searching again, and sure enough:

(near the bottom)
So I delved further and found the following on the AOpen tech support forum (this is the best from a couple of posts about the same issue):
Topic: Cool'n'Quiet with AK89max works !!!!!!!!!!!!!!!!!
Posted to MOTHERBOARDS on 7/21/2004 3:26:08 PM by Helmut Auer
After a long time my AK89max now agrees to throttle the CPU when no load is there
When searching through the forum I found a thread with the statement that C'n'Q will work with Bios 1.06h and 1.06m but only with one RAM Module.
But I never got this running.
Now I just tried the new 1.07c Bios and for the first time I found a BIOS option for Cool'n'Quiet !
Its hidden in the Advanced Chipset section in the RAM settings menu !
After I set this to Auto ( disabled is the default ), my linux system is now able to throttle the CPU to 800 Mhz and sometimes even the CPU fan stops !!!!
P.S: This setting is also available in older BIOS versions, but I didn't see it there !
I also read in another thread (which I now can't find) that only certain revisions of the AK89 will do Cool'n'Quiet - which leaves me wondering whether I should take the plunge, play around with some different versions of the BIOS and hope for the best. How hard did you try to get Cool'n'Quiet working Mike? I saw you mentioned in one thread that you'd like to have it, so if you as the guru definitely can't then I wouldn't rate my chances!
