A friend has just built a new system Soyo Dragon KT266A board with Athlon XP. I am considering A7V266-E or P4B-T, but have a question about how the BIOS in the Asus boards monitors CPU fan RPM.
What my friend did was put in an 80mm Panaflow quiet fan on the CPU and run it at 7V, with an 80-60 airflow converter on a 60mm heatsink on the XP. At 7V the Panaflow runs at about ~2000 rpm. He has gotten excellent case and die temps, just as good as a noisy 4500 rpm 12V conventional CPU fan. 80mm fans are quieter than 60mm for the same CFM, and running it at half speed makes it yet quieter again.
Both him and I are insterested in (1) stable, (2) reasonably quiet system and lastly (3) solid performance (but not going for the last 5%). I'm not OC'ing at all and am not a serious gamer.
The only issue with this setup is the Soyo Dragon (I think Award-based) thinks that 2000 rpm is a non-working CPU fan, so it shuts down the system (which is why you first have to boot with the fan at full speed and shut off the CPU rpm detection). Now of course, if his fan suddenly stops he'll never know (since you can't hear it anyway
and we'll have fried Athlon XP .... I'm sure you've seen the pictures on the net.
==> Does any one have any experience with the Asus BIOS for A7V266-E or P4B-T whether they will detect slower running CPU fans properly, and/or allow you to set the RPM threshold?
