Where do you get FanXpert? I did a google search and I only found one source to download it from and when I downloaded my anti-virus software was going crazy and deletes it immediately due to harmful program. So I am skeptical taking my chances with that one website. ASUS doesn't have it on their website either, just only information about it.
Is it only in BIOS or is this a windows based software?
Unfortunately,fan Xpert mis reads some cheaper coolers and will only run them at a minimum of 90%,whilst just leaving it off the fan will tick over normally. Shame really.
I know what you mean. I have stock corsair SP and AF fans that came with my 450D and fan Xpert won't allow my fans below 700 rpm or 35%. But it's fine, since 700rpm is pretty low anyways. It seems like PWM works far better with fan xpert since my PWM fans are at lower RPMs.
I just hope fan xpert works with corsair AF and SP 120 LED fans i'm planning on getting soon.
