I tried this both with automatic control enabled in the BIOS and disabled. And then I tried again to echo 0 into pwm[1-4] with either mode. Nothing :( > You need to set there manual mode first.

Seems the one that comes with my distro (Ubuntu 7.10) was a bit outdated. I also have files called pwm?_mode, which are not explained in the docs. I'm guessing these set either DC or pulse control of the fan output. I tried modifying the values here too (either 0 or 1 was accepted). Didn't help either :-/ Anything else I could try? Thanks. Casper Btw. with ASUS Q-Fan enabled the fans do spin down, so at least the Q-Fan thing is working. But manual control not..
