I just wanted to let you know I had the exact same problem on a ASUS k8v se deluxe mobo with Q-Fan Control enabled in Bios, as Ticket 1722. Fedora Core 2 i386 kernel 2.6.9-1.11_FC2 and Fedora Core 3 X86_64 kernel 2.6.9-1.724_FC3 As soon as all the modprobes were completed modprobe i2c-viapro modprobe i2c-isa modprobe lm75 modprobe eeprom modprobe w83627hf /usr/bin/sensors -s # recommended the CPU fan went to maximum RPM. w83697hf-isa-0290 Adapter: ISA adapter VCore: +1.57 V (min = +1.71 V, max = +1.89 V) +3.3V: +3.33 V (min = +3.14 V, max = +3.47 V) +5V: +5.21 V (min = +4.76 V, max = +5.24 V) +12V: +11.55 V (min = +10.82 V, max = +13.19 V) -12V: +1.04 V (min = -13.18 V, max = -10.80 V) -5V: +5.10 V (min = -5.25 V, max = -4.75 V) V5SB: +5.62 V (min = +4.76 V, max = +5.24 V) VBat: +0.40 V (min = +2.40 V, max = +3.60 V) fan1: 0 RPM (min = -1 RPM, div = 4) fan2: 5000 RPM (min = 3341 RPM, div = 2) temp1: +43?C (high = +4?C, hyst = +56?C) sensor = thermistor ALARM temp2: +50.0?C (high = +80?C, hyst = +75?C) sensor = thermistor alarms: Chassis intrusion detection ALARM beep_enable: Sound alarm enabled I used: w83626hf init=0 as suggested by Khali and it all worked fine and the CPU fan acted as it should do. It also then picked up fan1 speed. Thank you very much for the tip. Cheers Tony. _________________________________________________________________ Click here for the latest chart ringtones: http://ringtones.com.au/ninemsn/control?page=/ninemsn/main.jsp
