CPU fan
Problem
The current CPU fan is making too much noise. Can I replace it with a more silent one?

It's a socket A (462) processor.

Wanted to buy a Arctic Cooling Copper Silent III at the local computer shop for just € 11,- but they weren't sold anymore. Bought a ThermalTake TR2-M3 SE instead.

Again: sensors-detect. One line was added to /etc/sysconfig/sensors.
Was:
# Generated by sensors-detect on Thu Dec 29 11:44:59 2005 MODULE_0=i2c-nforce2 MODULE_1=asb100 MODULE_2=eeprom
Is:
# Generated by sensors-detect on Sun Jan 29 11:12:09 2006 MODULE_0=i2c-nforce2 MODULE_1=w83l785ts
Error messages are caused by line /usr/bin/sensors -s in /etc/modprobe.conf.local.
If I manually do a modprobe i2c-nforce I get the same error message. So I think the command sensors shouldn't be in modprobe.conf.local. I think this line is to check sensors at boot time. Removed it. Reboot...
Errors in modprobe.conf.local reported in /var/log/messages. Commented all lines. Reboot...
No more error messages, but very limited output from sensors.
Run sensors-detect again. /etc/sysconfig/lm_sensors now contains:
# Generated by sensors-detect on Sun Jan 29 13:07:29 2006 MODULE_0=i2c-nforce2 MODULE_1=asb100
Reboot... Now sensors gives nice long output again. So MODULE_1=asb100 seems essential. But the entire modprobe.conf.local is commented...
How can I increase the CPU temperature to test sensors readings?
Found package cpuburn.
What is the maximum CPU temperature?
Found answer at The Heatsink Guide - All about PC cooling. Maximum temperature for my AMD XP 2000+ is 90°C.
With cpuburn running, this is the sensors output:

alarms:
Strange enough, it's the M/B Temp which is rising, not the CPU Temp?
Killed burnK7. Within 10 minutes the M/B Temp dropped to 36°C.
Tried the same on motherboard MS-6340 Micro-ATX with AMD Athlon 800 MHz processor, but apparently no sensors are available since I don't receive any temperature readings by sensors. Replaced the CPU fan anyway; a CoolerMaster CM12V 001006DA with a ThermalTake TR2-M3 SE.
I don't hear a difference! What did I replace? It looks like a CoolerMaster DP5-6I11A. Page says 33 dBA. With just 21 dBA for the ThermalTake I feel okay, but am a bit disappointed I can still hear my PC very well.
Found this review of 65 Socket A Coolers Benchmarking, 2002-2003.
And here's another review SocketA Coolers Roundup. Q1`2004.
Found the SpireCoolers website and the FalconRock II in particular. I can buy this one for EUR 8,95 against EUR 12,50 for the ThermalTake TR2-M3 SE.
