Richard Jones' Log: Shuttle HTPC woes, redux
The Shuttle PC I've had for a while now has recently taken another turn for the worse. Some readers may remember that a while back one of the fan controllers decided to stop working. To "fix" that I switched to the second fan controller. Now that one has stopped working too. Sometimes it gets stuck on "mid" speed (which is pretty noisy) and sometimes it just doesn't go at all.
In desperation, I pulled the case off and plugged the fan back into the primary fan controller. That worked (even controlling fan speed) for about a day until it cut off again. Switching back to the second controller has made it usable for another week (but stuck at the noisy "mid" speed).
I've now upgraded the BIOS to the latest version (even though the BIOS change notes mention nothing about fan control). No change.
I'm pretty annoyed at all this. Shuttles are not a cheap system. The rest of the components in the system are working fine - it's just that I can't keep it cool, even by forcing the fan to stay at a high speed.
I've done some poking around on the net and this isn't an isolated experience.
I'll definitely actively recommend against a Shuttle system to anyone I know in the future.
Next up I'm going to investigate hard-wiring in a potentiometer off of the power supply to manually control the fan speed.
Update: I've posted my "solution".
