System Fan Has Failed!

[Snee]

Shorting the pins doesn't usually work, the pins are linked to a counter which signals an alarm if it doesn't get a minimum number of inputs per second, but that may vary on some motherboards.

It depends on what whatever checks for the fan is after, as you say, I think that may vary.

If it simply checks that something is connected, leaving the counting bit to whatever utility they intend you to use, then woot.

If it also checks that the fan is running, then bleh.


EDit: also, since there's no system health in that bios, I was thinking it might be doing the former.

No. It checks the speed of the fan. As soon as it drops below a predetermined speed you get the alarm or alert.

Bugger.

No go then.

I wouldn't try and make my own counter, that's more work and possibly money than just buying and connecting a fan.
