computer fans wiring
« on: 22 May 2013, 17:18:01 »
I've a couple of computer fans with red, black & white wires going to the pcb. Red & black are obviously 12v & 0v (Yes, I know Mark  ;) )

Out of interest, what's the white one likely to be for?  :-\

Was there a specific reason for asking or just curiosity

Just curious  :y
I have a couple of fans that I want to rig up at the top vent of my caravan's fridge for use in (hopefully hot) French France. I was testing the fans & just wondered what the white wire was for .........  ;) ;)

It wouldn't be difficult to use the signal to feed a monitoring device so that you can be informed when/if one stops working  :y

Makes no difference to me .. fridge vent is inside the awning ! ... What does happen is that if you go out for the day and close up the awning, it gets very hot in there and the "thermal circuit" around the fridge is insufficient to cool the fridge down.

Two solutions ... Andy's of a computor fan just inside the vent area to move the air...

or mine ...

A small 12v car fan, the type designed to suction to the windscreen, but mine is mounted on a small piece of ply with two "lugs" protruding .....  These "lugs" slot into the fridge vent and hold the fan close to, but not touching, the lower vent. Plug that into a 12volt supply and it forces air into the cooling fins of the fridge... result ... nice cold beer on your return .. :)

Advantage is no modification to the 'van wiring at all, and it moves with me every time I change the van .. :)

Sounds like a nice simple idea  :y

We use (as IIRC you do) a seperate 12v/240v beer fridge  :y  :y
