--- Quote from: Fozzy The Bear on April 10, 2008, 09:49:42 am ---The other alternative is one of those smart power strips, that powers one socket constantly and when you turn the device on that is connected to that socket, the other three sockets power up. So connect the X-box or Sky Box to the primary socket and the fan to one of the others..... every time you turn on the X-Box the fan will then start up. --- End quote --- Like this idea, know about the power strip but hadn't really considered this an option for some reason - in fact just replied to a thread about this! What I could use then is a powerstrip and a fan from quietpc.com that would run all the time the xbox is on. I have a couple of 230v AC fan's and they are noisy. The pc ones are of course all <= 12v. Anyone know what I would need to buy from maplins to get from 230v (UK voltage) to 12VDc? Is it a case of finding a plug adaptor with the right voltage and splicing the end, adding some female discnnects to the fan? |

Is this just some static thing or is the thermo shutting off not shutting off instantly, so there is some residual power while it is shutting off if you see what i mean? --- End quote --- To answer your question, the noise is most likely the electrical noise created when the thermostats switch opens. The arc sends out radio waves too, which could be why the speaker amps are picking it up. You can try to move the thermostat to a different position. You can also try powering the fan from a different power outlet. Or you may have to install a capacitor/resistor across the thermostat to quench the noise. |

It shouldnt have to be very big if you are just powering the one 12 volt fan. Probably a 500 ma one would do good. Just cut the plug off the end, wire it to your 12 v fan, plug it in, if it works great, if it doesnt, reverse the leads to the fan. I agree with Fozzy, this is most likely the best way to go. |

Heres one, but you will need to wire a automobile cigarette lighter type plug on your fan.. http://www.amazon.co.uk/POWER-INVERTER-AC-240V-12V/dp/B000S0XNME/ref=pd_sbs_ce_title_1/202-1419878-2770267 |
