Hey everyone,
Do any of you know if it is possible to connect up a small 240v extraction fan to the power outlet of a Yamaha DSPAX 830 se amplifier.
The inside of my A.V cabinet is getting extremely hot with the doors left closed,just wondered if a small,quiet fan would be possible to connect up via some sort of temp probe.
I know some of you will say leave the doors open but I like the tidy look,(lol)
Sorry if this thread is in the wrong place ROLFW but couldn't think where else to put it.
Thanks all.:)

LOl, this section is fine for the question sat novice. :)

You'd probably be better off with a couple of 12v fans and drill some holes in the bottom of the cabinet to pull in the cooler air. You could then use a simple temerature switch inside the cabinet to control the operation.

Nice one rolf,I thought about the 240v outlet option because it is switched via the main on/off button on the amp,thus reducing the already overcrowded a.c extension/trailling lead.Plus the fan only cuts in when amp is on.
Do you know of any small extractors that have a built in adjustable temp probe as a one stop solution.?
Had a quick look at maplins but not really what i'm looking for.:)

Not really to up on that type of equipment, but the after market cooling fans for computers are pretty much ideal for the purpose and all you would need would be a 12v power supply with a floating mains lead. Temperature regulation will probably be preferable at all times when the unit is on, so a thermostat may be unnecessary.

Some of these fans should work well for that.

This 8cm one has a built in heat sensor http://www.ebuyer.com/customer/prod...2hvd19wcm9kdWN0X292ZXJ2aWV3&product_uid=56770

As does this 12cm one
http://www.ebuyer.com/customer/prod...2hvd19wcm9kdWN0X292ZXJ2aWV3&product_uid=54151

As rolf says an intake at the bottom and extractor at the top should keep the air moving nicely, if you have room the 12cm spin slower (so are quieter) but as they are larger move the same amount of air.

Just to finish the whole thing off, and stop wires and fingers getting into the fans, some fan guards might be a good idea also
http://www.ebuyer.com/customer/prod...2hvd19wcm9kdWN0X292ZXJ2aWV3&product_uid=43058 for 80mm

or for 120mm
http://www.ebuyer.com/customer/prod...2hvd19wcm9kdWN0X292ZXJ2aWV3&product_uid=63161

and if you are really looking for neatness then a filter on the intake fan will help stop you blowing dust into your cabinet, but that is probably a bit excessive.

Hi,

The firm Papst has a few 230 volt ac fans that have buildt in temperature control, Conrad here sold them.
Might be worth investigating if Conrad ( on the web too ) has them still m8.

Cheers,

Cor.
