I need to regulate the 24v in Bitza down to 12 for some cooling fans what's the best way to do this?

Putting 2 the same fans in series is the most easy way to do it.

As mario say's either 2 fans in series, or just put a resistor on. Those Jaycar SSR's are the cheapest I ever found - although fragile they don't seem alot different to the £80 ones we got from RS years back.

Good find Chris!

That's a good point Mario but I've really only a need for one fan, worth bearing in mind though.

How big a fan do you need? I have a brand new 24v fan for my victors which I don't need (seem to run fine without them) if you'd prefer to run it off battery voltage.

If you have the weight left, a second fan probably is cheaper than any solution involving step-down.

But, what are the stats of the fan? Size, powerconsumption and such

[PJ-27]

Currently plan on using a PC fan, which is perhaps a bit too big (let alone 2). Their use it cooling ESCs so your Victor ones could be perfect!

build your own, thats what i do in laser to regulate the voltage.
a quick search on the internet will find you all the parts and pop down to maplin and they should have all the components. dead easy to assemble and a lot cheaper then buying ready built circuits.

I'll try and get the dimensions for the fan tomorrow and you can see if it will fit.

Cheers Dave!

That's true Ben, but for £1.50 it would be cheaper to buy one. Maybe if I wanted a project!
