I would like to use this to run a 12VDC case fan from a 36VDC power source. Will this work? Can I use 12 guage wire with it and will it get hot?

Dear Dale, what is the current rating of the fan? the converter can supply 3A maximum. Beware that you cannot exceed the input voltage (40V). 36 VDC is fine if the source doesn't generate spikes above 40V. A 12 gauge wire is massive, much more than you need for the 3A this converter can supply. Again, I have no idea if it is enough for your fan. Regards, Jorge

The fan is wired for 120v. I don't think it will work, but check the manual.

Try this link: http://wdc.custhelp.com/app/answers/detail/search/1/a_id/1378/#legacy This supply is rated 3 amps, or 36 watts, so i would think so.

It would with an DC to AC invertor. (Or rigging your own 12v to 5v setup as some have suggested) I use a TripLite 12v DC to 120v AC invertor in my truck when I need 120. Fans can be a bit noisy on many invertors. They have to stay cool.

it can run from as low as 5v (at least 1amp but 1.5amp is better). 9v works fine. 12v is what is listed but since it works at 5v, 12v seems a bit too high to me (extra volts are burned off as heat; never a good idea). I suggest using a good strong 5v dc psu.

I had the same problem at the time determining the maximum current but I think most fans should be ok. I used it for a fairly large fan so I'm guessing most is good for most 15 amp circuits .

most systems at 12 volt use 10 amps or less of power. Therefore, 16 to 18 guage wire should work just fine.

Sorry, I'm using fan controller. I don't recall how many amps the MB header will handle, but that might be an issue for some if using just one header for all. Check out this thread, it may help. GL! :) http://forums.evga.com/tm.aspx?m=2012030

It depends, of course, on the power requirements of the fan and the available sunlight. This unit will provide about 0.18 amps of current flow at 12 volts with a reasonable amount of sunlight during the day. For the application you described, it might be best to hook this unit directly to your fan, bypassing the battery. In this manner, there would be zero chance of running down your battery -- at night the fan won't run and on really heavily overcast days it will run at reduced speed or not at all; which would not be a problem since solar heating would not be an issue.

Maybe. Find out if the regulator will overheat with a 12V input. Probably better to use a 5V supply.

This is a 12V. Fan, you cold apply 12v. directly (Ground and +12V.) and it will work at it's maximum speed (google "pc fan connector" to find out) The connector is: |Ground - +12v - Speed sensor - Speed control| However this is intended as a computer fan, i will not recommended it for any other use.

These fans are 12/24 DC, so you will need an AC-to-DC transformer between them and the AC outlet. The good news about this, however, is that the AC current draw will be VERY low.

The unit specs are wrong on the website. The spec sheet on the controller it self calls for 12 volts ac for the power input. But it will run on 12 volts DC. It's just a relay that turns on and off when a certain temp is reached. So a standard 12v fan should work just fine.

I have a set of 10" fans on my 36 chev. They both draw about 12 amps each. So a single is 12 amps dual should aprox, 25 amps .at 14 volts .measured during alternator charging.

You should be fine. Some heat will be generated, but there shouldnt be enough for the need of heatsink, though it never hurt anything to run a little cooler. I would say if you are only dropping from 12v you should be able to go almost to 4amp @ 3.3V before you really need to worry about cooling.

If the controller is made for 12V fans, I don't see why not.. but I can not say for sure.. I don't know how they would fare if the voltage is limited..

I would go to blue sea's tech department and ask them. Since it is for a 48 volt inverter i would assume the amp draw won't be to high and it should be OKbut if there was some kind of short it could quickly overload the system and cause a fire/damage best to check with the manufacture on this one
