Coolermaster hyper 212 +

are you trying to use the peltier effect to cool a cpu?

Hello!

No, I would guess that would be impractical?I am using the peltier effect so I can utilize its "cold side" and I need a heat sink
to prevent the cooler from overheating. The cold side is going to be used to create a supersaturated vapor. (I could have
used dry ice, but I chose the peltier cooler so everything stays electronic.)

Since, this is not going to be used in conjunction with a CPU its 4pin connection is hard to use. I was thinking that I could
cut the wire and use one of them to connect to the voltage source. I probably will have to research which of the hour wires
needs to be used.

Thank You in advance,

there have been attempts to use peltiers for cpu cooling

but as you say its a bit impractical

due to--condensation--the amount of power needed for the peltier--and the difficulty cooling the hot side

think there is a heat sink that uses a peltier--but it switches it on and off to stop it getting too hot so

the coolings not that great

would think the 212 fan would be 12v

but as its a 4 pin fan then pwm comes into it

some one will come along who will know how to connect it  

Hello!

So:

Pin 1 - Ground - Black
Pin 2 - 12v - Yellow
Pin 3 - Sense - Green
Pin 4 - Control - Blue

I have a 13.8 V power source (6 amps/8 amps surge).
So would I hook up this to Pin 1 and Pin 2 to get the
fan running?

yes but without a pwm signal, the fan will run at full speed.

I'm not sure what 13.8v will do to the fan designed to run on 12v. Be sure to put a fuse in. 1a should be plenty.

Well, with a little research, I actually found that a 12V (by name) outputs 13.8V.
Here's the link: http://www.eham.net/ehamforum/smf/index.php?topic=79932...
It is from a forum so it is possible that the information's wrong.

It is certainly easier than making a simple voltage divider.  

As for the pwm signal I guess I will have to try it out. I don't know if full speed
will be necessary to disperse the heat in a peltier, but maybe a little more speed
could be fine? (though noisier).

Thanks,
