TEC's and PSU's.. Need help!

d5k · 07-24-2001, 02:03 PM

Real quick question.. I'm planning on building a new rig and was wondering how many watts should I get the TEC at? I'm planning on purchasing an Enermax PSU, 650 W with 20A at 12V. Most likely, I'll also have 2 CDROM drives and 2 HD's running an Athlon 1.333.

Also, what about the 451 W PSU? That one has 15A at 12V. Any suggestions would be MUCH appreciated!

(also, I plan to water cool the TEC...)

TEC wattage really depends on what you are going to cool with it, then you can see if the PSU will drive it.

I've suggested this a few times.

get a maze2.2, get 2 156watt pelts, run 1@12V and the other @5V.

that 650W will be able to handle both pelts that way + your system.

Let us know what temps you get.

I am quite a newbie when it comes to pelts, so I have a few questions:

1) peltiers come with bare wires, so what do i do? (silly question.. I am dumb =D )

2) how would I run the two pelts on different volts?

Thanks for any help!

1) grab a spare connector and wire the pelts to it (or buy a connector at radioshack)

2) to run @12V, wire to the yellow and black wires, to run @5V, wire to the red and black wires.

I was looking into a Danger Den kit which includes a 1250 Eheim pump (I think), a Cooling Cube, and the Maze-2 water block. Now.. how would I fit two TECs?

And, how is the kit itself?

resago · 07-26-2001, 04:36 PM

you would have to get the maze 2.2

resago · 07-26-2001, 05:35 PM

just came from dangerdens site, the maze2.2 won't fit 2 48mm (156watt) pelts.
too bad.

you could get 2 80 watt and get slightly better than a single 156.

or you could get 2 172 watt pelts but you'd need 24V.

Do you have some old AT power supplies around... if not you can get some for mighty cheap.. Procooling has a great article on how to wire up power suppplies in series and in parallel. The 120Watt 24V peltiers are only 8 amps. Two 300W AT supplies running in series should be able to supply that. ie Two 12V lines at 8 amps in series make 24V at 8amps.... HOWEVER. like the article says.. do not attempt to do this if you're not sure what you are doing.... get a knowledgable friend to help you out.

Hm... two 80 W peltiers sound interesting. But, I have little to no knowledge of wiring, so I'd like to stay away from having to use two PSU's. I guess it sort of boils down to this question:

With a 650 W Enermax with 20A at 12V, can I even consider a TEC and water cooling or should I just use water cooling by itself and buy myself a 431 W PSU (far cheaper!)?

You guys have been a great help! Thanks!
