Frozen CPU Pelter Picture - Page 2

Chopes, if you want to get yourself a 24V power supply without breaking the bank, watch this space. Good PSUs at all voltage ranges can be found here.

Meanwell is a decent brand but there are many manufacturers that make good psus too, lamda and astek are a couple that pop into mind...

http://cgi.ebay.com/Power-One-AC-DC-...QQcmdZViewItem - if you feel adventurous.

Btw did you already buy all the parts? If not, you might want to consider investing that money into a phase change setup.

You don't need a 24v PSU for that peltier. Give it half voltage (12v) and you'll be well below ambient. I'm running mine on 12v and not only does the peltier run much more efficiently, but it doesn't produce nearly as mch heat by itself. -25C idle and -10C load is good enough for me.

When running at 12v, it pulls less than 20 amps.

I'm running a Maze4GPU in series with my Arctic Web TEC and as long as you keep the water temp cool you don't have to worry about the GPU. Your vid card produces a small fraction of the heat that the peltier/CPU produces, that your cooling loop won't hardly notice it. As long as you can cool your TEC you can cool your gpu. Just make sure your water loop can handle the TEC first. Plumb your TEC up by itself and run Prime95 to see what kind of water temps you get. With my TEC setup, even at full load on the CPU and GPU, the water barely rises above room temp (can't feel any difference) and the GPU temp stays around 35C when running ATITool's 3D "hairy cube."

Edit: My 6600GT's core is running 700 Mhz with a slight increase in voltage...

The hardest part of using a peltier cooling system is putting the peltier/coldplate/waterblock together. For maximum efficiency, the pelt needs a butt load of pressure on it, squeezing it between the cold plate and the waterblock. If you can get it to fit on the Apogee, go for it. However, I don't know where to get pure copper coldplates, and I also don't know the dimensions of the Apogee. I think the 437w peltier unit is 73mm by 73mm. Your block needs to be bigger than that so you can get the bolts to clamp around the outside of the pelt. If you've already got it designed, show us! I've been considering putting TEC's together to sell in small quantities...

Edit: If the OCZ phase system ever comes out I'd wait for that... You'll end up spending roughly the same amount of money, but phase is quite a bit more efficient than peltiers. Phase systems run around 40% efficiency, while TEC's at peak efficiency (around half voltage, maybe a little lower) are only about 15% to 20% efficient.

I'm waiting for the "Cool Chips" to arrive, then I'll adapt that into my TEC/waterblock and have better-than-phase temps right there. If you're interested: http://www.coolchips.gi/

would it work if you were to make a copper resivor and attach one pelter to each side. Would that cool the water down enough?

my pelt was running on 12v at 0c cpu temp. pelts need lots of insulation to stop condensation, neoprene works well.
i put a pelt between 2 waterblocks, one cooling the hot side the other to cool the water going to the cpu. water temp is about 10c, cpu temp about 19c. the link for it is in my sig.

I peltiers ran better at or around 50% of rates voltage...(more efficiency at least)...so you could try that..and you'd still probably get pretty cold with that big sucker

Sounds like you'd need 2 pumps for that one--but the loop could be nice and tidy since the WB/pelt/WB apparatus could be tucked anywhere convenient--seems like there could be some way to make that look good on an internal install--that extra PSU,2 pumps, etc. would need to be in a server case.

im running 2 loops like this, loop 1: PUMP > VGA BLOCK > RAD > RAD > PUMP. LOOP 2: PUMP > CPU > RES > VGA BLOCK > RES > PUMP. The VGA blocks are the ones either side of the pelt.

I think there was a commercial TEC available that did just that. Good job and welcome to the peltier world!
