will a swifty cool a peltier?

[Subzer0]

an idea of a peltier on my mobo with a 1.4 chip came into my head but i feel that considering the 1.4 does produce alot of heat im not sure a swiftech mcx-462 can do that good of a job. what do you guys think?

[Diggrr]

Nope.
Even the mighty 462 would need to be 2.5 times bigger to do that. (with a hella big fan)
A peltier not only cools the cpu by moving it's heat away, it makes plenty of it's own heat. It'd be like cooling 2 1.4's.

Donny paycheck is doing it with a palomino, but that's a cooler running chip.

If you want a pelt, you've got to bite the mullet :eek: and get a watercooling system.

ok thanks for the input dudes!!!

using one with duron 800@950 with vcore of 1.7 and 120 watt peltier temps are 30c and using water 27c.
needs a cold plate that is bolted to get the right clamping pressure and could have insulated the socket better then I'm sure the temps would get lower.
even still 8- 10 degree drop makes it worth while. I don't know if it would keep up with a 1.4 or not

It defintely won't cool a Tbird as those 1.4tbird run extremely hot.

You shouldn't go peltier without water..

I need to be at 172W or 220W TECs (or dual 120s) minimum for a t-bird. Anything else just won't cut it.

Thats nuts.

You must need a very powerful cooling rig and do a condensation check before powering up the thing for its first run.

How are the temperature below 0?

[ButcherUK]

My tbird (1533, 2V) puts out 103W of heat. On a 120W TEC that's going to mean the pelts gains a few degrees at best, more likely none at all as the increased heat from the pelt would negate any gains.
For 172 or up you need a high end water cooling system. Depending on the clocking and volting a 220 or dual 172s or 220s can usually see you below 0. For instance if you run dual 172s and keep the hotside to 50C (no mean feat given the 600W or so of heat off that) then a 100W cpu would be around freezing, certainly down into the condensation area. If I can get the money together I'm planning on trying a dual 220W setup, that's about 850W of heat off the pelts! Yes I am crazy :D

hard to find power supply for 172w or 220w you will need 18v for optimal perforance a 156w tec would be much easier to power.
have power 25a supply 12- 15v a 156@12v would cool better than a 172w@15v
although you could use 2 172w peltiers much easier to fit than 156w (40mm vs. 48mm).

[ButcherUK]

220W are 15.1V, 23.8A pelts, 48mm substrate though.

who selling 220w tec?

The highest I've seen it 172W here (http://www.tedist.com/specs/index.html) (drift 0.8). It's US$35.

They say to use a waterblock or a "suitable air cooler". I've never seen a suitable aircooler for this size tec.
*edit-except maybe the 8" x 6" industrial heatsink from www.melcor.com

[Christoph]

Anything like that in the US?

[Diggrr]

Not that google can find. Make friends with one of the fine mates from the UK.:D

Wow I want a 220 now. I have everything I need to add a peltier to my system accept a power supply for it. Who makes an inexpensice power supply that will give 15v at 25a?

That's not an easy thing...a surplus outlet might have one, but otherwise I'd look in a ham radio catalog or maybe on ebay. I have a 35 amp 6-24vdc regulated PS (for ham radios, not anything in my computer) that I got from www.hamradio.com (ham radio outlet) but it cost about $130 new and it's linear, not switching, so it's heavy as a boat anchor.

Diggrr beat me to it! LOL I was salivating at the chance to say "YAY I DID IT" when I saw the title of this thread!

I want to know where to get a 220 module too....not for computer use, I have a high power diode laser that I want to do some temperature/max power experiments with.

[ButcherUK]

For UK supply www.wsplc.com does a 13.8V, 23A cont. supply for £70. weights just 1.8Kg, which is damn light. Other than that a SEC1223 should do it.
For ordering from the UK it's £1 = $1.5 roughly and you'll be paying about £15 shipping.

[res0r9lm]

radio shack has 25amp regulated can be ajusted 12-15 for a round $100
