Typical cost of TEC? - Overclock.net

hurrp · 07-27-09

I already have Watercooling, i want to know the typical cost of cooling my CPU with a peltier or whatever it is called

Since you have a quad, the greater cost in the long run will be your electric bill. You'll need a 437w TEC for a quad, that's gonna run your bill up a noticeable amount.

Well you can't currently buy a TEC water block ... so the answer is as long as a peace of string..

i have an ex demo TEC water block i guess i could sell

Well there are two paths you can take. The water chiller path expensive and must be custom made but thermally and electrically more efficient. Or, direct die. Direct die now suffers because TECs arn't made in a high enough wattage to cool Core i7s and such.

The electricity isn't to bad ..you can turn it down for 24/7 usage then it may be comparable to another graphics card ..

Anyway who cares how much it uses if you want to go sub ambient it's gonna cost you in electricity no matter what you do.

i think the oversized V8's from fstfrddy go for around 200-250... not too sure... ask him for a quote over PM, but it gives you a general figure. also not sure if that includes a cold-plate.

usually a PSU can cost around... 100-120 iirc... not 100% sure but a ballpark figure...

the TEC itself costs 20-40 depending on where you get it, insulation can be scavanged from anything that's packaged in closed-cell foam, add some kneadable eraser/liquid electrical tape and dielectric grease/ vaseline... shouldnt cost too much and you may already have some of it.

I honestly wouldn't bother using a 437W TEC on a quad, not if your looking for low temp's. I can barely keep dual cores with a decent OC at a little above 0C with one at load.

The electric where I'm at runs around $30 a month for 24/7 with a 437W.

Even if you already have WC'ing it would need to be a heavy duty set-up to handle the heat and by the time you buy all the stuff to set one up you could almost get a single stage phase that would give you a lot better temp's and a lot better OC'ing.

If your just wanting to do some suicides or a little benching you can get a DICE/Ln2 pot for around a $100 and get some good runs fairly cheaply, well with dry ice its cheap anyway.

My standard response to Ira-k standard post .. is

Although you may not get to 0 load temps from say 50c like you used too you can get from 80c to 30c ... which is still worth it in my book

I personally think Dice/Ln2 is pointless. sure you can get super low temps and a great overclock but who cares you can't use that overclock. for more than a few minutes

It's fun..

..It's just for suicides of course. But a lot of guys like it for just that reason and just run on a HSF or WC'ing for 24/7.

It really just depends on what he's looking for, going from WC'ing to really good direct die TEC is about like going from a HSF to WC'ing except its a lot more expensive and you have to pay for the electric every month to.

If his WC'ing is already set up well for a big heat load getting a 437W block and a 437W TEC and PSU might make more sense if he only wants to spend $3-400 more on it.

But if he has to redo his WC'ing loop and buy all that I'd just get a single stage phase and load at a -30C or so. It wouldn't cost any-more to buy, the electric bill would be about the same and he could really push his OC then.

I've used them all and TEC is fun but it's really not that good for pushing OC'es.

i kinda have to agree with both of you

suicide runs are pretty fun indeed, but its just not (yet?) worth to me the cost of a pot...
