I'm about to get a WC system for my PC along with a few upgrades, and now I'm thinking maybe I might as well go all the way and get a TEC (phase change would be too loud and impractical for me). But I've got a few questions.

1 - What kind of TEC would I need (size, power, and voltage) to cool an OC'd QX9650? I figure with the amount of power its gonna use and the cost to run it, it should at least get to temps below freezing to make it worth using.

2 - What kind of insulation would I need to get?

i think phase would be more practical honestly. Tecs are garbage for everyday use.

Why do you say that?

Because you can set up a single stage phase for what a good TEC rig costs..They work fine for a every day use though, I run them all the time..

For a quad I would use a 437W TEC, it might work OK with a 45nm quad and its lower v-core..On the older quads I don't think I would bother TEC'ing one..

You have to look around your socket area and make sure you have room for a 62x62mm TEC and cold plate..I had to use a 320W 50x50mm on this E7200 for that reason, instead of my 437W..

With this 320W I idle at -30 to -25C and load up Prime after an hour or so between 4-8C, thats with a 1.42 v-core..My rig is kind of tricked out though..

I would WC for a while before trying to set up a TEC loop, lots of things can go wrong starting both at once..

fstfrddy here makes a TEC block that will fit the 437 and Arctic Web does to...Get a 480 rad and plan on using higher cfm fans..

Thanks for the links, much appreciated

And of course I wouldn't do both at the same time, I'd at least have to test to make sure everything is leak proof and none of the parts I'm ordering are DOA. And there's always the risk of the peltier burning out the CPU without the water cooling working properly. So that goes without saying. And as far as cost goes, I'm really not worried too much since, like I said, a phase change would just be way too impractical for me as it would be separate from the case.

Just one last thing - would 400W be enough, or would that extra 37W make all the difference? Only reason I ask is because there are some good deals on ebay for 400W models (under $20), and they are 50mmx50mm so are more likely to fit.


Edit: Do they make full custom waterblocks or just the cold plates?

The reason why i said go with phase is most of the time you will need a second power supply to run the tec and most people cant two power supplys and all the water cooling gear in one case. So if you have to have a second enclosure you might as well have a phase change system and get better temps. I didn't look at your specs though (like the jackass that i am) and it appears your tagan 800w should be fine. You have to be careful with ebay tecs btw. I know a lot of them are inferior in quality. I am sure other people will be able to help you out with that.

Manyak

Ok then I guess I'll look for a different TEC.

But yeah, even with two power supplies I'd still be able to fit everything into one case. I still have my CM Stacker T01!

Ok, I see which 437W TEC you were talking about ira-k.

Also, apparently those ebay ones really are completely mis-advertised, they say 400W but their Qmax = 177W, Imax = 20A, and Vmax=15.4V. There's nothing there that even suggests 400W.

So I guess that covers everything.

That TEC is really just a 270/320W...They kind of inflate the figures, all TEC's are rated at 25C and 50C hot side, for our use we go by the 25C figure..Look in the under-volting charts at the 320W TEC, thats it that you linked, its what I'm using now..

Here is the 437W...437W Qmax Peltier

Yeah for the 437W you need a special block since they are bigger, either a Arctic Web or one of fstfrddy's if you can talk him into making you one..I use a Stinger fstfrddy made for me..

I use this PSU on my 437..SE-6000-24, Mean Well SE-600-24 ..I can get mine down to 21volts,some you might not be able to, its just luck of the draw, you don't want to run a TEC at full voltage, they are just to ineffiecient...And the 437W would put out so much heat at 24vdc it wouldn't even be funny..I try to run my TEC at twice the heat dump of the CPU, or a little more..

EDIT: I didn't even see you last post...You already figured it out.....

lol yeah after actually going through them and reading their specs I realized they were crap.

Anyway, yeah I already PMd fstfrddy about it to see if he can make me one.

And I already ordered two GTX480 rads, so I'm pretty sure that will cover the crazy amount of heat that's going to be put out.

So...I think that's it. I guess well see what happens in a few weeks
