Right now I am running an older water setup. Origional Swiftech Apogee, Switech 355 pump, crappy reservoiur, 1 120mm & 2 120mm radiators. It's on a single cpu loop at the moment.

I have been looking into getting a TEC, but I have not been able to find a lot of information about them. I read all of the links in the sticky (http://www.overclock.net/peltiers-te...l-threads.html)

What is a good TEC? What power supply? and as far as motherboard insulation goes it basically voids the warranty I assume?

What am I looking at as far as price goes for a good setup?

Do I re-use my waterblock or is it better to get an all in one?

The biggest TEC you can run with a standard CPU block is a 50x50mm. You can get a 320W on eBay that isn't to bad I've used them before.

You can either make a PSU to power it from an old ATX PSU with at least 25 amps on the 12 volt rail or buy a MeanWell. For the 15 volt 320W I just use a old ATX PSU that I modded, it runs it around 12 volts which is about right for it.

You'll need a 1/4" copper cold-plate. A good heavy duty back-plate will help you to get a good mount, I make mine out of 3/8" HDPE.

You'll need some good fans on your rads to get rid of all the heat, if you have single row rads I doubt they would hold the temp's well enough.

A 320W TEC will do so-so on that E8### chip but thats about it, you'd probably load at 10- 20C or a little higher depending on rad and fans and idle at -10-15C with a good OC on it.

The newer i7's are running hot enough now that I wouldn't even bother putting a 437W pelt on them, if I cant load around 0C I'm not going to spend $20-30 a month on electric for it.

I'm not trying to talk you out of it and if you have good enough rads all you would be out is a couple of dollars for TEC, PSU and cold-plate. But if you would need to buy a lot of extra gear to do it I don't know if I would even bother with it to be honest.

If your just doing it to OC maybe just get a dry ice pot to bench with and WC'ing fro 24/7 use.

If your just doing it to play with thats cool to, there a lot of fun and I enjoy playing with them myself, but with hotter chips they really aren't a very good cooling solution.

i haven't seen 0 load temps with TEC's for a very log time.. i still think it's worth it though.. in the old days you may have gone from 50c load to say 0 but now your going from 70- 90c to 20-30 .. so it's still worth it in my opinion

What do you mean single row rads??
I have some crappy single 120mm and theDanger Den Black Ice GTX Xtreme 240.

Well basically the only thing thats keeping me from running 4.4GHz stable is temps. I can do like 1.386v stable, but I get around 80c (With tranny cooler not danger den rad). I dont know if these are normal temps or what, but it's the only thing keeping me from doing 4.4-4.6GHz all the time.

That's pretty hot for Wc'ing at that v-core. What kind of fans are you using on your rad's? You might just run your two rads in series and see if it helps. I run a big rad and high cfm fans but I can keep a 1.4 v-core at no more then 15C or so Prime load over room ambient.

You'll have a lot higher heat dump with a TEC in your loop, the chips dump plus the TEC's. I use a 480 GTX with 8-115cfm fans on shrouds in a push-pull for my TEC loop.

A cheap but decent TEC rad set-up would be 2 Bonnies in series with some medium cfm Pana on them..Heater Core ...86cfm Pana ..Each Bonnie would perform about like a 320 Swifty with those fans.

um Im not sure what you mean by "bonnie" I run scyth ultra kaze fans 1 3000RPM and 2 2000RPM.
They are in series. Res-Pump-CPU-Rad1-Rad2-Res

The extreme temps where I live dont help either I am sure. It's about 26c in my house (its currently 42c outside)

Maybe I should check my pumps flow or something.

The Bonnie is that heater core I linked you to up there, its out of a 1976 Pontiac Bonniville..

I have high temp's here to that's one reason I went on to TEC.

The Kaze have decent cfm and static pressure so you should be OK with them. Maybe put them on shrouds, that's usually good for a couple of C.How To: Make any Sized shroud in 2 minutes ..And or add a couple more in a push.

Yeah those temp's just seem to high for a WC'ed rig, with a 26C room ambient even 60C load would be hot for the E8### chips at that v-core.

Has it been a while since you cleaned out your rad and blocks? I usually wash my rad fins out at least every 6 months or so to get the dust out and ten clean the inside of it and the blocks with 10% white vinegar and 90% distilled.

Does your pump seem a little weak to you? Maybe try a few block re-mounts, maybe your TIM ios getting old.

I have cleaned them out pretty good. I flushed it like 5 times and ran vinegar and water for about an hour or two each time. The Thermal paste is applied good I have removed it a few times and put it back on. I am starting to think its this pump. Is there a test or something to determine the condition of the pump? Maybe time how long it takes to fill a gallon jug then figure out how many per hour that would come out too.

I have an old Apogee waterblock idk if that has anything to do with it.
I want my case to look pretty also. Thats the only reason I dont have a heater core.

I bucket test for flow with 2-5gallon buckets, mark off the catch bucket in ounces or whatever you want. On the res bucket just silicone a barb into the bottom side of it or the very bottom, the res bucket is connected to your pump. Set them both a little higher then the pump so water wont run through it when the pumps off. Then just fill up the res bucket and run your pump for 15 seconds and see how much is in the catch bucket x that by 4 to get gallons per minute. Prime the pump and have that all goi9ng before you time it of course.

That blocks fine, your only talking a few C between it and the newer ones. Once you get your rig going right you might want to get a more modern block but the Apogee isn't going to make you run 20C+ to hot.

Can you take some pic's of you loop set-up? Maybe I can see something in those.

Well I basically had nothing to measure the amount of water my pump moves other than a milk jug so I timed how long it took to fill it to the top and it took 45-48 seconds I ran the test twice (would have done more if I had help) it was so close on time I figured it was consistent.
I don't know if my math is right (it's late so if im wrong it's b/c i am asleep) Thats like 90 gallon's per hour???

I will take those pics tomorrow after work. I have it all taken apart atm.
