[Build log]Up coming temptat TEC

[kikicoco1334]

I have always found TEC based cooling very interesting but seems like every time i tried it I don't do good enough of a job and break something http://tpucdn.com/forums/images/smilies/shadedshun.gif
Most of the time it's because didn't have the proper cooling for the hot side.

Now since I've got more hardware on hand I'd really like to try again.


Here is my check list.
3x Swiftech 3x120mm Rad
1x MCP-655 Water pump
1x Water Block for both 1366 and 775 Swiftech GTZ
2x 136.8W Peltier 40mm x 40mm (that's the smallest i can find that's got the most power)
1x Corsair 430W Power supply

I am thinking about putting those 2 TEC peltiers back to back hooking it up in series.
Having the second peltier cooling the first one and having the water block cooling the second peltier.

Now i am just wondering how should i power everything?
I am thinking about having the 24-pin or one of the 6-pin GPU cable to power them.

Really not thinking about modding or changing the physical appearance of the PSU.

One of y'all showed me a pix where the water stuff is in another box, i kinda wanna do that. :thumbsup: just try it out see what's up

[kikicoco1334]

Here is a pix of what the idea is gonna be

don't put sandwich plate TEC,

use them single, dual stage tec is not good on direct die cooling, only for small things like led's and lasers.

Use single TEC more power, 136w is not enough for cpu.

you need something that can cool down the cpu, and a cpu gives overclocked like say 250w,
so you need to cool down that.

Use a minimum of 226w TEC or 260w 50x 50 or 40x40mm.

And cool that down with good watercooling.

Look here in dutch from me :

Chiller's Custom TEC on air (http://abforum.be/showthread.php?t=11702)

chiller's custom TEC (http://abforum.be/showthread.php?t=11703)

and offcourse Hybrid TEC cooling, where tec is cooling down the liquid as i use now in my rig Level 10

[kikicoco1334]

Holy balls bro! that thing looks amazing!

wish i asked you this before ordering those damn things...

you sir have a PM coming your way :D

[HybridChiller]

i thought it would be info you can use in my old buildlogs.

[kikicoco1334]

thanks mate, that really helped a lot

[kikicoco1334]

ok it's been 2+ week the damn stuff finally got here, and had my buddy come over with his power supply and here are some pix :good:

I'd turn the 430W on first that only powers the TEC and 2x 120mm fans I'd normally hook up my temp gauge but for now there is too much stuff on the table

pics of the block?

Temps under load ?

[kikicoco1334]

block? this is water cooled for now, i am working on the thing metal between the cpu and the tec.
i monna use Al for testing right now cuz Cu is a little out of my budget atm.
i am aiming for around 2~3mm for that part.

today is just a quick test nothing special about it...
since the cooler don't have the right mount i had to use my hand to hold the cooler so it not gonna move around.

here is a picture of what most likely gonna be the ending product
(water block is taller than that)

[HybridChiller]

i have copper here 40 x 40 x 10mm if you need some?

[kikicoco1334]

that would be perfect! you sir have a PM on the way

Did my eyes deceive me? Thinking I saw an EVGA 462 mobo and a CRT monitor?

nah, couldn't be, CRTs don't exist anymore :laughing:

I already told him he needs a new screen :laugh:

[Neuromancer]

CRT is good for leaving in the garage no worries about it going below freezing and getting damaged :)

[PhIlLy ChEeSe]

CRT'S are still used by old school gamers as they claim they run higher resolution/better. Great work log KIKI was gonna say they have copper plates on Flee bay.

[kikicoco1334]

that screen is my bench screen it's why i can't run vantage or some of the newer 3D benches

[kikicoco1334]

new stat...
from room temp 26.8 C to 0 C takes 7.5sec
from room temp 26.8 C to -7.7 C is 23.7sec
from room temp 26.8 C to -8.8 C is 32.5sec

as far as i know, -8.8 C is the lowest for 12v @ 22A

Is there a way to adjust it, think you need one of them special PSU to do that right?

[kikicoco1334]

I monna try use the power supply that's powering my piano see if it's gonna make any diff at all

Piano? :ohcrap:

Are those temps with a water block on top of the TEC? Under load or not on?

[kikicoco1334]

those temps are just the TEC it self no additional heat at all.

not my piano the charger for my keyboard that's hooked up to the computer
i'll post the pix of the block in a sec

[kikicoco1334]

Uh, I doubt that is going to have the amperage for a TEC, more likely you will end up smoking your piano power supply.

Laptop PSU might work if it is the 150W variety.

(I have a 95W 150W peak universal charger for sale if you need one ;) )Will sell it cheap as I dont like fixing laptops lol.

[kikicoco1334]

i just found a 230W laptop charger i monna see if that thing works at all

[PhIlLy ChEeSe]

See you need my battery's! :laughing:

[Neuromancer]

Make sure its output isnt 17v. (unless your pelt will operate at 12-24 ;) ). Would have to check that on any laptop charger of course, most are in the 15-17v range I think. There are a bunch of 12v though

[kikicoco1334]

the TEC operates from 0~15.2V DC and 0~9A and the max out put on the stupid computer PSU is only out putting 12v(11.33) max. but it does out put 24A
my question is will it be able to some how make it take more amp?

[kikicoco1334]

Does anyone know why is it when i have it on the wires gets burn hand hot?

i am using just random cat6 cables, i soldered it to the molex heads and plugged it in to a 400w PSU

[Neuromancer]

OMG! Are you crazy? you need a decent gauge wire to pull 200+W.

[PhIlLy ChEeSe]

OMG! Are you crazy? you need a decent gauge wire to pull 200+W.


Did you ever see the wires in it though? There not heavy gauge at all.............

[Neuromancer]

Did you ever see the wires in it though? There not heavy gauge at all.............

You can go thinner if the wires use a less resistive material and they are inflexible.

But no I have not seen internal wires on a pelt before.

You ever see the transistors in a CPU? Still wouldnt want my 12v line powered by 22 gauge stranded copper or worse aluminum lol

[kikicoco1334]

yeah, i do need thick wires...

the wires on pelt is just same thickness as the stander molex maybe a little thicker

[MaadDaawg]

Found this to save you some work Kiki :D

thanks MD, the funny thing is i designed something like that when i was 16, my dad told me that was retarded, and then Ultra came out with it hehe

i think i still have the blueprint of it somewhere in the house lol

[PhIlLy ChEeSe]

I got some heavy gauge AMP wire if you need some, probably to big like 2 gauge or 1.

I still have a copy of a letter I wrote to "the President" when I was in grade school. Back in the middle of the cold war when we had drills for surviving a nuclear bomb detonated near your school. You put your head under your desk - :rofl: it was called "duck and cover:

Anyway, I designed a suit for wearing in areas with nuclear fallout, and I'll be damned if an exact pic of it didn't show up in the newspaper a year or so ago! It was for chemical or bio shit if I recall.

The only difference is that mine had little tubes to shit and piss out of but the paper made no mention of those.

If only I'd have patented it when I was a kid, I'd be fuckin rich now :(

Hi guys I've read entire thread and I kinda saw myself on kikicoco1334 posts.
I tried the single peltier layout once and it was really awful. Using a H70 with two 197cfm deltas I was only able to keep an stock 2500k at 40ºC above ambient and a sempron140 12ºC bellow.
Going against everything that I read about it I tried to do what kikicoco1334 first wanted and I made a sandwich.
I hadn't read this thread before doing it =P so just to report what I'm facing here.
My original Idea came from a different concept. I wasn't going to make a sandwich, I was thinking about putting them two side by side. When I asked the only Brazilian block designer and maker about a cooper plate to put them inside he told me to be impossible to fit it on any mb. I agreed that and he came up with the idea of sandwiching them... As he was unable to build my plate I went to a DIY way.
I bought a pack of square cooper shins, some arctic adhesive thermal grease and build a sandwich of two 6x6 peltiers.
My scheme was a small layer of cooper a little bigger than the CPU, then a layer covering entire Peltier cold base, than a symmetrical layer between both peltiers and I would use a H100 directly on the top of the second peltier.

For few seconds I know it work. I couldn't test it on a cpu because I couldn't get wire good enough to survive more than 30 seconds turning the top peltier on.
I thought weird not being able to keep the system on using a single PSU, both peltiers shut down a Corsair 550w and 650W so I needed to plug each in different PSUs even seeing that they don't pull more than 65w from the network. And only the peltier directly attached to the H100 is melting the wires... I'm a bit afraid of soldering the metal plugs directly to the original wires and end up melting down my PSU's wire... I don't know.

Is it possible to melt my psu wires plugging this top peltier directly to it? This is where I got stuck...

I just wanted to see if I could gain any degree doing all this craziness..

[kikicoco1334]

i kinda just stopped playing with the peltier because it power to cooling ratio just wasn't worth it. had to use an extra PSU just to power the little sucker

[Gnidaol]

=( In my test I needed to use two extra PSUs since I'm using two suckers, it really don't worth the power it needs as far as I saw too...

[kikicoco1334]

Update! Fixed the wire overheating prob XD
instead of using stander computer wires i grabbed a pack of 18g speaker wires. now it looks better too!

but yeah it's really not worth it other than just derping around with it
