lets talk thermoelectric cooling!!!

[grkM3]

I have been out of the electric cooling game for about 12-13 years now and had no idea you can get 500 watt tecs now on ebay for cheap.

I just ordered a 190 or so watt one to test with a 2600k and water cooling to keep the hot side down.

Some of the 400+ watt tecs say they can hit -60 C on the cold side.That is insane and could get almost ln2 overclocking numbers

Ill let you guys know how well a 200 watt peltier goes once it come in and want to see if anyone has messed with these lately.

I think 200 watts is up there but if I can lower the temps at full load by even 15-20c its worth it

Good luck, have fun and watch out for condensation.

 

[Joepublic2]

Yeah this is cool haven't read much about TEC lately even though it has 90% the performance of LN2 and about 10% the hassle IMO.

 

[janas19]

No, no one has messed with TEC lately. Overall, other cooling methods such as air, liquid, and phase change offer better performance per watt. Phase change cooling is costly to set up, but if you want extreme cooling it's the way to go, because it doesn't suck massive amounts of energy to achieve cooling like a TEC will.

Air cooling wont come close to a peltier.there is a guy running a amd phenom full load and his cores are at -2c with a 200 watt tec.

Ill glady waste 200 watts for sub freezing temps.

There are plenty of choices out there and this is more for fun and a hobby to see how cold thethey can get.

I think a 150 watt tec will blow away the best water setup you can build in a system.

Um, no. Like I said, it's been awhile since I read up on this, so tbh I'm pulling these numbers out of my ass, but a liquid cooling system's power draw is a pump and some fans. A fully built phase change can hit below -40 for about the same energy or less as a TEC plate.

do you know what you need to run a phase change setup? Take apart your fridge and try to jam all that in a case.and im pretty sure a compressor to run the A/C unit runs a heck of alot of power.


Did i mention you can get a 500 watt tec for about 38 bucks shipped lol


Check out what this little tec can do on an amd setup

Yeah I know, out of the box a Peltier is mad cheap. But the prob is they are also mad inefficient. A Peltier will basically cool 1 watt for every 1 watt it draws. While an alternative extreme cooling like phase change will cool more than 1 watt for every 1 watt it draws.

From good ole AT itself.

 

[grkM3]

I know how much it draws and efficiency was never a concern.you can buy all different tecs from all ranges and if you stack 3 500 watt tecs you are close to liquid nitrogen temps and it will cost you under 100 bucks.

5 galons of ln2 is about 350-400 dollars and another 200 for a canister to store it and it will last you about 1 hour of benching.

I dont know why you are hating when you even say that you are just guessing on the things you are saying.

This thread is about using thermoelectric peltiers for cooling.

Okay so from your own post a peltier can cool 1 watt for every 1 watt it draws.


Find me a cooler that can cool a cpu pushing 500 watts tdp for under 40 bucks please.you can buy a 500 watt tec on ebay for next to nothing these days and when i first tried them years ago they were really expensive and were inly like 65 watts max.

 

[BallaTheFeared]

Bah

A peltier doesn't cool, it just moves. You still need to cool the peltier.

If you're moving 200w of heat from the CPU and using 200w to so so, that's 400w of total heat you need to remove.
Buy a 500w TEC and use it to cool a 500w source, you have to clear a hell of a lot of heat...

here is a pelt making -16c with just a heat sink on one side.They def cool and companies are making very efficient tecs these days.

the watt rating on the tec is just how much it can pull and depending on how cool you can get the hot side is how much load it can take at that colder temp.

What you just said is 0% efficiency and would not do anything.If pelts dont cool please explain to me this video.

I have two thoughts.

1) TECs are probably easier to use these days on computers than a decade ago. That is because of the cumulative experience of the past decade in overclocking and cooling. Also, these days the highest end PSUs are powerful enough to run a full rig with multiple GPUs while still powering a TEC.

2) OTOH, seems to me that the limit of overclocks at least on Intel CPUs is how much voltage you are willing to pump through it, not how cold you can make the CPU.

 

[KingFatty]

If the TEC is just moving heat, how can you get such cool temps (e.g., below zero)? One video showed the guy with a water cooler stacked on top of the peltier, but what happens when the water heats up?

Considering getting one of these and adding it to my water loop. With the controller it maintains ambient temp, preventing condensation.

I wouldnt spend 200 on that,just buy a few low wattage tecs on ebay and play with the voltage to keep the temp right above freezing to avoid codensation building up and dripping on your motherboard

It seems simple in theory, but in practice it is a tad more difficult. Ambient and weather conditions will have an effect on the condensation. Your best bet is to insulate to be safe.

 

[grkM3]

I cant wait to test it out and yes def insulate the area to be safe!!!

Exactly. This is the main reason that TEC cooling is not more common.

Not to mention it's pretty risky if set up improperly. If you have a pump fail in a water loop, the block still can cool enough to prevent damage. With a TEC, if you have a failure without a cold plate in place, your chip is likely gonna fry since the TEC itself acts as an insulator. TECs used to be more popular, but many people lost good hardware due to cheap TECs.

1. TECs are not heat sinks... they MOVE heat
2. If the TEC is raited at 200W.. then it means it can MOVE 200W at the cost of 200W which means ur heat sink must be able to MOVE 400W.
3. TEC's have something called CoP, and a ΔT from hot side and cold side.
What this means is depending on the TEC and the draw a ΔT will form.
So the colder your HOTSIDE is kept the colder the Cold Side will be Kept.
4. If you can not keep the HOT side cold enough, the Cold side will suffer.
5. If you OVERSHOOT your tec.. mean u have more heat then it can move, the Cold side will compound and compound, eventually cooking whatever ur trying to cool.

Do research... TEC's are not MAGIC sponges or Yoshi's Stomache from Mario brothers.
They have rules which are bound by thermo, and it seems like your not understanding this Op.

 

[Ferzerp]

Let's just let him stack 3 500W units on top of one another and then post back here that his rig caught on fire because he needed to move 1kW with the second one, not 500W, and then 2kW with the third one Then he'd somehow have to cool the whole monstrosity (maybe he's making an infinite tower of peltiers where each layer draws twice the power of the last).

I endorse what the op is doing, if he hooks up a web cam!

 

[Absolute0]

Well good luck stacking a bunch of TECs together and hitting "liquid nitrogen" temperatures, -196c on one side and a waterblock on the other side moving 1000+ watts? Don't see that happening.

 

[aigomorla]

incase you guys are wondering i have done TEC's..

my final conclusion was:

"Cost too much power for the gains."
"not worth it for the gains in OC"
"another thing to add in the list of things which can go wrong in your system"

And the way i did it was with water... cooling the water, so you have more of a buffer..

Make sure u know what ur getting into when you play with TEC's.
Thats the important thing to note.
Because u see frost in video's doesnt mean it will frost when you apply a 100->200W heat source to the cold side.

I will bet you 1000 dollars that the 168watt peltier will drop my loaded cpu temps by at least 10c with the only thing i do is put tge tec in between my waterblock and hook it up to a 12v source.

Ill paypal my money right now to a mod here and he will give it to you if it dont work.you do the same and if it works i take your 1k

I like how we have people that have never worked with thermal cooling act like they know it inside and out from reading a few quick google searches on it
