Peltier water cooled loop

[Matriox]

So the components for this loop would be 2 CPU blocks, tubing, pump, Peltier Tec, old heatsink, and a reservoir of course.. Now everything is normal in my loop vs other water cooled loops except for the radiator. I want to use a thermal electric cooler(Peltier tec) which i'd put a cpu block/water block on the cold side and the old amd heatsink on the other.. Now since i'm just cooling water which then cools the cpu I should be okay right? also I will be under volting the peltier cooler since i'd need a whole other water loop just to cool the hot side of the peltier cooler. So my question is would this work? and if it does would it preform as good if not better than a radiator? Or would it not be able to cool the water to temps cool enough for the cpu to be oc'ed.. Also my cpu i'll be cooling is the core i7 4790k and i'd like to get cool temps on a 4.6-4.8Ghz overclock

nah, peltiers are not designed for such things

 

trust me, I graduated in computer science and physics (sorry not thermodynamics but swerve the calculations you know what i mean)

 

 

mate just cool it normally, don't try to be a hero, do it like everyone else.

I tried to read this....I really did. But that profile pic doee

So if I understand this, you're wanting to build a water cooling loop, but using a Peltier instead of a radiator? No, that's not going to work the way you might think. It's also going to take significantly more energy than a fan on a radiator. Just use a radiator like everyone else. You can use a Peltier to enhance the cooling of the CPU, especially when coupled with a water loop, possibly even take it below freezing, but there are additional considerations to bear in mind. But using a Peltier as a substitute for a radiator will not only waste energy compared to a radiator and fan, but I don't see it working to nearly the same degree, especially since you'll still need a fan to cool the Peltier.

OK, the only possible benefit from the peltier elements in potentially sub-ambient water temperatures.

 

But to do so, you have to keep the hot side of the peltier as close as possible to the ambient temperature. The OC'd 4790k will produce up to 150 watts, so you need a 250-300 watts pelter block (with a 150 watts perltier you have no temperature difference left). So you are looking at 400 watts on the hot side!

 

This will deffinitly overwhelm your "old AMD cooler" (~80 - 150 watts cooling capacity estimated). With a good water cooling loop this is possible, but than you have two complete loops in your system. Also you should regulate the peltier power otherwise you will cool down the wather to much on low load situation and you have to deal with condensation.

 

I made some research about perltier while planing my passive cooled rigs (look in my sig.) and I'm using peltiers to recover electrical energy from the heat output of my GPU.

 

Your dearm is possible in theory. But it will require a lot of work, research and effort.

I think it would be better to do this:

 

Cold side directly on CPU.

Hot side on waterblock, watercooled

I think it would be better to do this:

 

Cold side directly on CPU.

Hot side on waterblock, watercooled

Having it directly on the CPU wouldn't really be best. It'd probably be better to have a copper plate -- probably 2mm to 3mm thick at most -- between the Peltier and the CPU. For one, that plate will be more likely to attract the frost that will form. But otherwise having the hot side on the water block actively water cooled would be better than trying to air cool it.

-SNIP-

 

Peltier waterblcoks have been done before but they aren't exactly the greatest if they go below ambient temps since it can start at a certain point cause condensation and you need to properly insulate for that.

 

On a 4790K if you get a good chip you can get a good overclock with it without having to resort to peltier cooling to keep it cool.
