Have a look at this High School Peltier Cooling system, the bars make it look real high tech. Have a look here for more information about peltier devices.

what a huge waste of energy – i already thought directly cooling stuff with peltiers was a waste due to their low efficiency, but this idea brings that to a whole new level …
… let me guess, you’re probably american …

This really isn’t all that wasteful in that it doesn’t have to be run expect when teh user wants to. In cases where the peltier is between the CPU and a heatsink it always has to run at nearly full power trippling the power wasted by the CPU.
Also, at a large scale peltiers, while inefficent, don’t use that much energy. Take the spare tire out of any car and you will save far more energy overall.

True, three years later, it wasnt the best idea I ever had…but this project went to completion and did what it was designed to do. Sure there’s alot of things I would do differently now, but at the time, with the 3 month design period we were given, I was very happy with the results. And as hello moto said it was designed so that it could be used only when you believe you require the extra cooling.

yeah maybe i was a bit harsh, but think about this idea:
an optionally peltier supported water cooling with a passive radiator – as long as water doesnt get too hot keep the peltier off and if it rises too much then heat the water going into the radiator even more whilst cooling the cooler water coming from it down even further.
Like that you can increase the efficiency of the radiator when needed with the peltier.

Very cool idea I like that. I’ve got everything lying around except for the separate water block to attach the cooling peltier to. Maybe I’ll give it a shot. When we were first brainstorming what type of cooling system we should design, a water cooling rig was our first idea. The idea was eventually shot down due to its lack of originality and the need to design a product that could be very easily implemented by just about anyone. While the idea of cracking the heatsinks off our PC’s might seem like a regular occurrence, to the other 90% of the world this can seem quite daunting. Thanks for the idea, I know what I’ll be working on in the machine shop tomorrow!

I’d say this is a great project, especially for a high school student. When I was in high school, several years ago, this technology was pretty much unheard of. Kudos to you and your team!

This is suxx! Cover ur mainbard with epoxy then put it into aquarium. And its done!

Arni, peltier coolers are highly insulative when not powered. You can’t have an inactive peltier cooler sandwiched between your CPU and your heatsink/waterblock, unless you’re looking to cook your core.

Set it up so you can use a small solar panel to power the cooler.

or a small nuclear reactor, mr Fisson anyone?

Nikita,
The idea is doable, if one hooked up a second waterblock to the existing system and attached a peltier with a fat air cooler to the second water block. (preferably housed outside the case) The water cooling system can then be ran conventionally or in high load situations the peltier could be turned on to pre-cool the liquid in the stage before it reaches the cpu/vga.

There is no water cooler. The system was designed to cool the air entering the case. Not to directly cool any of the components. In retrospect the system does has many flaws. Lol it is good to see someone actually taking interest in this thing so many years after I made it.

hmm … the criticisms surrounding the inefficiency of this device beg reference to low thermal conductivity and specific heat of air? this is why one cools cpu with direct contact to heat sink. for my system i run thick cable of isopentane cooled with N2, and top it with thick copper interface plus thermal grease.

the idea is sound but the execution is quite flawed. it looks like the hot air is blown out with small 40mm fans which is then sucked back into the system directly. There is already a pull fan at the back of the case so you only need a way to get rid of that excess peltier heat-away from the “cold” air inlet.

Well, grate idea, but can do with some improvement i will agree… For the critics, the clearly have not worked with tec modules before as to the way of implementing it is rather idiotic and ineffective. you will probably end up frieng your tec… I have been working with these modules for 4 years now as an engineer… I must say, not that good idea for cooling the pc, as cold air alone wont do much, but for a low power aircon on a biger scale, that would work!! Any way, the tec should be cooled by water, rather than the water by the peltier… that way you can get to -60 degrees C…. Rely nice idea you have here!!!!

Running a Peltier element between the CPU and a water block of a Corsair H50 CPU Cooler
The problem with this is it causes a build up of condensation on the CPU. However, I did not give up there! Reduce air temp in the case. Using two CPU heat sinks, 100mm plastic drain pipe, two 40mm aluminium blocks (hollowed and filled with silicon thermal compound) i was able to create a working, stable air cooler for the case.
Reduce the voltage to the thermoelectric element using smart fan technology via thermo voltage control, seal the element to the water block with a .5mm silicone thermal pad (ensure no condensed moisture between THE BLOCK/ELEMENT/INSIDE SILICONE PAD)
It’s not energy efficient (arni) nobody claimed it to be, but the thermo results are good!
