Dears, :welcome:

I'm kind of giving up thermoelectric cooling for my extrem cooling project (they draw to much power and turn out to be kind of bulky on the end). I built a water cooling TEC system.

So my idea is to change and start looking for small compressors. I gave a look around the forum and found 2 options from this manufacturers:

- Aspen (1.3lbs - www.aspensystems.com/minicompressor.html)
- Mitsubishi (6.6lbs - seems that Thermaltake is using one like this - http://www.tweaktown.com/news/9137/index.html) - but this one here from Thermltake is much smaller than the Mitsubishi smallest rotary compressor (I guess that this compressor in the picture above is 2.5" wide and 4" tall, so should weight less than 4lbs).
- Embraco (no idea, seems to be very small and mostly for notebooks, but.... http://www.legitreviews.com/article/567/1/)
- "Little Kim" (Star882 - It was intended for servers and runs on 370v DC, and weighs about 10lbs)

They seem to be rotary compressors....

But... seems that the first is very expensive and the second/third hard to find. :rofl:

I need compressors with cooling capacities similiar to the small aspen compressor. The one from Thermaltake seems perfect... any idea when they will be selling their system ?

Are there any other options ? Someone knows where I could find them ? Anyone selling one of those or similar ones ? :shrug:

There's also a "Little Kim" compressor that is also an inverter drive rotary compressor. It was intended for servers and runs on 370v DC, and weighs about 10lbs.

Couldn't find much information on it, however.

Thansk for the input!

Hummm, so, now we have 4 compressors on our list.... 2 with almost no info available (Embraco and Little Kim), 1 very expensive (Aspen) and 1 difficult to find (Mitsubishi)... our list is growing!

The inverter compressors seem to be the best, they can handle idle and full power much better than on/off compressors.

Seems to be a trend (Aspen goes that way), Mitsubishi not yet... the others who knows....

Small enough?

A guy on another forum got them for a in case build :)

Cute eh?

I'm not sure wether i founded this again but there was some company starting to build custom Phase-change coolers for use within Cases.

Looks pretty phat to me ;)

Sure, this is perfect, as I listed in my first post, but.... expensive as I figured out from your posts :yepp:

So I'm trying to get some cheaper ones U$ 100-200 range if possible. Otherwise I can't justify the price, despite its cuteness

This is the Thermaltake solution...

Any idea who could sell me one of this ? Really cool!!

thats one will not work with freeze pressures.

Hmmm ... this might be a decent idea to try cooling chipsets or memory! I wouldn't want to use it for CPU's or GPU's though. I see that there is no insulation on any copper ... I am guessing that it is not needed because the temperatures are above dew point? Or is this just the pic before insulation installation?
