Freezone CPU Cooler

So, i’ve actually had this for quite some time now, and figured i’d blog about it!

The Freezone CPU Cooler! What is it?…. a superior cooling unit using a patented MTEC (Multiple Thermal Electric Cooler, 6 to be exact) Technology in a compact design that fits inside any chassis with a 92MM or 120MM exhaust fan.  it is a closed loop and factory sealed pre-filled unit and offers a maintenance free construction with an average life time of over 50,000 hours. 

Installation for me was a bit of a pain because I had to pull my motherboard to get the CPU mounts attached, but no worst than most 3rd party air cooled systems like my Previous Zalman cooler which was loud, and kept my Core 2 E6600 running at 63 Degrees!!

This is a must have system for any extreme gamer/over clocker/ or heavy graphics and CAD users. it’s compatible with Socket 478, 775, Core 2, 939 and AM2

Currently retailing for $299.99 – $399.99 USD

The Freezone is a very interesting concept and design. The entire technology is made possible by a fairly old IC named a peltiers device, or thermal electric cooler, and is also well known to electronic engineers as the Seebeck effect.


Today Peltiers device look like a small sheet or wafer, with a positive and negative connection.

Thermo-electric effects in semiconductors cause currents to flow due to temperature gradients but also cause temperature gradients when an electrical current is applied. The doping density in the semiconductor elements is graded with the highest density at the high temperature end and the low density at the low temperature end. An electrical current is applied to the series connection of these elements. n-type and p-type elements are used to ensure that the carriers flow in the same direction.

If you can’t remember what n and p type materials are, or how a static transistor works, I suggest picking up “Basic Electronics” by Grob!  I’ve modified my Freezone a little bit. I do not suggest modifying your Freezone because it does void the warranty, but if you feel you must to help get that little bit more out of your system then the following tricks worked quiet well for me: 

  • Sanding the CPU block, there is pure copper under there! (the largest improvement of them all 7 degress cooler!)
  • Converting to a 120MM fan, using a fan adapter kit (Made the system very quiet and dropped temp by 2 degrees)
  • Sanding the Fluid Heat Exchanger and Heat Block for better contact (improved cooling by 4 degrees at full load)

If you do not currently have a Freezone CPU cooler, I would suggest picking one up. it’s cheaper than a phase changer, and can keep your system running ice cold! (no pun intended) 

In some cases I’ve seen it drop below ambient, this is not recommended though due to condensation issues. If your system if running below ambient… overclock it more!

BTW… if your wondering, my Core 2 E6600 is now sitting at 12 degress overclocked from 2.40Ghz to 3.3Ghz… i love this thing!
I soon hope to be zapping heat from a Quad Core Processor! i’ll keep you posted on the results
