With the help of the nicely detailed manual, installation was a snap. Our test bed used an Intel socket 775 system which unfortunately required the removal of the motherboard in order to install the retention bolts. If however you have an AMD socket 754/939 or an Intel socket 478 motherboard, removal of the motherboard from your case is not necessary.

The FHE is mounted using metal brackets that connect through grooves located on top of the block itself. The brackets are then securely screwed down using thumb screws.

The retention design is such that it can be adapted to any future socket releases with a simple addition of adapted metal brackets.

The rest of the unit is then mounted via the radiator exhaust fan to the back of your chassis. (Note: Be sure to plug in the 4pin power connector seen to the left above, as it will be inaccessible once the unit is in place.  Yes I do know this from experience!)

The unit radiator uses a 92mm fan which is not a common size for rear chassis exhaust fans. With this in mind the Freezone comes with a 120mm adapter in order to allow it to be compatible with the majority of cases on the market.  If you have 80mm exhaust port only then you are out of luck short of drilling new mounting holes.

Frankly, I have no idea why CoolIT Systems chose to go with a 92mm fan instead of what is now the standard 120mm exhaust fan. Aside from being compatible with ninety nine percent of all current cases, a 120mm fan would have been able to push more air with lower noise levels. In fact, I'm not sure I know of any case that uses a 92mm exhaust fan. Most if not all are either 80mm or 120mm (though some offer the ability to use any of the three).

In the Middle of It All

The TCM is fitted with two pieces of double sided tape and can be placed anywhere that there is room inside your case. The manual suggested along the side of a hard drive cage as being a good location, and I tend to agree with them.

The TCM is powered by a standard 4-pin molex connector. Two of the 3-pin fan connectors allow the TCM to act as a fan bus for any additional system fans being used, while the third is used to power the radiator exhaust fan. The 4-pin power adapter on the right hand side powers the TEC units, and the small connector just below it is the connector for the IC temperature probe connection.

There is also located a small thermal controller located on the TCM which can be manually adjusted to set the Freezone to run at either maximum cooling power, or at minimum noise levels. Out of the box the unit is set somewhere in the middle. A nice feature would have been to allow this level to be set via a front 3.5inch bay or rear PCI slot adapter, but the fact that the option is included at all is appreciated.
