Components and Design (Cont’d)

The copper base exhibits a very smooth finish and appears to be flat.  The base is larger than most, which provides good contact with the heat pipes for optimum heat transfer.

The Scythe labeled 120mm fan that comes bundled with the Infinity is a low speed model made by Adda (AD1212DS-A73GL) that incorporates sleeve bearings and is rated for up to 46.5 CFM, 23.5 dBA at 1,200 rpm.  This fan is relatively quiet at 12 volts but becomes virtually silent when operated at reduced voltage.

One of the features listed for the Infinity is ‘4 Fan Mounting Choices’.  As it turns out this isn’t quite as easy as it sounds.  A 120mm fan can be mounted to either of the wide sides but just doesn’t fit properly (in my opinion) on either of the narrow sides and getting the mounting wires to work on the narrow side is a bit of a stretch.  A 92mm fan appears to be a much better choice for use on the narrower sides but no fan mounting wires are included for them.

I also found that the fan mounting wires that come with the Infinity will only work with a 25mm thick, 120mm fan.  That’s fine if you’re happy with the bundled fan (which is excellent for quiet cooling applications) but it does limit the use of other size fans.  For example, I had to temporarily wire-tie the two 38mm thick fans in place that I used during testing.  (Thermalright clearly has an advantage over Scythe in this area.)

The Infinity comes with mounting hardware that supports the majority of Intel and AMD platforms.  The Infinity CPU cooler uses the same universal mounting system that Scythe has used on some of their previous coolers.   There are individual clips for P4 478, LGA775, and AMD K8/AM2 that push into slots in the side of the cooler base.  The Socket 478 and K8 clips attach to the stock retention brackets.

While certainly very easy to install, the Infinity seems like a very large (and heavy) cooler to be mounting this way.  I personally would have preferred seeing a more robust, bolt-thru style mounting, with a steel backing plate for both K8 and LGA775 platforms.
