If you are overclocking your system or and just running some high performance memory, you've no doubt noticed that your DDR or DDR2 can actually get quite hot.  Many enthusiast oriented memory companies have products with pretty good passive cooling, but sometimes even that is not enough if you have poor air circulation in your case.  Today we are taking a look at two different solutions to hot RAM in the way of the VIZO Armada II RAM Cooler and the Thermaltake RamOrb.  The VIZO solution simply clips onto your existing RAM and provides extra air circulation.  The Thermaltake solution is much more elaborate and requires a few minutes to install.  Which one provides better cooling?  Keep on reading to find out.


VIZO Armada II - First Look:

The first candidate on the bench today is the inexpensive VIZO Armada II Dual-Fan RAM Cooler.  This cooler comes packaged in a friendly clam-shell package that required removable of a single staple to open.  It can easily be opened without damaging the product yourself thanks to the knife-free ease of opening.

As I mentioned the Armada II is the simplest cooler of the two, and this is why; the Armada II is simply a set of 40mm fans strapped to a spring loaded clip.  Installation is a quick process.  If your memory has heatspreaders, simply clip the Armada II onto a stick of RAM, plug in the fans and you're good to go.  If you have RAM without heatspreaders, the clip may damage the chips so VIZO has included a pair of foam pads that can be stuck to the RAM where the clip makes contact.  This protects the RAM and still allows you to use the Armada II without heatspreaders.
