Testing & Temperatures:

The fans were tested on an ABIT KT7A-RAID w/Athlon 1.4GHz @ 1.87v. The board was placed on an open workbench to keep the ambient temperature controlled and constant.

In the charts of the temperatures below, you may wonder what it means when it says "top" and "bottom", so here is a quick explanation:

Volcano 6Cu+  1.4GHz @ 1.87v

GlobalWin WBK-38  1.4GHz @ 1.87v

Graphing the idle and load temperatures from the two heat sinks above leads to an almost exact match in performance among the various fans. If more heat sinks were tested I'm sure they would follow the same pattern. As one can see, the 80CFM 80mm Delta dominated all. More about the temperatures will be discussed in the conclusion.

Conclusions:

First off, the stock fans for both heat sinks were 60mm 38CFM models, which everyone knows how loud they can be. When I was testing I thought some of the higher CFM rated fans would perform better, but they were barely able to keep up! What I forgot to take into consideration is that the small increase in CFM from the fans I chose have a larger area that they must blow air on. I guess you could say that the air stream is less focused on the heat sink when you put a larger fan on a heat sink that was designed for a smaller fan. The 80mm Delta fan overcame this problem by pushing a monstrous 80CFM of air on the heat sink and surrounding areas. Delta also makes a 92mm fan that pushed 110CFM of air which I would gamble could do an even better job of cooling, if you can locate a place that sells it.

Besides the stock 60mm and the 80mm Delta fans, the rest of the pack are near silent. This to me is the greatest advantage of the fan adapter, having the silence. Unfortunately during testing the Thermaltake fan wasn't reaching its peak CFM so it might of been able to lower the CPU temp by a degree or two, however when it does reach max speed the fan is pretty noisy.

With that being said, if I was going for all out performance, then I would have to choose 80mm Delta fan which gave about a 7F drop in temperature over the stock fan for about the same noise level. However if I was going for a quieter angle, then the 92mm Y.S. Tech would be my first choice.

The great thing about the Amuzuma fan adapter, is that if I want to change to a smaller or larger fan at a later time, I don't have to buy a new fan adapter, I can simply swap out fans and adjust the mounting risers if need be.

Lastly, I would like to thank Amuzuma for sending the fan adapter to review, and also Heatsink Factory for sending some of the fans to use for testing the adapter. You can find where to purchase this adapter from the Amuzuma website, along with more information about the product. One of the first stores that has the fan adapter in stock is Sidewinder Computers so head on over there and check them out!.
