What's A Fan Adapter For?:

In a nutshell, a fan adapter allows you to adapt a larger (or smaller) fan to your heat sink. Most fan adapters that I have seen attempt to "funnel" the air from the larger 92mm or 80mm fan opening down to the 60mm opening attached to the heat sink. The first big difference about the Amuzuma fan adapter is they toss that idea out the window and provide a non-restrictive adapter that allows the excess air to flow around the heat sink to aid in better cooling for both the heat sink and your motherboard. Also being a non-restrictive design allows the fan to work at peak performance utilizing every CFM of air that it is capable of moving at the current system impedance. This adapter is also more versatile than others on the market, as it allows for the following configurations:

• 60mm to 80mm fan adapter - Attach an 80mm fan to a heat sink designed for a 60mm fan.

• 60mm to 92mm fan adapter - Attach a 92mm fan to a heat sink designed for a 60mm fan.

• 80mm to 92mm fan adapter - Attach a 92mm fan to a heat sink designed for an 80mm fan.

• 80mm to 60mm fan adapter - Attach a 60mm fan to a heat sink designed for an 80mm fan.

Why would you want to attach a different sized fan to your heat sink? Well, a larger fan can decrease noise levels, increase CFM levels (air flow), decrease CPU core temperatures, and possibly increase your computers performance.

So What's Included?

The complete package includes the ABS plastic universal fan adapter, an instruction sheet on how to correctly install the adapter, and a set standoffs and matching thread screws. Before I continue, I must state that the screws you see in the pictures are not the ones that will be included with the retail package. Instead of the short screws as seen in the pictures, there will be two sets of longer screws, four 1 1/8" and four 1 5/8" with each adapter. This will make the adapter compatible with all 38mm and 25mm thick fans. This change came because certain Delta, Sanyo Denki, Thermaktake, and other fans had either closed in screw wells or just not enough clearance to fit the shorter screw. By including the longer screws this allows the screw to go completely through the shaft instead of just trying to go through one half of the fan. I think from the pictures in this review you will gain a better understanding of what I'm trying to say.

Prep For Testing:

Being a universal fan adapter, it can be mounted on just about any heat sink, new or old. While some people might want to get an Alpha or Swiftech and replace their 80mm fan with a 110CFM 92mm Delta Fan, I think more realistically people are going to use their current heat sink to try and gain a little more performance and / or quiet their system down some. With that in mind, I chose two "middle of the road" heat sinks, the first was a Thermaltake Volcano 6Cu+, and the second was the GlobalWin WBK-38. The GlobalWin uses clips and not screws to hold the fan on, and unlike other fan adapters where you might run into a problem, the Amuzuma adapter is able to cope without a problem.

Again, here's the heat sinks used for testing:

• Thermaltake Volcano 6Cu+

• GlobalWin WBK-38

I also used several different size fans and CFM ratings in combination with the heat sinks above:

• 80mm Thermaltake - 46CFM-53CFM (Varies On Ambient Temp)

• 80mm Sunon - 30CFM

• 80mm Delta - 80CFM

• 92mm Y.S. Tech - 66CFM

• 92mm NMB - 55CFM

Since not many people are familiar with the Thermaltake case fan, I thought I would snap a few extra pictures of it. The fan is basically the same as the one that comes on the popular Volcano 7 heat sink. Along with the fan comes a set of four screws, 3-4pin adapter, and the finger guard, however I must note the finger guard is more cosmetic than functional, you can easily stick your finger through so be careful.

Here is an example of the WBK-38 with an 80mm fan on it. The fan adapter utilizes the stock clips from the heat sink to attach itself.

Next up is some pictures of the Volcano 6Cu+. Again it utilizes the stock screws to attach the fan adapter. The fan second from the left is the 80mm 80CFM Delta (very loud!), and the next two pictures are the 92mm Y.S. Tech. In the last picture you can see how much excess area there is around the heat sink for the fan to help cool the motherboard.

You can also check out a few more pictures of various combinations (including a Swiftech MC462 w/92x38mm fan on it!) @ Amuzuma.com.
