The SilenX iXtrema Pro IXG-3F2 optional fan kit
SilenX ships the optional fan kit, the IXG-3F2, in a plastic blister pack that exposes the fans to their buyers. As you can see, the IXG-3F2 comes as a three piece, 80mm set of fans. The 18 dBA that is noted is per fan at maximum RPM. SilenX has also included the specifications and compatibility listing on the fans as well. One thing that I see off the get go is that SilenX has no stickers on their fans that are displayed on their website. The Fans shown on site are also LED, which I do believe this set is not.
From the back of the box you can see the back of the fans and a sneak peak at the included goodies at the bottom as well.
After removing the fans from the snap together blister pack, this leaves just three fans and some extra wiring that is included along with the IXG-3F2.
You can see here that each fan has its own short 3-pin power lead. From the bottom the three tabs that lock the fan to the cooler are more easily seen. The small rectangular holes by the serrated edges I was on about earlier is where these three clips lock into place on the cooler. SilenX finishes off the fan mounting with a hard plastic tail to route the wire under to avoid any fan blade meets wiring mishaps.
The IXG-3F2 comes with a handy assortment of wiring. There is mainly the three way splitter for getting power to all three fans if needed in your installation. To the left and right of this are varying degrees of resistance built in to the wire, so you may lower the fan speeds from full without one, to adding one inline and lowering the overall voltage to the fan in two different stages. Every connection is 3-pin just like any fan header on a motherboard would supply.
There were no instructions provided with the fans, but I think this set up is pretty self-explanatory. The fans could go on either way, depending on how you're choosing to power this set-up. When you get them lined up with the punched holes in the fins, just press gently until you hear them click into place.
One thing I did run into was that the fans are not easily removed. They are locked on with all three tabs and are near impossible to remove without feeling like you are seriously going to damage either the product or yourself while doing so. Just as a word of advice, be sure you have the fans set the way you want them for the duration, as they aren't easily changed later on.
