Scythe "KAZE MASTER ACE " 5.25" Bay Fan Controller- Black (KM02-BK)

I bought this controller so that I could see what all the fans I own were spinning at.

I currently have two NZXT 200mm fans connected to it as well as the two fans from the Corsair H80. This thing does a great job of controlling any fan I have been able to connect to it. I even tried a 300mm fan that I had leftover from an old Aerocool case and it worked! So clearly it can handle a lot.

The design is sleek and blends in on my case. The number display is bright and easy to monitor during the daytime. I compared the temp sensors with another meter I used and it was only off by a degree or two. The temp sensor connectors are separate from the fan connectors, so you can just pull them out to keep it clean if you're not going to use them.

The only troubles I have with this, is the fan connectors can fall out very easily from the controller panel and set off the battery. I also didn't like how the battery goes off whenever you turn a fan off. I believe it does that so if you have a fan that isn't working, it will beep and tell you. Which is a good feature, but I just took out the battery because sometimes I turn some of the fans off.

This has been a very reliable fan controller, so I give it a 5/5.

Features are a plus black gloss/chrome trim faceplate, LCD display with RPM + temp sensor. Temp sensors must be routed to hardware making for lots of wires but they work fairly accurately. I have run up to 8 fans on this controller using y cables purchased separately well staying under the 1 amp per channel rating as most of my fans only pull 0.15 to 0.30 amps.

only CONS is temp sensors can break after removal Scythe dose provide extra, suggest they send more electronic adhesive tape, directions are minimal
