Pros: Very well built! Moves alot of air! Works well with controlers. Is almost Silent with a controller!

Cons: They are 5 years old and still work so none

Overall Review: I used 4 of these in a server build 5 years ago. I have not had a single failure! This is even with the server sitting in a small closet. They are connected to a fan controller and they only spin at 1100 RPM most of the time. This seems to be less then half of their operation speed. Even at a low RPM they move alot of air. This is good because it is almost silent!

Pros: Adds cool factor to case (no puns). Gives you an "at a glance" option for monitoring you temps. Controls fan speed.

Cons: Not well made. Locks up every so often. Randomly starts beeping every 6-10 hours then stops, even though nothing is wrong. Wires are too short to be able to get them where they need to be while keeping them tucked away.

Overall Review: I've had this running in a server for almost 5 years sitting in a closet. It has preformed it job well. I would give it a better rating if the cables were longer and that it wouldn't beep so much! But I just wanted a display that I could check the temps without having to log into the server. If you buy this, I would suggest getting the biggest fastest fans that you can find. That way the controller will not need to spin the fans very fast and they will be almost silent. I used 4 of these. http://www.newegg.com/Product/Product.aspx?Item=N82E16835185054
