Antec TriCool 120mm Trilight LED Computer Case Fan - High Performance Cooling for PC Gaming, Workstation & Home Office Desktop Computers

These have the Green LED lights. I bought 3 of them to replace some burnt out fans of the same type in my Antec 900 case. Install was easy, fans work great, fast shipping, arrived in promised condition and price/value was great for these.This has been my favorite fan for my PC and mining rigs. Speed switch is very useful for controlling the output of the fan. Cost/performance is excellent.These fans work well as a replacement for the blues fans that came with my antec 900 case. They also have the same 3 speed fan control. The only difference between these fans and the original ones are the power connectors which are 3 pin vs the original ones which were standard power supply connectors.I have have used Antec 3 speeds for many years. They now compliment my Fractal Define R5 with the lowest noise levels and cooling efficiency which I have ever gotten.
