Review on Thermaltake 200mm Pure 20 Series: Quiet High Airflow Case Fan with Anti-Vibration Mounting System - CL-F015-PL20BL-A by Antonio Baker

My case is missing the plastic strip at the top and it's so old I'll probably never find a replacement. This gave me "problems" with the top fan, it's so big. This is my fourth. The first three didn't have good protection, they never sat straight, and eventually the fan blades caught and started banging against the side until they snapped and died. This latest version of Thermaltake fan cannot get stuck because it changed the way it is placed. It took a bit of fiddling to install, but once I did it was like a brick. And keep silent. Between that and the water cooling, my PC runs at a constant 29 degrees Celsius despite being a gaming rig with an I-7 processor, 16GB of RAM and an Nvidia 1070 graphics card.
