Review on 🌬️ Cabcool 1201-2 Two-Single 120mm Kits with Thermal Control: Keep Your Electronics Cool with coolerguys! by Bryan Moon

My run-of-the-mill closet has gradually become home to my audio/video and computer gear. Elevated temperatures and some burnt switches followed. I cut a few holes for this pair of fans, one for the inlet and one for the outlet. This is a complete set to solve such a problem. Works very well. They also sell a single fan version of this kit which may be enough for some but I went with the dual fan version. You will need at least a 5" x 5" hole to accommodate the fans. You will most likely need additional cables and may need to make them yourself. There are actually two temperature controls included, although my setup only needs one. Each controller can control up to 4 fans. Since the fans are not next to each other, I had to make an extension cable for the 2-pin Molex fan connector to get to the controller. However, it only has one power supply, so even if you want each fan on its own controller, you'll need a 4-pin extension cable unless they're very close together (which negates the need for two controllers). Molex connector (which goes from the power supply to the controller). You also have to get creative with the controller and its power supply.
