This is also why many all-in-one CPU closed loop water-cooling solutions come with a thick 120mm radiator and fan combo. Should your case have two 360mm radiator mounts, it's absolutely worth taking advantage of available space and mounting a 360mm radiator to enjoy more surface area for heat dissipation. So if you're planning to cool just your CPU, you could get away with just a 240mm radiator and a single 120mm fan. Each component (CPU, GPU and chipsets) will require at least 120mm of a radiator or 240mm to be safe with overclocking. It's also worth considering how many components you'll be cooling in the water-cooling loop. You will need to check what fan mounts your case has and go from there. For example, a 480mm radiator can hold four 120mm fans, while a 280mm radiator can have two 140mm fans attached. Update: Our guide to quieter case fans and case fan size differences can. The characteristics of the fan are determined by blade shape, i.e.: 1. While 120 mm fans are by far the most popular, 140 mm fans can be fairly useful, too. You can expect a feature about fan bearing technology and fan noise level reduction to be published over the next few days. The centrifugal fan has an inlet on the axis of rotation and outlet from a scroll casing 90° from the inlet. These measurements refer to the length of one of the fan’s four sides.

Depending on your requirements, you'll need to choose between various sizes, which are determined by how many fans they can hold. For most PC cases, fan mounts come in one of two sizes: 120 mm and 140 mm. It deals with finding the right size for the computer-related elements to fit in, the presence of all the case fans available, and whether water cooling is applicable to cool the systems. Contrary to popular belief, there are some areas where size really does matter, and radiators for your PC are one of them.
