Air Cooling Fans by Size

Fans by Size

RGB Fans

Fans come in a range of different sizes from 40mm all the way up to 220mm with the average PC chassis fan coming in two sizes including the 120mm and 140mm variant.

Chassis Fans

Case fans generally come in two core sizes including 120mm and 140mm versions. Apart from the fan diameter and location of the holes to attach to the chassis both are pretty much the same. Occasionally cases have a front or top 200mm - 230mm fan but with manufacturers producing more slim and sleek case designs, the larger fans are getting integrated less.

Water Cooling Radiator Fans

Radiators for PC liquid cooling come in all sorts of sizes and configurations, from single 120mm radiators (one fan placement per side) all the way up to monstrous 560mm radiators. Other than choosing the correct size you need to ensure the fans offer high static pressure.
