Three things decide which fan to buy: the size the case allows (usually 120 or 140 mm), noise, and whether you want lighting. The ARCTIC P series is built for static pressure on radiators and comes singly as well as in three- and five-piece packs, handy when every case fan is being replaced at once. Darkflash models with ARGB add colour — just make sure the motherboard has a 3-pin ARGB header.
