Small form factors are becoming more and more popular: each motherboard and enclosure brand have several offerings in their lineups and their range is constantly expanding. The time when small was linked to limited power is long gone! These mini PCs can pack some serious punch and are capable to even outperform a full desktop offering, hence why gamers are also jumping on the small form factor wagon as it combines performance with ease of transportation. There are some drawbacks on several aspects alike the amount of possible storage, graphics card compatibility and possible cooling options. Today we are going to tackle the latter and will test three coolers specifically designed to be compatible for this popular factor. We will put head to head the Corsair AIO H5 SF, the tiny Noctua NH L9x65 and the Cryorig M9i tower cooling solution.
