I have no idea why this brand is slept on lets be reall all fans get damaged during cleaning so why buy Corsair, Noctua, Lian Li, when you have to replace them out of your jet engine, every 3 years, the connect feature is extreamly convinet, i purched 2 x 3 packs because i need 4 fans in my case, i only have one single fan at the and you can plug in the, side shrouds to cover up the wireing on both side and it all looks smoth and clean as hell. im about to buy another pack get that push /pull setup.
