No a 4pin fan, from sharkoon 120mm rgb nothing special was just an ez install but for some reason my pc wont turn on again suddenly, think its the motherboard.tl:dr
Wait, a 3 pin fan? Did I read the OP correctly that you "reconnected my cables" What exactly did you have to do to install this new fan? I don't think I normally unplug things to install a 3 pin fan, although everyone does their PC a little different..
