so someone told my to turn the fans round on my h80i cos they where on the back vent but pushing air into the case so i turned them round and now when i start up my pc only one fan works so i turned them round and the other fans started working so im guessing its a problem with the power one of the power connections but i have no idea what to do now plus it wont show up in link software anymore and the fan that is powered is making a god awful sound thts rlly starting to annoy me
