Hi , my cpu fan is starting to become noisy and it's not as quiet as it used to be when i bought my computer 10 months ago..I have a cooler master and the average speed is 1660 rpm..I recently tried to install a intel cpu fan on there but it was hard because of those plastic caps around the pins..Im looking for a cpu fan that i can just screw it with a screwdriver but not those plastic pins cpu fan's ..Where can i get a quiet and good quality cpu fan that is not noisy ? What brand would be good ? Please help as it would be appreciated..
