Oh. Sorry about that. Those two brands are the best, quietest, and move the most air. I,have both brands in my system. I cant recommend anything better than these quality fans. The fans you have arent bad but if you want to see a NOTICEABLE difference you will need to go to one of ones i suggested or you wont really see any temp change. I research your case and these 120mm fans will push alot of air given the size and dimensions of your case. Anything else might be alittle better but not much. Im order see see a difference you should go with high air flow fans or dont change the ones you have.
