My father recently complained about the noise my system makes with 4 Corsair quiet edition AF fans, r9 290, and a Stock AMD heatsink. I told him that unless I buy a better heatsink and fan, the noise will continue. He said, 'All right lets go to the store, they cost like 10 dollars max, hell even a dollar. Anything more and you are just paying for the brand" I smiled since a DECENT heatsink costs like 30-50 and a fan is around $8-15 each. I cant really put it into words because I dont know, but can you tell me why they cost what they do, and what makes aftermarket fans/coolers so special?
