So ive been thinking of buying a COOLER MASTER Hyper 212 EVO cpu fan. Along with that, also a 4 pack of XIGMATEK eXTREME SILENT Series XSF-F1252 case fans, and i would need a fan controller for those, which would be an NZXT SENTRY 2 Accessories 5.25-Inch Touch Screen Fan Controller. All that comes up to around $75 without tax and shipping fees. Thats quite some cash for me to spend right now, since i dont have much to spend and i also need a new monitor and want to save up for same upcoming games. Would there be any noticeable performance gain with those fans installed and while staying quiet? Is it worth it right now? Any help and feedback is greatly appreciated!
