Hi I have i7 2600k for years...and recently it gets hot. In my country upgrading or buying another pc is impossible, so I decided to buy CPU cooler for heat and overclocking... * I have to choose from this list(price order) : Thermalright TRUE Spirit 120M BW Rev.A Thermalright HR-02 Macho Rev.A Deepcool GAMMAXX GT CPU Cooler Cooler Master Hyper 212 LED Turbo Black Edition Cooler Master MasterAir MA610P RGB my pc : i7 2600k ASUS SABERTOOTH P67 4*4 Adata dddr3-1600 Nvidia gt 520 with broken fan 685W Power cougar evolution Case 1)witch cooler? (Performance is important, not rgb.and sound of the cooler) 2)with any cooler that you chose, should I remove any of my rams? 3)is it worth it? Considering that my CPU is very old and very used. and with knowing, those coolers are not cheap in my country. Sorry if my English is not good. Thanks.
