Hey, I'm getting this rig (http://www.cclonline.com/product/152773/NoMfgCode/Desktop-PCs/CCL-Elite-Raven-IV-Gaming-PC/CCL-EL-RAV4/), and Ill be playing games like DayZ and PlanetSide 2, but the site charges £25 for customisation along with the customisation itself. For heavy gaming, will the standard cooler suffice? I won't be OC'ing. Thanks!
