I have a i7 870 with gtx 480 graphics card, cooler master centurion 5 case, thermalright macho cpu cooler and 3 case fans but the temp under load is 75 degrees I have reapplied the thermal paste which did drop the temp down from 86 degrees I have cleaned all dust out of case with a air compressor what else can I do to drop the temp? by the way 2 of the case fans are brand new. the case to me seems cluttered with hardware but cables are tidy.
