I changed my cooler and gained some Cinebench points without tweaking anything. I replaced my Arctic Freezer 3 Pro 420 with the ROG Ryujin Extreme 360—both were set as intakes. With the Arctic, my Cinebench scores were in the low 46k range. The only tuning I have is PBO -20 on all cores and EXPO on the G.Skill. I guess you get what you pay for with ROG. Peak and idle temps also dropped by about 5–10°C across the board.
