Hi, What cooling capacity should I expect from a 240mm AIO CPU Cooler, for example an H100? Background: I'm having a bit of fun with overclocking, I've got an P9X79LE mb and a 3930k proc. I've been following the ASUS youtube x79 overclocking videos, but to 4.5GHz and a VCORE of 1.35 volts and it overheats and throttles under prime95. I replaced the old H100 with a Frostflow 240L, because the H100 is a reconditioned unit and I though it might be past it, and I've gone through a variety of fans. I think the heatsink is seated ok and I'm using gc-extreme tim. I have a additional large fan blowing onto the VRMs. I'm running Linux but the intel turbostat utilities work and the package power is 230W+under prime95. The Package temperature gradually climbs until the thermal throttling kicks in. So I'm wondering if a 240mm AIO cooler is sufficient. Any suggestions?
