either way, you'll be suprised at your temps if you've never used an all in one or custom liquid cooler before. suprised the shit out of me, actually got limited by my motherboard of all things when it came to overclocking, 1.3v is the max it allows, i was getting ~71-72 in prime 95 at 4.7ghz on a dinky little h70. Cant go higher because i need more volts, decided to stay at 4.5 which ... on the h70 in prime 95 scores better temps than stock clock of 3.5ghz on stock intel cooler 62-63 max after 15 mins.
