ok so i have the i-5 2500k overclocked to 4.4 at 1.2 vcore with a hyper t-4 cooler on it i have one fan in the front of my cool master mid tower that sucks in air and one on the back that pulls it out the fan for the cooler push at the back fan. so i run HW Monitor it says that the overall core heat is maxing at 71c and ideal at 42c that seems hot should i add more fans or should i change to a water cooler?
