I'm building my pc soon and I want to overclock it, I have an Intel Core i5-7600K cooled by the Cryorig H7, an MSI GeForce GTX 1070 Ti Gaming 8G (it has 2 MSI TORX 2.0 fans) and 2 case fans included with the NZXT S340 Elite. I still have enough room for 2 case fans and the Cryorig H7 has extra mounting brackets for another fan. I wanted to know if this is enough to overclock or if I should buy one or more fans extra.
