Hey. I am building a pc for the first time and I´m building it in fractal designs mini c. I am going to install a 240mm radiator in the front of the case and a gtx 1070 behind it and I was wondering how much space there needs to be between the radiator and the gpu? The cpu cooler is going to be a cooler master master liquid 240 with stock fans in case you wanted to know. Thanks in advance.
