I am in a budget of 400 dollars. I was thinking of buying a 360mm radiator but i have no space for it on my case. I just have 2 fan outlets. I was thinking of using those 2 fan holes or however they are called i don't remember and leave the 3rd fan just there using airflow to pushout air again to the case and the fan on the back to push it out. I can buy a 240mm radiator and a 120mm radiator but it will be pricey. I have the cm force 500 case.
