your cooling what looks like a few hundred watts of heat so I'd do the modds you need to atleast have a total of 3 120s. That can be a 240 and a 120, three 120s or a 360 but thats a lot of heat man and it needs to be removed
just a 120 can't do it I dont think, hell I have two 240 rads on my quad and shes still a bit hot
