most people will say get a wog cooler/monza, has been proven as best bang for your buck. process west have a few options for a bit more. I have a plazmaman kit on mine and I find it works well. I also had a f6 cooler on mine before I got what I have now and found it to be not up to the job however some have gotten good results with the f6 cooler,300+rwkw.
