I'm about ready to assemble my Crossfire system and the only area left to address is cooling. I want to run air only and could use some recommendations on CPU coolers and video card coolers. My system specs are listed in the pull-down on the left. I've read so many posts across the 'Net that I'm close to making my final purchases but would like some opinions. I will be overclocking - strictly on air. 1. AMD FX-60 processor. I first bought a Zalman CNPS7000B-AlCu cooler for this processor but after reading some more, I also bought a Zalman CNPS9500 LED, which I plan to use instead. Am I good there or is there a better way to go? 2. ATI Radeon X1900 Crossfire Edition Master Card. I haven't found a cooler yet that I know beats the stock cooler ATI ships on this card. Since I'm going to be running a dual-card Crossfire setup, I'm concerned that I will run into space constraints if I use an aftermarket cooler for this card. 3. ATI Radeon X1900XT X PCIe 512MB. Same concerns as above. This is my dream system build I have been planning for quite awhile and now it's about to become a reality for me. I have all of the components except a decision on the CPU and video cards air-cooling. The Antec P180B case allows for up to 5 case fans and is designed for good airflow but the computer will be in a hot area and I will need the best air-cooling I can get. I've come this far and want to get the best air coolers for the CPU and video cards. I'd appreciate any and all air cooling recommendations I could get for the above. Thanks, and first post here.
