Its your airflow. I had the same Raidmax case. Im assuming yours is the Astro. Got my Antec 900 now and it is alot cooler. 4 x 120mm Fans and one giant 200mm on top
I imagine it's noisy as hell too. My P180 has only two 120mm fans and it's not that quiet. I guess it's okay when you're not paying attention to it, but when you just sit there with nothing else on, it's quite noisy. Heck, I'm not even using the stock Antec fans either...the Yate-Loon fans I'm using are quieter and better. Still noisy though.
