Like I said in my review of the 240 version........what else???
used these rads a number of time now, and always keeps me cool

If you want the best performance, choose this one

very good performing radiator. Excellent build quality and very visiually appealing. Well made EK Waterblocks. I´m using this 360 Coolstream XT Rad in my system with three TFC Feser Triebwerk radiator fans and my temps are really remarkable.

My CPU Phenom II X6 1100t overclocked to 4.2 Ghz, (temps. Idle 19°C !!, 100% load 39°C!!!) Radeon HD 5870 with EK Waterblock FC 5870,( idle 29°C, 100 % load 45°C!!!) Amazing. My system is shown on Youtube. Just check the FuenfamTag Channel.....

Thank you EK Waterblocks...

Many Greetings (Posted on 8/24/11)
