Oh hi, I just replied to your email earlier this evening. Just wasn't clear on whether you had 667 or 800mhz mems. You can ask angelshonny and others who have bought FBdimms from me, nobody complained about their ram holding them back any more

The ramcoolers I use are by EKL Germany and yes, they are intended for standard DDR2. However you can mount them on FBDimms as well using the supplied heatpads and a certain technique
