Thanks MRK, I want to replace the fans as I think the sharkoons will be much better for airflow. The extra cabling issue is so I know I have enough length on things to hide away out of sight.
Hi There - I wanted to offer a word of experience on the Sharkoon Silent Eagle 2000 fans. I recently bought one and tested it at full speed (2000 rpm) and I have to say I was disappointed with the noise level - airflow was good but at 2000 rpm it is certainly too loud for my taste (even louder than my cheap GPU fan!). I don't know whether this is down to fan construction or just a side effect of running at such a high rpm. If you're planning on splashing out on a few Sharkoons and running them at full rpm it's going to be loud.
I have an Scythe S-Flex 1600rpm fan on order to replace the Sharkoon as Scythe's 1200rpm fans have been very impressive and have great reviews. I've not managed to find an reviews of the Silent Eagle 2000 - only the 1000.
