I used to have water cooling, but after an accident of the pump failing, I am back to good old air cooling again. I am going to be fitting an SI-120 shortly with an Akasa Amber 120mm fan, but I wondered whats the best case fans I can buy? Because having a look it appears I dont have any case fans which is not really a good idea. So, how many case fans should I invest in? And whats the best sizes/makes?
