So about a year ago I put together my first gaming PC but I haven't used it much since due to work etc. I've only recently overclocked my CPU (i5 2500K from 3.3 to 4.5GHz) and the case I'm using isn't the best for getting rid of heat. The silencio comes with one or two stock fans that sucked so I replaced all of them with coolermaster fans. Here is what I'm using (included links to be clear):
So that's 4 fans in total in the recommended push-pull config. After overclocking the CPU it's about 35 degrees C at idle and on Prime95 the highest it went was 76 degrees. I haven't run many games since but I had it go up to 60 degrees at load after playing on a PS2 emulator for a while. I'm sure that it'd go higher if I played more or different games that used the GPU more etc.
So my question is how might I improve the cooling? I've read this: http://www.tomshardware.com/forum/331629-28-cooling-rou... but I was hoping that someone familiar with this case could give me some advice. I'm loathe to get a water cooling rig (seems too complicated for me - and risky!), so I thought maybe someone could recommend a different config or perhaps how I might swap either model of fan with a better one?
