We're still between two houses at the moment but I finally moved my PC up to the new cottage today. I thought I'd best give it a bit of a clean as I haven't taken the lid off the box since I bought it two years ago! It has been incredibly noisy for the last few months and when I did get the lid off, I could see why...the two fans inside were absolutely caked up with dust and I'm surprised they could work at all
One good clean later and she's running quiet as a church mouse again!
