Dirty & Filthy

I have in the past reminded various people that a clean PC is a happy PC... Pity I don't take my own advice.

My main workhorse PC, which sits in my living room, has been blue screening. At first I blamed Windows generally and Mr Bill Gates in particular.. However the real problem was closer to home.

Having discovered that the CPU temperature was rising alarmingly fast, I suddenly realised what the problem must be. So yesterday I got myself two tins of air and this morning set about dismantling the PC.

I wasn't quite ready for the full horror of what I would find lurking in the inner regions of, what until a few days ago, has been a fairly reliable computer.


Your PSU should not be coated with a blanket of grey fuzz. I hang my head in shame. But wait it gets worse...


Below is a Coolermaster Jet CPU fan.

It's full of fluff!

That's not a light fluffy coating. Centrifugal effect compressed it nearly to the consistency of hat felt.

Above is a stock photo of what a heatsink should look like.


Below is what I found when I removed the fan asembley.

The heatsink is heavily coated with bio hazard. As 90% of household dust is human skin... That's bits of me and dust mite poop you're looking at. All together now "Yuck!"

I must say I am very impressed with this fan. The fact that it struggled on, still managing to cool the CPU to a working temperature for months with all this crap inside astounds me. Let's face it this fluff didn't all appear last Saturday night, it's been building up slowly since I first built this PC two years ago. I really think this stands testimony to the fan design and construction. So well done Coolermaster. And I apologise for treating your product with such disrespect.

I had thought that my two cans of air would make short work of all this fluff... However this isn't a can of air... I know it looks like one and it says "Air Duster" on the side but it seems to me to really be a chocolate teapot, because I found it to be as much use as one. You get more liquid propellant than air and it's turned the dust to caked on mud on the motherboard in one place. These are really for blowing bits of office lunch out of keyboards and just to be fair I just tried that... Nope didn't do much beyond cooling the keys down with propellant.

So I did something really, really dangerously stupid. I put one can on the heater. Once the can was almost too hot to pick up it has quite a bit of umph... as can be seen in the test video below. But never, ever try this at home!... I am a trained professional familiar with the stress tolerances in aerosol cans... Errrr... hang on I better go see what that loud bang was.
