Gallery showcases the dustiest, grimiest PCs in Germany — 400 images of fascinating horror for PC DIYers

Dust overload

Dust can literally choke your PC, and a level-headed enthusiast will regularly check and clean dust filters, fans, and other parts of their systems. Though it might seem inexcusable to let dust pile up in a PC, it seems to be a pretty common occurrence. This weekend, Germany’s PCGH.de highlighted some of the worst “fluffy balls of horror” (machine translation) that have been shared by its readers. If you enjoy a scare, its ~400 picture gallery might shiver your timbers.

The images over at PCGH.de come with a disclaimer of sorts. “Please note: Many of the extremely dirty computers do not belong to community members, but were simply handed over to them for troubleshooting, upgrades, or cleaning, and photographed at the time,” pleads the magazine on its readers’ behalf.

As well as the horror of seeing these images, there is some dusty nostalgia to be had, as the PCGH.de user forum thread has been growing since back in 2012, when a guest poster first showed off a be quiet! CPU cooler caked with dust.

There’s a lot of old PC coolers, motherboard, graphics cards and more which you might recognize from back in the day – despite their cloaking in dust. See this old Gainward graphics card, for example, or this Asus Maximum III Formula-based system that was owned by a heavy smoker, and here’s a dust-caked Abit Fatality FP-IN9 SLI system, too.

Laptops, hurricanes, and maintenance

In this writer’s experience, laptops are even more prone to and more badly affected by dust ingress - due to users often placing them on soft furnishings and the relatively tiny cooling systems they use. However, they don’t feature heavily in this PCGH.de gallery.

Last year we reported on a similarly grotty looking PC system from North Carolina. However, we couldn’t blame the owner for lax housekeeping, as their Fractal Design Define C housed system was devastated by the terrible Hurricane Helene. That system was too far gone for even a capable electric duster like the Wolfbox MF100, currently 40% off at Amazon, to make a meaningful impact.

Last, but not least, it would be fun for our readers to share some of their 'fluffy balls of horror' (remember, we are talking PCs) alongside this post. Feel free to upload your latest dusty horror images here.

    At work about 35 years ago, when we couldn't load a floppy disk, we found that mice had carried chicken bones into the 5.25" floppy drives of an IBM PC XT.

    When I was a field tech for a major computer company in the 80's, I ran into something similar sans the chicken bones at a customer's satellite office.

    Most of my machine go through too many constant rebuilds to ever seriously pile up dust and thus the only one hit so far has been my pfSense firewall, which I never had any need to touch and still runs an original OCZ Vertex 2 120GB with 13 years of 24x7 operations and showing zero issues.

    That also sports a Kaby-Lake i7-7700T (35Watt) CPU and a low-profile Noctua NH-L9 cooler whose fan did in fact lock up once before the pandemic on an amount of dust that seemed very modest in comparison to these picture, in fact it wasn't very visible, but still managed to block the fan at the rim. The PC shut down without damage and could be restarted, but the fan not moving provided a strong hint that wouldn't last for long, while it was easy enough to clean and free up.

    I've been dusting somewhat more regularly since...

    That experience has made me somewhat wary, because as the firewall it's rather crucial and it came at a time when I was out of the country every second week so I've since gone for dual fan CPU coolers for redundancy.

    But it has also made me wonder: will the new trend toward reduced frame/impeller gaps make it worse or less critical, as perhaps not enough dust ever gets a chance to accumulate and is more likely to be broken up by the fans...

    I can already hear the "that depends" and it seems logial, as the composition of household dust will vary greatly with where and how you live.

    But I'd be interested to learn, if you have data to share.

    I had a Dell computer to repair that was over heating and crashing, I looked inside it and it all looked clean and problem free, I then looked at the front air intake grill which looked like it had a cover of felt on it, I initially thought that this “felt cover” could be a air filter to stop dust getting into the computer. I tried to remove this “felt cover” and found out that it was made of dust, perfectly formed into a sheet which looked like it was manufactured that way. Removing the dust repaired the computer.
