I have an "old" hp computer, when i got it (it had been running for years with no cleaning) and there was so much dust that when i got all the dust out...i relaized that if i wanted to hold all of the dust, id have to use both hands. Now ive called the computer dusty.

I work in a machine shop, you haven't seen a dirty computer until you've seen a shop computer. Some of the coolant from the machines is vaporized and floats through the shop, getting sucked into and settling on the towers. They are an oily dirty mess that can be hard to clean not only because they are so dirty, but they are also almost always required to be up and running.

It would have been interesting to see how the CPU and GPU temps would have looked like under three different fan setups. For me dust is not the key factor when installing fans. Only the temps are. I clean my PC regularly with a compressor and it removes everything easily and I enjoy it quite a bit to be honest. So more dust is not a bad thing for me actually xD....I would like to know if I can improve my temps for example by switching from an in between setup to all in or all out one?...Maybe you guys could make a video about that? Thanks and regards.

I bought an Acer slim desktop (AX3-100-EF10 for those curious) in 2013, and it's been on ever since without having been opened for maintenance - minus the occasional power outage... and when I opened it a few weeks ago? NO. DUST. INSIDE. Naturally, the first thing I said out loud? "Witchcraft!" since none of the cooling grilles were filtered in *any* way

The best idea, would likely be, to have regular airflow case but raised off the floor with no restriction underneath on an end table with a center hole cut out for bottom airflow without floor dust buildup.

OK, so why didn't you block all the open vents that are around the fans? I have mine all blocked, and only filtered ones blow in, and unfiltered blow out. I have almost zero dust after a decade of use. I only clean the filter.

Should have done temperature tests too. And making sure the case is properly filtered would be a good square one, before the rest of the testing.

Well, in spite of this I have cleaned my 10-year old dinosaur. Really collecting dust for 10 years, and I did NOT do any cleaning on it all the time. Fan setup? 1 intake. Probably half of the case was full of dust. Thermal paste was so dried that I got to use like a full syringe of alcohol and 6-8 coffee filters. Can't run any benchmark in it so oof.

if a pc is in a room where some person is inside most of the time, and lets assume you have a bed,couch or a wardrobe in that same room... in this scenario there would build up muuuch more dust than somewhere between two walls in an officebuilding.... would be very nice if you guys could make another video from a pc in a bedroom or livingroom, and then compare it with this 3 computers^^ (or the video at least)

Another takeaway, blow out your computer's insides regularly. Don't be like me when i was younger, and had a Pentium 2 system run for years without any cleaning. Eventually it started crashing shortly after startup every time, i cracked the case open and noticed my CPU heatsink fan had melted off (all the ribbons holding it on had partially liquified at some point, so my CPU had 0 cooling-because the heat sink was completely solid with dust bunny. Couldn't even blow it out, had to use a toothpick to clean it-and for those who remember what the old pentium 2 heatsinks were like you can imagine how bad that had to be).

If that *Fractal Design* case dropped the 5in Bays at the top and converted them into two or three HotSwap bays without having to open the case, then I would jump all over that case and call it a market disruptor for being so awesome at that price-point.

You call that dusty? The reason it seems strange that some people's computers get far dirtier, is that the sort of dust you get from a warehouse/construction area is different from the sort of dust you get in smaller, human infested spaces, especially if the human infestation doesn't keep the space immaculate. Dead human skin cells are normally the majority of the dust in a place people live in, and those skin cells are going to carry a bit of the oils from the skin with them...stickier than other sorts of dust, therefor gunkier. It's a fact that a closed place with little to no human activity, like an unoccupied house, storeroom, etc. doesn't collect much, if any, dust, since most of the dust inside most buildings comes from dead skin cells. That reminds me, my main box is overdue for a cleaning.

Seriously, you couldn't even build 3 identical builds, and just change direction of the fans? Let alone other factors that could of given you inconclusive results. Final results came down to common sense... Filters for intake fans. Wow, what would I do without these videos.

about a year ago I had to buy an old second hand Macintosh. when I opened it up it had some dust in it. the dust was so thick it had made a thick carpet over the entire inside. the motherboard was not visible. the dust carpet could be lifted off like a layer of felt. I used a vacuum cleaner on it to get most of the crap out. then I had to open up the psu because it was completely clogged with another carpet of dust. the seller said the power would keep cutting out... I wonder why....

What this video proves to me is that the best possible fan design for a system (with respect to dust management only) would be an "inny" where every case fan was shielded by a filter. Hence filtering all incoming air and preventing the type of dust buildup on the "outy" cases joints. However I'm guessing that both extremes would negatively impact cooling performance.
