everyone's been waiting even very famous celebrities for the results of the one-year airflow test yes my friends we are still running them and we are doing the video but there's only one small problem Luke doesn't work here anymore to do the stunning conclusion so we're gonna have to walk all the way over to floatplane media's office and get Luke to help me check out which one worked or if they'll didn't work brought to you by tunnel bear tunnel valve leaves the Internet should be more open and private try it out for free at tunnel bear comm /l tt will have that linked below I actually had very little involvement in this project what is going on here well there's any OD and in between II like there was before OD has more fans blowing out I think all the fans blowing out any has all the fans blowing in and in between E is fairly balanced they have all been running for over a year behind the old set yeah but then we built this mezzanine that we're standing in and then we tore down that set so once the mezzanine was done and before the set got torn down they got moved up here to the office but they were out in the warehouse under the worst possible conditions literally construction zone let's not entirely dismiss the possibility that we will learn something today even if what we learn is that were idiots and we don't know how to perform a controlled experiment so which one is supposed to be the worst by the conventional wisdom I think most people think that all in is the worst okay so let's get the other ones no wait we bleep no no all out is supposed to be the worst but all in these are these are the top and Packers this is supposed to be the bad one all out and then it sucks air into the crevices yes okay okay so this is the one we start with so the outside isn't really something to judge because they would have all had a bunch of dust settle on the top and it's not that terrible I mean like I'm gonna do one streak on the power supply I mean it's not great not great having a look at our fan though really makes me wonder how it is that people get their computers disgusting enough to be like gummed up well how there's it there's cobwebs that bottom filter was definitely doing something and this is OD this is OD so that means this one it wasn't pulling through a filter he should have been sucking all the air in from elsewhere so this is another thing we have to be careful with this this is another thing where it's fairly case-specific because a lot of cases don't have that huge filtered mesh on the bottom so you can also see here that with the audi case we've actually got a lot of dust build up here and you can assume that for every bit of dust on this yeah more got pulled in yeah actually this is a good thing they're both sort of a good thing but it's a good thing to see so our graphics card does have a dust bunny inside it yeah so that's some buildup so our CPU is good yeah so on the top was good so it actually didn't suck that much in because they're just blasting everything else yes so the CPU is like sheltered almost because everything around it was like no get out yeah so you can actually you can see some dust streaks on these cable management holes and then but not much I bet you the graphics card was breathing through here and through here how explains clean because it's through a filter actually that area of the filter is pretty concentrated any dust that's caught in this filter was already in the computer okay interesting so that's all pulled from inside and these fans have a fair amount of buildup in the matcha tea I think the main takeaway with this one is that even in a construction zone where clearly there was a lot of dusty buildup on top most of your dust is coming into your case from the bottom so if you put your computer on the ground because we didn't have fans blowing out of the bottom that's right yeah you might have a bad time when do the other extreme let's do the test is still bad we're already learning something hold on this is the one that is sucking everything in this is everything in so theoretically yeah this isn't gonna be good either well no okay let's start with the bottom okay interesting that's weird the power supply area doesn't have much dust no it doesn't because the air is blowing out of here getting filtered and then being sucked into here there's two fans like hold on there's one two three four five fans worth of pressure going out of here this effectively has a skirt around oh yeah okay so there's dust on this but it's not on the inside it's on the top yeah it's definitely on the top that's so weird okay power supply is completely clean yeah how interesting that is interesting see we are learning things I did not see this one coming that is okay that's cooler than I expected I will definitely give it that well I want to see the Franco good it's filtering stuff this is telling us that this case is intake system is like not that great because these are about as dust this is the other one this stuff is on the outside cuz that's pulling through that makes sense oh just like wow way when you did that like and it's loose which is interesting so our graphics card has no doubt that's a little more than earlier than last time definitely more dust just lying CPU okay there's also definitely more dust on the back Ben C female office so GPU is a little bit better but our supply is better this case does not have filters on the top of the back so you don't get to experience so the main takeaway from this one is that more airflow right around an area is gonna give you a much much higher concentration of dust and that again poor planning is ultimately what's gonna kill you yeah is the graphics card better or worse on this one oh it's waivers way worse so the GPU over there had to breathe in through this which was very apparent yeah and it breathed in junkie dusty yeah that's right this one is actually breathing good air but that's the only piece and the tars busting I wouldn't have thought that having a filtered fan like blowing towards the graphics card would affect the movement of the air inside like the currents inside enough to be the difference okay so this is sort of the like the recommended way so it's neither one extreme nor the other most people would go with a setup similar to this so it's important to note that even though we've actually got four fans pulling in and two going out the ones coming in are filtered so these filtered ones coming in should have much less airflow than the non-filtered ones going out so right off the bat our CPU is pretty good I would say almost us Wow almost as good but not quite there is still no not quite at all there's definitely still noticeable dust and that one was like actually clean so this one what's interesting is that even though it's using a poor method of keeping dust out of your system what it does do is it focuses all the dusts that it does pull in on the bottom and then sucked it all through that filter for this particular case and here a bit yeah and it's gonna change with every case okay should we have a look at the filters yeah okay so as expected this one doesn't have an air curtain around it so the power supply does draw air through the filter filter didn't even stop everything don't filter didn't stop everything at all and there's a lot of customers this is easily the most concentrated wow there's like hairs there's like strands oh okay there's a little bit of that on any yeah that makes sense because these are pulling in right yeah yeah and like it plumed okay so that's as expected so no dust bunny in the GPU CPU fan mostly cleared this one had more fans and got slightly more total dust which kind of makes sense and the filters are slightly more clogged which makes sense but overall I'd say it's probably more balanced the CPU got hit but not as hard as it did on the really bad CPU case yeah but not as good as it did the other time as well that much is this one yeah the in turn so it ended up being in between which it's kind of what we were aiming for we just didn't know is actually gonna work that way here you go then the main takeaways are on your intake fans you want to have filtered air to the greatest degree possible and the more air flow you have the more dusty buildup you are ultimately going to have yeah I think a balanced approach is good but you're gonna have to think about your particular case your particular like if you're on the floor then one of the big things we learned is you want a bunch of exhaust on the floor yeah to keep dust away from your system it actually works yeah yeah and then the other big takeaway is that fresh books is the small business accounting solution for well small

that was actually more enlightening than I thought I'm surprised I thought they were just all gonna be butchered because of the construction zone so guys if you just like this video then like come on we finally did it you were all asking for it but if you liked it hit like get subscribed maybe consider checking out where to buy the stuff we featured we've got our merch store linked in the video description and our community forum which you should totally join for those of you going hey Luke's back where did Luke go he's working on floatplane yeah clean win-win is this video coming out there might be the Alpha yeah or not see ya bye
