I'm going to run a freaking benchmark for an entire year that'll make another video a year from now explaining what the results were of said benchmark why well because we love multi-part videos making you wait for their conclusion no no no seriously this time there is a good reason we've been saying for a long time that balanced airflow leaning on the side of positive internal pressure is better than very positive or any form of negative but we've never done a formal long term investigation and to our knowledge neither has anyone else so let's fix that verdaguer zerg anomic s and plus line gaming chairs make a great addition to any gaming setup check them out of the link below okay first we need to actually establish what the different types of internal air pressure are first you've got negative air pressure this is when the majority of the fan power in your case is focused on sucking air out of said case like if you had a rear fan a top mounted AIO cooler blowing air up and a single front intake then you've got positive air pressure this is where the majority of your fan power is focused on pulling air into the case if you flipped around the fans on your radiator from the previous example it would become positive and finally we've got the mystical balanced or neutral airflow where your airflow in and out of the case equal each other the conventional wisdom goes like so a negative pressure setup will end up pulling air into the case through small gaps in the chassis that are just unavoidable unless case manufacturers use some type of seal everywhere that to different parts of the case met like your side panels to the case for instance this would completely destroy the usability of the case because of air flowing through these inevitable gaps dust is also sucked in and accumulates throughout your rig potentially reducing cooling performance or even causing component failure if left long enough easy solution right with a positive air pressure setup you'll be pushing air out of those cracks instead but if you overdo your positivity it's going to be really turbulent inside of the case you might end up creating pockets of hot air that actually harm your cooling efficiency and besides no cases that I'm aware of are designed to have an intake on every single fan mount so perhaps the more balanced approach is the answer now we here at the office have always rooted for balanced airflow leaning slightly on the positive side of things because theoretically and from our anecdotal experience we found that it's a good balance between cooling performance overall dust reduction and actually being able to control the delivery of cool air to the zones in your PC that need it the most like just under your graphics card and through your CPU cooler but anecdotal evidence has never been enough for us here or at least it shouldn't be so the test today is to build three identical computers one each to represent negative pressure very positive pressure and mostly neutral but leaning on the side of positive since practically speaking it's impossible to make a perfectly neutral airflow setup okay so I've gathered three sets of the same hardware this is mostly mostly some older stuff that we can actually do without for about a year I've got three fractal design our fives and we're going to put it all in these different cases shove it somewhere in the warehouse and then be good to go so let's build so now that that's all done we were left with Audi the case that I built and I had Tyler replicate it twice for any and in between ii any has all of the fans blowing in the two in the front blowing this way the two in the top blowing down and the one in the back blowing in as well now the two of the top blowing down and the two in the front blowing in are actually very realistic the one in the back blowing in is a little bit less realistic but we just wanted to go hardcore with the theme od has all of the fans blowing out so the two in the front are blowing out the two in the top are blowing out and the one in the back is blowing out and then in between II is a little bit different we have the two in the front blowing in and two in the bottom blowing in and then one in the top blowing out and one in the back blowing out the reason why we did this was because the two in the front have to fight with this front panel which is actually a lot of restriction and can only bring in air through the side and then it has to go through a filter a lot of restriction the bottom has to fight with the fact that it's against the ground and has to go through a filter as well so we wanted to kind of overpower the amount of air coming in because it had to fight against these elements and then the air going out was just fan grills no filters or obstructions or anything like that so we only had two of those fans a little bit of a different configuration but should be fine now all we have to do is take these three computers and shove them way back there all right so we're somewhere that you don't normally and Linus tech tips videos this is behind one of the sets about the computers lined up OD any in between e are all in a row so after a year we're going to check how much dust has accumulated in each setup I have arranged them in a way that they should have a minimum amount of backwash to each other they're facing the fuzzy wall so there's no direct intakes this way because the intakes on the front of the case actually come out of the sides of the case so they're in taking from this way and then they're shooting air back out or in the case of any pulling air in from the wooden wall so that should all be fine and this is where I'm going to leave them so now I guess we just turn them on that one worked that one worked that one worked and then we wait a year Braintree is code for easy online payments if you're building a mobile app and searching for a simple payment solution check out Braintree with the Vita zero SDK which is one small snippet of said code you're all set up in less than 10 minutes and they have support staff ready to walk you through the process over the phone if you need them their code supports Android iOS and JavaScript clients and I have SDKs in seven different programming languages they make it easy to offer multiple mobile payment types including PayPal Apple pay Bitcoin venmo Android pay credit cards and more all with just one single integration to learn more head over to Braintree payments comm slash Linus if you liked this video like it if you dislike this video dislike it get subscribed check out the description down below where you can see where to buy some stuff you saw in this video or a Linus tech tips t-shirt which I'm totally wearing right now I probably screwed up the mic sorry about that check out this video which is a workshop video where we explore how cable management and keeping things unobstructed in your case isn't that important anymore but you should probably still Caleb major cables anyways I'll see you guys next time
