Common Fan Layout Mistakes You Might be Making with Your PC Build! PC airflow tips and tricks

this is the provoked prawn and in this video I want to talk to you about how to install PC fans and more importantly how not to install them as I've done here and this is really easy to do because a lot of modern PC fans have an aesthetic to them which makes them pleasurable to put in certain directions the back of the fan often has struts and wires on it it doesn't look nice in the front obviously has a much nicer looking aesthetic so it's far too easy to install fans in a certain direction just for the aesthetic purposes and I've made mistakes in the past as you can see with the Corsair crystals 680x here where I installed fans purposely the wrong way around for the view of the RGB it's obviously potentially has a negative impact on performance so I want to talk about the basic logic of fan setup how fans work and more importantly where to install them for the best performance and the best airflow in this demo video I'm going to be showing you some noctua fans but it will work with other fans as well the logic is basically the same from fan to Fan so you obviously have an airflow logic to fans where they suck air from One Direction and push it in another the usual case in most cases and this is 99.99 recurring of fan setups is that the airflow is simply from front to back so the front of the fan pulls the air through and then it's pushed out of the back so if you're trying to suck air you need to put it so that the front faces the direction you want to suck it from and the rear blows out you can see me trying to demo this here with a bit of card or essentially the rear of this fan should be blowing and then the front is sucking because the card will get stuck to it and I'll demo this a bit more successfully later on but essentially so you need to just set it up with this sort of logic applied you also need to think about other things so for example not putting fans in close proximity where they'll be fighting each other so you can see I've got a fan facing one way and another fan facing a completely different way there and they're obviously going to impact each other now there are usually arrows on the fan housing that you can see here for example which shows you the flow of airflow so if you're not quite sure based on what I've been saying you can see how that's going to work and here I'm running some smoke through some Corsair fans just to demonstrate this effect so you can see that was pulling air through with the front facing it and now with the rear you can see the smokes being blown away and then again sucked through if you face it in the right direction so I'll apply some more of that logic later on now what I've done is I've taken the Leon Lee Dynamic air case and I have stripped it out completely from my previous build and rebuilding it just for the purposes of this video I am intentionally installing fans in the wrong direction so this is not meant to be a perfect build it is a demo on what not to do so here I'm setting up the fans on the radiator which is mounted to the side or back of the case depending of you and I'm setting them up so they'll be pulling cold air in from the rear so pulling kale there in from the rear of the case through the radiator to cool that down actually I have tested both directions with this and I'd suggest it isn't a problem either way depending on the logic of the case this might work quite well actually because you're basically calling the rad down and sort of drawing warm air into the case but there are some other considerations now what I'm doing is I'm front mounting some fans and these are the little wrong way around again so usually with front mounted fans you want to install them so they pull cold air into the case and basically then blows that across the your GPU and your motherboard and then exhaust out of the top and the rear but I'm doing completely the wrong logic here because I've installed intake fans on the top and then exhaust fans on the bottom and the front and I basically have it set up so that it's pulling air in from wrong directions and blowing it out in other ways so here we've got basically cold air is being sucked in through the radiator but it's then being blown out immediately by the front fans and the bottom fans and the top fans are set to intake now naturally hot air rises so you want to try and follow that logic so essentially you don't want to do this you can see that I've got exhaust on the front and the bottom and then intake on the side and top logic says that that way I'm now trying to force the hot air that's Rising downwards and also the cold air that could potentially be pulled in out and so I'm basically fighting the logic of how physics works and essentially making life a bit more difficult I am however 10 essentially pulling air from above the case onto the RAM and onto the CPU Cooler so it could still work in some ways but this is not optimal so this is not the way to do it this performance won't be as good as it could be because heat is naturally going to rise from the CPU from the motherboard from the RAM and from the GPU as you'll see in a minute and so we're fighting all of that logic and the fans will have to work harder for it now if I set the smoke machine up at the front of the case and try and blow air into it imagine that this is cold air trying to go into your case you can see the front of the case is now blowing that cold air away from the machine and the bottom fans are also doing the same so rather than sucking cold air up into the bottom is being blown away so that is obviously not ideal now you wouldn't want smoke going into your PC but you would want air going in there and now it isn't once I've got the GPU mounted there's basically no cold air blowing onto it from below or from the front which is not do because most gpus operate with the fans below pulling it onto them and then exhausting it out of the rear where the connectivity ports are you can see that in this setup I do have some intake but it's basically the opposite way around to what it should be and no matter what direction you try and send the air in or in this case the smoke is getting blown away from the components that need the cooling also in this position with this setup I am essentially making a GPU and the case fans fight each other so the graphics card fans are trying to suck cold air in but the fans on the bottom are also sucking it out so essentially they're going in the wrong direction so the hot air is rising in being sucked up but also is getting uh for flowing in the wrong directions and it's completely illogical and doesn't make any sense so the end result is a case that theoretically looks okay at a glance because all the fans are certainly spinning although the cables are a mess but I've done that sneakers don't plan on leaving it like this but it obviously isn't going to work very well so don't do this make sure you've got the right logic front fans set to intake bottom fan set to intake exhaust fans on the top and the rear you've made it right to the end of the video you brilliant Legend you if you've enjoyed it click that
