Fan placement is an important constituent in your system ’s cooling . The quantity , positioning , and orientation of devotee affects overall organization performance , dissonance levels , and how often you need to clean your whole system out . Although you are n’t going to see a spectacular conflict in your PC ’s performance from adding one more devotee , or making trusted they ’re pushing rather of extract ( or frailty versa ) , it ’s still useful to optimize this part of your PC ’s cooling to get the best experience for you , the PC user .
So , whether you ’re looking to boost your system ’s cooling toimprove your overclock , or want to keep your lover pep pill as humbled as potential without overheat , here ’s a guide to microcomputer airflow , as well as some suggestions on fan placement and position that you might find utilitarian .

Get the basics down
One of the great sin of some budget prebuilt personal computer is that they only come with a single rooter . Often , it ’s an exhaust fan , which is fine , but that does n’t help much cool atmosphere get into the system of rules , and it is unconvincing to get all the hot atmosphere out once you start doing something ask . That could well conduce to some thermal throttling , and ( as we ’ll talk about more below ) negatively charged pressure is not ideal if you do n’t want to have to clear out debris from all the nook and crannies every six month .
If you want to just check that you have the rank bedrock that any personal computer should have , then you need to have at least one fumes devotee and one inspiration buff . Ideally , the intake fan should be slightly more sinewy to insure you have positive force per unit area , but that ’s not as big a headache as just making certain you havesomecool air being pushed or deplume into your PC , and another fan stuff the hot atmosphere back out again .
Diminishing returns
Do you want considerably cool off execution for your PC?Upgrade the processor tank first , and upgrade the GPU cooler if you’re able to ( or buy a good nontextual matter card with a better cooler ) . If you ’ve done that already and want to improve operation , just add more rooter . Or honorable lover . But to be very decipherable , there are diminishing returns . A third intake fan is not going to meliorate performance by more than a degree or two over the two you already have . Converting anAIO radiatorto have a get-up-and-go / pull shape with fans on either side might shave off a mates of degrees , but is that deserving the money you ’d have to expend on it ?
promote your cooling if it ’s currently unimpressive , but keep your expected value in impediment , and watch your budget . It might be better spent elsewhere .
Heat rises
Most PC caseshave intake fans mounted on the front , and one or more fans get on on the back to exhaust the warmth . But heat rises , which means you ’ll typically find the greatest air temperature at the top of your pillow slip . Placing your fumes fan in the roof can help get rid of spicy air faster than if they ’re at the fundament .
The dispute is n’t striking , but if you ’re look to min - max , do n’t bury what heat likes to do when it is n’t being force and attract around .
Positive pressure is key
If you hatecleaning out your PC(and who does n’t ? ) , then make trusted it is running with positive pressure sensation . That is , there is more air being push or pulled into the case , than labour out of it . That means that any nook , blowhole , holes , or gaps in panel work will have that extra atmosphere forced out of them . That keeps all the air going into your showcase moving through the dust filters at the front or underside . In a negative pressure scenario , where there is more air being promote out than pulled in , you get melodic phrase pulled in through all those holes and crannies , leading to unwanted dust buildup .
Technically , from a performance perspective , it ’s more significant to get free of the blistering air than it is to pump more coolheaded air in to the case , but the difference is n’t dramatic — specially if you have a robust exhaust system already . see to it you are only getting international air in through a detritus filter is more important for long - condition organisation health .
Direct cooling helps
scheme temperature reduction does n’t make a massive difference to factor temperature once you have the fundamental principle down , but you’re able to see some positively charged resultant role if you blow cool air directly onto the components you want to cool . If you have intake release in the root of your case or in the side gore , placing fans there that louse up cool air straight onto the graphics card will help lower its temperature .
Depending on constituent placement and the size of it of your case , this may not be viable for the central processor cooler , but if you could get a fan that crusade coolheaded outside air decent on to a factor you want to run cooler , it will have an essence .
Push is typically better than pull
Push versus pull is a long - running public debate when it comes to microcomputer cooling . “ Pushing ” is where the lover is mounted in front of the component or coolheaded and drives the air into it , while “ draw , ” is where the fan is mounted on the can of the component or cooler and draws the air through the cooling fins before reach out to the sports fan . Though you will see slightly better temperatures with a rooter jump on in push button and another rise in twist , there ’s very trivial difference between push and pull configurations in closing off .
However , with a push fan orientation , you’re able to rest assured that it is fight the melodic phrase from where you want it and into or across the component / cooling fin . With a pull conformation , it ’s potential that the breeze will be drawn from somewhere else , depend on component or cooler arrangement , which may not be as ideal .
Watch out for turbulence
This one is tidyingthan it is about rooter placement , but recognise this : If there is something in the way of your flow of air , it will generate some disturbance , and it will trim the effectiveness of the cooling . It wo n’t be by much , but just as direct cooling can make a divergence , a fan that has a clear runway to blow cool melodic line into a type and to the hot components will be more effectual than one that is blowing directly into a mess of cables .
Again , there ’s diminishing counter here , but tidy away overseas telegram and placing fan where they are n’t impeded in their problem will allow them to sour better , leading to dependable carrying out and down in the mouth temperatures .
