let me tell you guys I have seen some crazy stuff on that internet which no no
no not that or oh sorry I misunderstood
yeah yeah like that gaming or workstation computers with multiple
processors be they CPUs or gpus have become more common in recent years and
how to keep them cool the advantages of which we cover here is an incredibly hot
topic for obvious reasons now the heat generating components in your system are
going to have heat sinks attached to them you can learn more about these here
and here and why we need them but the main thing you need to know for this
video is that unless you start getting into some pretty exotic stuff the way
all that heat generating componentry stays within its rated operating
temperature is by dissipating waste heat
to the surrounding air the trick here is that heat transfer relies on two main
things for best Effectiveness a lower ambient temperature so how hot the air
around the heat sink is and more air movement the first one's a bit tricky
living somewhere cool or using air conditioning helps a lot but because
most electronics are surrounded by some kind of box the air being used to cool
them can be considerably hotter than the rest of the room hurting cooling
efficiency not to mention that the room itself can begin to heat up during heavy
use I mean we could just pull all that
stuff away but I guess running your electronics unprotected can have
unforeseen consequences and even if we don't want to go overboard and head
outside although I heard it has great graphics indoors you'll find plenty of
other hazards too like pets and children
so I guess we're stuck using enclosures to keep our expensive stuff safe so
let's focus on strategy number two make the air move fast by adding fans but
that has some drawbacks too there's noise but also one that's potentially
more problematic a silent killer all around us dust dust clogs the fins of
heat sinks reducing their effectiveness gunks up the moving parts of fans
reducing their effectiveness and is just plain gross and adding more air flow
adds more potential for dust to accumulate unless you do it responsibly
so how do you practice safe cooling
balanced air flow fans can be configured in one of two ways intake pulling air
into the case or exhaust pushing it out but the internet is full of debate about
the merits of having more of one or more of the other so let's put it to rest if
you had all your fans pushing air out first they'll all be working against
each other reducing each other's efficiency and second because fans move
air rather than creating it they have to get the air they're exhausting from
somewhere so the internal air pressure will be negative relative to the room
and the case will pull air in through nooks and crannies where dust can
accumulate and also be pulled in the other way around trying to inflate your
computer like a balloon by having everything as an intake has the same
problem with the fans working against each other but the advantage of blowing
air out of the small holes in the case
to prevent dust from entering there but of course that doesn't help if you're
not filtering the dust out of the air that's being pushed into the case by a
fan so that my friends is the ultimate
solution a reasonably balanced airflow
scheme that leans on the side of positive internal pressure so you're not
canceling out any of the work that's being done with filters on the intakes
so that you don't have excess dust coming in and don't worry if you can't
afford filters used panty hose works great something to note here is that
surprisingly the conventional wisdom of hot air rises actually has very little
impact on any of this so the most important takeaway is balance if you
don't have a fancy smoke machine like the one Silverstone uses to test their
cases just watch in the longer term for dust accumulation in areas like mesh
panels and areas around optical drive bays and if you're starting to see that
in spite of your filtered intakes it might be time to adjust the ratio of
intake to exhaust for your system speaking of systems sort of
