thinking about building your own pc but worried that it's going to be as tricky
as luke skywalker's mission down the death star trench well fear not you may
not have the spirit of obi-wan guiding you as you plug wires into headers not
much bigger than a womp rat but you do have episode four of avoiding common pc
building traps which i hope will give you some
new hope first off while the empire made a huge
mistake in connecting the thermal exhaust port to the main reactor in your
case you want waste heat to exit your computer as directly as possible which
is why you should pay close attention to fan orientation
specifically if you're using more than two fans it's a good idea to create
positive air pressure inside your case by using slightly more fans as intakes
rather than exhaust this will force air out of your case
more effectively reducing dust buildup as long as your case is filtered and it
also potentially allows you to run your fans at lower speeds for a quieter
computing experience otherwise having the same number of
intakes and exhausts preferably with the ladder more towards the top rear of the
case since heat rises is a good safe bet
you can learn more about fan configuration and air pressure up here
and while we're on the topic of thermals are you using a tower style air cooler
for your CPU if so watch your hands while you're installing
it or working anywhere near it such as if you're trying to insert a graphics
card below it these air coolers use a lot of little fins to maximize the
surface area that's available to cool down your processor but to achieve this
the fins are often super thin meaning they can also be super sharp and you do
not want monochromatic blood harshing your
RGB vibes but let's say you've decided not to bother with that and you go
straight to water cooling specifically a custom loop you can learn much more
about custom water loops in this video one common trap for folks who are just
beginning with liquid cooling though is that they might buy components made of
different kinds of metal you see if you buy for example a copper
CPU block but an aluminum radiator and
put them in the same loop they'll eventually corrode due to chemical
reactions that occur when you mix metals
not only destroying your loop but also possibly your expensive electronics if
water leaks out yikes leading us to a boring but incredibly
important tip it seems like every other day we see a build with big money spent
on expensive components of questionable utility
and unlike our advice from the last episode to
balance the build by avoiding doing things like pairing a 50 CPU with a 500
graphics card some things are just colossal wastes of
money regardless of how high-end the rest of your rig is like
hard drive water blocks 300 sound cards
at that point you should really just be getting an external dac and amp and
gaming network cards which are little more than snake oil unless of course you
really just want the thing for aesthetics finally no matter what kinds of exotic
components you are or aren't using consider initially building your system
outside of the case not only does this save you from the hassle of taking
everything out if you have to troubleshoot a bad component it also
allows you to more quickly isolate the defective part if your system won't boot
so do you have any sage advice for new or veteran pc builders leave it in the
comments below and also let us know if you'd like us to continue the avoiding
common pc building traps series
or if it's time for it to become one with the force
yeah we had to sneak that last star wars reference in there and we also need a
