when it comes to cooling down a PC many enthusiasts and Gamers want to make sure
that they've got some serious flow going on and no of course I'm not talking
about your questionable hairstyle but about airflow but unlike buying say uh
ceiling fan picking the biggest fastest
spinning computer fan you can find is not always the best solution don't get
me wrong fan sizes and RPMs how fast
they SP are important but an element of
fan design often overlooked by novice Builders is whether the fan is optimized
for high air flow or high static
pressure but what does that mean I mean can't any fan provide decent air flow if
it spins fast enough well actually different fan blades are engineered to
move air in different ways fans marked
High airflow have one objective in mind to move as much air as POS possible
through an open opening you might see
the marketing for a high a flow fan focus on its CFM rating which stands for
cubic feet per minute since a cubic foot is a measure of volume then this is
indicative of the actual amount of air that the fan can either intake or
exhaust or I mean if you think about it they're both going to be about the same
on the other side of the coin are high static pressure fans static pressure is
actually a concept in in fluid dynamics but don't worry too much you don't need
a degree in physics to understand how this relates to cooling down your rig
simply put High static pressure fans are better at forcing air harder through
small spaces they may not move the same
volume of air as a high air flow fan if
they were both in sitting on a desk with nothing to push through but they
typically blow air a little bit of air
more strongly so when exactly do you want to pick one over the other well as
a general rule high air flow fans are better suited to be used as case fans PC
cases tend to be relatively open inside that is assuming you didn't cram a bunch
of wiring into the front of it or like Snoopy or something meaning that being
able to move lots of air at once can result in more effective cooling by
contrast static pressure fans typically find their homes on things like heat
sinks or Cooling radiators cooling components like these often have lots of
metal fins that are used to increase the surface area of the device that needs to
be cooled and to dissipate heat so to
cool off the heat sink properly air needs to move through these fins with a
sufficient amount of force in this situation to make sure that the amount
of air moving through your heat sink is high enough you've got to have high
static pressure but that doesn't mean
that static pressure fans are a one-trick pony in fact they can often be
a good choice for chassis fans if you've got some kind of an obstruction that
might hinder airf flow otherwise for example many cases have hard drive cages
directly behind the front intake fan so in this situation a static pressure fan
can be more effective at getting the air through these small gaps they can also
be useful if you have a case with very narrow vents on the front or a fan
filter that's designed to filter the dust out of the air but is of course
going to obstruct airf flow since many
radiators and CPU heat sinks come with fans pre-installed it's a good idea to
ensure that they're high static pressure if you want to get the best performance
possible despite the fact that these fans are better for CPU cooling some
manufacturers stick with whatever standard airflow focused fan for
whatever reason to do your homework so you're getting the best performance
possible of of your new cooling solution after all there's nothing quite like the
feeling of seeing your temperature stay low after hours and hours of gaming that
is assuming you didn't build your computer into the side of an
igloo you got a whole other set of issues speaking of
igloo brain tree their code for easy
online payments means if you're building a mobile app and searching for a simple
payment solution you're going to want to check it out I mean the payments API is
an extremely important aspect of any successful app well maybe not a
successful app I mean Flappy Bird was technically a successful app if we look
at it in terms of downloads but if you want to get paid then it's a very good
idea the brain tree v.0 STK is one
amazingly simple integration that gives you every way to pay I mean we're
talking Android pay Apple pay PayPal
venmo credit cards even Bitcoin and if something new pops up brain tree is
going to be figuring out how to support that too they're used by Uber Airbnb and
GitHub so they are scalable and integrating it into your app is as
simple as inserting a few lines of code and if you have trouble they will help
you out by the way so try out the sandbox learn more about brain tree and
