Instructor: In this lesson,
we are going to talk about cooling options
inside your BIOS and UEFI.
Now I know this sounds a little weird
to be talking about cooling inside the BIOS and UEFI,
but again, your BIOS and UEFI
can control pretty much everything
that your motherboard has, including its fans.
So one of the things you're going to see inside
of your BIOS or UEFI is the ability to configure your fans
and how they're going to operate.
This includes both your case fans,
as well as your processor fan.
When you look at your fans,
there's going to be some basic settings
that you're going to be able to do,
including setting up either quiet mode,
balance mode or cool mode.
Now when you're using quiet mode,
this is going to reduce your fan speed
and allows higher temperatures to occur,
but this will make it quieter for your overall system.
Now I wouldn't recommend doing this a lot,
especially if you have a high performance system,
because you could overheat your components
if you're running it in quieter mode all the time,
but it is a consideration and something you may do
if you're using a low power system
that doesn't generate nearly as much heat.
Another setting we have is known as balance mode
and balance mode is pretty much the normal setting
on most computers by default.
Essentially, this is a good mixture
and being a balance between working your fans
very hard to keep your temperatures down
and working your fans less to keep your system quiet
even though there might be higher temperatures.
Balance is essentially the normal operation
for your fans running at normal speeds
trying to maintain normal system temperatures.
And then we have cool mode.
In cool mode, we're going to be able to run our fans harder
and faster to create more airflow.
This will be noisier,
but it will get temperatures lower inside of your system.
This is very useful
if you're going to be overclocking your processor
because when you overclock a processor,
you will generate excess heat,
and so, putting your fans into cool mode
can help dissipate all that extra heat for you.
Now in addition to these three basic modes
of quiet, balanced and cool,
you may also have options
for things like fanless or custom.
Now fanless mode means you're telling your motherboard
you're not going to be turning the fans at all.
You wouldn't want to do this normally
unless you've replaced your fans and cooling system
with something like a liquid cooled variant,
in which case,
the motherboard won't be controlling the fans,
and instead, you'll be using the liquid cooling system
to be able to cool down your system.
The other option there is custom
and custom allows you to go outside
of the three pre-configured sets
of quiet, balanced and cool and create your own.
So maybe you want it to be a little bit more than balanced
but less than cool.
This would allow you to do that
by creating a custom setting of your own.
Now in addition to saying these basic settings and profiles,
some systems will allow you to get very specific
in your fan settings,
including how much power you're going to send to each fan
and how fast you want those fans to spin in terms of RPMs.
If you have a system that supports this,
you can really get customized
with how fast you want those fans to run
or you can configure it based on temperature.
That's right, your motherboard also has
some temperature sensors that are built in
and this allows you to figure out how hot the processor is
or how hot the motherboard is
and then run your fans based on that
to keep a consistent temperature.
So for example, once you set the temperature
to a certain level,
if the temperature starts rising in the case,
the fans will speed up
to be able to bring that temperature back down
by getting that heat dissipated out of the system.
On the other hand,
if the temperature is lower than your set point,
it will actually turn off or slow down the fans
so it'll allow the system to rise in temperature
and that will reduce your amount of power being consumed
by the fans, as well as the amount of air flow and noise
that is being generated by them as well.
So keep this in mind when you're dealing
with your BIOS and UEFI.
You have the ability to see your fans
and what they're doing in the system,
as well as configuring how you want them to operate.
