this is a question I've been asked a
hundred times and based on a quick
google search it looks like there are
quite a few other folks who want the
answer how hot can my pc run before it's
not safe anymore
ok well let's start with why you would
care how hot it run some lots of reasons
high temperatures can cause all kinds of
stuff in semiconductors on it increases
the electrical resistance reducing
efficiency
it can speed up the degradation of
electrical pathways within the component
allowing errors that cause data
corruption and it can even if the proper
safeguards weren't in place cause the
low-temperature solder that is sometimes
used to completely melt
alrighty then that's very scary can you
give me the answer that Linus
now hold on let's start with some
information from the web sites of a
couple of computer hardware
manufacturers you may have heard of the
t junction temperature the point at
which it will turn down its own speed to
preserve its life for the intel core i7
4770k cpu is a hundred and five degrees
Celsius the out-of-the-box standard
operating temperature of 95 degrees
Celsius for amd's r9 290x graphics card
is to quote AMD perfectly safe while
powered on a WD red hard drive can
operate it anywhere from zero to 70
degrees which in their testing produces
no unrecoverable error and a gtx 780ti
ships had an 80-degree maximum and
nvidia theoretically allows up to 95
degrees but we found that they actually
limited to around 86 degrees Celsius
so those are super scary high
temperatures Linus
my friend said it should be lower are
they miss informed if it says it's okay
directly on the manufacturers website
why is there so much confusion out there
about this because it's not quite that
simple
unlike the engine in your car which uses
a thermostat to maintain itself within a
very narrow range usually with between
ninety to a hundred degrees Celsius most
pc parts don't have moving parts that
rely on tight manufacturing tolerances
and high-performance lubricants to keep
them functioning so don't they don't
really have an optimal operating
temperature that means that while the
hard drive with moving parts specified a
maximum temperature for the other stuff
a maximum
is specified in a minimum is not because
you can pretty much run it as low as you
want and it will be happier than a pig
and split with that said lower is better
if you're taking the appropriate
precautions for most people you're not
going to want your temperatures to drop
any lower than ambient or the
temperature of the surrounding air
because below that temperature water
droplets forming on your components due
to condensation becomes a major concern
water is worse for your hardware than
high temperatures
so here's the summary first check out
the manufacturers product page then take
that information with a grain of salt
if you're one of those people who
believes in taking really good care of
your stuff and you want to be sure that
your hardware will last and be reliable
keep in mind that the way manufacturers
right there products is based on the way
they expect most people will actually
use them they're not expecting you to
still be using that cpu graphics card or
hard drive in 10 years time and they
certainly aren't giving you a warranty
that last that long
so they build some buffer into the
numbers but they don't worry about those
fringe cases too much
so for added assurance take bear number
and building your own buffer that makes
you feel comfortable speaking of fringe
cases the people who think trekking to
the store and finding the last employee
who actually still works on the sales
floor of a grocery and drive chain to
unlock a cage so you can spend twenty
dollars on a package of freaking razors
only to burn through them and realize
that now you have to do it all over
again
the preceding run-on sentence was

below and enjoy the convenience of
savings of the King great razors and
blades that they delivered straight to
your door once a month with the
precision of a clean-cut
machete-wielding man during a box that
would have presumably in a bear costume
but could also be a bear who ate a
person and they took over control of the
bear from the inside and applied for a
job at a pretty cool company that
shipped bathroom supplies to their
thousands of customers who
ok sorry I got a little distracted there
anyway your first order contains the
handle that you'll need for the rest of
your subscription
and the rates are under ten dollars a
month for even their most luxurious
shaving experience the executive if that
sounds great head on over there and tell
them I sent you
oh and don't forget to check out there
shave butter and one wipe Charlies as
well the shea butter is for your face
it smells really nice the one wipe
Charlies are for your butt and they
smell nice too
