so you got this computer that you got to cool this looks like a fairly simple
problem to solve right I mean Intel doesn't even include copper slugs in the
middle of their hunk of aluminum heat sinks anymore so why is it then that we
pay actual money to cool our processors
I mean in the case of the stock one I guess you don't really pay for it it
comes in the Box for nothing but maybe you broke it or something so today's
mission is to build our own cooling heat
sink I by power and MSI's new lineup of
gaming laptops feature Intel's 7th generation core i7 processors check them
out at the link below so with the
mission of creating our very own lonus Tech tips heatsink I set off for a disc
discussion with the lonus Media Group engineering and stuffed animal Taxidermy
division they went away for a couple of days and then returned proudly producing
a hacksaw a block of aluminum and a
stack of papers full of pictures of Elon Musk
over which in crayon it said just raw
Dogg it at which point I really began to wonder what exactly it is that I paid
these people for and got to work I
guess so the basic principle of an aluminum heat sink is actually pretty
straightforward you've got this little heat generating doodad right here and
you need to take that heat and you've got to spread it out then you've got to
dissipate it to the air so what you need is a thermally conductive material so
the engineering department did manage to get that far we've got a hunk of
aluminum which has excellent thermal conductivity and then what you need is
you have to increase its surface area so if all we did was take this and stick it
on top of a CPU what we'd effectively do is we would
spread the heat but we would spread it throughout this block without actually
achieving any of our cooling goals so
once we've got this spreading the heat we've got to increase the surface area
and the way that apparently they intend for me to do that I mean at least they
have the decency to get a fresh blade for the hacksaw is to throw the Block in the
Vie and just start sawing out fins I've
been informed that this is the good one whatever that means so we're going to do
a practice cut on this other hunk of aluminum see just how accurate we can
get here the more fins and the thinner
the
better okay unless we have all the time
in the world and we assign absolutely zero value to
it that's clearly not a way to go about it so back to the engineering
department they brainstormed and came up with a new solution let's ARM lonus with
power tools so I've never used a reciprocating
saw boom and it's plugged in but it
looks really fun so
uh Safety First kids exciting WD40 on here
wow we made as much progress in like 4
seconds as we did
before okay that's not so hard let's do
the real thing see here's my like 10 minutes of hack sawing there's my like
10 seconds of uh reciprocal sawing okay
screw it yeah
okay how many blades did you say we
have unplugged to change the
blade have a lot more respect for what Cooler Master
does I think that what we really need is like a constant flow of WD40
almost we are definitely making faster
progress now so not having not trying to cut the entire thing at once keeps the
blade from uh getting so gunked up with
metal got to be really careful we only have one blade
left almost there just got to finish up one last one so we found that this stuff
uh fluid film actually does a better job
of lubricating the blade which would have been great to know cuz it's just
generally a lot less nasty than
WD40 that's the stuff that smells by the way
almost
there holy crap I think the only thing
more epic than the DIY heat sink we've
created is the mess that we've created I
mean this is like I don't know if it's
like a pound of aluminum but boy howdy is it ever a lot of aluminum I guess we
better clean this up look at this oh there's WD40 all over it this stuff is
hard to pick up okay we are actually getting pretty
close to being ready to try out mounting
this baby after a little bit of washing
and a little bit of filing just to take some of the really rough edges off of it
so we don't hurt ourselves while we're working on it we are going to devise
some kind of mounting system now that's the kind of of thing that you're
probably thinking to yourself ginus surely you guys thought of that before
you started to which I would
reply it can't be that bad right yes my
friends it's zip tie time again so we're
going to throw on our usual icy Diamond thermal
compound we are going to plunk that bad boy down on there and we are going to
figure out how to zip tie it on you know
what let's get some hot glue going on here too a Linus Tech tips project is
truly not complete without hot
glue so in terms of mounting for this
puppy we're just going to kind of just going to kind of YOLO it I mean were you
really expecting anything
else there we go
okay so the hot glue fan is on if we ran
through the holes on the fan it was Albert Einstein who said that there's a
fine line between idiot and
genius comments are going to be full of he said no such
thing what the
crap what kind of cheap ass zip tie
breaks just like that where do we get these oh they're generic so this is it
Moment of Truth time well posts that's a
good sign CPU temperature sitting at 25
degrees we've got idol loaded up let's get our sensors going here idle
temperature not bad and it's not like
the fan is working really hard either check this out check this
out it's just barely spinning see that
so let's go ahead and hit it with a
stress test CPU package is sitting at 74°
but I think we've leveled off
success for $3 worth of
aluminum and a fan that we found some
old 80mm Silverstone fan we were able
to okay hold on a minute so it's been running for about 8 minutes now and the
Victory is less complete than we at
first thought so there's some good stuff to take away here we're still running
above the base speed of the i76700 K but
we are not turbo boosting to the max anymore so you can see we're actually
getting some CPU throttling and overheating detected here our CPU
package is up around 98° C and uh if you
put your hands on the heat sink it is pretty toasty but the
computer doesn't turn off it does
run so there you we have it we did what we set out to do we made our own heat
sink is it as good as the one that Intel puts in the Box no but Intel doesn't put
a heat sink in the Box for their unlocked K series processors anymore so
this if you have an unlimited amount of time and enough money to buy literally a
power tool just to make it but for some reason not enough money to just buy a
heat sink okay we don't know what the point of it was but it was fun wasn't it
even the name VPN makes browsing the internet privately and in a more open
manner sound kind of like techy and difficult but with TunnelBear it is so
easy they've got applications for Android iOS Mac PC even a Chrome
extension and it makes it as simple as pressing one button and then boom your
connection gets encrypted with aes2 56-bit encryption and oh by the way
tunnel bear does not log any of your activity and it changes up the location
that you appear to be browsing the internet from so online websites and
services will think you're someone else from somewhere else but don't take my
word for it you guys can try it out for nothing by heading over to Tunnel
bear.com LT where when you sign up for an
unlimited account you can save 10% woo
