okay so you ask anyone on the internet what's the best thermal compound what's
0:04
the best way to apply it to get a thousand different answers because
0:08
there's everything from garbage like this all the way up to high-end
0:12
compounds full of silver and and diamonds and all kinds of that crap
0:17
but what everybody seems to pretty much agree on is how to remove it
0:23
grab some 99 isopropyl alcohol got like
0:27
tricks slap that on your CPU and bam thermal
0:32
compound's gone but we thought to ourselves you know what
0:36
conventional wisdom's not good enough for us so we got you guys 15 different
0:42
solvents to find out which one truly
0:45
removes thermal compound better than anything else
1:00
the ripjaws km 570 mechanical keyboard from g-skill features full RGB a simple
1:05
design cherry mx switches and more check it out now at the link below
1:10
okay so you're probably thinking to yourself come on Linus the reason we
1:14
don't debate this is we already know the
1:17
best way to remove thermal compound but picture this okay
1:21
it's late at night you got the big match tomorrow you're
1:25
building up your rig you're ready to go except oh
1:29
no there's no solvent it turns out earlier
1:33
in the day little johnny took all the rubbing
1:37
alcohol poured it all over his skinned knee and now you've got nothing left so
1:42
you're rummaging around in the kitchen the pantry the bathroom and you come
1:45
together with a list of stuff that looks
1:49
a little something like this we've got 100
1:52
orange juice we've got beer we've got distilled water goo gone vinegar more
1:58
beer windex hydrogen peroxide absolute
2:02
vodka vodka whatever you know what it is we've got
2:05
nail polish remover alcohol-based hand sanitizer coke isopropyl at 70 and 99
2:12
concentrations and finally arctic silver's fancy expensive arctic
2:18
clean surface preparation and we're going to be testing each of them on the
2:21
two major types of thermal compounds the more runny kind and the more kind of
2:27
particulate kind okay so we're going to start with icy diamond and the
2:32
methodology is pretty simple we take the thermal compound we go
2:37
and with a clean CPU and heatsink we apply the usual grain of rice sized boop
2:42
there you go and slap our nhu 12s cooler on top of it
2:50
once it's screwed in all the way we give it the old wiggle to make sure it's uh
2:54
fully spread out and leave it for a minute or two
2:57
then we take off the cooler you can see how this is gonna get pretty old pretty
3:02
fast and there we have it a dirty CPU
3:05
now the original plan was to take our solvents and kind of
3:10
uh dump them onto the CPU and then we
3:13
realized oh yeah that's uh that's probably gonna make a bit of a mess hold
3:17
on so as a compromise we settled on using the heatsink
3:21
as our test surface with the thermal compound smear covered
3:26
we left each one for 60 to 120 seconds
3:30
to allow the solvent to do its work after the waiting period
3:35
we wiped each one five times without applying too much
3:39
force we're evaluating how well the solvent
3:43
works not how hard we can press down on a
3:46
heatsink then to test we take something very clean very fine
3:51
so a coffee filter in this case
3:55
wipe it off and boom
3:58
that is how we collect our results for each solvent on each type of compound
4:05
okay we are done
4:08
screwdrivers down and we have the results okay most of them
4:12
are not very surprising but some of them are
4:17
basically here's how the grading works if there's anything on the coffee filter
4:23
that's a fail so hydrogen peroxide i was expecting another topical sanitizer to
4:28
do well no not so much beer
4:31
epic fail almost all of it stayed on the
4:34
heatsink windex this one performed
4:39
okay it did leave a significant residue
4:42
though so we'll call that a c minus hand sanitizer so it is an alcohol-based
4:47
sanitizer and this actually performed really well so there's at least one
4:52
household item that would work quite well distilled water was actually
4:57
the worst not good for cleaning off your CPU
5:02
goo gone though excellent result here we've got almost i
5:06
would say nothing on our coffee filter
5:09
arc to clean i mean this is a purpose designed uh cleaner so this one
5:15
performed perfectly as well and nail polish remover
5:19
this one came in really well remember this is an acetone based one though i
5:23
wouldn't expect the same results from a regular one
5:26
vodka okay guys so if you gotta clean
5:30
your CPU with alcohol go with the vodka
5:34
not with the beer here's our isopropyl alcohol i think
5:38
we've put an end once and for all to the debate
5:41
70 versus 99 we're going with doesn't frickin matter
5:46
coke was basically tied with water and
5:49
you get kind of a urine stain looking thing on your uh
5:53
on your paper towel and the same goes with orange juice except even more urine
5:58
finally we've got vinegar which worked actually
6:01
much worse than i expected barely removing any of it and finally the
6:07
golden standard isopropyl 99
6:11
oh that was fun now let's do it all over again with mx4
6:17
here we go wow yep okay the intent was to use a
6:22
thermal compound that's a lot thinner and mission freaking accomplished there
6:26
here we go
6:38
okay
6:49
okay here we go last one
6:52
whoa
6:56
three four
7:00
five wow
7:04
the beer actually performed
7:10
shockingly well with mx4 okay let's get
7:14
all the other results out here and do the whole roundup then so for a thin
7:19
compound like mx4 freaking almost everything
7:24
worked astonishingly okay well that's isopropyl 99 we expected that to work
7:28
but vodka clean vinegar okay we got a couple little
7:33
flecks there but basically clean beer beer worked
7:38
hand sanitizer windex
7:41
everything's got just like you know what we would consider a negligible okay coke
7:46
didn't work especially well but arc to clean absolutely flawless that one looks
7:51
great here nail polish remover perfect
7:55
distilled water sheesh hydrogen peroxide perfect that
8:01
was an epic fail first time around 70 isopropyl looking pretty good
8:05
even orange juice worked what
8:09
leading us to coke which also
8:12
worked so the obvious question here then is what could possibly go wrong while
8:18
removing a thin compound like mx4 and let me show you
8:22
you can pull the CPU out of the socket when you go to lift the heat sink off
8:27
i had just done another mount so that i could
8:36
what is that
8:40
1800x oh terrible okay
8:43
anyway the point is i had done a final one so i could do a live demo of how
8:49
while what we've discovered is that some household agents would work to remove
8:54
thermal compound another perfectly viable method in a pinch is straight up
8:59
elbow grease so here's one two three
9:03
four five of those and a coffee filter
9:11
and there's really not a whole lot left
9:14
so there you have it guys how to remove thermal compound everything from
9:19
super sensible ways all the way to stuff that makes no sense whatsoever and how
9:24
well they all worked thank you for
9:27
watching and please pray for our 1800x
9:36
is always so confusing to me when i'm at the supermarket and i see people
9:40

10:37
description as a summary uh if you're going for thermal compound removal we're
10:42
thinking maybe the isopropyl alcohol or
10:45
the goo gone or arc to clean if you're just like a mad baller and you like to
10:49
you know whatever spend a lot of money on removing thermal compound uh also
10:53
