liquid metal it's a hell of a drug you know
0:03
first you delid your CPU and then that
0:07
high wears off so then you like liquid metal your laptop and again you're
0:12
rewarded with amazing temps and even a performance boost and that keeps you
0:17
going for another week or so and then
0:20
you notice something getting kind of hot in your pants
0:24
you know the idea it starts small but then it grows and grows getting more and
0:29
more solid what if you could make your phone
0:34
run cooler and faster with liquid metal
0:38
well guess what that's a super risky maybe even bad idea
0:43
so we're going to show you how to do it after we tell you today's video is
0:47
brought to you by shade tree sunglasses shade tree sunglasses are handmade from
0:52
hardwood materials featuring polarized lenses a variety of designs and even
0:56
cool new carbon frames get 10 off your next order through our link below
1:10
so it is common for phone performance to
1:13
nosedive during any workload that takes more than a couple of seconds with
1:17
gaming being a common culprit so your processor starts out cool and fast then
1:24
the hotter it gets the more it thermal throttles so
1:28
liquid metal likely wouldn't do anything for that initial cold performance but
1:34
it could allow us to maintain peak performance for longer so we chose the
1:41
razer phone as our vic excuse me a test subject
1:44
compared to most phones its thermal design is very respectable but it is
1:49
still not perfect check this out our
1:53
first 3dmark result puts us in the top 83
1:57
of razer phones so that looks pretty good but then a second run immediately
2:02
afterwards gave much worse results and
2:05
it dropped all the way down to 20 worse
2:08
after a 15 minute stress test that is the kind of performance impact that you
2:13
would notice in an extended mobile gaming session
2:17
so let's get started then you'll need a good set of screwdrivers and prying
2:21
tools some isopropyl alcohol some paper towel some conformal coating cotton
2:26
swabs and a heat gun because getting inside phones sucks and of course you'll
2:32
also need liquid metal we'll be using thermal grizzly conduct-a-knot now your
2:37
phone's disassembly process will be different unless you have a razer phone
2:42
but we'd recommend watching this whole process anyway without skipping around
2:47
if you plan to follow along so first we made sure the device was off
2:52
then we took a heat gun to the speaker grilles with the adhesive softened we
2:56
peeled them off with a prying tool next we removed this combination of regular
3:00
phillips and torx screws we recommend always placing things like this in a
3:05
parts tray in the same positions they came out of the phone in so you don't
3:08
have to guess which ones go where during reassembly
3:12
then we used guitar picks to keep the phone from snapping back together while
3:15
we pried it apart until well it pried apart and the screen popped off then
3:21
once we got inside and took off the cables for the lcd screen and battery
3:26
giving us our first good look at the razer phone's heat pipe cooler it's
3:30
insulated from the battery and actually seems to be designed to use the screen
3:35
to increase its surface area for heat dissipation pretty cool with the stock
3:39
thermal paste removed it wasn't entirely clear actually how to proceed we lifted
3:46
this small copper heat spreader very carefully with a razor blade not to be
3:50
confused with a razor blade and then had a planning session so if liquid metal
3:56
gets on anything aluminum the gallium in it will destroy it with corrosion so
4:01
what we've decided is to put the best thermal compound that we have between
4:06
the copper sheet and the processor and
4:09
then liquid metal the heat pipe to the copper
4:13
heat spreader with regular thermal compound all around it time then to
4:18
execute we applied conformal coating around the CPU with a cotton swab to act
4:23
as a line of defense if the liquid metal spills off the CPU then to put our
4:28
copper heat spreader back on we used arctic silver thermal adhesive which you
4:32
mix up in equal parts and then spread across the surfaces that you want to
4:36
stick together just like an epoxy we then cleaned the copper spreader and
4:41
carefully placed it back on removing any wrinkles with a guitar pick and clamping
4:45
it all together for about 20 minutes to make sure that it was set
4:50
moving over to the back of the screen we applied a generous amount of thermal
4:54
paste here and then it was finally time
4:57
for liquid metal we put a small drop in a cleaned parts
5:02
tray then picked up a tiny bit with a cotton swab
5:06
this was carefully spread out over the copper heat pipe you only need a little
5:10
bit of this stuff to do the trick time for reassembly if you are performing
5:15
this mod on a razer phone by the way i would strongly recommend that you get
5:19
new speaker grilles first because they don't just stick back on so we used what
5:24
we fondly refer to as that sticky tar crap to put them back on as best we
5:28
could um i i give it a 4 out of 10.
5:32
anyway hitting the power button it boots
5:36
so now it's time for the payoff or lack thereof we weren't sure given that we
5:41
weren't liquid meddled all the way to the chip itself
5:44
if this was even really gonna work so in 3dmark we immediately recorded our
5:50
highest result yet but
5:53
not by a very significant margin cautious optimism at best at this point
5:58
then on the second run whoa
6:03
no decrease in performance whatsoever
6:07
also in the vulcan test which comes after the opengl one has finished
6:11
running we went from very middle of the road performance compared to other razer
6:16
phones to being in the top four percent
6:19
and our other benchmarks saw modest gains in performance too so this phone
6:24
right here it's got ugly grilles but you could game on it indefinitely and see
6:29
virtually no drop in performance an a
6:32
plus result so then would we recommend performing this
6:37
operation the answer is no
6:41
given the low mounting pressure for the cooler and the way that phones get moved
6:45
and tossed around all the time we believe that the chances of the liquid
6:49
metal shifting and damaging the aluminum inside your phone or even shorting
6:54
something out and bricking it entirely are too high
6:58
also we can't know how much of the performance increase came from the
7:02
liquid metal and how much was simply from re-pasting the phone with a higher
7:06
quality thermal interface material so bottom line then unless you're going
7:11
for phone performance records it's really cool and the results surprised
7:16
even us but i wouldn't recommend voiding your warranty over it
7:21
speaking of things i would recommend ting is the mobile carrier that's
7:26
focused on customer service and customer satisfaction when you call ting you
7:30
don't speak to a robot you get put through directly to a person and you
7:34
don't pay extra for the privilege the average ting bill is just 23 bucks a
7:38
month per device and if you're stuck in a contract and switch to tang they'll
7:42
cover 25 of your cancellation fee up to 75 bucks the cool thing about ting is
7:48
that you only pay for exactly the air time and data that you use and data is
7:53
now just 10 bucks a gig beyond the first gig so try out their savings calculator
7:58
it's over at Linus.ting.com we'll have that linked below and find out if you
8:02
would save money on ting when you sign up at our link you'll get 25 bucks in
8:06
service credit or towards a new device
8:10
so thanks for watching guys if this video sucked you know what to do but if
8:13
it was awesome get subscribed hit that like button or check out the link to
8:17
where to buy the stuff we featured in the video description also link down
8:20
there is our merch store which has cool shirts like this one and our community
8:24
forum which you should totally join no one no one needs to know if this was
8:29
a Linus who would have made it in the video but unfortunately my incompetence
8:34
generally goes under the radar do you actually think the editors are going to
8:37
take the time to go through all this footage and listen to it i really
8:40
strongly doubt it
