how bad could a $5 heat sink that we
0:05
bought on eBay possibly be how do you
0:08
even make a computer cooler for
0:12
$5 to our door
0:17
$5 well we're going to find out on the
0:20
cheapest heat sink on the market and yes my friends we are starting another
0:25
series the cheapest on the market and it's going to be flipping awesome
0:40
hp's new Omen X lineup comes equipped with Intel's 7eventh generation core i7
0:46
processor check it out at the link in the video
0:49
description the brand is XY CP and this
0:54
is the whatever that is CPU Cooler 65 W
0:58
maybe that says 3 warranty and it also has support for core i7 and 12 something
1:05
okay let's get it open
1:10
wow so that my
1:14
friends holy crap it's like feather
1:18
light that is $5 worth of heat sink I mean look at
1:23
this when they were designing the the flower heat sink fin Arrangement like
1:28
this just looks like a you know someone accidentally you know bumped it on the
1:32
uh assembly line see this hook kind of came off there see no problem no problem
1:37
you just put that baby back together no big deal but but look at this they uh
1:43
there were like wasn't room for the for
1:47
the frame for the fan so they're just like no problem well just bend it no big
1:52
deal no problem that's where the that's where the wire comes out okay so we're
1:57
looking at an 80 mm fan or somewhere in
2:00
between like 75 mm fan I think that's 80 mil oh man this stuff this stuff looks
2:08
quality let me see there m that's a good stuff that's a
2:14
good stuff right there W it's really runny actually that doesn't look
2:19
especially quality look at this look at this it's just like it's like a little
2:24
thermal volcano warning remove before
2:27
installation warning have your head checked before
2:31
installation all right so you can see what they've done here the construction
2:35
method is pretty actually very very basic so they've got these uh these
2:40
pieces right here that are basically running all the way through and
2:45
compressing so they've got all these fins coming in and you can actually
2:49
follow the lines cuz it's quite cheaply made this is a very old old construction
2:53
method they've got these four pieces of aluminum on either side that extend the
2:58
base and that are basically used to crush all the fins together then they
3:04
machine the bottom as flat as they can in a couple of minutes there and ship it
3:08
off now let's put this thing up against
3:12
its main competitor so the stock Intel heat sink with the fan and the mounting
3:16
hardware is 180 g this bad
3:20
boy comes in at
3:24
157 can it possibly hold up so first
3:28
things first we've got to clean off our CPU with alcohol for the most Fair
3:33
possible comparison we're using a 7700k then I've got a brand new Intel
3:39
stock cooler going to go ahead and throw that bad boy on there so I'm using the
3:45
included thermal compound we're not introducing extra variables in our test
3:50
so we're going to hit this baby with an i to 64 stress test here we
3:55
go utilization 100%
4:00
CPU temps well we'll give them a
4:06
minute I'm just taking in the uh the
4:10
sounds of the of the heat
4:22
sink okay so you can probably hear the way that the fan is
4:32
you hear that ramping up and ramping down so our temperatures and our turbo
4:38
speed actually reasonable so we're hanging in here at
4:43
4.45 GHz on our 7700k all the way up to 4.5 so this
4:48
thing's turboing up to the max at 100%
4:52
load and we're sitting at about 85° on the CPU package
4:58
ideal perhaps not but certainly not
5:01
going to damage it but what we also hear is that that fan is working really hard
5:07
to keep it there so let's lock that sound in our
5:12
minds and try out our $5 heat
5:16
sink all right so with it clean now we can put on
5:21
our uh thermal lava here oh look at that
5:27
that oh oh shoot oh
5:31
crap okay well oh quality oh beautiful okay okay
5:40
now I'm ready with my mounting hardware you basically put these little clear
5:43
plastic inserts into the hole that corresponds to the socket you want so
5:47
it's 775 or 1150 whatever then we just I
5:52
guess put this on here oh do not tell me this is not going
5:56
to align oh man oh you hear that
6:02
crunching um oh shoot I legitimately
6:05
don't know if it's going to fit that way oh how am I going to get this out
6:11
now okay maybe if I
6:14
can press it ow oh
6:21
crap shoot it's hooked on there real good
6:25
now well maybe I can get this side I don't know how I'm going to remove this
6:28
after
6:35
shoot ow okay I got to get the video card off
6:39
here okay well there are some Creature Comforts that definitely come with using
6:44
a uh a more modern design but if we put
6:47
it on this way I think we might actually be okay
6:51
here shoot it's going to interfere with the RAM before I can press it all the
6:55
way down K take the RAM out here we go
6:59
oh going to make it over that yes
7:02
okay we have a mount but can I get the
7:06
RAM back in now that is the
7:09
question oh I'm sorry gkill I'm sorry to
7:13
subject your memory to this ah there we go look at that it's like
7:19
it's designed for it it sits like right
7:22
there yeah yeah boy all right let's turn this
7:27
thing on all right right so it's got this like you know
7:32
orange spinning style you know what it
7:35
actually looks pretty cool I I
7:40
legitimately think it looks cooler than the stock heat sink just because of that
7:44
that Orange fan uh systems booted so we
7:47
clearly haven't outright broken
7:51
anything oh boy I don't think this is a
7:55
good sign I already heard it ramp up for a
7:58
second there but let's fire this up oh okay that's
8:03
all fine Miss okay here we
8:08
go oh oh
8:14
dang
8:17
101° on the CPU package H it's painful
8:23
look at the throttling look at the throttling
8:30
19% thermal throttling oh the
8:35
humanity oh we've already fallen from
8:38
4.5 to 4.24 GHz it just can't keep
8:46
up ah so if the question was could a $5
8:54
heat sink be worse than a free heat
8:58
sink the the answer is in fact yes my
9:02
friends but does its performance hold up to what
9:09
I would expect for a $5 product given
9:13
that if you try and buy one of these on eBay it'll actually cost you about
9:19
$15 then yes yes it holds up to what I
9:23
would expect I am shocked that we got anything for
9:27
$5 even something as ineffective as this
9:32
remember it's rated for 65 Watts not the 95 Watts we threw at it we were just
9:37
wondering if hey you know maybe it was
9:40
you know under promise overd deliver and
9:44
