1
00:00:00,160 --> 00:00:07,120
i wasn't expecting a major innovation in case design this year and i certainly

2
00:00:04,400 --> 00:00:13,120
wasn't expecting it from hp but here it is the omen 45l possibly the

3
00:00:10,960 --> 00:00:18,240
biggest game changer in case cooling since the antec p180 introduced the

4
00:00:15,120 --> 00:00:20,800
concept of isolated cooling zones hp has

5
00:00:18,240 --> 00:00:25,039
dabbled in custom cases in the past but this

6
00:00:22,039 --> 00:00:28,160
scientifically cooled metaphysically

7
00:00:25,039 --> 00:00:30,480
fire design whatever that means is their

8
00:00:28,160 --> 00:00:36,480
first that there's just no other way to put it looks absolutely freaking amazing

9
00:00:34,640 --> 00:00:41,200
they even got a patent for what they call their cryo chamber cooling a

10
00:00:38,800 --> 00:00:45,600
solution that at least on paper makes the omen 45l one of the best cooled

11
00:00:43,520 --> 00:00:50,000
pre-builts on the market so

12
00:00:47,680 --> 00:00:54,320
what happened here our sponsor knows but they won't let me

13
00:00:52,320 --> 00:00:58,719

17
00:01:08,479 --> 00:01:11,479
Linus

18
00:01:15,040 --> 00:01:18,040
so

19
00:01:26,000 --> 00:01:33,840
the omen 45l boasts a top of the line spec sheet but none of that is what

20
00:01:30,720 --> 00:01:36,320
makes it unique what's special

21
00:01:33,840 --> 00:01:41,280
is all in the attic up here the top contains a liquid cooling radiator and

22
00:01:38,560 --> 00:01:47,040
120 millimeter cooling fans then there's this void with an angled airflow

23
00:01:44,159 --> 00:01:50,560
deflector that makes it a completely independent cooling zone so cold air

24
00:01:49,520 --> 00:01:54,960
goes in hot air comes out

25
00:01:53,200 --> 00:01:58,719
compromise cooling because the thing is in a traditional

26
00:01:56,880 --> 00:02:03,360
case layout you end up sacrificing cooling performance in some way no

27
00:02:01,040 --> 00:02:06,960
matter how you slice it either you mount the radiator in the front where it's

28
00:02:05,439 --> 00:02:12,879
going to pre-heat the air that ultimately gets sucked into your GPU or

29
00:02:10,399 --> 00:02:17,680
you mount the radiator in the top giving fresh air to your GPU which spits it out

30
00:02:15,360 --> 00:02:22,560
into your CPU cooler the bad news is that hp's patent means

31
00:02:20,319 --> 00:02:26,000
that nobody else can do this but the good news is that at least you can buy

32
00:02:24,239 --> 00:02:31,120
the case separately if you like what you see so why don't we take a closer look

33
00:02:28,080 --> 00:02:33,200
there's definitely some oem pc flare you

34
00:02:31,120 --> 00:02:37,680
got a nice tempered glass side panel but then you've got these little

35
00:02:35,200 --> 00:02:43,200
weird unpainted bits here i mean it's not a huge deal one really nice thing is

36
00:02:40,000 --> 00:02:46,160
check this out cable management grommets

37
00:02:43,200 --> 00:02:49,200
totally standard atx mounting this pass-through for the radiator tubes

38
00:02:48,239 --> 00:02:53,760
that's kind of a little weird but there's plenty of room in there you could

39
00:02:52,400 --> 00:02:58,000
definitely put thicker ones in if you really wanted to hold on a second

40
00:02:55,760 --> 00:03:01,040
there's a release oh look at this this is cool

41
00:02:58,959 --> 00:03:05,440
quick release front panel just got these little uh buttons right

42
00:03:03,440 --> 00:03:08,159
here easy to clean front filter is that

43
00:03:07,120 --> 00:03:11,360
magnetic i think it's magnetic

44
00:03:10,159 --> 00:03:16,800
yep all the RGB intake fans more oem pc

45
00:03:14,640 --> 00:03:20,959
weirdness this bottom fan is screwed in from the front because the basement kind

46
00:03:18,879 --> 00:03:26,640
of limits access to it and then the top fans are screwed in from the inside

47
00:03:24,319 --> 00:03:30,400
solid front i o on the case though if you buy the pre-built i'm not sure that

48
00:03:28,159 --> 00:03:34,159
it entirely makes up for the kind of flaccid rear i o on this particular

49
00:03:32,239 --> 00:03:38,159
motherboard and in a shocker from hp

50
00:03:36,480 --> 00:03:43,440
the cooling for the motherboard and actually look at that even the SSD for

51
00:03:40,319 --> 00:03:46,000
that matters pretty freaking awesome

52
00:03:43,440 --> 00:03:50,400
easy remove top panel that's a missed opportunity

53
00:03:47,760 --> 00:03:54,640
dual 240mm rad instead of a 360. i'm gonna see if that hurts us later

54
00:03:52,159 --> 00:03:58,319
curiously even though pc gamer reports that you can buy the case stand alone

55
00:03:56,560 --> 00:04:03,200
maybe it's coming later because i don't see it on the 45l page or under omen

56
00:04:00,879 --> 00:04:08,159
accessories on the us site coming back then to the pre-built which you actually

57
00:04:05,840 --> 00:04:12,400
can buy then hp claims that they've beefed up their motherboard vrm cooling

58
00:04:10,159 --> 00:04:17,359
and are using more off-the-shelf style parts this time around which it seems

59
00:04:14,720 --> 00:04:21,359
that they are and that's great in theory we already saw that they're at least

60
00:04:18,720 --> 00:04:26,320
using standard form factor motherboard case and power supply which should make

61
00:04:23,440 --> 00:04:29,520
future upgrades relatively painless but i just can't shake that feeling that

62
00:04:28,240 --> 00:04:34,800
something's rotten in the state of denmark here because here's the thing hp

63
00:04:32,080 --> 00:04:39,120
has a long history of kneecapping high-end components to the point where

64
00:04:36,880 --> 00:04:44,320
it almost feels like they intentionally limit their products performance

65
00:04:41,360 --> 00:04:48,720
so we need to deal with that but first we want to know if the cryo chamber is

66
00:04:46,479 --> 00:04:52,479
actually working as intended so we rigged up our omen 45l with four thermal

67
00:04:51,520 --> 00:04:57,600
probes one at the intake one at the exhaust for

68
00:04:55,680 --> 00:05:02,720
each of the two thermal chambers so the bottom and the top here and a final one

69
00:05:01,120 --> 00:05:06,800
measuring the ambient temperature in our room we then loaded up the system in

70
00:05:05,199 --> 00:05:12,400
three different ways first we hit all 16 of our CPU cores

71
00:05:09,520 --> 00:05:15,919
with prime95 small fft allowed our coolant temperatures to equalize in our

72
00:05:14,240 --> 00:05:19,919
radiator and found that there was a whopping 12 degree difference between

73
00:05:18,479 --> 00:05:25,120
the temperature of the air at our workbench and the radiator exhaust so in

74
00:05:22,960 --> 00:05:30,240
real world terms that means that if you were pulling hot radiator air into your

75
00:05:27,680 --> 00:05:36,000
gaming rig it could easily drive up your GPU temps by 10 degrees or more

76
00:05:34,000 --> 00:05:40,720
but what if we went the other way around feeding fresh air to the GPU first and

77
00:05:38,720 --> 00:05:44,000
then hoping that it can still cool our CPU afterward

78
00:05:42,560 --> 00:05:49,919
yikes running furmark we measured a 20 degree

79
00:05:47,039 --> 00:05:55,120
difference between our front air intake and our rear exhaust now this is a bit

80
00:05:52,880 --> 00:05:59,680
of a worst case scenario for that since most cases would feed at least

81
00:05:57,360 --> 00:06:04,880
some non-preheated air you know maybe from the top here into the radiator and

82
00:06:02,880 --> 00:06:09,280
there's only a single 120 millimeter exhaust but both of these scenarios

83
00:06:07,039 --> 00:06:13,280
demonstrate how you could easily end up cooling one of your components optimally

84
00:06:11,520 --> 00:06:18,479
at the cost of thermal throttling the other as for the crowd chamber does it work

85
00:06:17,520 --> 00:06:24,400
yes our final test a combined CPU and GPU

86
00:06:22,240 --> 00:06:28,960
load showed us that while the corner of my office where we were running the

87
00:06:25,840 --> 00:06:31,759
tests did heat up by a couple of degrees

88
00:06:28,960 --> 00:06:36,960
the way that hp routes the CPU heated air off to the side and then the GPU

89
00:06:34,720 --> 00:06:42,000
heated air out the back means that the entire system is getting

90
00:06:39,440 --> 00:06:46,479
ample access to fresh air it's freaking fantastic

91
00:06:44,080 --> 00:06:52,000
go buy one now not so fast our performance woes with hp

92
00:06:49,600 --> 00:06:57,280
desktops have never actually been caused by poor thermals

93
00:06:53,840 --> 00:06:58,880
so we need to know is it fast or is it

94
00:06:57,280 --> 00:07:03,840
just fast for an hp to find out we gathered up a

95
00:07:01,599 --> 00:07:08,240
test bench with the same specs using off-the-shelf gaming parts nuked hp's

96
00:07:06,639 --> 00:07:13,360
pre-installed software bloat because that's the first thing you should do when you buy an hp anyway and took our

97
00:07:11,360 --> 00:07:16,400
rigs to the drag strip and

98
00:07:14,479 --> 00:07:21,919
well this is a good omen get it out of the gate the 45l measurably

99
00:07:20,000 --> 00:07:27,919
outperformed our control bench in both f1 2021 and flight simulator 2020.

100
00:07:25,759 --> 00:07:31,840
cs go is a little less clear-cut with our control bench managing better

101
00:07:29,360 --> 00:07:36,160
averages but given that the omen posted better 99 minimum frame times i'm

102
00:07:34,160 --> 00:07:41,039
inclined to call this one a draw unfortunately the same can't be said of

103
00:07:38,720 --> 00:07:46,240
cinebench r23 what the heck is going on here

104
00:07:43,759 --> 00:07:49,919
how is it that you can come out ahead in gaming

105
00:07:47,199 --> 00:07:54,720
and then with exactly the same specs fall behind by nearly five percent in

106
00:07:52,639 --> 00:07:59,280
rendering like this

107
00:07:56,879 --> 00:08:05,039
it looks like whatever fuss hp has made about their beefed up vrms and keeping

108
00:08:02,160 --> 00:08:11,680
mother cool whatever that means the omen 45l's poor 12900k is so power limited

109
00:08:09,440 --> 00:08:17,360
under sustained load that even manually overclocking the course to 5.2 gigahertz

110
00:08:14,479 --> 00:08:21,759
results in basically exactly the same score

111
00:08:18,400 --> 00:08:25,360
it's a solid 32 watts below Intel's

112
00:08:21,759 --> 00:08:27,599
rated turbo power for this chip

113
00:08:25,360 --> 00:08:32,800
well that's a simple fix you might think fire up the UEFI BIOS set all of Intel's

114
00:08:30,400 --> 00:08:35,599
various boosts to their maximum and call it a day right

115
00:08:34,640 --> 00:08:39,360
wrong i have seen thin and light notebooks

116
00:08:37,760 --> 00:08:43,039
that have more available tuning parameters than this thing

117
00:08:41,760 --> 00:08:46,720
but i'm a gamer not a professional 3d

118
00:08:44,800 --> 00:08:50,160
modeler you might think who cares as long as it's gaming

119
00:08:48,320 --> 00:08:54,640
performance is good you do and here's why

120
00:08:52,320 --> 00:08:59,120
as i was puzzling about the performance advantage over our reference system i

121
00:08:56,399 --> 00:09:04,800
came across something odd hp went out of their way to equip this machine with xmp

122
00:09:01,920 --> 00:09:09,920
capable hyperx 3733 mega transfer per second at cl21 memory

123
00:09:07,120 --> 00:09:16,399
but they are running it at both lower speeds and higher latencies than it is

124
00:09:13,200 --> 00:09:18,640
rated at with absolutely no way to

125
00:09:16,399 --> 00:09:25,519
activate the xmp profile and run it at its full potential what the sam's honest

126
00:09:22,000 --> 00:09:28,080
hill is going on here hp

127
00:09:25,519 --> 00:09:32,800
now we've got another question to answer is our control system getting beat fair

128
00:09:30,399 --> 00:09:38,320
and square or is it only getting beat because we're forcing it to play in the

129
00:09:34,560 --> 00:09:39,839
same weak sandbox as the omen 45l

130
00:09:38,320 --> 00:09:45,120
what if we did what any sensible enthusiast who just spent over a

131
00:09:42,000 --> 00:09:48,399
thousand dollars on a GPU would do and

132
00:09:45,120 --> 00:09:52,160
spend another 20 bucks on our RAM

133
00:09:48,399 --> 00:09:54,320
holy bananas it's a bloodbath folks

134
00:09:52,160 --> 00:09:59,360
curiously our cinebench scores did go down a little bit but in gaming we have

135
00:09:56,640 --> 00:10:04,399
unlocked so much more performance that our control is beating the omen 45l by

136
00:10:02,240 --> 00:10:09,519
anywhere from a couple of percent to nearly 15 percent in flight sim 2020

137
00:10:08,800 --> 00:10:14,800
so yeah while our initial numbers have hp

138
00:10:12,480 --> 00:10:19,600
as the big winner it turns out that's only because they stacked the deck in

139
00:10:16,640 --> 00:10:25,120
their favor the silver lining though is that all of this is fixable either by hp

140
00:10:23,760 --> 00:10:29,440
seeing the light and fixing their power delivery

141
00:10:26,800 --> 00:10:34,079
limitations please hp i'm rooting for you here because otherwise i really like

142
00:10:31,040 --> 00:10:36,000
this thing or by just obtaining the case

143
00:10:34,079 --> 00:10:39,760
somehow and building your own while you're at it i've got a couple of

144
00:10:37,440 --> 00:10:44,640
suggested tweaks spend the extra 10 bucks and get a triple rather than a

145
00:10:41,839 --> 00:10:49,920
dual 120 millimeter radiator for the top upgrade that 850 watt power supply to a

146
00:10:47,279 --> 00:10:54,640
thousand watt just to be sure and maybe go for a full-size atx motherboard oh

147
00:10:52,560 --> 00:10:59,680
and leave out the mcafee and dropbox installs while you're at it you will end

148
00:10:56,560 --> 00:11:00,480
up with the same great omen 45l design

149
00:10:59,680 --> 00:11:06,160
just with less hpness choding it up

150
00:11:03,600 --> 00:11:09,760

and watch our second secret shopper series where hp pulled this exact same

162
00:11:50,240 --> 00:11:56,399
move and ended up with lower performance than

163
00:11:53,360 --> 00:11:58,399
the competition as a result oh i guess
