00:00:00.199 --> 00:00:07.600
welcome back to the workshop today we're going to be checking out power supply positioning we've heard a bunch of stuff

00:00:04.759 --> 00:00:10.840
over the years uh with case feet do this without case feet do that with a

00:00:08.960 --> 00:00:14.559
basement do this turn the fan so it's facing up into the case cuz it can help

00:00:12.400 --> 00:00:17.480
cool your graphics card and all this other mumbo jumbo so let's try it out

00:00:16.560 --> 00:00:22.720
we're going to do a bunch of different scenarios we have a case that has a basement in it and we're going to have

00:00:20.519 --> 00:00:27.240
the fan going up and down clear winner here is probably obvious but anyways uh

00:00:25.480 --> 00:00:30.720
without a basement we will do the power supply fan up and down and with a

00:00:29.560 --> 00:00:35.120
reference uh rear exhaust cool graphics card and

00:00:33.000 --> 00:00:37.800
with an internal exhaust graphics card we're also going to take system

00:00:36.200 --> 00:00:41.960
temperatures and GPU temperatures and power spy temperatures and ambient

00:00:39.280 --> 00:00:48.429
temperatures and thermometers everywhere let's get

00:00:50.840 --> 00:00:57.920
started gfuel is the sugar-free Alternative Energy beverage to maintain

00:00:55.520 --> 00:01:02.960
focus and endurance in long days and gaming sessions save some money with our

00:01:00.320 --> 00:01:07.080
offer code at the link below so our first test has the power supply in the

00:01:04.720 --> 00:01:11.200
bottom facing down so the fan is pulling up from under the case and exhausting

00:01:08.960 --> 00:01:17.000
out the back this should not contribute to the system's temperature at all but I

00:01:13.840 --> 00:01:19.159
want it for uh like initial test anyways

00:01:17.000 --> 00:01:23.520
for the rest of the system I have a 390x not overclocked but running The Crisis 3

00:01:21.439 --> 00:01:28.880
Skybox test which will be putting stress on it and the CPU which is running on

00:01:26.119 --> 00:01:34.960
top of a hyper 212 Evo the CPU here is a 4790 K which is overclocked at 1.35 Vols

00:01:33.479 --> 00:01:38.840
so it should be generating some heat as well and with an air cooler instead of a

00:01:37.159 --> 00:01:43.240
water cooler it should actually be dumping heat into the rest of the system

00:01:40.799 --> 00:01:46.759
too so this is a pretty hot air environment so now that we're good to go

00:01:45.399 --> 00:01:51.200
we're going to wait 10 minutes so everything can heat up okay so the first

00:01:49.040 --> 00:01:55.920
test is done our ambient outside the case right now looks like it's about

00:01:53.280 --> 00:02:00.320
25.4 I'm going to take this off of the front which is our thermal probe and

00:01:58.399 --> 00:02:05.079
then hopefully I can read an ambient temperature inside of the case looks

00:02:03.119 --> 00:02:10.000
like it's about 412 so that's actually quite hot inside

00:02:07.840 --> 00:02:16.760
of the case so just checking the numbers now it looks like the power supply is

00:02:11.720 --> 00:02:19.879
running at 32.5 de C at an RPM of about

00:02:16.760 --> 00:02:23.720
530 give or take a little bit the

00:02:19.879 --> 00:02:28.400
graphics card was running at about 87° C

00:02:23.720 --> 00:02:30.400
and the CPU was running at about 74° 72°

00:02:28.400 --> 00:02:34.000
C now we're we're going to try it with the power supply fan pointing up into

00:02:32.400 --> 00:02:38.200
the case but remember there is that basement panel there so I don't really

00:02:35.800 --> 00:02:42.000
expect this is going to go too well but we'll check out the numbers in 10

00:02:39.560 --> 00:02:46.760
minutes okay so the second test is done the outside temperature is at 25.5 de

00:02:45.239 --> 00:02:49.760
okay and then the temperature inside the case is looking like again it's right at

00:02:48.680 --> 00:02:53.440
about 41.5 we're getting the same temperature

00:02:52.040 --> 00:02:57.000
which is pretty much what I expected because the Thermal Zone in the bottom

00:02:55.159 --> 00:03:00.319
where the power supply is is isolated so turning it around shouldn't actually

00:02:58.560 --> 00:03:03.760
change anything we're just making sure that it doesn't Okay so checking out the

00:03:02.440 --> 00:03:07.799
power supply first it looks like it's about 40° C and we're running in fan RPM

00:03:07.000 --> 00:03:13.760
of 640 which is considerably higher than

00:03:10.120 --> 00:03:15.360
the 530 from before our GPU temperature

00:03:13.760 --> 00:03:20.360
during the test was sitting at right about 89° consistently throughout the

00:03:18.040 --> 00:03:25.840
entire thing and then the CPU was running at about

00:03:22.599 --> 00:03:28.159
67° so really the GPU and CPU had no

00:03:25.840 --> 00:03:32.599
change overall so we have now moved the system to the Define R5 I took the modu

00:03:30.799 --> 00:03:37.439
vents off the top so that it can breathe up there a little bit the fans are all

00:03:34.599 --> 00:03:41.640
plugged in and we are now taking the ambient temperature of the room from the

00:03:39.879 --> 00:03:45.400
side of the case because we like taking that right where the case is intaking

00:03:43.760 --> 00:03:48.799
air so we're taking it from the side because the front is a solid block the

00:03:47.760 --> 00:03:52.560
first test that we're going to be doing in here is the power supply pulling air

00:03:51.040 --> 00:03:58.159
in from the bottom and exhausting it out of the back with an internal exhaust GPU

00:03:55.519 --> 00:04:03.959
so a pretty standard setup the temperature going into the case in terms

00:03:59.560 --> 00:04:05.400
of of room Ambience is at about 25.7 de

00:04:03.959 --> 00:04:10.720
and then the temperature inside the system in terms of Ambience is about

00:04:07.920 --> 00:04:14.280
42° which is actually pretty damn hot now we move on to the software stuff we

00:04:12.879 --> 00:04:19.639
get to see that our power supply is running at about 584 RPM at a

00:04:16.919 --> 00:04:24.320
temperature of 35° C our CPU is running at about what looks

00:04:23.360 --> 00:04:29.759
like 67° which is on par with what it was

00:04:26.639 --> 00:04:31.880
doing before and our GPU temperature is

00:04:29.759 --> 00:04:36.080
actually pretty hot at 94° throughout the main testing

00:04:37.440 --> 00:04:44.400
area so now things get interesting we're in the same case same graphics card set

00:04:42.000 --> 00:04:49.199
up internal exhaust same tests all that kind of stuff but now the power supply

00:04:46.840 --> 00:04:54.000
has its fan pointed upwards some people say that this can help your GPU thermals

00:04:51.720 --> 00:04:56.759
or your system thermals as it pulls air out and then out the back of the power

00:04:55.560 --> 00:05:02.160
supply and the power Supply's temperatures will be fine anyway so

00:04:59.120 --> 00:05:04.400
we'll see if it actually does That Dun

00:05:02.160 --> 00:05:10.960
Dun Dun okay so for that test the room

00:05:07.080 --> 00:05:13.160
temperature was at about 25.8 de the

00:05:10.960 --> 00:05:19.840
system temperature we will grab right now yep that's 42° so basically no

00:05:17.199 --> 00:05:25.120
difference at all so the CPU is more or less at about 67° there is quite a bit

00:05:22.120 --> 00:05:28.600
of spikiness here also the GPU is still

00:05:25.120 --> 00:05:31.240
at 94° C now scrolling down to look at

00:05:28.600 --> 00:05:36.680
the core CLA to see any differences there it is also about the same it's at

00:05:34.000 --> 00:05:40.600
about 1040 in terms of core clock so it's not running at 94° but a little bit

00:05:38.639 --> 00:05:45.800
faster a little bit slower it's just it's doing the same thing but the power

00:05:42.960 --> 00:05:50.600
supply was a bit hotter so time to investigate more all right we have now

00:05:48.000 --> 00:05:57.680
removed our internal exhaust stricks 390x so I put in a 290 which should kind

00:05:54.880 --> 00:06:01.560
of you know take a little bit more power and probably cause a little bit more

00:05:59.639 --> 00:06:06.960
thermal destruction to the inside of the case so now 10 more minutes and we'll

00:06:04.520 --> 00:06:10.919
see how a rear exhaust card and a fan pointing upwards from the power supply

00:06:08.960 --> 00:06:13.199
manages to cool the whole system the temperature in the room right now is

00:06:12.080 --> 00:06:18.120
about 26° looks like our overall system

00:06:15.440 --> 00:06:24.960
temperature is way lower sitting at about

00:06:21.639 --> 00:06:28.599
29° the power supply is running at 36.5

00:06:24.960 --> 00:06:30.880
de with a fan RPM of 536 so the power

00:06:28.599 --> 00:06:37.960
supply is not even pushing that hard the GPU before I opened snag it was running

00:06:33.680 --> 00:06:43.080
at about 94° C with a clock speed of

00:06:37.960 --> 00:06:48.680
around mid 600s to Mid 700s and then our

00:06:43.080 --> 00:06:51.280
CPU is sitting at about 62°

00:06:48.680 --> 00:06:55.759
C okay so the last test is running right now the Skybox test is on the screen the

00:06:53.440 --> 00:07:00.199
rear exhaust card is installed and the fan on the graphics card is oriented

00:06:58.160 --> 00:07:06.599
pointing downwards so we'll see you in 10 minutes okay so the temperature in

00:07:02.520 --> 00:07:08.039
the room is a solid 25.8 de okay and

00:07:06.599 --> 00:07:16.800
then the temperature in the system is at about 29 28.9 29.1 de which is more or

00:07:13.440 --> 00:07:19.879
less what it was before so the internal

00:07:16.800 --> 00:07:21.879
temperature is the same power supply

00:07:19.879 --> 00:07:27.639
numbers here's a second okay so it's running at 41° cus but the fan isn't

00:07:25.000 --> 00:07:34.720
even spinning so it's not really trying that hard the graphics card is running a

00:07:31.000 --> 00:07:38.680
core clock of so it's 700 and something

00:07:34.720 --> 00:07:40.840
to 600 and something and the temperature

00:07:38.680 --> 00:07:48.240
is about 94° so there's no real difference there and the

00:07:43.199 --> 00:07:51.080
CPU is running at about yeah

00:07:48.240 --> 00:07:56.639
62 just before people ask for additional information the fan speed on both the

00:07:53.120 --> 00:07:58.159
graphis cards were both pinned at 45% so

00:07:56.639 --> 00:08:03.000
those should not have been changing and the fans throughout the syst system on

00:08:00.319 --> 00:08:06.639
both cases were pinned but I did use different fans again the system

00:08:04.879 --> 00:08:09.639
temperature and whatnot between the two shouldn't even really be compared their

00:08:08.120 --> 00:08:13.520
different cases using different fans whatever just isolate those tests so the

00:08:12.039 --> 00:08:17.479
information here is interesting and there's actually a few different results

00:08:15.039 --> 00:08:21.319
that you can come to depending on what scenario and what case type that you

00:08:19.560 --> 00:08:24.960
have so I'm hoping that these results are interesting to you some of them are

00:08:23.280 --> 00:08:28.960
fairly obvious like if you have a basement in your case don't point the

00:08:27.039 --> 00:08:33.839
fan towards the like roof of the basement where it can't breathe at

00:08:31.279 --> 00:08:37.760
all yeah the ones where it's like an internal exhaust graphics card it didn't

00:08:36.000 --> 00:08:42.039
really seem to help the graphics card which is what I was kind of help hoping

00:08:39.279 --> 00:08:46.040
for and it did increase the heat of the power supply one interesting thing that

00:08:44.120 --> 00:08:51.279
we did notice was with rear exhaust graphics cards if the power supply had

00:08:48.600 --> 00:08:55.040
its fan turned up into the case it actually did perform better in terms of

00:08:53.240 --> 00:08:58.560
the power supplies temperature nothing else not the system not the graphics

00:08:56.519 --> 00:09:01.640
card not the CPU nothing but the power supplies I'm assuming that's because

00:09:00.279 --> 00:09:06.040
there's air coming in through the front of the case that's fresh and nice and

00:09:03.560 --> 00:09:10.600
cold and is being pushed over top of the power supply and then out the back so

00:09:07.880 --> 00:09:15.920
it's able to breathe fresh nice cold air but what we did learn today is that it's

00:09:13.000 --> 00:09:20.720
not that big of a deal which is a very unfortunate and consistent conclusion of

00:09:18.200 --> 00:09:24.279
the workshop but there is different results per test and it's mainly based

00:09:22.959 --> 00:09:29.720
around the temperature of the power supply so while we're still definitely

00:09:26.800 --> 00:09:33.720
within uh what's safe for a power to run at you might be able to change your

00:09:32.000 --> 00:09:38.519
orientation or do something slightly different in order to fine-tune things

00:09:35.680 --> 00:09:43.240
because a zero overall impact in terms of your graphics cards performance and

00:09:40.519 --> 00:09:47.200
temperatures and whatever and saving a fairly noticeable amount of degrees on

00:09:44.760 --> 00:09:51.000
your power supply might not be a bad idea in terms of overall Longevity if

00:09:49.560 --> 00:09:54.079
you guys want to test it out and try it with your own graphics cards and your

00:09:52.560 --> 00:09:57.920
own systems with different setups and all that kind of stuff do it check it
