00:00:02

several times I did forced

00:00:03

cooling of the processor power circuits on the

00:00:05

motherboard and while doing this I

00:00:07

used a rhea tower cooler, every

00:00:09

time there were many people who

00:00:11

said that if there had not been a tower

00:00:14

cooler blowing on the board, then there would have

00:00:16

been no problems naturally. It definitely wouldn’t have helped

00:00:19

on the board where after a minute and a half I

00:00:21

turned off the load when it reached 200

00:00:23

degrees to prevent the

00:00:25

mosfets from soldering themselves,

00:00:26

simply blowing in a not very directed

00:00:29

way without a radiator will not remove 100

00:00:31

degrees, so commentators

00:00:33

still need to be more careful in their statements,

00:00:36

okay, I understand that the adviser I’m wrong,

00:00:38

but with such advice, people could

00:00:41

burn their computer because a person could

00:00:43

believe in all this, and naturally, when choosing a

00:00:46

motherboard for yourself, it is very important

00:00:47

to familiarize yourself in more detail with the capabilities and

00:00:50

power subsystem, as well as reviews of

00:00:52

board owners and reviews of these boards and

00:00:55

long more popular ones models, you

00:00:57

can find reviews and reviews on the website and

00:00:59

catalog

00:01:00

and also find out the main technical

00:01:02

characteristics of the boards, compare several

00:01:05

different boards and after the choice is

00:01:08

made without leaving the catalog, you

00:01:10

can also compare prices in stores in your

00:01:12

region and select the best

00:01:14

deals and then you can avoid

00:01:16

problems like this and you won’t have to

00:01:19

farm radiators to make air ducts.

00:01:21

With regards to the fact that there were tips to just

00:01:24

use a box cooler, naturally

00:01:26

blowing the motherboard removes some of

00:01:28

the heat,

00:01:29

that is, the box cooler, by blowing the radiators on the

00:01:31

board itself, will help reduce the

00:01:33

temperature of the vrm zone of the motherboard,

00:01:36

all that remains is to understand the degree of this

00:01:38

influence, especially the degree of this influence in

00:01:41

modern boards, I’m not just talking

00:01:43

about modern boards, and to

00:01:45

understand why you need to plunge a little into

00:01:47

history, the fact is that in old boards these are the

00:01:49

elements used and they are

00:01:52

soldered through a large-area contact

00:01:55

that gives excellent output heat is applied to the

00:01:57

metallization layer of the motherboard and this is

00:01:59

generally normal practice for power

00:02:01

elements of electronics, with magnification, the

00:02:04

metal

00:02:06

parts of the case are already seated without soldering, but the screws are pressed

00:02:09

against the radiator through a thermal pad.

00:02:11

This can be seen in any power

00:02:13

items, such as power supplies, and earlier,

00:02:16

say 10 years ago exactly This method of

00:02:18

heat input was paramount in

00:02:21

motherboards,

00:02:22

and just at that time they

00:02:24

usually used coolers whose fans

00:02:25

blew on the board itself, but

00:02:27

now mosfets assemblies of mosfets with

00:02:29

drivers transfer much

00:02:31

less heat to the payment and it is assumed that either

00:02:34

they will not be heavily loaded close to the

00:02:36

maximum accordingly, the current

00:02:38

will not heat up much, or they will

00:02:40

transfer heat to separate radiators;

00:02:42

this allows you to increase the

00:02:45

airflow capabilities since there is already a radiator and,

00:02:47

in addition, reduces the heat flow to the

00:02:49

motherboard so as not to heat up

00:02:51

neighboring elements, because for mosfets

00:02:53

heating less than 100-120 degrees is not critical, and

00:02:56

this for them I have a normal temperature, but

00:02:59

the capacitors that are standing next to each other are not

00:03:01

very happy about this; they are adjacent often

00:03:03

tend to leave their case precisely

00:03:05

for the hot mosfets

00:03:07

and I am making this video because

00:03:10

some general traditions for assembling a computer,

00:03:12

its cooling almost never changes

00:03:14

and since the design and the

00:03:16

vrm element have changed,

00:03:18

then it’s worth checking, in principle, the degree of

00:03:20

influence in the house of paying for the side cooler, is there

00:03:22

any significant

00:03:24

effect left from blu efficiency, all that remains is to

00:03:28

carry out the appropriate tests,

00:03:30

I measured everything and the pyrometer, I initially

00:03:32

decided that it would not be so clear

00:03:35

since synchronize pyrometer measurement runs

00:03:36

and this is not the same as

00:03:38

synchronizing game benchmarks, although

00:03:40

looking ahead I will say that

00:03:42

I was able to synchronize pyrometer runs about payment,

00:03:44

however, I decided

00:03:46

that it was necessary to pay with a

00:03:48

working and adequately indicating

00:03:50

temperature sensor from January and

00:03:53

I only have one of these this board is for socket am4,

00:03:56

fortunately I have both a box cooler and a

00:03:58

tower cooler for am4,

00:04:00

but still there is one problem, namely

00:04:03

that I bought the boards last year

00:04:05

based on this year and soon this board will

00:04:08

take over 12 cores, but now the

00:04:11

longest-lasting processor on my M4 is a

00:04:13

Ryzen

00:04:14

400, and the boxed cooler for it is the

00:04:17

thinnest pancake from the line of boxed

00:04:19

coolers on the M4. The essence of the problem is that

00:04:22

if you don’t overclock the processor, the product

00:04:23

heats up within plus ten degrees of

00:04:25

room temperature and under such

00:04:28

conditions the difference is that widows can’t see the

00:04:30

heating a little higher in overclocking, but the boxed

00:04:32

cooler does not overclock with overclocking damn it

00:04:34

while in the summer heat, so

00:04:37

I made 2 in 1 sets of tests,

00:04:39

I drove the processor with overclocking to 39 x

00:04:42

hertz

00:04:43

but with a boxed cooler at reaching 93

00:04:46

degrees, I turned off the Lin Pact for 5-10

00:04:48

seconds and at about 6 minutes I took

00:04:51

temperature measurements with the tower cooler. I

00:04:54

didn’t turn off anything and took measurements

00:04:56

for about 5 and a half minutes,

00:04:58

but I still did

00:05:00

n’t get any sensible results. as the processor

00:05:02

itself apparently began to warm up the

00:05:04

board around itself, it still kept

00:05:07

it above 90 degrees; in addition,

00:05:09

the box cooler did not blow the radiator with a direct flow of air,

00:05:12

while the

00:05:15

tower cooler hit

00:05:17

one of the two radiators with a direct flow of air,

00:05:19

namely the short one so the small radiator

00:05:22

was blown by the tower cooler, its

00:05:24

temperature even 20 minutes after the

00:05:26

start of the test

00:05:27

was lower than the temperatures with the box

00:05:29

cooler after a couple of minutes linpack

00:05:31

in general, practice has shown that in fact it does not

00:05:33

happen that the cooler does not

00:05:35

blow on the radiators at all

00:05:36

since the radiator is high, which is already

00:05:39

placed under doubt the very purpose of determining the

00:05:41

degree of influence of the box blowing the cooler

00:05:43

simply because the tower cooler blowing the

00:05:46

radiator is stronger than the box cooler

00:05:48

and in addition the processor itself introduces

00:05:50

errors because the processor was in

00:05:52

one of the cases much hotter than the

00:05:54

mosfets

00:05:55

so we had to slightly

00:05:56

adjust the reality by bringing

00:05:58

conditions such

00:05:59

as to get a more controlled one an

00:06:01

experiment with cleaner results,

00:06:03

for this I removed the radiator from the mosfets,

00:06:06

thereby giving them the opportunity to heat up

00:06:09

higher, approaching the processor temperature, which

00:06:12

significantly reduces errors from

00:06:14

different temperatures of processors on different

00:06:16

coolers, and I also eliminated the

00:06:18

ability of the tower cooler to blow on the

00:06:20

mosfets by blowing on the radiators. Did

00:06:23

they work successfully? for the demonstration of a boxed cooler,

00:06:25

I reduced the frequency to 3 7 gigahertz and the

00:06:28

voltage to 125 volts,

00:06:30

in fact, in this form it is already possible to

00:06:32

carry out testing,

00:06:34

20-minute runs, learn these gave the

00:06:36

desired results, by the way, if

00:06:38

anyone knows how to save the log in a new

00:06:40

network, then write about it in

00:06:42

comments this design is beautiful but

00:06:44

without lags there is no use in this software 0 as

00:06:47

earlier it does not dump results and graphs into documents

00:06:49

here you can see the

00:06:51

flow to the temperature of the mosfets that the

00:06:53

boxed cooler gains as much as eight

00:06:56

degrees, this is quite a lot considering that the

00:06:58

room was about twenty-eight

00:07:00

degrees then there is a box with a cooler

00:07:02

heating + 31 degrees with a tower plus 39

00:07:05

degrees and according to the data from the pyrometer, the

00:07:08

power line under a small radiator with a box cooler has

00:07:10

copper temperatures from 42 to 50

00:07:13

degrees and with a tower a color from 54 to

00:07:17

50 6 degrees, that is, the same six

00:07:19

ten degrees the

00:07:20

main power circuit of the cores with a box

00:07:23

color has a temperature of 60 to 71

00:07:26

and with a tower from 50 8 to 75 in general for

00:07:30

most mosfets

00:07:31

45 degrees more was from the towers with a

00:07:34

cooler actually these are the results

00:07:36

roughly speaking we got a difference of five

00:07:38

ten degrees when heated in mosfets at

00:07:40

about 30-40 degrees C above room

00:07:42

temperature, it is natural that when heated in

00:07:45

mosfets to higher temperatures, the difference

00:07:47

will be higher since the difference between the

00:07:49

temperature of the air and the body of the mass

00:07:51

will be greater. Unfortunately, it is impossible in

00:07:54

any way to extrapolate the

00:07:56

results obtained at one

00:07:58

temperature in any way - then certain

00:08:00

linear laws or some other more

00:08:03

complex conditions when, unlike in

00:08:05

my case, there would be enough in the area, that is, the

00:08:07

mosfets were heating up bds, then 120 degrees is

00:08:10

equal to co could be and is played in 15-20

00:08:13

or even more, which is quite significant and

00:08:16

definitely in In some cases, it makes

00:08:18

sense to give preference to buying a

00:08:21

boxed cooler, first of all, this

00:08:23

condition is the absence of good ventilation of

00:08:25

the case, the absence of radiators in the zone,

00:08:28

we believe in this case, hot air

00:08:32

accumulates somewhere in the upper part of the case, including in the r.m. and when

00:08:34

you haven’t been

00:08:35

haley for a long time the back panel of hot air, then the

00:08:38

box cooler will create at least

00:08:39

some air movement and make a

00:08:42

big difference on rafts that have

00:08:44

problems with accidents; however, I didn’t just

00:08:47

say that the first approach to

00:08:49

testing turned out to be unsuccessful

00:08:50

in reality in fact,

00:08:52

some unsuccessful tests often occur, you have to

00:08:54

do some before changing

00:08:55

the conditions and usually I don’t show these unsuccessful tests

00:08:58

in the same way, and then redo everything for him

00:09:00

according to the second type of tests and do

00:09:02

n’t talk about the first ones, I told him about

00:09:05

him because in those conditions, the tower

00:09:08

cooler turned out to be more advantageous for temperatures for the

00:09:10

Jews; the tower cooler, with a direct flow

00:09:13

of air, touched one of the two radiators,

00:09:15

and also this radiator inside the

00:09:18

case could be part of the overall

00:09:19

blowing system of the case, that is, direct the

00:09:22

flow and, thanks to a larger fan and

00:09:24

direction in the right direction, it

00:09:26

could reduce the overall temperature air in

00:09:28

the case thanks to improved ventilation,

00:09:31

thereby reducing the temperature of all

00:09:33

components in the case, including the NVM and

00:09:36

also the video card, power supply, other

00:09:38

components, and also with a tower cooler, the

00:09:43

processor temperature came out much lower than about 30 degrees with

00:09:45

comparable noise levels, despite the fact that

00:09:47

this cooler is one of the cheapest additives

00:09:50

the processor, due to overheating with a side

00:09:52

cooler, heated the motherboard for a

00:09:53

new Rome, including the

00:09:55

capacitor, and there are definitely a lot of

00:09:58

cases when using a tower

00:10:00

cooler will be even more advantageous for the

00:10:03

temperature of the vrm zone,

00:10:04

in general, everything is not as simple as

00:10:06

I would like I also left an unsuccessful experience for this

00:10:09

video precisely in order to

00:10:11

show that there is no clear best

00:10:13

solution, what was actually shown should

00:10:15

have been enough so that in general one could

00:10:18

imagine what situation would be

00:10:21

more profitable for a specific computer for a

00:10:23

specific motherboard and a

00:10:25

specific case with the fans selected for

00:10:27

this case and

00:10:29

air currents I hope the video was useful or

00:10:32

interesting if so then subscribe to the
