Thermal margin что это

What is Thermal Margin? [Explained]

While designing the first-ever processor in 1971, one of the biggest challenges that engineers had to overcome was keeping the temperature at an optimal level. Even after 50 years of technological advancement, the key reason behind a processor’s performance drop is high temperature. The concept of thermal margin came so that we could monitor the temperature of the CPU.

What is Thermal Margin?

The thermal margin of a processor refers to the difference between the highest theoretical temperature at which a CPU can function without throttle and the actual temperature of the CPU under current load.

What Does Thermal Margin Mean?

It is very simple to define thermal margin. Every processor has a theoretical thermal limit. Meaning, the manufacturer runs various tests on the CPU and provides a temperature limit that the processor should not cross. The thermal margin basically means the difference between the theoretical thermal limit and the current temperature of your processor.

For example, let’s say at this very moment your processor’s thermal margin is 30. That basically means, if the theoretical thermal value (Max Thermal Limit) of your CPU is around 120 degrees, your processor is running at around 90 degrees Celsius.

You might be wondering what is a good thermal margin. In most cases, having a processor thermal margin of 43 degrees to 30 degrees is ideal for the longevity of the CPU.

CPU Thermal Margin

“What is CPU thermal margin?” is a commonly asked question especially among those who own an overclockable processor. I know many people choose high-end CPUs solely because of having awesome overclocking capabilities.

But before trying to make your processor run faster than it already does, having the basic knowledge of thermal margin is essential.

When it comes to CPUs, the theoretical thermal limit is set not just based on some absolute suitable condition. The processors are used in different conditions and after several cycles of testing, the theoretical thermal limit is set.

One of the biggest misconceptions regarding thermal margin is, your processor can run optimally at the theoretical temperature provided by the manufacturing company. But semiconductors are temperature sensitive and will malfunction in a very hot environment.

AMD Thermal Margin Explained

By reading AMD CPU’s thermal margin, you can understand how much room you have for overclocking with the current running hardware.

Owning a very good cooler should further increase the margin. Nowadays, AMD CPUs come completely unlocked and opens great opportunities for overclocking.

Now, AMD and Intel processor thermal margin is quite different since they are designed differently and have a different number of transistors.

If you are interested in overclocking, keep in mind that having a thermal margin of at least 30 degrees Celsius is essential for keeping your AMD CPU operational.

Difference Between Good and Bad Thermal Margin

A good thermal margin basically means having a marginal difference between the theoretical max temperature and the current temperature of the CPU is optimal.

A bad thermal margin indicates your CPU is excessively heating up due too much load or the processor fan is malfunctioning.

In general, having a thermal margin of 30 degrees or more under optimal load is ideal. If the margin goes beneath 10 degrees and slowly climbs towards zero than that is alarming.

How Does Thermal Margin Work?

As I have mentioned earlier, the thermal margin basically means the difference between the theoretical temperature and the current temperature of your CPU.

How Thermal Margin Relate To Temperatures

Engineers set a thermal margin on the basis of heat-exchange physics. Now, if you are running a computer right now, two major components are producing heat. They are the processor and a quiet nice graphics card.

Every time when a transistor goes to the “ON” state from the “OFF” state and vice versa, a certain amount of heat is produced. That heat cannot stay and rotate inside the processor as the flow of holes and electrons of the transistors will be interrupted. That is why manufacturers use a metal shield for sinking the heat out of the semiconductors.

Now, the more transistors a processor has, the more heat will produce. There is a very good chance that the processor you are currently using has more than a billion transistors. The engineers have worked hard to design a processor that contains 3.8 billion transistors!

One of the biggest issues of increasing the number of transistors of a CPU is, the exhaust heat is too much. That is why after doing many cycles of testing, they set a theoretical temperature value for the processor. Exceeding that value will destroy the CPU. This theoretical value determines what the thermal margin of a CPU Should be.

Thermal Margin vs CPU Temp

The current temperature of your CPU helps to determine the thermal margin, but they are not the same thing.

The current temperature of your CPU refers to how much heat the processor is producing while running your system.

On the other hand, the thermal margin is calculated by subtracting the current CPU temperature from the theoretical temperature that manufacturers have provided.

People use thermal margin mainly for overclocking purposes, but it is also an indicator of your CPU’s working condition.

Thermal Margin AMD Overdrive

One of the best ways to observe the thermal margin of your AMD CPU is using thermal margin AMD overdrive. This software will show the exact frequency of your processor, the multiplier value, VID of your processor, and thermal margin. The thermal margin is located in the fourth row.

This amazing software was developed by an independent developer and it is one of the best overclocking apps out there.

Now, you might be wondering, is AMD Overdrive safe? Many people around the globe use it frequently so you won’t have to worry.

Intel also has its own proprietary processor temperature monitoring software called real temp. And there is also 3 rd party software such as Coretemp that works on all CPUs whether it be Intel or AMD.

When it comes to AMD Overdrive Vs Realtemp vs Coretemp, Realtemp, and AMD overdrive will show you the most accurate value, and the accuracy of CoreTemp is often 5 degrees off.

So, I would always recommend that you use brand-specific in-house software for monitoring your CPU temperature no matter what the brand. There is no confusion on whether is Realtemp safe? Or Is AMD Overdrive safe?

Frequently Asked Questions

What is AMD Overdrive thermal margin negative?

Having a negative thermal margin on the AMD overdrive software is pretty alarming as it means your processor is no longer running at a safe temperature. The heat your CPU is producing has exceeded the theoretical max temperature.

What is processor thermal margin?

The thermal margin of a processor refers to the difference between the highest theoretical temperature that a CPU can function and the actual temperature of the CPU under current load.

What is a negative thermal margin?

When the temperature of the CPU crosses the theoretical temperature that the manufacturing company provided, a negative thermal margin occurs. A negative thermal margin indicates your CPU needs a new thermal paste or a better fan urgently.

Conclusion

Understanding thermal margin is essential especially if you have any interest in overclocking. In this article, I have extensively talked about what is the thermal margin. Hopefully, after reading the whole article, all the confusion regarding this topic would be resolved. Until next time, bye.

Нормальная ли это температура FX 8350?

Попробуй через hwinfo узнать температуру, аида не показывает выделенное значение.
На скрине мой 8300 в простое на бюджетной материнке, без термопасты (. ), но с кулером gammaxx 300

Смотри, чтоб у тебя были 2 главных кулера — один спереди внизу на вдув, один сзади на выдув. Если кулер на проце башенного типа, то на всякий случай проверь, чтоб сам вентилятор не стоял лопастями к задней стенке.
Ну и конечно же перепроверь термопасту и правильную посадку радиатора на проц, а то вдруг там проводок мешает и радиатор не прилегает плотно.

У меня подобная температура (около 60-65 градусов) была на процессоре AMD Phenom II x4 965 BE, когда на пластиковом креплении для кулера (которое прикручивается к материнской плате) с одной стороны сломался фиксатор и в итоге кулер с одной стороны был «колхозным» методом прикручен проволокой к этому пластиковому креплению, в первое же время термопаста накрылась медным тазом из-за такого «временного» решения, но увы, на тот момент взять термопасту и найти крепление было не где. С помощью такого «колхоза» я спокойно работал более полугода точно (на засохшей термопасте и кулере на половину прикрученного медной проволокой), пока не появилось в продаже то что мне было нужно, кстати процессор не тротлил и не сгорел, лежит себе отдыхает, ждёт пока куда нибудь его пристрою.

Так что у вас скорее проблемы могут быть в следующем: термопаста, плохой кулер, пыль в/на кулере, плохо настроены воздушные потоки вывода горячого воздуха из корпуса и поступления в него свежего воздуха, как в итоге в корпусе циркулирует воздух который постепенно становится всё горячее и горячее, что сказывается на повышении температуры процессора.

Не знаю что там с вашим кулером, сам лично себе башню ставил и 2×120мм куллера на вдув-выдув, выдув сразу на задний кулер, который подхватывал горячий воздух с процессора и выводил за корпус. Корпус старый, дешёвый, можно сказать офисный. Процессор не гнал, работает на частоте в 4гц и стандартном вольтаже (хотя можно было бы и понизить немного), так вот, в стресс тесте температура не повышалась выше 48 градусов, через первые несколько минут она подскочила до 48, далее долго держалась в этом диапазоне не повышаясь ни на градус, тротлинга не было. С уверенностью скажу, раз стресс тест показал 48 градусов в пике, значит и в тяжелых играх температура выше чем на 1-5% вряд ли поднимется.

Вывод: поставьте нормальный кулер и правильно «настройте» воздушные потоки внутри корпуса, чтобы вывод горячего воздуха из корпуса был максимально эффективен и чтобы в корпус попадал «не нагретый» воздух извне, это сделает ваш процессор «холоднее», а следовательно стабильнее и увеличит срок его эксплуатации.

Только посмотрев на цифру thermal margin ты поймёшь текущая температура нормальная или на пределе.

Начать нужно с того что посмотреть в штатной утилите AMD OverDrive параметр thermal margin, то есть запас в градусах до предела.
Конкретная температура которая показывается в разных утилитах не имеет особого смысла пока ты не убедишься что она правдива. В простое посмотри цифру thermal margin и отминусуй её от 61 градуса, получится реальная температура.

What is "processor thermal margin"?

i am guessing its the point at which the chip begains to throtle the speed and voltage.

possobly the utility takes room temp of which is

25c and adds the 58c to give you warning or shut off at 83 c which is little high — of coarse a pc i build was at 88c this morning i guess i should have taken the plastic off the windows vents

I like how Tom’s was quoted as a source for the definition.

I can’t image 52degC being a limit for ‘processor damage’. It feels like that could be a temp where the internal throttling may begin to take action. but CPUs are usually rated to ‘survive’ up to 100 degC. Our underhood microcontrollers are spec’d to operate up to 125 degC. but non-under hood chips might only be rated to 80-90 degC.

My Q6600 would get into the 70s during a Prime95 run, but a new cooler got it down in the mid 50s. Anyway, I’d prefer to keep it well below the 80s, but you shouldn’t see damage until you get into the 90s.

What is CPU thermal margin?

The Processor Thermal Margin is actually reporting the difference between Tjmax (the maximum theoretical safe temperature for the CPU) and the actual temperature of the CPU. So if the PTM is higher, it means your CPU temperature is much lower.

Is 50 degrees Celsius hot for a CPU?

Best CPU temperatures At idle, you should expect to see temperatures between 35 and 50°C (95-122F), and when playing games or running any apps which put a high load on the CPU, you should expect them to rise to 60-85°C (140-185F).

What celsius is dangerous for CPU?

But, as a generalization that might help you identify a serious problem, if you have an Intel processor, you could say that a CPU core temperature of over 40-45-degrees Celsius while idling and/or a temperature of over 80-85-degrees Celsius while under full load is probably a cause for concern.

Is 70C OK for GPU?

Yes, there are GPUs that can safely go over 90C without consequences (although it might shorten the lifespan in some cards). No matter the case, there are ways to keep the temperatures around 50°C-60°C and max 70°C when gaming.

What temp is bad for a GPU?

At what temperature should I worry about overheating? Consider 85°C the limit for standard GPU operating temps. Your GPU may exceed this limit while under severe stress, but it shouldn’t do so on a regular basis. The maximum operating temperature for any GPU is around 100 to 105°C.

Is 80 degrees Celsius hot for a GPU 3080?

GPU Safe Operating Temperature This means that, if you have an RTX 3080 your normal operating temperature range is anywhere between 40-50 degrees Celsius when idle and up to 80°C when under heavy loads (gaming or rendering).

How hot can an RTX 3080 GET?

Despite using quite a bit more power than any other Nvidia or AMD GPU, temperatures topped out at a maximum of 72C during testing and averaged 70.2C. What’s more, the fan speed on the RTX 3080 was lower than any of the other high-end GPUs.

How hot should my RTX 3070 be?

Some third-party cards will very likely stay above 2GHz while gaming. The RTX 3070 FE at stock runs pretty cool, reaching a peak temperature of 69C after a couple of minutes of gaming. The average temperature during our Metro testing was 66C, but note that the longer you game, the higher the average will get.

Is Undervolting bad for GPU?

You won’t damage your GPU by undervolting it, but you do risk losing a bit of stability. You’ll have to decide if the power savings and cooler operation is worth the slight risk of instability. If you do decide to undervolt your GPU, stress test it for a few hours to make sure it holds up.

Does Undervolting increase FPS?

Undervolting only improves FPS if your card isn’t maintaining it’s max clockspeed due to power or temp limits. It does lower power/temps/noise though, regardless of FPS effect, which is always welcome in my eyes.

Does Undervolting GPU increase FPS?

Undervolting alone will not lower a GPU’s performance, but it may decrease its stability – it could potentially cause some graphical artifacting or lead to a BSOD or failure to boot. Underclocking would lower your GPU’s maximum potential performance, but allow it to remain stable at lower voltages.
