This post attempts to provide you with a comprehensive solution to fix the CPU temperature jumping up and down problem that may be affecting your PC. Have your fans ever started spinning erratically while you were using your computer and then became silent? Do you have a program that displays the CPU temperatures changing quickly? Is this a significant issue, or is it unimportant?
It can be very aggravating when the CPU temperature of your computer starts to fluctuate erratically for no apparent reason because CPUs are not intended to operate at high temperatures for extended periods. You may not know what the issue is or how to resolve it.
Be at ease; we are here to assist. In this post, we’ll examine some of the most frequent causes of CPU temperature fluctuations and provide solutions. If your CPU begins to run hot, you must comprehend what is happening. Here are several potential causes of excessive CPU heat and some steps you may take to help stop it from happening again.
CPU temperature jumping up and down:
Even if you aren’t running any app, most of the time, it’s not a major deal if your CPU temperature is fluctuating erratically. That is a result of background processes that heat the CPU. The temperatures soon return to normal after they stop running, which may seem to be a strange variation.
Reasons and solutions for CPU temperature jumping up and down:
Update BIOS and Chipset Drivers:
Updates to the BIOS and chipset drivers may offer more support for more recent hardware or technologies, perhaps resolving any issues with CPU overheating. To keep your computer current, regularly check for fresh updates. In certain cases, outdated drivers are to blame for CPU temperatures greater than usual, so check for updates on all of your hardware components regularly.
Too Many Applications Running At Once:
It goes without saying that when computers are working hard, they become warm. Try dismissing some of the applications you’re not using if you see the CPU temperature fluctuating. This will allow the CPU to cool off and free up some resources.
Overclocking Your CPU:
Just be aware that there is a danger of potentially permanent damage if you overclock your CPU too much. Before considering overclocking to increase performance, make sure that the entire computer’s hardware has been completely cleaned and checked for appropriate seating.
Replacing Hardware with “Hotter” Models:
The temperature may be higher partly because your video card or RAM modules have recently been upgraded to ones with better specifications. Make sure you have taken the necessary precautions to account for and disperse any additional heat that these new components may produce (better cooling system, more fans, better CPU cooler, better case airflow, etc.).
Lose Contact Between CPU and Heatsink:
This frequently results from the accumulation of thermal paste over time. Too much thermal paste can create a barrier between the CPU and the heatsink, hindering heat dissipation. If this is the case, you can try using a cotton swab and some isopropyl alcohol to remove the old thermal paste and replace it with a new layer. Avoid damaging your motherboard or CPU at any cost!
Improperly Seated Hardware:
Everything within the chassis intended to be cool, including the CPU, GPU, and RAM modules, can become quite warm. If the thermal paste is already installed, ensure you are using none (or not enough) of it. And your CPU isn’t swaying around inside its socket—this can seriously obstruct airflow!
Ensure that each component is firmly inserted in its appropriate slot on the motherboard. Do not be afraid to remove and reinstall any hardware that appears to be loose. You should acquire a CPU clamp to lock the heatsink in place if there is no hardware issue (you removed it to upgrade, for example).
Overheating Due To Age:
Since computers are not made to operate at high temperatures for long periods, they may eventually begin to overheat. If your computer is older than a few years, this could be the reason why your CPU temperature fluctuates.
Check The Airflow In Your Case:
People frequently ignore this approach because they believe a computer’s airflow should be self-explanatory. Poor airflow may be a contributing factor if your CPU temperature is fluctuating. Check to see if the computer’s internal fans are functioning properly and performing their intended function in this instance.
Test any of them on a different system to verify sure they aren’t broken or if they appear to be spinning very little or not at all. It’s also important to make sure your computer isn’t on a carpet because that could be obstructing certain vents. Checking whether the room temperature is too high is the final step.
As they run, computers produce a lot of dust, which collects on the case’s outside and interior surfaces. This dust will ultimately find its way into every crevice until it accumulates to a point where airflow is obstructed. Some players opt to perform thorough cleanings of their cases at least twice a year.
Your computer’s cooling system relies heavily on fans, but they are not infallible. Verify that each of your fans is rotating freely and isn’t emitting any odd sounds. Make sure all of your fans, if you have any, turn in the same direction (an arrow on the fan usually indicates this).

Frequently Asked Questions
Is 80 degrees Celsius hot for a CPU?
Generally speaking, playing video games with a CPU temperature of no more than 176°F (80°C) is safe. However, keeping your CPU temperature below 167°F (75°C) is preferable if you are worried about overheating or want to maximize performance.
Why my temperature goes up and down?
Your body temperature changes throughout the day as you move, eat, drink, interact with others, and change your surroundings. Because there is such a wide range in temperature throughout the day, it is ideal to take your temperature at night, when your body is steady, to assess your general health.
How long will a CPU last at 80C?
It may continue for another ten years. How long will my CPU run at 5GHz after being overclocked from 3.9GHz? One more of those prediction-related queries without a meaningful solution. Although it is hot by Intel’s standards, there is no evidence that it will self-destruct in less than six months.
Is 78c OK for CPU?
So, the Core temperature’s nominal working range is as follows: Not recommended are core temperatures more than 85°C. Ideal core temperatures are under 80 °C. The ambient (room) temperature affects both the rise and fall of core temperatures.
