To get CPU usage, periodically sample the total process time, and find the difference. You subtract the kernel times (for a difference of 0.03 ) and the user times ( 0.61 ), add them together ( 0.64 ), and divide by the sample time of 2 seconds ( 0.32 ).

If most of your computer activity is spent idle, anything 0 – 100% on the occasional peak for background services would be acceptable at any given time and the measured average will alternate. When running stressful tasks, anything 70 -100% will be expected for an average depending on your setup.

If its 70C under full load, then no problem. It’s a bit warm, but perfectly safe. There is no way heat can damage your chip these days. This chip has a max temp limit of around 100C, and the chip will start throttling down when it reaches that temp.

AMD processors generally do run warmer than Intel processors but Intel processors can get hotter. AMD’s CPU temperatures are more or less consistent while Intel CPU temps can vary from system to system.

No matter the case, a CPU temperature should play around 75-80 degrees celsius when gaming. When the computer is doing small processes or in an idle state, it should be around 45 degrees celsius to a little over 60 degrees celsius at most.

The CPU can typically handle up to like 100 degrees C, but if it ever reaches that point, it will start thermal throttling. Regardless, having temperatures this high will shorten the lifespan of the CPU.

85C is perfectly safe, even for 24/7 long term use.

It’s known that 90 C and lower is considered “safe” but everyone doesn’t have the same guidelines. I’d say that anything above 95 C is not good at all and it’s true that your CPU will throttle or BSOD to prevent meaningful damage but generally, you want to keep your CPU running cooler to preserve the lifespan.

Your processor shouldn’t be hotter than 75°C/167°F, nor significantly colder than 20°C/68°F. There are numerous things you can do to keep your PC cool, including: Keep your PC well-ventilated. Clear dust from vents and fans.

If your CPU briefly just so happens to hit 95°, it isn’t going to cause catastrophic failure, but if it is around 95° frequently or for long periods of time, this is very, very bad. 85° should be the limit, and you really should not go above that.

Is it safe to have your CPU under full load and the CPU usage at 100% for 3-4 hours? So long as you have proper cooling, yes. I’ve run our servers at 90-100% for weeks at a time doing load tests.

Here’s how it’s done.

1. Right click the Start menu and select Control Panel.
2. Click Hardware and Sound.
3. Select Power Options.
4. Find Processor power management and open the menu for Minimum processor state.
5. Change the setting for on battery to 100%.
6. Change the setting for plugged in to 100%.

It is built to run at 100% utilization,so it should be safe,unless you are pushing the limits too much. Even mining GPUs last years spending all the time at 100%. But running at 100% definitely affect its life span, the transisitor wear out on usage. Still it will run for years unless you are unfortunate enough.

System Cooling Policy

1. Click the Start button and click Control Panel.
2. Click Power Options.
3. Click Change Plan Settings.
4. Click Advanced Power Settings.
5. Expand the Processor Power Management list.
6. Expand Minimum Processor State List.
7. Change the settings to 100 percent for “Plugged in.”
8. Expand System Cooling Policy List.

7 Answers. High CPU usage by the “System” process can often be caused by a hardware driver issue (bug, old version, incompatility etc). The System process loads (or hosts) multiple hardware drivers from different vendors that require higher level of memory access.

Viruses: If you notice extremely high CPU usage of nearly 100 per cent but can’t find a cause, a virus or other type of malware may be causing it. Viruses are often invisible in popular monitoring tools. If you suspect a virus, you should immediately check your computer with an anti-virus program or malware scanner.

The easiest solution I found is to limit Processor power.

1. Go to Control Panel.
2. Hardware and sound.
3. Power options.
4. Edit plan settings.
5. Change advanced power settings.
6. Processor power management.
7. Maximum processor state and lower it to 80% or whatever you want.

Press Ctrl+Shift+Esc to launch Task Manager, then, click the Processes tab and choose “Show processes from all users”. You should now see everything running on your PC at the moment. Then click the CPU column header to sort by CPU usage, and look for the process that’s the most demanding.
