Feb 07, 2021 While most of us do not check the temperature or the fan speed of Macbooks as they are more or less silent. But once in a while, it is good to keep an eye on the temperature of your CPU, GPU, and also the fan speed. This is also useful if you are looking at some performance issues on your Mac.
Why Would You Need to Check CPU Temp?
The CPU is responsible for completing the instructions received from the hardware and software. When it’s too hot it can cause considerable damage to your device. It’s good practice to periodically check your CPU temp to ensure you aren’t inflicting any unnecessary harm on your device.
Your computer may be too hot because you’re overclocking your CPU. Overclocking is when you modify your processor to achieve higher performance than it was originally made for. This can cause your CPU’s temp to increase because it is being forced to work harder than the manufacturer intended.
If you own a thin computer, then you might notice it gets hot faster than other computers. Manufacturers have done away with fans on some new, smaller laptops. Though thin laptops may not have fans, they still have the same powerful processors which can overheat. Owners of these thin computers usually need to buy exterior accessories to cool their computers.
After using your device for many years, there may be dust buildup that stops the fans from cooling the CPU. Keeping your computer clean from dust can help extend its life by years. Perform regular checks on your computer’s parts to ensure the fans are clean. They may even need replacement parts to run more smoothly.
In addition to dirty or worn down parts, old computers run a higher risk of acquiring malware that can corrupt your device and steal your data. Download Panda Security’s free antivirus on your device to clean up any potential threats.
Sometimes a crash or shutdown has nothing to do with your software and hardware. It is the computer trying to protect itself. When a device has been running too hot for too long, your computer will turn itself off to prevent any further or long-term damage.
You may also notice that as your computer’s programs slow down when the CPU gets hotter. When you have a lot of information on your computer, the processor has to work harder to keep up with all of the information and it heats up faster than normal.
Decluttering your computer can help if you want to make your computer faster. You can do this by freeing up space on your RAM, hard disk, deleting old files and removing unnecessary programs.
How to Find the CPU Temp Manually
There are a couple of ways that you can manually check CPU. If you are a Windows user, you may be wondering how to check CPU temp on Windows 10.
Unfortunately, there is no easy way to check this, so you will have to opt to check your basic input-output system (BIOS). The BIOS is located on the motherboard and is the first software that starts when you power on your computer. It’s responsible for making sure all of the hardware in the device turns on and runs properly.
The BIOS can be found in computers from decades ago and is slowly being phased out. Many new PC’s operate with the Unified Extensible Firmware Interface (UEFI) software. This new software runs much faster and has fewer limitations. You can check your BIOS/UEFI software when you reboot your computer. As your computer restarts it will give you a designated key to access your processor settings (typically: F12, F2, ESC or DEL).
How to check BIOS/UEFI from advanced start menu in windows 10:
Step 1: Go to Settings in the taskbar.
Step 2: Scroll to Update & Security.
Step 3: Select Recovery in the side panel.
Step 4: Hit Restart now under Advanced startup.
Step 5: Select troubleshoot from reboot screen.
Step 6: Select Advanced options.
Step 7: Click UEFI Firmware Settings.
Step 8: Click Restart to confirm.
From here you’ll be taken to a screen where you can find what your CPU temp is under the PC Health Status or System Hardware Monitor.
How to Find the CPU Temp With An App: Core Temp
If you are looking for a fast way to check your CPU temp, it can be done quickly by downloading apps. There are apps to check CPU temp on both Windows and Mac devices. One of the most accessible ways to monitor the temperature of all your computer’s processors is with the Core Temp app.
Follow these steps to check CPU temperature with Core Temp:
Step 1: Open the application from your desktop.
Step 2: Locate the temperatures of your processors at the bottom of the widget.
Step 3: Maneuver to the bottom of your taskbar and select “show hidden icons” to quickly access core temps.
If you are looking to check CPU temp for macOS then you can download the Fanny Widget that allows you to monitor your fans and CPU temp right from your menu bar. For more control, you can even download SpeedFan, which allows you to manually control the speeds of your fans. For gamers and those wishing to access more information, you can download HWMonitor for a more detailed layout.
What’s the Best CPU Temp for Your Computer?
To keep your computer in the best possible shape, it is ideal that you keep your temps under 60°C. Anything under this temperature and your computer should be able to perform its best without inflicting damage to your computer.
If you find that your computer is consistently sitting between 60°C and 80°C, then it’s probably time for a cleaning. Check to make sure your fans are running properly and not hindered by dust.
Make sure that your processor is not reaching temperatures over 90°C. This will cause serious damage to your computer. If CPU temperature is high, look into replacing fans and reverting any overclocking adjustments you might have made.
5 Tips for Keeping Your CPU Temp Down
Keeping your computer free from any internal harm and external damage is the best formula for a long-lasting device. Try some of these tips and techniques to keep all of your parts in top shape:
1. Clean Your PC
There are a few ways to keep the inside and outside of your computer clean. You can use a dust rag and a disposable compressed air duster to keep debris off of the interior and exterior. You can also open the casing to carefully vacuum around the fans and other hardware components.
2. Replace Your Thermal Paste
There are times when an overheating issue can be easily solved by removing the old layer of thermal paste and adding a new one. This is what transfers the heat from your CPU to the cooler, and when it dries up your CPU temp can increase.
3. Purchase a New CPU Cooler
If you are still having trouble cooling down your computer, it might be time for some new fans with a new cooler. You can easily install a water cooling solution in addition to your fans, or even in place of them.
4. Use a Laptop Stand
An effective way to increase airflow and protect your device is to use a laptop stand. A hard and flat surface is the best way to keep your laptop free from suffocating. Laptop stands also hold your computer at the optimal angle for staying cool and user performance.
Macos Temperature Monitor
5. Keep Your Laptop Malware Free
Malware is software written for the purposes of harming you and your device. Malware can be used by governments to attack other foreign government systems. It can be used to spy on personal information, destroy files, make threats and send you advertisements. Installing antivirus software is the most effective way to keep your hard work and personal information secure.
If you have an old computer that is constantly running too hot, it might be time to perform some of these basic checks. Consistent monitoring of CPU temps can prevent early retirement of your computer. Unfortunately, if you cannot seem to lower the temperature no matter what you do, then it might be time for new parts or even a new computer.

I was recently looking for some tools to be able to view the Intel CPU utilization, frequency, and other information on macOS. In particular, my new Macbook Pro 16” is performing great with it’s Intel Core i9 CPU with 8 cores (and 16 threads), but I’d like to see how well it’s doing for myself. This article includes a listing and summary of the tools I found to do this with.
Activity Monitor / Intel MacCPUID / Intel Power Gadget / CPU Setter / Turbo Boost Switcher
macOS Activity Monitor
The Activity Monitor application is built into macOS, and it is pretty much equivalent to the “Performance}” tab of the “Task Manager” on Windows. In short it lets you see all the processes running on your machine, the CPU utilization, memory utilization, and a couple other things. With this app, there’s nothing to install and is available on all macOS machines.
You can also click on the Window menu and select options to view the CPU Usage, CPU History, and GPU History in separate windows. This will help give you insights into you current overall CPU utilization.
The above screenshot shows these 3 windows tiled. You can toggle their view individually and position them where you want.
MacCPUID is a developer tool used for displaying information collected from the microprocessor via the CPUID instruction. The CPUID instruction returns information in the general purpose registers such as manufacturer identification, a processor’s family, model, and stepping numbers, supported features (e.g. SSE, SSE2), cache information, and many others.
You can download it from here: https://software.intel.com/en-us/download/download-maccpuid
In the above screenshot, you can see the CPU Model of my Macbook Pro 16” as a Intel Core i9-9880H CPU @ 2.30Ghz. It’s also showing the AMD Radeon Pro 5500M GPU. Something interesting, is that even though this is an Intel made utility, it can’t determine the CPU Architecture for some reason. While not perfoect (I guess…) this utilizy does help show what CPU and GPU is currently in any macOS machine on the Intel hardware.
Intel Power Gadget
Intel® Power Gadget is a software-based power usage monitoring tool enabled for Intel® Core™ processors (from 2nd Generation up to 10th Generation Intel® Core™ processors). Intel® Atom™ processors are not supported. It is supported on Windows* and macOS* and includes an application, driver, and libraries to monitor and estimate real-time processor package power information in watts using the energy counters in the processor. With this release, we are providing functionality to evaluate power information on various platforms including notebooks, desktops and servers. Windows 7* and 32-bit versions of the Intel® Power Gadget for Windows* has ceased development from 3.0.7. Starting with version 3.5 and going forward, only the 64-bit version and Windows 8* will be supported.
You can download it from here: https://software.intel.com/en-us/articles/intel-power-gadget
You can see this utility shows us the Power usage, Clock Frequency, Temperature, and Core Utilization information for the machine. You can also use the Test menu to run tests of hitting the CPU and/or GPU to 100% utilization which is pretty nice to have.
CPUSetter adjusts the number of active cores in your cpu(s). It can also enable/disable hyperthreading on supported cpus.
To do this requires administrator access to the machine and a small privileged helper program is installed when you first execute CPUSetter.A convenient link to the system Activity Monitor is provided so you can observe the impact of changes.Authentication with your administrator credentials is required to make changes to your system.
The Processes window allows you to change the priority (nice value) of your processes, and to also limit the maximum CPU usage of any of your processes. You cannot adjust processes that do not belong to you.
You can download CPU Setter here: https://www.whatroute.net/cpusetter.html#download
While the CPU Setter utility is meant to help you control the Intel Hyperthreading feature of the CPU, it also has a really great view of System Stats. This utility that let’s you view additional information about the system that includes: Disk I/O, Wifi, Power usage, and more.
Turbo Boost Switcher
Turbo Boost Switcher is a utility that let’s you see the CPU tempeture, utilization percentage, and fan speed of you macOS machine. It’s main purpose is to let you disable the Turbo Boost feature of the Intel CPU in the machine. Disabling this basically prevents the CPU from increasing the clock speed above it’s base under high load, thus resulting in lower power usage and lower fan speed and noise. This can have an affect of increasing battery life with a little compromise in overall performance that is likely generally acceptable. It’s a nice utility to know about.
You can download Turbo Boost Switcher here: http://tbswitcher.rugarciap.com/
P.S. At the time of writing this I couldn’t get Turbo Boos Switcher to work on my machine… Dont’ know if it’s a compatibility issue with the app and the Macbook Pro 16” or something else. Could also be an app permissions issue. However, it’s still a neat idea and a utility I recommend you check out.
Macos Terminal Check Cpu Temperature
To close things off, let’s take a fun look at the Intel Core i9 CPU in this Apple Macbook Pro 16” maxed out to 100% CPU and 100% Integrated GPU. You can see all 16 thread are at 100% utilization, and the Intel Graphics 630 GPU is at 100% utilization as well.
There are other reviews available online on the overall performance of the Macbook Pro 16”. This wasn’t the purpose of this article, so I’m not discussing the specs and data shown in the screenshots.
This article is short and to the point. I wanted to show what tools you can use, and a brief look at what they offer. Mostly this is a list for my own reference so I can refer back to it in a year when I forget what tools I used. You can benefit from this being posted here, so it’s discoverable my anyone else, and hopefully somebody else finds this information useful too.
