What Happens if You Undervolt Your CPU?

If you use your PC for intense gaming, then you have might have faced heating issues with your CPU. There are numerous ways to cool down your CPU, such as buying a fan or water cooling kit. But one method people are skeptical about opting for is undervolting their CPU.

Before going too in-depth, let’s first have a look at what undervolting your CPU means for your PC.

What Does Undervolting a CPU Do?

In layman’s terms, undervolting a CPU means to decrease the voltage reaching the processors in CPU. By doing so, you can drastically cool down your CPU.

However, less voltage might result in a slight drop in the performance and the lifespan of the processor.

If you’re facing constant heating issues even after implementing this method, then you’d be wise to get it checked with a professional, as there may be a chance there is severe hardware damage rather than just a dusty cooling fan.

What Happens When You Undervolt Your CPU?

Now you might be probably wondering is this process safe or not? Well, no need to worry as this process is 100% safe, and the worst scenarios which might result is that your PC could crash and reboot.

But the chances of it happening is highly unlikely. Also, undervolting a CPU is quite an easy process so, you won’t need any professional help in doing so.

Pros and Cons of Undervolting Your CPU

Well, just like any other technical process, there are always positive and negative aspects of it. And, in this case, you should keep a few things in mind before moving ahead.

That being said, let’s have a look at the advantages and disadvantages of undervolting your CPU:


  • Lowers heat: Undervolting your CPU will reduce the temperature of the CPU and keep it cool while gaming or continuous usage of the PC.
  • Less Power Consumption: Undervolting will also have an impact on the power consumption of your PC. Thus, it could save you a few bucks on your electricity bill!
  • Easy Process: As we mentioned earlier, undervolting a CPU doesn’t involve a complex process, and anyone can easily do it by reading a few instructions. There are even a few trusted softwares that can guide you through the process, such as Throttlestop.


  • Lower Performance: If undervolting a CPU cools down the CPU, it just won’t work as hard as it does when it’s heated–think about it in terms of a car engine. A cold engine has much less strength than a warm engine does.
  • Instability: Cutting the recommended voltage from your CPU could lead to theinstability of the PC altogether. You might face a few stuttering components here and there.

Is it Safe to Undervolt Your CPU?

This question will definitely pop in your mind when considering undervolting your CPU, but there’s little reason to worry as undervolting is generally a safe process.

However, as we discussed earlier, you might face a few instability problems until you’ve clocked it to a workable threshold.

So, we hope now you have no doubts about the results of undervolting your CPU.

In the end, whether you’d rather have a high-performing PC but face heating issues, or a lower-performing PC with a cooler CPU is entirely up to you. All you have to do is strike the right balance and you’ll be well on your way to clocking a great PC.
