Prime95 essentially utilizes the CPU to find Mersenne prime numbers and in the process, generates a very heavy workload on the CPU.

If you’re not a fan of HWMonitor, or the system monitoring software simply isn’t working out for you, be sure to check out our article on the Best System Monitoring Tools for your PC. If this is the case, I’d highly recommend returning the laptop and choosing something else. Unfortunately some laptops aren’t designed properly to handle heavy loads for extended periods of times and may cross into the 100☌ level. Laptop CPUs are designed to run a little warmer, so a good rule of thumb on those is to keep temperatures under 95☌. While each CPU and GPU has its own maximum temperatures, a good rule of thumb is to keep desktop CPUs under 70☌ and desktop GPUs under 100☌. HWMonitor has a clean, easy to use interface and will provide real time information such as utilization, temperature, clock speed, and power usage of the onboard components.

One of the best free tools to monitor PC component temperatures is HWMonitor.
While some applications such as AIDA64 or Intel XTU will come with the ability to measure component temperatures, some of the other benchmarks don’t have this ability, which is why it’s important to have some sort of system monitoring software to ensure that your first run of Prime95 or Furmark isn’t burning up your brand new components. Without further ado, let’s take a look.īefore stress testing the system, the most important thing to have is some sort of way to measure temperatures of the components in your system. To help you test your system, today we’ll be sharing the best tools we use here at Gear Primer for stress testing everything in a PC new or old. Sometimes it’s difficult to detect small issues with newly installed RAM or how compatible a new motherboard is with the rest of your components until you load it up and ensure it’s capable of running 100% stable even during periods of heavy load. If temperatures are far below thresholds, then overclocking may be an option to improve system performance.įor older systems, it’s always recommended to stress test after any sort of PC upgrades as well. For those who want additional performance by overclocking, performing stress testing will also help give you an idea of how much thermal headroom is available as well. In order to ensure that there’s no hidden problems, the most important thing to do after buying or building a new PC is to stress test the machine for at least 6 hours to ensure the CPU, RAM and GPU are completely stable. You power on your new PC and it seems to be working fine, but you want to make sure it’ll also be perfectly fine when the system has Battlefield loaded at the highest settings while streaming to Twitch for hours on hours.
You’ve gone the whole nine yards making sure the entire system is cable managed to a tee, your bright RGB LEDs are installed in just the right spots, and there’s plenty of airflow flowing through the entire system. So you just spent days on days researching, purchasing, and/or building the perfect new gaming or workstation PC.
