If you ’ve ever been playing a plot just o.k. and then found your fan spinning up tight and gimcrack and your frame rate tanking , you may have become a victim of thermal throttling . It ’s when your C.P.U. , graphics card , or some other component feels it ’s getting too hot to continue safely , so it lower its speed to keep itself hunt down and alive .
This sends frame rate right where you might expect : into the toilet . Want to learn more about caloric choking and how to prevent it ? Here ’s a niggling breakdown of what you need to know .

What is thermal throttling?
caloric throttling is when one of your system ’s components , most typically your C.P.U. or graphics card , attain its maximal secure operating temperature . At that point , a safety measure charge in to lower the power draw of that ingredient , thereby reducing its clock speed and operating temperature . This prevent the CPU or GPU from overheat and potentially causing price to its inner electronics .
Modern processorsand GPUs have more nicety in their throttling , so you may only see a pocket-sized cliff in their clock speed if they originate to overheat , while older designs could overleap to base alfileria , extend to a massive reducing in the raw performance of your system . That ’s still preferred to the chip becoming damaged from excess heat form - up , but modern boost algorithm and wise caloric management allow the late processors andgraphics chipsto perform at much closer proximity to their thermic thresholds for extended stop of time .
Although thermal strangulation is most widely notice among processors and graphics board , SSDs can thermally throttle , too , leading to a reduction in storage performance while the SSD cool down to more comfortable temperatures .
What does thermal throttling do to frame rates?
If you ’re play a biz and your graphics card or processor thermally throttle , you ’re sound to note — but it depend on the reason you ’re have that thermal throttling . If you ’re just using a high up - power processor that struggles with even high - end cooling , like theIntel Core i9 - 14900 K , then you might find oneself that you just see a few percent drop in CPU performance from its point , and that ’s about it . That might see you drop a few flesh per second , bet on your setting , but ultimately , not a huge quite a little .
However , if your CPU or graphics card is thermally throttling because their chilling is unequal , the thermal paste has go dry , your organisation is clog with junk , or the ambient temperature is too eminent , you could see a much more spectacular change . FPS can crater , so a smooth game take up to look like a slideshow , and in some cases , you might just see the plot or graphic driver crash . In the worst casing with runaway temperatures , your whole scheme might restart .
In myopic , thermic throttling will trim down your frame rate , potentially quite badly . It ’s definitely something you want to avoid if you could .
How can you prevent thermal throttling?
preclude thermic throttling is as simple as ensuring your components have adequate cooling , especially under sustained heavy load . However , that depends on the variety of workloads you ’re going to throw at your system . If you ’re just answering electronic mail and browsing the web , then your constituent are n’t going to work as hard as if you were playing games . If you ’re dally games , your portion are unlikely to work as hard as if you were transcoding video for 10 hour a Clarence Shepard Day Jr. . You ’ll also have unlike thermal considerations if you live in a hot part of the Earth or it ’s the summer .
With all that said , you want to begin strong and then keep your scheme well - maintained . That have in mind :
If you find that even doing all that does n’t prevent caloric throttling , then you ’ll want to consider undervolting or underclocking your components . That makes them head for the hills with less power , or at a lowly clock speed regardless of caloric throttling . This should help them obviate get hold of those higher temperatures in the first place .
How do you know if your CPU is thermal throttling?
Outside of your frame charge per unit or system wide performance falling , you could suss out if your CPU is thermal throttling by using an software to tail its temperature . There are several apps and computer program you could use tocheck your CPU ’s temperature , and most of them will include a small word of advice if your mainframe is hitting its thermic maximum . Most also include clock speed tracking , so you’re able to watch your MHz settle in material time .
Intel ’s XTUandAMD ’s Ryzen Masterwill also explicitly say you if your CPU is thermally throttling .
How to check if your graphics card is thermal throttling?
To break if your graphics card is thermal strangling , you need to look at its temperature . You cancheck your GPU ’s temperaturein Windows by await at the Performance check of the Task Manager . Alternatively , you could use third - party app , likeHWInfo , GPU - Z , orMSI Afterburner .
