With high-end or even mid-range gaming PCs, GPU (graphics card/chip) temperature is a serious concern. Hotter temperatures affect performance, and can make you sweaty if you’re using a laptop. In extreme scenarios, they can even burn your lap or cause a GPU to self-destruct. So what temperatures should you be aiming for, and how can you keep heat under control?
QUICK ANSWER
When playing you’re playing a PC game, a GPU should normally sit between 65 to 85C (149 to 185F). Idle temperatures typically sit around 30 to 45C (86 to 113F).
What’s a good (and safe) GPU temperature when gaming?
There’s no fixed answer to this question, since it ultimately depends on the chip/card design of your specific GPU. NVIDIA’s top-end consumer card, the GeForce RTX 4090, can handle temperatures up to 90C, or about 194F. AMD’s Radeon RX 7900 XTX is rated for as much as 110C (230F). That’s enough to boil water.
Realistically, those peaks are unsustainable and not what you’ll see in most gaming sessions, even if you’re playing a demanding 3D title like Cyberpunk 2077 or Half-Life: Alyx. More commonly you’ll see temperatures between 65 to 85C (149 to 185F), helped by efficient chip design and the massive cooling systems on modern graphics cards. 2D games tend to place less of a burden on GPUs, but still make an impact.
The cooler you can make a GPU run, the better. With sufficient cooling you can afford to overclock — that is, tune a GPU to run even faster than its factory default. There are software tools available for this, sometimes included with a card.
What’s a good GPU temperature when your PC is idle?
As with active gaming sessions, this is going to vary based on your exact hardware. Generally, though, you can expect temperatures between 30 to 45C (86 to 113F). That’s about as hot as a summer day in Texas.
What to do if your GPU temperature is high
Try these tactics to cope with unusual heat:
- Learn how to check and monitor your graphics card temperature. Usually, that means turning to Windows Task Manager or a GPU maker’s own software. Using the former, click on Performance, then your dedicated GPU.
- If temperature seems to be peaking for more than a few minutes, stop gaming right away. Let your GPU cool down, and explore the options below to keep things in check when you resume.
- With desktop PCs, make sure you have a well-ventilated case free of dust. You can use a compressed air can to get rid of the dust, but if your case isn’t built with good circulation, you may need to remove a panel, install more fans, or simply upgrade to a better case model.
- Check that your existing fans are working. PC fans are often quiet, so it can be hard to tell when they break.
- If you own a gaming laptop, buy a (sturdy) metal stand. That creates better heat dissipation in general, but most importantly underneath, where vents tend to be located.
- It sounds simple, but try to improve ambient room temperature. Aim a room fan at your PC, and block excessive sunlight by closing blinds or curtains.
- Consider installing a liquid cooling system if there’s space and your PC doesn’t already have one. Quality options aren’t cheap, but it’s better that than replacing a GPU that’s three or four times as expensive.
- Reduce or disable overclocking via software. Extra frames and graphics options aren’t worth the risk of losing a GPU entirely.
- If you’re comfortable with the technical skills involved, check your GPU’s thermal paste. No paste lasts forever, so you may need to apply more.
- Check your CPU temperature. An overheating CPU increases overall temperature in a PC.
