Last updated:
A GPU is too hot when its core temperature goes above 90°C, or its hotspot (junction) temperature goes above 105–110°C on AMD cards. At these temperatures the GPU reaches its rated maximum and starts thermal throttling. For long gaming sessions, the ideal GPU temperature stays below 85°C.
What GPU temperature is too high?
A GPU temperature is too high when it reaches the card’s official maximum temperature. The table below shows 5 temperature bands for GPU core temperature under load:
| GPU core temperature | Status | What happens |
|---|---|---|
| Below 80°C | Good | Full boost clocks, quiet fans |
| 80–85°C | Warm but normal | Full performance on most cards |
| 85–90°C | Hot | Close to the throttle point on NVIDIA cards |
| 90–95°C | Too hot | Thermal throttling, lower frame rates |
| 95°C+ | Danger zone | Crashes or emergency shutdown |
What is the maximum temperature of current GPUs?
The maximum temperature of current GPUs is 85–90°C for NVIDIA GeForce cards and 110°C hotspot (junction) for AMD Radeon cards. These are NVIDIA’s and AMD’s official limits:
| GPU | Official maximum temperature |
|---|---|
| RTX 5090 | 90°C |
| RTX 5080 | 88°C |
| RTX 5070 Ti | 88°C |
| RTX 5070 | 85°C |
| RTX 5060 Ti | 87°C |
| RTX 5060 | 89°C |
| RTX 4060 to RTX 4090 | 90°C |
| Radeon RX 9000 and RX 7000 series | 110°C junction (hotspot) |
The complete list is in the GPU temperature chart by model.
What happens when a GPU gets too hot?
A GPU that gets too hot goes through 4 stages of protection and damage:
- Thermal throttling: the GPU lowers boost clock and voltage to stay at its maximum temperature, so frame rates drop.
- Instability: overheated memory or core causes crashes, black screens and GPU artifacting.
- Emergency shutdown: the PC turns off when temperature keeps rising past the safe limit.
- Faster wear: years of high heat dry thermal paste, wear fan bearings and stress solder joints.
Modern GPUs protect themselves, so a single overheating event rarely causes permanent damage. Running at the throttle point every day costs performance and shortens component life.
What are the signs of an overheating GPU?
There are 5 common signs of an overheating GPU:
- Frame rate drops after 10–20 minutes of gaming, not at the start.
- Fans run at 100% and sound loud.
- GPU clock speed falls while temperature sits at the maximum.
- Random crashes, black screens or restarts during games.
- Flickering, colored dots or lines on screen.
To confirm overheating, check your GPU temp with HWiNFO, game for 20 minutes and read the Maximum column.
How do you fix a GPU that runs too hot?
You fix a GPU that runs too hot with these 8 steps, ordered from easiest to hardest:
- Confirm the fans spin under load. A stopped fan is the most common cause; see GPU fans not spinning.
- Clean the dust from the heatsink, fans and case filters with compressed air.
- Improve case airflow with at least one front intake fan and one rear exhaust fan.
- Set a custom fan curve in MSI Afterburner so fans speed up earlier.
- Undervolt the GPU to cut 5–10°C with little or no performance loss; see how to undervolt a GPU.
- Cap the frame rate to your monitor’s refresh rate.
- Remove any overclock, because overclocking raises power and heat; see what overclocking a GPU does.
- Replace thermal paste and pads on cards older than 3–4 years, or when hotspot reads more than 25–30°C above core.
How hot is too hot for GPU memory?
GPU memory is too hot above about 100–105°C memory junction temperature. GDDR6X and GDDR7 memory normally runs at 80–95°C under load. Fresh thermal pads or extra airflow over the backplate lowers memory temperature.
FAQ
Is 90°C too hot for a GPU?
Yes, for most NVIDIA cards 90°C is the maximum rated temperature, so the GPU throttles there. It is not instantly harmful, but cooling should be improved.
Is 85°C safe for a GPU?
Yes. 85°C is within the official limit of nearly all current GPUs, though it leaves little headroom.
Is 60°C too hot for a GPU while gaming?
No. 60°C is a cool gaming temperature; see is 60°C too hot for a GPU while gaming.
Can overheating permanently damage a GPU?
Rarely. Modern GPUs throttle and shut down before heat damages the chip, but long-term high heat shortens the life of fans, pads and memory.
