thermal throttle
/ˈθɜːrməl ˈθrɒtəl/
CommonWhen a CPU or GPU automatically reduces its speed because it got too hot.
Often used to diagnose sudden performance drops. 'It's throttling' is a common diagnosis when a device runs fast briefly then slows to a crawl, especially on laptops.

| # | Example | What it means | Source |
|---|---|---|---|
| 01 | laptop was hitting 100C and thermal throttling in every benchmark. replaced thermal paste and now it's fine | The laptop was overheating and slowing down until the thermal compound was replaced. | reddit, 2024 |
| 02 | new gaming laptop thermal throttles within 5 minutes of loading a game. returning it | The laptop overheats so quickly it's unusable for gaming. | reddit, 2023 |
| 03 | fps drops from 120 to 40 mid-game? thermal throttle. check your CPU temps | The sudden performance drop is being diagnosed as a heat issue rather than a software problem. | reddit, 2024 |
| 04 | undervolted my CPU and thermal throttle is completely gone. stays at 95C instead of 100C | Reducing the CPU voltage lowered temperatures enough to stop the throttling behavior. | reddit, 2023 |
Use it when
- Describing a sudden performance drop caused by overheating hardware.
- Explaining why a CPU or GPU is running below its rated speed.
- Discussing cooling solutions that prevent performance loss from heat.
Do not use it when
- You mean general slow performance not related to heat.Use “bottleneck” instead.
- You mean a software-imposed performance limit.
Variations and related forms
Thermal throttle vs bottleneck
thermal throttle
Thermal throttling is a dynamic, heat-triggered slowdown that varies with temperature.
VS
bottleneck
A bottleneck is a structural performance limitation where one component can't keep up with another.
Origin and context
From hardware engineering, where throttling describes any mechanism that reduces output to protect a system. The specific term 'thermal throttle' became common in consumer hardware discussions as mobile CPUs and thin laptops made the problem more visible.
