Hey folks,

I was wondering if anyone can explain why my laptop overheats when using Windows (any version), but when using Linux (Ubuntu) I have no heating issues!

Its not a major worry as I have recently moved over to Linux as my main system, but I am curious why this is happening.

Thanks in advance,

Cybrix

Short answer: different power-management and driver behavior is usually the cause. and pointed toward drivers and background work; the practical difference is that Windows and Linux often choose different CPU/GPU power profiles, fan/thermal handling, and scheduled tasks — so the same hardware can run noticeably hotter under Windows even though the machine itself is fine.

Concrete diagnostic and quick fixes

  1. Check what’s running: open Task Manager (or Process Explorer) and sort by CPU, Disk and “Power usage.” Identify any anti‑virus, indexing, updater, or vendor utilities spiking resources.
  2. Power plan and cooling policy: Control Panel → Power Options → Change plan settings → Change advanced power settings → Processor power management. Set Minimum to a low value (5%), System cooling policy to Active, and set Maximum to 99% to avoid turbo frequencies if temperatures are high.
  3. GPU and driver power modes: update chipset and GPU drivers from the laptop maker (or NVIDIA/AMD) and set GPU power management to “Adaptive/Optimal” rather than “Maximum performance.”
  4. Clean boot: use msconfig to hide Microsoft services and disable non‑Microsoft services/startup items to see whether a vendor background service is responsible.
  5. Monitor temps in Windows with HWInfo/CoreTemp while repeating an identical workload in Linux (or with a short stress test) to compare exact clock speeds and which device (CPU vs GPU) is heating.

Advanced notes and cautions

  • BIOS/UEFI and vendor thermal drivers (Intel DPTF, Optimus, OEM power utilities) can change fan curves or turbo behavior; update firmware if available.
  • Undervolting or changing CPU limits can reduce heat but may affect stability and warranty—treat as advanced.
  • If Linux is cool under identical sustained load, a software/configuration cause on Windows is very likely; if Windows remains hotter after the above checks, focus on vendor drivers, scheduled services, and BIOS/fan profiles.

This complements ’s and ’s points with targeted checks and safe, reversible changes to locate and fix the Windows‑side cause.

Windows has massive overheads compared to a Linux based operating system, that would be the simple answer.

In Windows, almost everything runs on the GUI which means you are use a huge amount of resources to do very simple tasks.
Unlike Windows, in a Linux environment you have a lot which runs on what is known as a daemon, running in the background. This means that only things that you run are running on the GUI.

On the other hand, some find Linux runs hotter because drivers for hardware isn't optimised, unlike that on Windows. This is because hardware manufacturers normally focus on the main market (Windows) and often neglect drivers for other OS, which is why you normally rely on open source drivers for a Linux computer.

it is because more process are running on the background. Try to remove all unnecessory softwares from startup. And you may find some difference
