HWiNFO for DOS, useful for legacy systems running DOS. Freeware and free distributable as-is. HWiNFO is an all-in-one solution for hardware analysis and monitoring supporting a broad range of OSes (DOS, Microsoft Windows 95 - Windows 11, WinPE) and platforms (i8086 - Xeon Platinum).

Is HWiNFO CPU and GPU temperature accurate?

Yes, HWiNFO data is reliable and accurate and will inform you about everything it possibly can about your computer. The information is split in 3 windows: a system summary, a full report, and active sensor readings.

Can HWiNFO control fans?

Technically, yes, HWiNFO shows you real-time data on hardware components and allows you to manually control fan speeds. However, you must use this feature carefully. HWiNFO was primarily designed to show system information. If you're looking to control CPU and GPU fan speeds you should take a look at SpeedFan or FanControl, which are specialized tools, both are free and have been tested extensively.

What are good alternatives to HWiNFO?

Two solid alternatives are Speccy and Open Hardware Monitor, which are also free and easy to use. You should also check out our feature about apps to analyze and monitor your PC.
