Huge List of Computer Stress Test Software [Used by Engineers in the Rugged Computing Industry]

SpeedFan[27] (FREE)

The best way I can describe this little yet powerful tool is to list what the actual website states, which is true to its core: “If you need a tool that can change your computer’s fan speeds, read the temperatures of your motherboard and your hard disk, read voltages and fan speeds and check the status of your hard disk using S.M.A.R.T. or SCSI attributes, then you came to the right place.” The website is quite difficult to navigate through, but make sure to click the hyperlink that says “SpeedFan 4.52” to download.

Open Hardware Monitor[28] (FREE)

To see temps, volts, fan speeds, load and clock speeds of your computer for free – this is the tool for you. Very easy to install and even easier to use. It reminds me of an old-school utility tool from XP times but it just makes sense. Everything you need to know on one screen.

WiFi Debugging Tools

TCPDump[29] (FREE)

A powerful command-line packet analyzer; and libpcap, a portable C/C++ library for network traffic capture.

For main features and commands, take a look at this cheat sheet[30].

iPerf[31] (FREE)

iPerf3 is a tool for active measurements of the maximum achievable bandwidth on IP networks. It supports tuning of various parameters related to timing, buffers and protocols (TCP, UDP, SCTP with IPv4 and IPv6). For each test it reports the bandwidth, loss, and other parameters. This is a new implementation that shares no code with the original iPerf and also is not backwards compatible. iPerf was orginally developed by NLANR/DAST. iPerf3 is principally developed by ESnet / Lawrence Berkeley National Laboratory. It is released under a three-clause BSD license.

Eye P.A.[32] (FREE & PAID)

Eye P.A. is a rapid 802.11ac packet capture and analytics solution that makes WiFi traffic visible for quick analysis and diagnosis. At a glance, you can find and fix packet loss, monitor channel capacity, minimize congestion, and shed light on network configuration and security issues.

Chanalyzer + WiSpy[33] (FREE & PAID)

WiFi is no longer a luxury. Your users depend on WiFi for business, education, healthcare, and entertainment. But delivering reliable WiFi in complex network environments can be difficult. That’s why we built Chanalyzer Essential – a bundle that includes Wi-Spy DBx, Chanalyzer + Report Builder, and Device Finder 2.4 GHz Directional Antenna.
