HCI MemTest vs Notebook FanControl

HCI MemTest checks whether a computer can store and retrieve data from memory reliably. Its maker recommends running it after buying a computer, installing RAM, or changing the system configuration, including overclocking. The free MemTest download is Version 7.0 for Windows 9x, XP, 7, 8, 10, and 11; the product listing also names Linux. MemTest Pro adds controls for the number of threads and RAM assigned to each, plus summaries of results and total throughput. Pro also supports command-line automation, saves error logs to disk, and can test memory in the background while the computer is in use. Deluxe includes Pro and adds a 64-bit bootable CD or USB version that accesses all RAM without loading an operating system. That boot option requires CSM or legacy BIOS support. The maker recommends 100% coverage for most errors and around 400% for intermittent failures. The FAQ cautions that software cannot reliably identify a failing physical chip; testing modules one at a time may help isolate a faulty board. The free download can be unzipped into a folder and removed by deleting its contents. Free use is available; MemTest Pro costs $5, paid once, and Deluxe costs $14, paid once.

Notebook FanControl (NBFC) is a free, open-source service for controlling notebook fans on Windows and Linux. Its configuration system adapts the service to many notebook models. Windows users run an installer, choose a notebook configuration, and apply it so NBFC can control the fans. Linux users build the software themselves, install its systemd service, and apply a notebook configuration; the project provides no pre-built Linux releases. Downloads are linked through GitHub releases and a Chocolatey package. The repository includes the GNU General Public License version 3. An FAQ points to a supported-notebook list and says a configuration for a similar model may work when yours is absent. The maintainer does not create individual configurations, so users may need to make one themselves. Some systems have conflicts with ImDisk Toolkit or HWiNFO. Nvidia Optimus notebooks may lose fan control while the dedicated GPU is active, and Linux Secure Boot can require disabling.
