SpeedFan 4.34 Final is online! A new beta should appear next week, after I have made sure that everything is working fine with this final. Thank you to all the beta testers that helped me a lot to make SpeedFan a better product.

Don't forget that you can upload your configuration by using this link. I would really appreciate if experienced users with nicely working configurations could find 30 seconds to upload their configurations to help other users :-)

Every now and then I create some bleeding edge versions of SpeedFan, or of some other softwares (always related to SpeedFan), to receive feedback from the users. Such programs try to access new hardware or try to investigate new ways to read available data. Before going into the mainstream SpeedFan, I need to make sure that everything works fine and that nothing else is broken. Everything I post here has been previously tested on my very own computers.

All the downloads posted here should be considered experimental. Everything was previously tested on my own hardware and on my production computers. This means that you can trust me when I say I did my best not to hurt anything. Nonetheless, a beta software might hurt your hardware and you might lose your data. Always close other programs prior to running anything you download from here and backup your data. You should try these programs only if you know what you are doing and if you are willing to help me by sending your feedback.

Because of the nature of this area, you are not allowed to mirror these files. These files change often and this page includes important info about their usage and the eventual problems they might cause. I'm spending a lot of time helping users that didn't download the beta from here and this can't be my main task. Furthermore, these files are accessible only to registered users. Publishing them on any other page is strictly forbidden. Feel free to let your readers know about these betas, but simply point to this BETA PROGRAM page. Thank you for your cooperation.

Tool to read ACPI TABLES 1.08 (24 jul 2006)

This program reads ACPI tables from your computer. There is no secret in them and no sensitive data is trasmitted. Your reports will help me to better support your hardware. Reports from notebooks and branded computers will be greatly appreciated. In order to run this tool, you simply need to have the latest SpeedFan installed. This tool is safe to run.
Version 1.08 removes a range check error that the compiler produced with no real reason.

Program to attempt to set AAM on hard disks that support it 1.01 (15 dec 2004)

This software tries to understand which OS and which drivers do support the relevant calls that need to be done in order to set AAM (Automatic Acoustic Management) on modern hard disks. It works only on NT class operating systems. I'm not sure if it works on NT too, but it works for sure on Win2K. Unzip, run and then use the integrated facility to send me the report. Please, send me reports even from systems where it doesn't seem to work.
Version 1.01 now properly identifies hards disks where AAM is available, yet disabled, and goes on with the test.

Program to access SCSI HD temperature and reliability data 1.13 (18 feb 2004)

Even if, since version 4.21, SpeedFan includes full support for SCSI drives, this tool is still useful as it allows me to see more data from SCSI drives. With the help of your reports I can try to find and show new info about your SCSI drives. This tool never caused any harm to any system and its low level code was included in the mainstream release of SpeedFan.
