SpeedFan 4.52 beta 4 is online!
This beta has been compiled with Delphi XE2. The move from the almighty Delphi 7 has been done! The side effect is that
support for Windows 9x/Me has been dropped: now the minimum requirement is Windows 2000.
I will appreciate SEND REPORTs from SpeedFan's INFO tab from any system you are using, so that I can
validate the ton of changes
I had to apply to the source code. Preliminary tests seem to say that everything will
on every system :-)
This beta adds support for new hardware (including Intel Z170).
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 :-)
I just added my profile (almico) on
If you are on that network and you like SpeedFan I would really appreciate if you could recommend me as the Project Leader and Developer
at Almico Software.
What is it the Beta Program
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.

Beta Program Disclaimer
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.

SpeedFan.exe is digitally signed using my company's (SOKNO S.R.L.) certificate.
In order to run this beta, simply install SpeedFan 4.51, then replace the EXE (or put it in any temporary folder) and run it.
Please, use the SEND REPORT facility on the INFO tab to help me to evaluate the improvements I coded.
Tool to read ACPI TABLES 1.11 (15 apr 2010)
This tool has been superseded. SpeedFan 4.43 on will automatically send the relevant information.
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
