Reviewed by: CNET Staff
This free program offers some useful system details to those savvy enough to understand its results. SpeedFan's tabbed interface isn't hard to navigate, but most users won't be able to make head or tail of the data this utility provides. The program's system-tray icon tells you the temperature of your PC's hard drive, and you can receive information on voltage and fan speeds.
The utility can display SMART data and includes a tool for resetting motherboard clocks. Basically, if this review makes no sense to you, SpeedFan is above your head and won't be worth downloading. However, PC technicians and those who like to do their own system maintenance might as well take a look at this application, particularly since it costs nothing.
Publisher's description
From Almico Software :SpeedFan monitors voltages, fan speeds, and temperatures in computers with hardware monitor chips. It can even access SMART information for hard disks that support this feature, and show hard-disk temperatures if that's supported. SpeedFan fully supports SCSI disks and can even change the FSB on some hardware (but this should be considered a bonus feature). At the lowest level, SpeedFan is a hardware monitor software that can access temperature sensors, but mainly it can control fan speeds (depending on the capabilities of your sensor chip and your hardware) according to the temperatures inside your PC, thus reducing noise and power consumption.
What's new in this version:
Fixed a bug where, after resuming from suspend, fan speeds were not really changed; Added full support for AMD CD5536 SMBus; Added identification of Fintek F75111R; Fixed an Exotics tab Access Violation; Fixed a bug that caused all of the EVENTS to be lost after entering CONFIGURE.

Version: SpeedFan 4.37
"DOes not read AMD 3 core correctly"
Pros: It is free.
Cons: On my 8450 reported core temps at 34C,41C and 89C. AMD overdrive reports 30.5,30.5,30.5.
Summary: If this program reports bad results, get a second opnion before investing money in repairs/new gear.

Version: SpeedFan 4.37
"Useless for core temps on Core i7 965 XE CPU"
Pros: Has numerous useful sets of information included, particularly SMART information from hard drives.
Cons: The temperatures shown are much lower than actual core temperatures. BIOS temp readings, CoreTemp, and HWMonitor line up within a few degrees of one another. SpeedFan shows temps that are ~15 degrees C lower. Dangerous if you rely on it!
Summary: Don't use this as your sole source of temperature information if you have an Intel i7 965 XE cpu. If you overclock, don't use it at all. You could burn up your CPU.
