SpeedFan is a freeware program that monitors fan speeds, temperatures and voltages in computers with hardware monitoring chips. SpeedFan can even access S.M.A.R.T. info and show hard disk temperatures too, if supported. What's News?

added detection and support for internal temperature sensors on multiprocessor AMD K8 (Sempron, Athlon 64 and Opterons) systems added full support for ADM1026 added full support for SMSC SCH311x added full support for MAX6640 added full support for INTEL 631xESB SMBus added full support for ADT7473 added LPC47M534 fan support ADT7473 and ADT7476 temperatures now properly handle offset 64 setting fixed W83637HF PWM MODE 3 and PWM 3 ENABLE setting fully verified DFI LP NF4 support added a check to skip SCSI disks that return invalid LOG SENSE pages (usually are EIDE/SATA disks where the driver tries to emulate some SCSI specific calls) added preliminary detection of NS PC8374L, NS PC87427 and WINBOND W83627DHG added an additional check in LM80 detection to avoid some false positives improved ICH7-M support added /NOAMDK8SCAN command line switch 100% fan speeds on program exit is no longer a default
