Program Category: CPU Information/Overclocking



SpeedFan is an hardware monitoring software that is able to change fan speeds according to system temperatures. SpeedFan can read S.M.A.R.T. values (and temperatures) from your hard disks and change the FSB speed.

Version 4.34:

• added full support for SiS964 SMBus
• added full support for SiS966 SMBus
• added full support for ULi M1575 SMBus
• added full support for VIA VT8237S SMBus
• added full support for VIA VT8251 SMBus
• added full support for nVidia MCP61 SMBus
• added full support to read internal temperatures on AMD K10 processors
• added native nVidia video card (up to, but excluding 8xxx) internal temperature reporting
• added full support for SMSC SCH5307
• added full support for F8000 temperatures and fan speeds
• added full support for SMSC EMCT03
• added full support for WINBOND W83793G, including ADVANCED options
• added support for Fintek F71782F hardware monitor at unusual addresses
• added support for Winbond W83627DHG at unusual addresses
• added support for ITE IT8726F hardware monitor at unusual addresses
• added support for a new stepping of the Andigilog aSC7621
• Winbond W83791D properly handles higher fan divisors for fan1, fan2 and fan3 and shows fan4 and fan5 too
• added SMSC LPC47M192 FAN DIVISOR settings in CONFIGURE / ADVANCED
• added full PWM support to SMSC LPC47B397, including settings in CONFIGURE / ADVANCED
• CONFIGURE now allows to go as low as -60C when selecting the DESIRED and WARNING levels to let users of the RELATIVE Intel Core temperature reading properly configure SpeedFan
• improved DDR2 memory module size detection
• added preliminary DDR3 identification
• new icon by Bengt Strom
• fixed an issue where Intel Core temperatures on multi core systems reported the same temperature for all cores
• improved Tjunction detection for Intel CORE temperatures (you might no longer need the temperature offset in CONFIGURE / ADVANCED)
• fixed crash on several DFI motherboards
• fixed the detection of older revisions of the ITE IT8705F
• restored the correct clock speed after resume from hibernation
• rewritten the logic of the usage of a synchronizer in the thread that reads CPU usage (this will fix the SpeedFan not exiting issue)
• address $2E on DFI motherboards is no longer scanned if the motherboard model starts with LP. If you have one of these models and you know that there should be a valid chip at that address, send me a SEND REPORT (INFO tab) with some NOTES
• fixed ADT7475 temperature readings when in offset 64 mode
• fixed a bug when changing the type of data to be charted
• mails sent by SpeedFan now properly separate headers and the body with a blank line
• fixed an issue with SUN 2864 motherboard

Thanks, good info, I was having some issues with the 4.28, kinda slow start.

can you tell me what those temps represent?
Temp 1, Temp 2 and Temp 3.

If you hit F1 when you have the speedfan window open, it will take you to his help files. They are pretty good.

Differs from each mobo, usually the highest temperature is your CPU, the lowest one your mobo and the middle one PSU/PWM.

If you have one that gives an abnormally high info, you should just disregard that, because it's your motherboard that doesn't read the PSU temperature/the PSU doesn't have a thermometer in it.

Does that apply for AUX also? I don't know what AUX represents but I'm getting readings of 130*c, while every other temp is fine.

v!p3r^

hmm my temp 1 says -55c and my temp 3 says -1 and my temp 2 says 22? im lost

v!p3r^

anyone?

gonX

If anyone have any abnormally high or low temps, please disregard them.

The AUX displayed further up is a good example, it's simply just because the sensor doesn't get any data so it "guesses" or so what I've heard.

Also v!p3r^ > Please use PC Probe from ASUS instead of Speedfan, because ASUS doesn't support Speedfan (or is it reverse?)

The newest version of the program is supposed to handle things somewhat better than in the past, particularly when it comes to core temps on C2Ds. The best way to "calibrate" speedfan temps is to run them along with another comprehensive program such as Everest that provides more info. Once you figure out the meaningful temps, you can disable the garbage ones. I believe you can also rename temps, though I may be mixing up programs.
