![]() SpeedFan can find almost any hardware monitor chip connected to the 2-wire SMBus Serial Interface and to the ISA BUS. The most used are National PC87366 and all of SMSC LPC SuperIO chips. SpeedFan can automatically detect them and use their features. Some SuperIO chips include temperature sensors too. One nice aspect of Afterburner is that it shows the maximum value reached for the various sensors, so you can see that the GPU clocked at up to 1980 MHz, for example, while the temperature peaked. Winbond W83697HF, Analog Devices ADT7463, SMSC EMC6D102, ITE IT8712F, National LM85C and Maxim MAX6650 are very good candidates. If your BIOS was programmed to setup such chips this way you can still try to use SpeedFan's Advanced Configuration to revert to manual (software controlled) mode. Some chips can even be programmed to vary fan speeds without any additional software intervention. From one of the very first hardware monitor chips that could be found in standard PCs, the National Semiconductor LM75 (and all of its clones, like the Philips NE1617 and the Philips NE1618 or the Maxim MAX1617) or the Analog Devices ADM1021, such chips have been greatly improved, both in their precision and in their capabilities.Ĭurrent chips can monitor fan speeds, voltages and control fan speeds by using PWMs (Pulse Width Modulation). Several sensors, like Winbond's and the AS99127F support fan speed changing, as well as others from Maxim, Myson, Analog Devices, National Semiconductor and ITE, but the hardware manufacturer must have connected the relevant pins to some additional, yet trivial, circuitry. SpeedFan can change the FSB on some hardware (but this should be considered a bonus feature). By properly configuring SpeedFan, you can let it change fan speeds based on system temperatures. SpeedFan monitor temperatures from several sources. SpeedFan works with Windows 9x, ME, NT, 2000, 2003, XP, Vista, Windows 7, 2008, Windows 8, Windows 10, Windows 11 and Windows Server 2012. ![]() ![]() What operating systems are compatible with SpeedFan? It includes customizable skins that you can use to build a unique monitoring environment. SpeedFan can also read S.M.A.R.T information from your hard drives, show CPU usage, chipset information, core temperatures, change clock speed, and analyze voltages. Rainmeter Top CPU temperature monitor for Windows devices that monitors core temperatures, CPU, disk usage, and RAM. What other features does SpeedFan offer besides controlling fan speed? Once installed, SpeedFan will automatically detect if your hardware is compatible and advanced features are presented. SpeedFan is able to control the fan speed of most fan makes and models, but this will ultimately depend on your motherboard's sensor chip and capabilities. Can SpeedFan control the fan speed of any fan? "Motherboard" temperature may instead actually be a sensor for Voltage Regulator (VRM) temperature, which for a stock 8700, should be lower than any "Core" temperatures.SpeedFan is a hardware monitor software that can access temperature sensors, but its main feature is that 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. Standard or normal is 22☌ or 72☏.Īdditionally, there is no "Motherboard" sensor for Intel Core i 2nd thru 8th Generation processors with respect to temperature. Core temperatures increase and decrease with ambient temperature. ![]() ![]() Remember to factor in ambient (room) temperature. Between the two utilities, I would always trust HWiNFO first.įor a simple and very straight forward monitoring utility, "Core Temp" is highly recommended - Ĭore Temp will give you the most critical temperature information, which of course is "Core" temperature. Don't be surprised if the values and labels in HWiNFO do not agree with those in HWMonitor. The most accurate and detailed monitoring utility is HWiNFO - ĭownload HWiNFO "Portable" and run "Sensors Only" to cross-check the information you see in HWMonitor for accuracy. Moreover, "CPU" temperature may correspond to "Package" temperature, which is the hottest "Core". See Section 4 Paragraph 3, and Section 13 Note 1 for explanations concerning the temperature fluctuations you're seeing in HWMonitor.Īt 100% workload, it is normal and expected for Core temperatures to be higher than any other temperatures, and it is also normal and expected for Core temperatures to fluctuate widely and rapidly under lower workloads, especially at idle. It's a Sticky near the top of the CPU's Forum. The same goes for HWiNFO which I tend to like a bit more since it doesn't require installation and it's constantly being updated. Tom's has a Guide for this: Intel Temperature Guide - It uses the info from MSI Afterburner which has GPU temps, GPU usage, GPU core/memory clocks, GPU memory usage, CPU usage, CPU temps, etc. ![]()
