System Monitoring Processor and System Temperature Software
A computer is a complex machine which asks for a minimum maintenance. A fan which for some reason rotate at lower rate, a heating up processor, hard disk boiling with risk of data losses are common for today computer. To avoid such problem, user has to monitor its computer temperature : using software which give access to multiple information giving notice before possible problem.

Many manufacturers, motherboard or graphics card in particular, has interest in such devices, and several of them systematically join their products with programs dedicated to component monitoring . The question here what user has to monitor ? How information comes to us ? Which application software to use?……
Monitoring, why and how?
First , what is monitoring? we could define it as the evaluation values which move in the course of time and which characterizes certain computer components operation .
Here is an example of fan able to tell about its current rotation rate.

This type of connector transmits to the motherboard the number of its RPM (rotation per minutes)
Most fan and motherboard come with similar connector . Recent graphics card have also a mechanism allowing to record the chips temperature , just like the processors for several years.
Many software help in the monitoring task, including Windows tools . For example Windows tasks manager , show the current processor load , then you can see if some program is eating a lot of resource .

Motherboards manufacturers solutions
Asus
- The temperatures reach higher value than the limits defined ;
- Fan rotation speed lower than the value limits defined ;
- Important variation (expressed in percentage) over the default voltage value (can be controlled in the program setting ).
AI Suite takes again the data of Asus Probe II, adding the processor frequency , FSB and the distributed load between core (in can of multi core processor). Note that if Asus Probe is a small application intended only for monitoring, AI Suite is more advanced application with overclocking capability.

Gigabyte propose another software called Easy Vtune 5, it is necessary for us to move directly to PC Health section located in bottom , in order to avoid many overclocking options and to reach the place witch interests us (Hardware Monitor). Here, you will be able to find the voltage values , the fan speed as well as the processor (and more precisely that external temperatures sensor) and the motherboard temperatures . There is a possibility to control critical points for these parameters above which an alarm will start (using any custom made sound file * .wav or * .mid).

- for the graphics card, the GPU, memory clock frequency , the fan speed , the supplied voltage and the card temperature ;
- for the motherboard we have : the supply voltages, the processor frequency , its temperature and fan speed. Note it is possible (just like Speedfan) to control the fan speed and setting can be saved after restart .

Gigabyte and its V-Tuner 3 allow certainly to overclock the graphics card but also show the temperature sensor results . The value given can be shown in degree Celsius or Fahrenheit and a small graph informs users about the variation of this value in the course of time (useful to know how temperature rise after launching a game for example).

A known and recognized software: Speedfan
Presentation
The famous software Speedfan, which is developed by Alfredo Milani-Comparetti (who began his work in 2000), is a software with the multiple functionalities:
- reading temperature sensors from many motherboards and processors;
- analyze (via system S. M. A.R.T.) the health of your hard disks and recovery temperatures ;
- possibility, with compatible motherboards to read fan speeds and adjust their rotation according to established criteria .
- read processor voltages
- possibility to start an action when a condition is reached (for example if the processor temperature exceeds 50°C, it play an alarming sound );
- for compatible processors (unfortunately few), it adjust the FSB according to the processor load .
Moreover it is compatible with Vista, including the 64 bits version. The correct operation of Speedfan strongly depends on your current hardware. However, the frequent updates make this program compatible with many motherboard models and about all current processors .
Installation
You can download the last Speedfan version here . The current version is SpeedFan 4.32 and can be directly downloaded from our site. After a quick install process u will obtain this screen:


Speedfan is available in many languages
- Readings, which is the most important and on which we will return later;
- Clock, which is the software part which allow to adjust FSB for certain processors. Unfortunately, only old platforms (Socket A or 478) are supported
- Info, This window will inform about the nature of your components (motherboard chipset , memory latency …) ;
- S. M. A.R.T., for Self-service Monitoring Analysis & Technology Reporting, this is the information about the health of your hard disks. Very useful to anticipate a possible failure .
- Graphic finally, which allow to build charts from the current value temperature, voltage, fan speed ….
Thus in the Readings tab , you can obtain something like that:
The principal Speedfan window
Configuration
- Select sensor which interest you, after having recognized the most interesting (for example : in the column Label, HDD > for hard disks, Core for processors );
- if you detected the processor sensor and the fan used to cool it (here Processor and “Speed01”), associating them will allow Speedfan to act on the fan speed when the processor temperature increases in order to control it. You can proceed in the same way with fan and hard disk temperature for example.

The tab fan, Voltages are respectively used for selecting fan and voltage which you wish to see in the reading window . Just like the temperatures tab , you can remove the values which are not useful . The tab speeds allow to choose the number of fan rotation which can be adjusted by Speedfan, and in bottom of this window, you will be able to define the limiting values used by the software for the fan speed , in order to control the noise and temperature (attention, certain fan could stop if you set too low rotation speed !).
Once configured, information appears more clearly in the window of reading
events windows with large functionality
- if the temperature of processor exceeds 50°C, the software sends an email to address defined with for object Your processor will burn.
- if the rail 12V is lower than 11,5V, a pop up will post “You draw too much on your 12V!!! ”;
- if the error rate in disc writing System is at value 125 (the base being 100), Speedfan launches Scandisk;
- finally if the processor fan rotation number go down under the 1500 rp/m, Speedfan start a beep.
Other powerful Monitoring software
Motherboard Monitor
Here is some functionalities from MBM :
- Fan speed control;
- Monitor processor or memory voltage ( interesting functionality for overclockers in particular);
- Follow in real time (without Windows manager tasks ) the processors load ;
- Have an eye on the temperature of all computer components : motherboards, processor, hard disks;
- Have a sound or visual alarm programmable in event ;
- Email alert ;
- Start or stop program at defined temperature.
- Personalize monitoring value fonts, colors…

Motherboard Monitor
Programs functioning with MBM
Among those software, We finds in particular Sysmetrix. This small program, in the line of Samurize, can be configured in a very personalized way, and show many information: the processor load , quantity of used memory , traffic inbound and outgoing, as well as the disk space. The temperature sensors are those of Motherboard Monitor, but there is not temperature of S-ATA hard disks or graphics card.Coolmon is also one of the Motherboard Monitor children . Similar to Sysmetrix and even more to Samurize (in particular with its configuration module ), Coolmon is more successful than Sysmetrix, but more difficult to handle. The monitoring possibilities are also large , even if this software does not profit from many Samurize plug-in , which remains the reference. You can get different temperatures kinds (except for the graphics card).

Other temperature monitoring ways
The data brought are complete:
- in the Computer TAB, Overclock, We finds the processor clock frequency , multiplier, FSB ….
- always in Computer tab , but this time in sensors section , where you will find the motherboard temperatures , external processor sensor, (or if available internal : intern (S) ), hard disks temperature ; also fan speeds and various voltage (core, 3,3V, 5V and 12V). In addition if available u will get also the GPU temperature .
- in the tab Motherboard, you can find all information about your Processor and Memory .
- In the part Storage u will find useful information about physical Discs and SMART will bring all indications about the health of your hdd’s;
- finally in the tab Network, Windows Network, you will be able to follow in real time the traffic of your Internet connection , via lines bytes received or bytes sent.
Its direct competitor, Sandra, are available free on its reduced version XI. The principle is the same one as on Everest, and you will be able to find some performance indicators of your PC:
- Click on the icon Motherboard to open access to temperature sensors…. You will be able to also check the voltage values resulting from your power supply rails;
- Click on Processors to estimates the power consumption of your CPU and the capacity of your cooling system , as well as its temperature and voltage.
- if you choose the icon Physical Discs , you will be able to reach the temperature page with SMART data .
- finally for overclockers which would like to test the reliability of their processor, their is module that allow to load the processor to the maximum with simultaneous temperature monitoring..
