- Speed Fan.
First check the settings of the fans, using the firmware of the motherboard. Turn on the computer. After the first boot menu, press Delete, and wait for the BIOS menu.
Navigate to Advanced Chipset. It is important to note that in certain models the menu may have a different name. Find the item displays the settings of the fans installed in the system unit. Remember that not all coolers are subject to adjustment. Some models are always rotating with certain constant speed.
Make sure that the function is Always active Fan. If firmware allow you to set a specific speed for the fan, select 100%. Set this value for each available cooler.
Repeatedly press the Esc key to return to main BIOS menu. Use the arrows to highlight Save & Exit Setup and press Enter. Press the Ok button. Wait until the operating system loads.
In situations where the functionality of the firmware is severely limited, use the Speed Fan. Install this program and run it. Wait some time until you will be presented with information on the status of available fans.
Deactivate the automatic change of speed of rotation of the cooler. Install score of 100% for each device. When dealing with mobile computer wiser not to activate maximum speed. This will prolong the life of the laptop without connecting the power supply.
If you want the program to automatically regulate the operation of the coolers activate "Autoscroll fans". Note that after you close the app Speed the Fan speed of the coolers will come to the original value.
Advice 2 : How to reduce the noise from the coolers
The noise from the coolers in addition to discomfort, can bring more serious problems. In particular, this may indicate that the CPU is overheating or just the cooler is too weak (unable to cool the components as it should), in this case, of course, should take serious measures.
The most common cause of noise of the cooler is overheating of the processor. If long time not to apply CPU thermal grease. Usually thermal paste is applied about once a year, is not critical, however, and every two years. But if you long this is not done, the processor will overheat, and a cooler of hard work. This situation, among other things, can create discomfort to work in the operating system, i.e. sometimes the application may slow down, fail, etc.
Sometimes the noise may cause a cooler, despite the fact that the processor is not much too hot. The fact that most cheap computers (e.g., office/budget models) usually mounted dispensers are of poor quality. This situation, if it is critical (often the cooler runs very loud) can only be changed by replacement of the cooler. In order to get rid of the noise, you need to buy coolers of good firms (e.g., firms Zalman).
The rpm fan speed can be controlled, for example, using the program Everest. You can choose either optimal, or to monitor the rotation speed and to leave the desired rpm. Interestingly, the program notes the critical point.
It happens that the cause of the noise may not be the CPU and the cooler in the power unit. The reason for this lies again in the weak configuration of the computer. In the budget "Assembly" of the computer most often include bad power supplies. For slower computers the optimum power supply is 400W. If less, it is possible that he just can't cope with the load, and, alas, it is possible to correct only the change of the power supply.
With the replacement of components this problem can be solved naturally, reducing the noise to a minimum. You need to put the cooler company Zalman (or any other good company). Preferably, besides a good CPU cooler, the PSU, even put a cooler on the back wall of the computer, in order to provide additional cooling for the hard drive, graphics card. Because sometimes they, too, are cause of noise.
