When the computer is working, the video card coolers shouldspinning is their normal mode of operation. But often some users are faced with a problem when the cooler on the video card does not spin. It is not necessary to panic, because in some cases even this situation is normal. But it is still recommended to understand.
Some models of video cards are equipped with coolers,which revolve constantly. This is considered normal operation, but other models are cooled only when the graphics processor is warmed up. In such graphics cards, the cooler does not rotate at a chip heating temperature of up to 50 degrees, but the exact figure depends on the model itself. Some video cards have a higher temperature limit for the activation of coolers. Modern chips with large heat sinks can heat up to 70 degrees and even more. The fans will not rotate, and only when they reach a certain temperature (for example, up to 75 degrees) they are activated. However, after the temperature falls below the set threshold, the cooler on the video card stops spinning.
Сделано это для сохранения ресурса вентиляторов и saving power, which is quite logical, because there is no need to rotate the coolers for nothing, if the chip does well without them. But in many models this system is absent, and coolers start to spin already when you press the power button of the computer.
Поэтому для начала нужно попробовать просто run any game on the computer. The graphics processor will be loaded. As a result, it will heat up, and a special algorithm will start the coolers. If the fans spun after heating the chip, then it means that they are all right.
Despite the fact that the fans can not rotatefor a natural reason, possible failures are not excluded. In the event that the cooler on the video card does not rotate, when the GPU temperature rises above 50 or 75 degrees (as specified by the system), then this is a cause for concern. This may occur due to a breakdown in the hardware or software part of the video card.
Most often with an increase in temperature to 51degree algorithm should run the coolers, and if it did not, then first you need to try changing the drivers. The fact is that the instructions for starting and stopping coolers are stored in the driver, and often after removing the old ones and installing new drivers, the video card starts working stably, like its cooling system, including the fans.
If even after changing the driver the problem remains,then you need to dig deeper. First you should try to start them manually. This is done using a special application that is installed with the driver. Depending on the manufacturer and model of the map, the application can be called differently. Most often, together with the driver for the AMD card, the AMD Control Center program is installed.
In this program, you can manually set the speedrotate the fans and start them. If the fans rotate, this indicates a malfunction of the temperature sensor. It does not work, which means that the system thinks that the temperature is always normal. Consequently, the algorithm will not apply voltage to the fans. You can live with this breakdown, but it's not entirely convenient. After all, when running games, you have to manually activate the fans to maximum, to ensure good cooling.
But even if they do not rotate after the manual start, then, most likely, the problem is not in the software part, but in the hardware part.
Very rarely due to lack of power supply cooleron the video card does not rotate. What to do in this case? At a minimum, you can try to install a more powerful power supply, after which the fans will start again. But quite often this problem happens due to lack of nutrition. Most likely, there is a hardware (physical) failure.
One more variant of the decision, which is unlikelywill help (but there is hope): you remove the video card, wipe the contacts with alcohol, connect it back. If the coolers spin, it means that some of the contacts were oxidized, because of which the current did not flow to the fans, and they did not rotate.
In this case, the card must be removed andservice center. If it has a warranty, then repair costs are free. Otherwise, you have to pay. Such a breakdown is quite common, and repairing it is simple. Most likely, the problem lies in the fact that the coolers do not receive current, which indicates the breakdown of any track on the graphics card.
The last case, when there is no image, the coolerThe video card is spinning and nothing happens on the screen at all. In this case, the problem is not in the fans, but in the failure of the video card. Full diagnostics and repairs are needed here. Independently determine the cause does not work, if only you have a multimeter and you are well versed in electronic circuits.
