Errors and Troubleshooting on Computer Cooling System


Computer Cooling System.

One of the problems with computers is that almost all components in the CPU (processor, motherboard, VGA, hard drive, and others) generate heat. Relatively high temperatures will result in shortening the life of computer peripherals, even making the system unstable. Manufacturers minimize heat by reducing the size of semiconductor cores for processors, chipsets, and other peripherals. In fact, currently, a processor already has a TDP (Thermal Design Power or Thermal Design Point) feature on the INTEL processor and Cool'n Quite on the AMD processor to overcome the heat generated.

  • Dust that sticks to every peripheral and cooling component.
  • Wind turbulence in the computer case is not optimal so that heat is collected in one place.
  • sub-optimal heat spreader or cooling heat sink.
In general, computer users use the standard Peripheral cooling system. The standard cooling system is relatively sufficient for standard computer use as well. As for a PC that works 24 hours per day or an overclock that forces the PC to its limit, surely a standard cooling system will not be enough to release the heat generated by computer peripherals.

Air conditioning systems utilize the movement of air exhaled by fans or fans towards the periphery with or without additional heatsinks (cooling fins). This system is the oldest refrigeration system which is the refrigeration standard and is relatively inexpensive. The fin-shaped heatsink absorbs and dissipates heat, while the fan accelerates the decomposition of the heatsink into the air.

Some of the disadvantages of air conditioning systems are:

  • At a high fan, the rotation will produce a fairly annoying sound. The sound can come from fan vibration or wind turbulence.
  • There is a buildup of dust, especially in areas that are passed by a fairly strong wind flow. even more dangerous if the dust contains metal elements.

Currently, copper is widely used as a heat absorber in collaboration with aluminum as a heat dissipator and heat pipes to flow and large diameter fans to reduce noise. The shape and basic materials of heatsinks vary, there are full copper, nickel-plated copper, a combination of copper and aluminum.

The heatsink is divided into two parts, namely the heat-absorbing part and the cooling part, the heat-absorbing part is usually made of aluminum or copper. Heatsinks can be fanless (passive cooling) or fan (active cooling).

The quality of a heatsink is determined by several factors:

  • HSA (Heatsink Surface Area) / heatsink surface area which will result in better heat dissipation.2.A good aerodynamic shape can facilitate the flow of hot air so that it is quickly removed through the cooling fins.
  • Good heat transfer on each heatsink will also facilitate the release of heat from the heat source to the cooling fins.
  • A smooth base surface can absorb heat more perfectly, but to be safe, you still have to use thermal paste so that the touch surface area is also more evenly distributed.

The performance of a cooling system is rated in °C/W (or K/W) C here is Celsius and K is Kelvin. For example, if a peripheral is powered by 20 W, and the temperature increase is 10°C, then the cooling rate of the system is 10°C/20 W or 0.5°C/W.

Errors and Troubleshooting on Computer Cooling System

Dirty fan and heatsink

The fan/tire is jammed because the cable/lubricant in the fan bed is dry. The solution: Remove the rubber and bearing cover sticker on the back of the fan.

Apply oil/oil to the fan/fan bearings while the fan blade is rotated slowly so that the oil/oil is absorbed, when finished cover it again with rubber and a sticker.

Dirty fan and heatsink

This can cause the computer to shut down suddenly because the bios on the motherboard detect an excess temperature so that it runs the command temperature protection.

The solution: Clean the old paste on the heatsink and processor. Clean the old paste that has dried on the processor and heatsink, then put a new paste on the processor. Replace the heat sink on the processor.

Summary

Search and solve on video and soundcards as well as storage media, power supply, and cooling systems on computers. It is an activity to identify and analyze a malfunction in these components. The procedure in this learning activity is a general procedure that can be applied in overcoming a problem in the computer.
