Explosion proof for computers on summer days

Most common computer users "forget" the temperature factor when shopping or operating but only pay attention to the parameters of speed, clock speed, capacity and price. Meanwhile, failures such as circuit burns and chip blasts are often denied by the supplier.

Temperature in computer

When computers work, electricity flows through transistors and circuits that generate heat. A chip can be hotter than the ambient temperature around it (in the case) 10-15 degrees Celsius. This temperature is directly proportional to the pulse of the chip and the operating voltage.

In product design, computer component manufacturers also have to set aside an amount to solve the heat generated in their products under normal working conditions. Chips take on heavy jobs like CPUs, graphics processing (GPUs) often have their own heat sink and blower.

The main IC of the mainboard, high-speed RAM is also equipped with aluminum heat sink. The "thirsty" computer of speed like gamers, mod case must have its own heat dissipation device depending on the level of increase in core voltage and clock speed of the chip.

The heat resistance of computer components varies depending on the type of product, manufacturer, popular working temperature range from 0 to 70 degrees C. According to the manufacturer's recommendations, the ideal environment for computers to do work from 15 - 24 degrees C.

Most computers in Vietnam do not have such "cold room" environment in addition to the number of facilities at offices and offices. In the game shops, households, the temperature outside the case is about 30 degrees Celsius. At that time, inside the cabinet is about 35-40 degrees Celsius due to the heat from the internal parts, the radiator fan is also just blowing around in the barrel. The temperature of the normal operating chip was approximately 60 degrees Celsius.

On hot, continuous days, unexposed heat will make the circuit, the delicate link inside the IC temporarily deformed, the computer works incorrectly or slowly. Maintaining that condition for a long time can cause IC explosion, destroy components. Some new generation motherboards and chips have the ability to protect themselves and give warnings when reaching certain thresholds. If the temperature does not decrease the machine will stop working.

Explosion not only because of heat dissipation

" There are many reasons for components explosion, possibly due to unstable power supply voltage, poor quality components or assembly errors when the assembly makes contact heatsink not good, " a security technician TIC company (Hanoi) said. " Computers in Vietnam are mainly manual assembly, sometimes users buy hard drives, RAM, video cards . to upgrade. Sometimes a bad component is the cause of the failure. of another ".

Most manufacturers refuse warranty for explosion-proof products that only support for repair. The reason they give is that the pre-sale products are for a certain period of time. The explosion is mainly due to the way the user operates and uses it. However, there are still a few retail companies that take risks, commit themselves to warranty for their customers.

In fact, components can withstand temperatures higher than the manufacturer's number indicated on the product packaging. However, many other factors such as dust and dirt reduce the amount of air circulation, exposure is not good, . make the heat dissipation ability decrease, the working temperature can increase abnormally. On the other hand, dust and dirt when exposed to humid air can cause short circuits at IC pins, burning components.

Lower "fever" for the computer

A good source is an important factor in limiting fire and explosion of computer components. In addition to being large enough to power the entire computer, power quality is also in place to ensure the stability of the current.

The new Minboard has all reserved an item in the ROM-BIOS to set up temperature management. Depending on the model and manufacturer, the number of sensors "installed" on different mainboard. The universal product type allows users to know the number of chip fans, VGA fans and chip temperatures. More expensive types allow users to set a thermal scheme to detail to alert and turn off the computer when it is too hot. The chip temperature usually defaults to 60 degrees Celsius and stops working at 65 degrees Celsius. Speakers on the main will constantly emit a fire-like sound when reaching the threshold.

At the same price, chips manufactured by AMD have higher performance but are also hotter than Intel chips when operating. Gaming enthusiasts and technical graphics prefer AMD, but also have to spend more money on the radiator.

Computers at the game store or the public Internet often get a lot of dust because they are located on the road surface, not carefully covered like personal computers at home or at work. They need to be cleaned once a week to ensure no unexpected problems.

Home users can control their computer temperature via the Setup section of the BIOS ROM and utilities included with the motherboard. If it's just horizontal, you can download the hardware test utility like Everest from Lavalys to monitor the thermal sensor on the motherboard. The chip temperature maintained below 55 degrees Celsius is the best condition. If the temperature rises quickly after a short period of operation, it is a sign that the cooling system needs to be upgraded.
