How to Install the Additional Fans for Computers

Additional fans are used in computers for cooling components. All coolers are installed inside the computer and connect to the appropriate power connector on the motherboard. Suitable slot should be selected according to the type of the radiator and its location.

Disconnect power from the computer and open the cover by removing the rear panel of the device screws with a screwdriver. On some computers, the side wall is held on special mounts that should weaken to gain access to the 120mm fan cover. After removing the side wall, specify the location of the cooler installation. It should be determined depending on the role of the fan installed. If you plan to install the fan blow-out, they should fix for the rear wall. To ensure the body cool air fan is set on the front panel by removing interfering parts with a screwdriver.

If you are installing the cooler on the processor, carefully review the method of fastening of a radiator. Relax fan clips and loosen its screws with a screwdriver. Remove the heat sink and note the port that is the power wiring that connects to the motherboard. Also look at the amount of thermal paste on the CPU. If the paste has dried, apply another thin layer of the composition on the stone. BTW, you can select the additional fans at Banggood. Besides, you can easily get other computer accessories (e.g. USB adapter set) there with high quality and reasonable prices.

Carefully remove the old and install the new cooler, and then secure it with screws. Connect the power wiring to the motherboard. By installing the cooler, note the presence of connectors for connecting additional cooling to the motherboard. Slots fan headers are designated as SYS_FAN with the corresponding markings on the motherboard.

After product installation fasten fans with screws. Connect the computer to the power supply and turn it on by pressing the corresponding button on the body. If the connection was made correctly, the fans will start to spin. Attach the side cover. Installation of fans in the computer case is completed.

How to Lubricate Acer Laptop Cooler

High-quality cooling system mobile computer ensures stable operation of important elements of the notebook. Timely service allows fans to extend the life of these devices.

You will need

- Silicone Grease;

- Crosshead screwdriver;

- Cotton pads;

- A metal blade;

- Tweezers.

Find out what kind of cooler is not working properly. To do this, set the Everest program, start it and open the menu "Sensor." Find the equipment whose temperature is higher than normal. Turn off the mobile computer. Disconnect the device from the AC mains. Turn the laptop case and remove the battery. Now unscrew the necessary screws of the mobile computer case. Remove some devices that interfere with normal body disassembly. More often than not to open the case you need to remove the hard drive, memory modules and the DVD-ROM drive. Carefully separate the part of the body apart. It is better to use a metal spatula. If you do not have such a tool, use a screwdriver with a flat tip.

Lift one side of the body and disconnect several cables. This process must be carried out with tweezers or small pliers. Remove the lower part of the body and find the fan. Unplug the power cable for this device. Unscrew a few screws and remove the cooler (e.g. Acer Aspire 5100 fan). Remove the plastic plug. Use tweezers or a needle pull locking gasket and rubber ring. After that, remove the blade from the axle.

Clean the shaft and fan blade with a cotton pad. Apply a small amount of grease to the axis of rotation. Install the blades and scroll through them a few times to distribute the lubricant. Replace the retaining ring and gasket. Put on the cover and attach the cooler to the radiator. Assemble the mobile computer in reverse order. Turn on the laptop and after 20-30 minutes, run the Everest program. Check the temperature of the relevant elements. BTW, you can select the replacement of Acer Aspire 5100 CPU fan at Banggood. Besides, you can easily get other computer accessories there with high quality and reasonable prices.

How to Install PCI E Graphics Card

To date, almost all motherboards graphics cards used to connect PCI Express slot, which in comparison with its predecessor AGP (accelerated graphics port) has a higher capacity. Therefore, modern graphics cards and are connected to the PCI Express connector.

You will need

- a computer;

- Screwdriver.

First, you need to prepare your computer. To do this, disconnect all peripherals. Then unplug the system unit from the power supply and remove the cover. Basically, it is fastened with screws, or special clips. Then you need to put the system unit so as to obtain easy access to the system board.

Next, locate the PCI Express connector. If you have a diagram of the motherboard, the first to do is finding this connector on it. Typically, PCI Express is located in the lower left part of the board. Each of the connectors is signed so that it is impossible to mix. Note that on some laptop mini PCIE graphics cards may be several PCI Express connectors. In such a motherboard can be, respectively, to set multiple graphics adapters.

Video connection procedure itself is quite simple. Dock connector to connect the board to the PCI Express-connector. Then gently push the graphics adapter. The device must enter very easily. Now it remains only to fix the card to the system case. This is done using a conventional fixing screw. Many graphics card PCI Express standard require additional power. To find out whether your board is required per se, it is possible to guide it. Connector power supply to the unit is at its end. Plug this connector 6 Pin Connector of the power supply. Some video card is powered via 8 Pin Connector. This procedure is completed to connect the PCIE ESATA adapter card.

Close the system cover. Connect all peripheral devices. Turn on the computer immediately after the launch of the system will be notified about the new device. After that you need to be sure to install the driver for your video card.

How to Build a 5 Volt DC Source

For electronics enthusiasts the presence of 5 V DC can be very useful. Many microcontrollers and digital integrated board accept 5V voltage (generally, this number ranges from 3 to 15).This guide to create a 5V DC power supply, which can create a current of up to 1.5A power. You will need to combine several components.

One of the wires of the AC adapter will be considered positive. The other is a ground wire. At the moment, it does not matter which of the wires you select for a role, it is only important to remember your choice. Connect the positive lead from the AC adapter to the diode side, not the marked line. You connect the positive lead to the anode of the diode where the current will flow through the diode in one direction only and charge the capacitor which you connect later.

Locate the capacitor lead marked line. Typically, a line of white color is drawn minus sign. This is the negative side. You have to connect the DC 5V cable to the AC adapter. Connect the other wire to the capacitor diode marked line. Thus, we connect the positive lead of the capacitor to the cathode of the diode. The diode allows current from the transformer to charge the capacitor and thus prevents the capacitor is discharged through a transformer.

Connect pin 1 of the voltage regulator with a branch point where the positive side of the capacitor is connected to the marked side of the diode line. Pin 2 should be connected to a ground wire from the AC adapter. Track 3 - it is a way out. Between the terminal 3 and the ground voltage will be 5V. BTW, you can select the 5V DC power supply at Banggood. Besides, you can easily get other computer accessories (e.g. 3.5mm 90 degree adapter) there with high quality and reasonable prices.
