BUY TOSHIBA SATELLITE C850 COOLING FAN REPLACEMENT FOR SALE IN NAIROBI CBD KENYA

The cooling fan in the Toshiba Satellite C850 is a critical component that helps prevent the laptop from overheating by dissipating the heat generated by the CPU, GPU, and other internal components. Here’s a detailed look at it:

Toshiba Satellite C850 Cooling Fan – Overview

• Function:

  • The cooling fan blows air through the heat sink to keep the internal temperature of the laptop at safe levels.

  • Prevents thermal throttling (slowdown of components due to heat) and protects the CPU and GPU from damage caused by overheating.

Key Features:

• Type: Typically a DC brushless fan powered by the motherboard

• Location: Usually located under the bottom base, near the CPU and GPU heat pipes.

  • May have a fan shroud or vent cover over it.

• Airflow Direction: The fan pulls air in from the bottom of the laptop and exhausts it through vents, usually located on the side or back.

• Speed Control: The fan speed is controlled by the laptop’s BIOS and adjusts depending on the temperature of the internal components.

Common Cooling Fan Issues:

1. Noisy Fan:

   • This could be due to dust buildup inside the fan blades or a failing fan motor.

   • Can also indicate worn-out bearings.

2. Overheating:

   • If the fan is not working properly, the laptop can overheat, leading to thermal shutdowns or slow performance.

3. Fan Not Spinning:

   • This could be due to a faulty connection, dust blockage, or a defective fan motor.

   • Check for dust buildup on the fan blades and vents.

4. Fan Running Constantly:

   • If the fan runs at full speed all the time, it could mean that the thermal paste between the CPU/GPU and the heat sink has dried out or become ineffective.

Fan Replacement Steps:

1. Power Off and Unplug the Laptop:

   • Remove the battery if possible for safety.

2. Disassemble the Laptop:

   • Remove the bottom cover, usually by unscrewing screws that hold it in place. The fan is often accessible under this.

3. Locate the Fan:

   • The fan will be next to the heat sink, attached to the motherboard.

4. Disconnect the Fan:

   • Unplug the fan cable from the motherboard (this will usually have a small 3- or 4-pin connector).

   • Remove any screws securing the fan to the chassis.

5. Install the New Fan:

   • Place the new fan into the same position and secure it with screws.

   • Reconnect the fan cable to the motherboard.

6. Reassemble the Laptop:

   • Put the bottom cover back on and screw it in place.

7. Test the Fan:

   • Power on the laptop and check the fan’s operation through system utilities or by observing if it’s running silently and smoothly.
