If performed actively, replacing the processor fan on an HP desktop PC 500 Series can be a simple procedure. Maintaining optimal performance and keeping your CPU cool require a functional processor fan.
This tutorial can assist you with replacing your fan if it is noisy, not spinning, or has failed.
Here are the some points which explain more about it:
- Power Down and Unplug: Turn off the PC and disconnect the power cord.
- Open the Case: Remove the side panel (refer to HP manual for specific screws or clips).
- Locate the Processor Fan: Find the fan on the CPU heat sink (part number: HP 639078-001 for the processor fan assembly)
- Disconnect the Fan: Unplug the fan’s connector from the motherboard (usually a 4-pin connector).
- Remove the Old Fan: Unscrew or unclip the fan (part number: HP 739866-001 for replacement fan, if applicable).
- Install the New Fan: Position and secure the new fan with screws or clips, then reconnect the power cable.
- Reassemble the Case: Reattach the side panel and secure it.
- Power On and Test: Plug in the PC, turn it on, and verify the new fan is operating properly.
Readiness and Safety Procedures
- Turn Off and Unplug Your Computer
Turn off your desktop computer completely and disconnect it from all power sources before proceeding. Take off the keyboard, mouse, and external drives from the PC’s back panel and unplug the power cord.
- Collect Required Equipment
You usually need a Phillips head screwdriver to remove screws. Anti-static wrist strap: To shield delicate components from damage caused by static electricity.
Make sure the new CPU fan is compatible with your HP Desktop PC 500 Series before replacing it.
Cracking open the computer case
- Take Out the Side Panel
A side panel on the majority of HP desktop computers must be removed. In accordance with your model, you may need to:
Unscrew: Find the screws keeping the side panel in place, then unscrew them. Usually, you may find these at the case’s back.
Release Clips: In certain circumstances, the panel is released by sliding or pressing clips or latches.
Slide or remove the side panel off with caution, then place it aside.
Tracking Down and Recognizing the Processor Fan
- Locate the Heat Sink and Fan
The CPU heat sink, a metal block intended to dissipate heat, is typically directly connected to the processor fan. A power connector for the fan needs to be connected to the motherboard.
Removing the old processor fan
- Cut the Fan Off
Find the power connector for the fan, which is plugged into the motherboard. Pull it out by gently pressing the tab or clip on the connector.
- Take out the Heat Sink’s Fan
Typically, you use clips or screws to secure the fan.
Unscrew: If the fan is fastened with screws, take out the screws using a screwdriver.
Unclip: Carefully remove the fan from the heat sink if it has clips.
Setting Up the New CPU Fan
- Assign the New Supporter
Put the new fan in the same spot as the old one atop the CPU heat sink. Ensure you position the mounting holes correctly.
- Keep the Fan Secure
Screw: After aligning the new fan with the holes, tighten the screws evenly.
Clip: If the fan has clips, set them in place and press firmly to secure
- Turn on the Fan
Connect the motherboard’s power connector to the fan. Ensure you position it correctly and secure the connection.
Reassembling the Computer Case
- Insert the Side Panel
Back into the Case by sliding or positioning it. Depending on the design of your case, either re-engage the clips or fasten it with screws.
- Connect External Equipment Again
Reconnect any disconnected peripheral devices and plug the PC’s power cord back in.
Checks and finalizations
- Strength Within the PC
As soon as your computer turns on, listen for the new fan to work. It need to rotate silently and smoothly. Look for any strange vibrations or noises.
- Keep an eye on the system temperature
Check CPU temperatures with system monitoring software to make sure the fan is successfully cooling the processor. You can access temperature sensors integrated into most contemporary PCs via the BIOS or external applications.
- Look for Any Blockages
Align the fan with the heat sink correctly and check that nothing obstructs its movement.
