HP Elitebook 840 G5 G6 ZBook 14U G5 Laptop Cpu Cooling Fan Orginal

Description

If you’re looking for a replacement or upgrade CPU cooling fan for an HP EliteBook 840 G5, HP EliteBook 840 G6, or HP ZBook 14U G5, here are some steps and important information to help guide you:

1. Confirm Compatibility:

• HP EliteBook 840 G5 and G6: These models are part of HP’s business-focused lineup and are often powered by Intel Core i5 or i7 processors, typically in an ultrabook form factor. The G5 and G6 have similar cooling systems, but make sure to confirm the exact model of your laptop before purchasing a fan.
• HP ZBook 14U G5: This is a mobile workstation model, also with Intel Core processors, but it may have a slightly different cooling setup due to its more powerful GPU options.

Key to ensuring compatibility: You should always double-check the part number or model specifics to avoid buying the wrong part.

2. Identifying the Correct Cooling Fan:

Each of these models has specific cooling fan parts designed for the thermal needs of the respective processor and chassis size.

• Part Number for Cooling Fans: HP parts for these devices typically have specific part numbers. Some common cooling fan part numbers for these models include:
  • HP EliteBook 840 G5: Part numbers like L31997-001, L31868-001, or similar.
  • HP EliteBook 840 G6: Similar part numbers such as L31999-001 or L31896-001.
  • HP ZBook 14U G5: You may find part numbers like L31994-001 or L31865-001.

To get the exact part, check your laptop’s service manual or the existing fan for its part number.

3. Where to Buy:

• HP Parts Store: You can purchase original replacement fans directly from HP or from authorized resellers.
• Online Marketplaces: Sites like eBay, Amazon, or Newegg also offer cooling fans for laptops, but ensure that the seller provides the correct part number.
• Third-party Suppliers: Some companies specialize in replacement laptop components, such as LaptopPartsExpert, Parts-People, or CompuTronix.

4. Replacing the Cooling Fan:

If you’re planning to replace the cooling fan yourself, follow these general steps:

• Turn off the laptop and unplug it from any power source.
• Remove the back panel by unscrewing the screws (you may need a small screwdriver like a Phillips head or Torx screwdrivers).
• Disconnect the battery (if applicable) to avoid short-circuiting.
• Locate the cooling fan: The fan is usually situated near the CPU, typically covered by a metal shield or bracket.
• Remove the fan: Disconnect the fan’s power cable from the motherboard and unscrew any screws holding the fan in place.
• Install the new fan: Place the new fan into the same position, reconnect the power cable, and screw it back into place.
• Reassemble the laptop, reconnect the battery, and test the fan by turning on the laptop.

5. Thermal Paste and Maintenance:

While replacing the fan, it’s a good idea to reapply thermal paste to the CPU and possibly the GPU (if applicable), as thermal paste can degrade over time. This ensures better heat transfer from the processor to the heat sink and fan.

6. Possible Signs of Fan Issues:

• Overheating: If your laptop is getting very hot or shutting down due to heat, the fan may be failing or clogged.
• Noise: A loud or rattling fan can indicate dust buildup, a loose fan, or bearing wear.
• Slow Performance: Inconsistent fan operation can cause thermal throttling, leading to reduced performance.

If you have any doubts about performing the replacement yourself, or if you’re not sure about the part compatibility, consider consulting a technician or visiting an authorized service center.
