HP Elitebook 840 G5 840G5 ZBook 14U G5 Cooling Fan

It looks like you’re asking about the cooling fan for the HP EliteBook 840 G5 and HP ZBook 14u G5, which are both part of HP’s business laptop line. Both models are designed with performance and durability in mind, so cooling is essential to maintain stable operation.

Here’s a bit of useful information regarding the cooling fans for these models:

1. HP EliteBook 840 G5

• The HP EliteBook 840 G5 typically uses a single cooling fan. This fan is designed to keep the processor and other internal components cool during extended usage, especially when running demanding applications.
• If you are experiencing issues with overheating or noisy fans, the fan or thermal system might be clogged with dust, or the thermal paste on the CPU might need replacement.
• Replacement: If the fan fails, it can often be replaced fairly easily, and parts can be found from HP or third-party suppliers. Ensure you get the correct part number to match your specific configuration.

2. HP ZBook 14u G5

• The ZBook 14u G5 is a more powerful workstation laptop with two fans in its thermal design, as it’s meant to handle more intensive tasks like CAD, 3D rendering, or software development.
• If you notice excessive heat or loud fan noise, it could be due to clogged air vents, thermal paste degradation, or the fans needing maintenance or replacement.
• The ZBook series generally has more advanced cooling to support higher-performance processors and GPUs, so make sure to check the condition of both fans.

Fan Replacement & Maintenance:

• Fan cleaning: For both laptops, you can blow out dust from the cooling vents using compressed air, which can often resolve overheating issues. Be sure to blow air through the vents from the exhaust side to avoid pushing dust further inside.
• Thermal Paste: If the laptop is old or has been subjected to heavy use, consider reapplying thermal paste to the CPU or GPU. This can improve heat transfer and help maintain lower temperatures.
• Fan Replacement: If the fan is defective, you can find replacement parts online by searching for the specific model (e.g., “HP EliteBook 840 G5 cooling fan” or “HP ZBook 14u G5 fan”). HP parts suppliers or third-party vendors like eBay, Amazon, and other computer hardware sites typically stock these parts.

Troubleshooting:

• Loud or constant fan noise: Check for dust buildup, as this is a common cause of noisy fans.
• Overheating: If the laptop gets hot or shuts down unexpectedly, it’s worth looking into the fan system or even the overall thermal management design.
