Fan (cooler) in a laptop HP - a critical component responsible for cooling the processor and video card. Over time, it becomes clogged with dust, the bearings wear out, or the blades begin to catch wires, which leads to overheating, sudden shutdowns and loss of performance. If your HP Pavilion G6, Omen 15 or ProBook 450 began to make loud noise, and the temperature under load exceeded 90°C — it's time to think about replacing the cooler.

This article will help you figure out how change the cooler yourself on a laptop HPwithout contacting the service center. We will look at choosing a compatible fan, complete disassembly of the case (including complex models with a metal chassis), the nuances of disconnecting cables, and post-installation testing. We will pay special attention models with a soldered cooler (for example, some HP Spectre x360), where replacement requires special equipment.

1. How to understand that the cooler needs replacement: symptoms and diagnostics

Before disassembling the laptop, make sure that the problem is with the fan. Here are the key signs of a problem:

  • 🔊 Constant noise even in idle mode - creaking, crackling or humming of bearings.
  • 🌡️ Overheating: CPU temperature rises to 85–100°C at minimum load (check in HWMonitor or Core Temp).
  • 🖥️ Spontaneous shutdowns or throttling (a sharp drop in CPU frequency).
  • 🌀 Cooler does not spin or rotates jerkily (visible through the ventilation grilles).

For an accurate diagnosis:

  1. Start the laptop and place your hand near the vents. If the air flow is weak or absent, the problem is in the cooler or cooling system.
  2. Use the program SpeedFanto check the fan speed. Normal for most models HP — 2000–4000 RPM under load.
  3. Disassemble the laptop (at least by removing the bottom cover) and visually inspect the cooler. If the blades touch the wires or there is play on the fan axis, replacement is required.
⚠️ Attention: On some models HP (For example, EliteBook 840 G5) the cooler is controlled via EC controller. If the fan does not start even after replacement, you may need to flash the BIOS or reset the EC settings (done through the service menu, accessible via Win+B when loading).
📊 What symptom of a cooler malfunction do you observe?
  • Noise and creaking
  • Overheating and shutdowns
  • Cooler does not spin
  • All of the above

2. Choosing a new cooler: compatibility and where to buy

Choose a laptop cooler HP more difficult than for a stationary PC - not only the fan model is important here, but also motherboard revision. For example, HP Pavilion 15 2018 and 2020 may have different cooler power connectors, despite the same case.

Where to find the exact cooler model:

  • 🔧 Sticker on the fan itself (for example, Delta AFC1212DE or Sunon PF60251VX-Q000U-A99).
  • 📄 B service manual (search by laptop model + "service manual"). For HP such manuals are often posted on official website.
  • 🛒 On the websites of spare parts sellers (for example, AliExpress, eBay, Notebook-Parts.com) by filter "HP + laptop model + cooling fan".
Laptop model HP Cooler type Article (example) Price, ₽
HP Pavilion 15-ec1xxx Single, 70×70×10 mm Sunon PF70251VX-Q000U-A99 1 200–1 800
HP Omen 15-2021 Dual (CPU + GPU), 92 mm Delta AFB0912VH 2 500–3 500
HP ProBook 450 G7 Single, 60×60×15 mm Nidec TA450DC 800–1 500
HP Envy x360 13 Ultra-thin, 50×50×5 mm AVC D501005BH 1 800–2 500

Please note:

  • 🔌 Power connector: y HP There are 2-, 3- and 4-pin connectors. Four-pins support speed control (PWM).
  • 📏 Dimensions: Measure the old cooler with a caliper. Dimensional tolerance - no more ±1 mm.
  • 🔄 Direction of rotation: there should be an arrow on the fan housing → Air Flow. For HP usually used "blow" (blowing air out of the housing).
⚠️ Attention: Don't buy coolers with AliExpress no reviews! Sellers often indicate incorrect compatibility. Check the photo of the connector and compare it with your fan. For example, a cooler from HP Pavilion 15 not suitable for HP 15s-eq2xxx, despite the external similarity.

3. Tools for replacement: what you need

To disassemble a laptop HP and prepare a replacement cooler:

Phillips screwdriver (PH0, PH1) for housing screws|

Plastic spatulas or picks for opening latches|

Tweezers for disconnecting cables|

Thermal paste (eg. Arctic MX-6 or Noctua NT-H2)|

Alcohol and cotton swabs for radiator cleaning|

Antistatic wrist strap (optional but recommended)|

Hairdryer or can of compressed air to remove dust -->

Features of tools for HP:

  • 🔩 Screws in laptops HP often have different lengths. Take photos of their locations before disassembling or use containers for sorting.
  • 🔧 For models with a metal body (for example, HP EliteBook) may be required Torx T5/T6.
  • 🧲 If the cooler is soldered to the radiator (found in HP Spectre or Envy), needed soldering iron and solder.

Thermal paste tip: for laptops HP with processors Intel 11th–13th generation or AMD Ryzen 5000/6000 choose a paste with high thermal conductivity (10+ W/mK), since they heat up more than their predecessors. Avoid cheap silicone pastes - they dry out in 6-12 months.

💡

If the housing screws HP "stuck", drop on them WD-40 and wait 5-10 minutes. Do not use excessive force - stripped threads in the aluminum housing may require replacement of the entire bottom cover.

4. Step-by-step disassembly of the laptop HP: removing the cooler

The disassembly process differs depending on the laptop series. Below are universal instructions suitable for most models (Pavilion, Omen, ProBook, Envy). For ultrabooks (Spectre, EliteBook) additional steps may be required.

Step 1: Turn off the power and remove the back cover

  1. Turn off the laptop, disconnect the charger and remove the battery (if it is removable).
  2. Turn the laptop over and remove all the screws on the bottom cover. In models HP Omen some screws may be hidden under the rubber feet.
  3. Using a plastic spatula, carefully pry the cover off, starting at the corner near the screen hinges. Be careful - the latches are fragile!

Step 2: Removing the Cooler

  1. Disconnect the cooler cable from the motherboard. The connector is usually located near the heatsink and is marked as FAN or CPU_FAN.
  2. Unscrew the screws securing the cooler to the radiator (usually 3-4 pieces). On some models (HP Pavilion Gaming) the radiator and cooler are a single unit - you will have to remove it entirely.
  3. If the cooler is stuck to the radiator, do not pull it by force - warm it up with a hair dryer 60–80°C within 1–2 minutes.

Step 3: Cleaning and Preparation

Before installing a new cooler:

  • 🧹 Remove dust from the radiator with compressed air or a soft brush.
  • 🧴 Wipe off old thermal paste from the processor and GPU with alcohol. Do not use acetone - it can damage plastic elements!
  • 🔍 Check the thermal pads on the chipset and video memory. If they become hard or cracked, replace them.
What to do if the cooler is soldered to the radiator?

Some models HP (For example, Spectre x360 13 or Envy 13) the cooler is soldered to the heat pipes. To replace you will need:

1. Soldering gun with temperature 350–400°C.

2. Solder Sn63Pb37 and flux (for example, Amtech NC-559-ASM).

3. Experience in soldering SMD components - without it there is a risk of damaging the radiator or motherboard.

If you are not confident in your skills, contact the service. The cost of such a replacement is from 3 000 ₽.

5. Installing a new cooler and assembling the laptop

The installation process is the reverse of disassembly, but there are several critical nuances:

  1. Applying thermal paste: for processors Intel A pea-sized drop is enough (4–5 mm), for AMD Ryzen (for example, in HP Omen) - slightly larger due to the larger lid. There is no need to spread the paste - it will flatten evenly when tightening the radiator.
  2. Connector connection: Make sure the cooler connector fits tightly into the socket on the motherboard. On models HP ProBook The connector may be upside down - check the marks + And –.
  3. Screw tightening: twist them criss-crossto avoid skewing the radiator. The tightening force is moderate (do not over-tighten, otherwise you may damage the processor crystal!).

After assembly:

  • 🔌 Connect the charger and start the laptop.
  • 🌡️ Check temperatures in HWMonitor or Open Hardware Monitor. In idle mode the CPU should be no higher 40–50°C, under load - up to 75–85°C (depending on the model).
  • 🎛️ Make sure the cooler regulates the rotation speed. If it constantly runs at maximum speed, check the settings in the BIOS (Fan Control → Automatic).
⚠️ Attention: If after replacing the cooler the laptop HP does not turn on or the fan does not rotate, check:
  • The cooler connector is connected correctly (reconnect it).
  • Integrity of the cable - sometimes contacts are damaged during disassembly.
  • BIOS Settings: On some models (HP EliteBook 840) after replacing the cooler, you need to reset the BIOS (remove the battery CR2032 for 10 minutes).
💡

If the processor temperature remains high after replacing the cooler (>80°C during idle time), the problem may not be in the fan, but in dried thermal paste under the chipset or faulty heat pipes. In this case, a complete overhaul of the cooling system is required.

6. Prevention of overheating: how to extend the life of a cooler

To make your new fan last longer:

  • 🧹 Clean your laptop every 6 months. Use a can of compressed air (eg Kontakt Chemie) or a vacuum cleaner with reverse draft. Do not blow with your mouth - saliva contains acids that are harmful to electronics!
  • 🖥️ Use a cooling pad with additional fans (eg Cooler Master NotePal X3). This will reduce the load on the stock cooler.
  • 🔄 Update your BIOS. In new versions for HP fan control algorithms are often improved. Download firmware only from official website.
  • 🛠️ Control the load. In games or rendering, limit FPS (via MSI Afterburner or RivaTuner) to reduce heat generation.

For models with passive cooling (For example, HP Stream 11) or ultrabooks (HP Spectre Folio) the cooler cannot be replaced - it uses a heat pipe without a fan. In this case, only an external cooler or limiting performance through power settings will help (Energy saving balance on Windows).

7. Frequent mistakes when replacing a cooler with HP

Even experienced users make mistakes that lead to repeated overheating or breakdown of the laptop. Here are the most common:

Error Consequences How to avoid
Using incompatible thermal paste (such as liquid metal on an aluminum heatsink) Radiator corrosion, current leakage to motherboard For HP with aluminum radiators, use only silicone or carbon pastes
Retightening radiator screws Cracks on the board, chip of the processor chip Tighten the screws to no more than 0.5–0.6 Nm (use a torque screwdriver)
Connecting the cooler in reverse polarity The fan does not rotate or operates at maximum speed Check the tags +/– on the cooler connector and cable
Forgot to connect the cooler cable The laptop does not turn on or turns off after 5–10 seconds Always check the connections of all cables before first assembly

Another typical problem is incorrect assembly of the case. For example, if you forget to install rubber gaskets under the screws (found in HP Omen), this may cause vibration and additional noise. All gaskets and latches must be in place!

Frequently asked questions (FAQ)

Is it possible to replace the cooler on a laptop? HP without disassembling the entire body?

No, in 99% of cases complete disassembly is required. Exception - some models HP Pavilion with a separate hatch for access to the cooler (for example, Pavilion 15-cw1xxx). However, even in this case, you will have to disconnect the fan cable from the motherboard.

How much does it cost to replace a cooler at a service center? HP?

The cost depends on the model:

  • Budget laptops (HP 250 G8, 255 G8): 1 500–2 500 ₽.
  • Gaming (Omen 15, Pavilion Gaming): 3 000–5 000 ₽ (due to the complex cooling system).
  • Premium Series (Spectre, Envy): 5 000–8 000 ₽ (soldering required).

The price includes labor and spare parts. Replacing it yourself will cost less, but the risk of damaging the laptop is higher.

How to check that the new cooler is working correctly?

After replacement:

  1. Start the laptop and listen to the noise - it should be smooth, without squeaks.
  2. Install HWMonitor and load the processor (for example, with a test Prime95). The temperature should not exceed 85°C for Intel And 90°C for AMD.
  3. Check the cooler rotation speed at SpeedFan. It should increase smoothly with load.

If the laptop turns off when it gets too hot 100°C — the cooler cannot cope (perhaps it is connected incorrectly or is incompatible).

What should you do if, after replacing the cooler, your laptop becomes noisier?

Possible reasons:

  • The cooler is installed crookedly - check the gaps between the blades and the body.
  • A non-original fan with a different speed is used. For example, a cooler from Dell may rotate faster than stock HP.
  • Dust got into the bearing during installation. Try blowing out the cooler with compressed air.
  • The BIOS mode is enabled "Performance Cooling" - switch to "Balanced".

If the noise persists, return the old cooler and check to see if there was a problem.

Is it possible to use a cooler from another laptop (for example, Lenovo or Asus)?

Theoretically yes, if they match:

  • Dimensions (±1 mm).
  • Connector type (2-pin, 3-pin or 4-pin).
  • Supply voltage (usually 5V or 12V).

However, even if the parameters match, there may be problems:

  • Incompatible with EC controller (the cooler will not regulate the speed).
  • Different air direction (blow instead of suck).
  • Lack of speed sensor (the laptop will assume that the cooler is faulty and turn off).

We recommend using only original or certified spare parts.
