**Why Reapply Thermal Paste?**
The thermal paste acts as a bridge, filling the microscopic gaps between the CPU/APU and the heatsink. Air is a poor conductor of heat, so without proper thermal paste, heat cannot efficiently transfer from the processor to the heatsink, causing the components to overheat. Overheating can lead to:
* **Loud Fan Noise:** The PS4’s fan will spin at maximum speed to try to cool down the overheated components, resulting in excessive noise.
* **Game Crashes:** Overheating can cause instability, leading to games crashing or freezing.
* **Performance Throttling:** To prevent permanent damage, the PS4 will reduce the performance of the CPU and GPU, resulting in stuttering and lag.
* **Hardware Damage:** Prolonged overheating can eventually damage the CPU, GPU, or other components, leading to permanent failure.
**Is it Really Thermal Paste? Ruling Out Other Issues**
Before diving into the thermal paste replacement, consider these other potential causes of PS4 overheating and loud fan noise:
* **Dust Buildup:** Dust accumulates inside the PS4 over time, blocking airflow and trapping heat. Regularly cleaning the console’s vents and internal components can significantly improve cooling.
* **Software Issues:** Sometimes, software bugs or corrupted game files can cause the PS4 to work harder than necessary, generating more heat. Try reinstalling the game or performing a system software update.
* **Faulty Fan:** A malfunctioning fan might not be spinning at the correct speed or could be making excessive noise. If the fan is the issue, it will need to be replaced.
If you’ve ruled out these other possibilities, then reapplying thermal paste is likely the next step.
**Tools and Materials You’ll Need**
Before you begin, gather all the necessary tools and materials:
* **Phillips Head Screwdriver:** A set with various sizes is recommended to handle different screws inside the PS4. A magnetic screwdriver will be very helpful.

2. **Disconnect the Power Supply Cables:** Carefully disconnect the power supply cables from the motherboard. There are usually two or three connectors. Gently squeeze the clips on the connectors to release them. Make a note of which connector goes where, or take a picture for reference.
3. **Remove the Power Supply Screws:** Use a Torx TR9 security screwdriver to remove the screws securing the power supply to the chassis. These screws are usually located around the perimeter of the power supply.
4. **Lift Out the Power Supply:** Carefully lift the power supply out of the PS4. Be mindful of any remaining cables or connectors that might be attached.
**Step 4: Removing the Blu-ray Drive (Optional, but Recommended)**
Removing the Blu-ray drive provides easier access to the motherboard and heatsink, making the thermal paste application process simpler. However, if you’re comfortable working around it, you can skip this step.
1. **Disconnect the Blu-ray Drive Cables:** Disconnect the two ribbon cables connecting the Blu-ray drive to the motherboard. These cables are delicate, so be careful not to damage them. Gently lift the retaining clips on the connectors and pull the cables out.
2. **Remove the Blu-ray Drive Screws:** Use a Phillips head screwdriver to remove the screws securing the Blu-ray drive to the chassis. These screws are usually located on top of the drive.
3. **Lift Out the Blu-ray Drive:** Carefully lift the Blu-ray drive out of the PS4.
**Step 5: Removing the Heatsink**
1. **Locate the Heatsink:** The heatsink is the large metal component that sits directly on top of the CPU/APU. It usually has several copper heat pipes running through it.
2. **Remove the Heatsink Screws:** Use a Phillips head screwdriver to remove the screws securing the heatsink to the motherboard. These screws are usually arranged in a specific order, so pay attention to their placement or take a picture for reference. Loosen the screws in a diagonal pattern, a little at a time, to ensure even pressure release. This helps prevent warping or damage to the CPU/APU.
3. **Detach the Heatsink:** The heatsink might be stuck to the CPU/APU due to the dried thermal paste. Gently twist the heatsink back and forth to break the seal. Avoid pulling straight up, as this could damage the CPU/APU. If it’s really stuck, you can use a heat gun on low setting to gently warm the heatsink, which can help loosen the thermal paste. Be extremely careful not to overheat the components.
4. **Lift Off the Heatsink:** Once the heatsink is detached, carefully lift it off the CPU/APU.
**Step 6: Cleaning the Old Thermal Paste**
1. **Apply Isopropyl Alcohol:** Dampen a lint-free cloth or coffee filter with isopropyl alcohol (90% or higher).
2. **Clean the CPU/APU:** Gently wipe the surface of the CPU/APU to remove the old thermal paste. Use circular motions and apply light pressure. You might need to repeat this process several times to remove all the residue. Use cotton swabs to clean hard-to-reach areas.
3. **Clean the Heatsink:** Clean the surface of the heatsink that comes into contact with the CPU/APU using the same method. Make sure to remove all traces of old thermal paste.
4. **Inspect and Ensure Cleanliness:** Once you’ve cleaned both surfaces, inspect them carefully. There should be no visible residue of old thermal paste. The surfaces should be clean and smooth.
5. **Allow to Dry:** Let the isopropyl alcohol evaporate completely before proceeding to the next step. This usually takes a few minutes.
**Step 7: Applying New Thermal Paste**
There are several methods for applying thermal paste. The most common and recommended methods are:
* **Dot Method:** Place a small, pea-sized dot of thermal paste in the center of the CPU/APU.
* **Line Method:** Apply a thin line of thermal paste down the center of the CPU/APU.
* **Spread Method:** Use a credit card or a specialized thermal paste spreader to evenly spread a thin layer of thermal paste across the entire surface of the CPU/APU. This method is more complex and requires more practice.
**Applying the Thermal Paste (Dot Method):**
1. **Apply a Pea-Sized Dot:** Squeeze a small, pea-sized dot of thermal paste onto the center of the CPU/APU. Less is more. Too much thermal paste can be just as bad as not enough.
**Why the Dot Method is Recommended:**
The pressure from the heatsink when it’s reattached will spread the thermal paste evenly across the surface of the CPU/APU. This method is simple, effective, and minimizes the risk of applying too much thermal paste.
**Step 8: Reattaching the Heatsink**
1. **Position the Heatsink:** Carefully position the heatsink on top of the CPU/APU, aligning the screw holes. Make sure the heatsink is seated correctly.
2. **Secure the Heatsink:** Reinstall the heatsink screws in the same order you removed them. Tighten the screws in a diagonal pattern, a little at a time, to ensure even pressure. Avoid overtightening the screws, as this could damage the CPU/APU or the motherboard. Tighten them until they are snug, but not overly forced.
**Step 9: Reassembling the PS4**
1. **Reinstall the Blu-ray Drive (If Removed):** Place the Blu-ray drive back into its original position and secure it with the screws you removed earlier. Reconnect the ribbon cables to the motherboard.
2. **Reinstall the Power Supply:** Place the power supply back into its original position and secure it with the Torx screws. Reconnect the power supply cables to the motherboard.
3. **Reattach the Top Cover:** Align the top cover with the chassis and slide it forward until it clicks into place. For CUH-1200 models, press down on the edges of the cover to snap the clips back into place.
4. **Reinstall the Rear Screws:** Flip the PS4 upside down and reinstall the screws on the back. Reattach the rubber feet.
**Step 10: Testing the PS4**
