Xbox One X Thermal Paste Replacement
Fix Overheating, Reduce Fan Noise, and Restore Peak Performance
The Xbox One X (model 1787 'Project Scorpio') packs a 6 TFLOP GPU and custom 8-core CPU into a compact form factor. That processing power generates significant heat, and Microsoft uses a vapor chamber cooling solution with factory-applied thermal paste. After 4-6 years, that paste dries out, creating a thermal barrier between the APU die and the vapor chamber. The result: sustained fan noise, thermal throttling during demanding games, and eventual thermal shutdown. Replacing the thermal paste drops APU temperatures by 10-20°C and restores quiet, stable operation.
What Causes Thermal Paste Degradation on Xbox One X
Microsoft applies a mid-grade thermal interface material (TIM) at the factory. This paste is designed for manufacturing efficiency, not long-term performance. Over 4-6 years of heat cycling (heating during play, cooling when off), the paste's silicone and zinc oxide compounds separate, dry, and crack. Dried paste has 5-10x lower thermal conductivity than fresh paste, turning it from a heat conductor into a heat insulator.
đ§ Xbox One X Cooling Architecture
- Custom vapor chamber (not standard heatpipes) spans the entire APU surface
- Centrifugal blower fan pushes air through heatsink fin stack
- Thermal paste sits between the APU die (bare silicon) and the vapor chamber copper base
- Secondary thermal pads cover RAM chips and voltage regulators (replace these too if they are cracked)
How to Confirm Thermal Paste Needs Replacement
Thermal Paste Degradation Symptoms
- âFan runs at near-maximum speed within 5-10 minutes of starting a game
- âConsole top panel is too hot to comfortably rest your hand on
- âGames stutter or show framerate drops after 15-30 minutes (thermal throttling)
- âConsole shuts down during graphically intensive games (Red Dead Redemption 2, Forza Horizon)
- âConsole has been in use for 4+ years without thermal paste service
- âFan noise has gradually increased over months

Before You Start: Important Warnings
â ī¸ Vapor Chamber Caution
The Xbox One X uses a vapor chamber, not standard heatpipes. The vapor chamber is a sealed unit containing a small amount of liquid coolant. Do NOT puncture, bend, or pry the vapor chamber. If the copper surface is dented or punctured, the vapor chamber is destroyed and must be replaced (expensive and hard to source).
Step-by-Step Thermal Paste Replacement
Complete Thermal Paste Service
Full teardown with paste and optional thermal pad replacement
Step 1: Complete Disassembly
Power off and unplug the console. Wait 5 minutes. Remove rear and bottom T9 screws. Pry off the top panel by unclipping the plastic tabs along the edges. Remove the Blu-ray drive connector and eject button cable. Remove the RF shield and internal metal frame screws. Lift the motherboard out of the lower shell.
Step 2: Remove the Heatsink/Vapor Chamber
Flip the motherboard over. The vapor chamber is secured by spring-loaded T9 screws around the APU. Loosen each screw one quarter-turn at a time in a cross pattern (prevents uneven pressure on the die). After all screws are fully loosened, gently lift the vapor chamber straight up. Do not twist or slide it, as this can crack the APU die.
Step 3: Clean Old Thermal Paste
The APU die surface and the vapor chamber copper base will have old paste on them. The paste may be dry, cracked, or powdery. Apply IPA to a lint-free cloth and wipe the APU die surface gently. Use straight motions, not circular. Repeat until the die surface is mirror-clean. Clean the vapor chamber base the same way. Both surfaces should be shiny metal with zero residue.
Step 4: Inspect Thermal Pads (Optional)
While the heatsink is off, check the thermal pads on the RAM chips and voltage regulators. If they are cracked, compressed flat, or have transferred unevenly, replace them with matching-thickness pads (usually 1mm or 1.5mm). Measure the old pad thickness before removing.
Step 5: Apply New Thermal Paste
Apply a thin X pattern of thermal paste on the APU die. The Xbox One X APU is a large die (approximately 25x25mm), so a single pea-dot may not provide full coverage. The X pattern ensures paste reaches the corners. Do NOT spread the paste manually. Mounting pressure from the heatsink screws will spread it evenly.
Step 6: Reinstall the Vapor Chamber
Carefully lower the vapor chamber back onto the APU, aligning the screw holes. Hand-tighten each spring-loaded screw in a cross pattern, one quarter-turn at a time. Alternate between screws until all are fully tightened. This ensures even mounting pressure across the entire die surface.
Step 7: Reassemble and Test
Reassemble in reverse order: metal frame, RF shield, drive connector, shell halves; screws. Power on and run a demanding game for 30 minutes. Monitor fan behavior. The fan should run notably quieter than before the repair.
How to Test If the Repair Worked
Post-Repair Verification
- Fan Noise Reduction: The fan should no longer hit maximum RPM during normal gameplay. A properly cooled Xbox One X maintains moderate fan speed even during demanding titles.
- Temperature Check: Touch the top panel after 30 minutes of gaming. It should feel warm but significantly cooler than before the repair.
- Stability Test: Play a graphically demanding game (Red Dead Redemption 2, Forza Horizon 5) for 60+ minutes with no shutdowns, stuttering, or thermal throttling.
- Boot Time: A thermally stressed console sometimes has slower boot times due to power management throttling. Post-repair, boot times should return to normal.

Frequently Asked Questions
Q: Should I use liquid metal on the Xbox One X?
No. The Xbox One X vapor chamber uses a copper base, which is compatible with liquid metal. But if any liquid metal leaks onto the surrounding PCB components, it will cause shorts and permanent damage. The risk is not worth the 2-3°C improvement over premium thermal paste. Stick with paste.
Q: How do I know if my thermal paste is dried out without opening the console?
If your Xbox One X is 4+ years old AND exhibits loud fan noise, thermal shutdowns, or game stuttering after extended play, the thermal paste is almost certainly degraded. There is no external way to measure paste condition. The symptoms are reliable indicators.
Q: What if I accidentally apply too much thermal paste?
Excess thermal paste squeezes out around the edges of the APU die when the heatsink is mounted. If you use non-conductive paste (Arctic MX-4/5, Noctua NT-H1/H2), excess paste causes no damage. It just makes a mess. If you use conductive paste (liquid metal, silver-based), excess can short nearby components.
Q: Can I reuse the old thermal pads on the RAM chips?
If the pads are still soft, pliable, and have not cracked or torn, you can reuse them. If they are hard, crumbly, or have lost their original shape, replace them. Degraded thermal pads on RAM chips cause separate overheating issues that thermal paste replacement alone will not fix.
Thermal paste replacement is the single most effective maintenance you can perform on an aging Xbox One X. A $10 tube of paste and 30 minutes of work drops temperatures by 10-20°C and transforms your console from a jet engine back to a quiet gaming machine.
Test Your Gaming Setup
After restoring your console's cooling, verify your controllers are performing at peak accuracy.
