Repasting
The process of removing old dried thermal paste and applying fresh compound. Typically reduces CPU temperatures by 10–20°C. Recommended every 3–5 years, or immediately if your laptop is throttling.

Repasting is the service of removing the heatsink, cleaning off old dried thermal paste from the chip surface and heatsink, and applying fresh high-quality thermal compound. It is one of the most cost-effective thermal services available — temperature reduction is immediate and significant.
Many laptops that were throttling severely restore full sustained performance after a repaste.
- Laptop is 3+ years old and running noticeably hotter than before
- CPU/GPU temperatures regularly exceed 85–90°C under load
- Performance drops after 10–15 minutes of sustained use (thermal throttling)
- Fan runs at maximum speed almost constantly
- Laptop shuts down unexpectedly during demanding tasks
DISASSEMBLE
Remove bottom cover and access the heatsink assembly
CLEAN
Remove old paste from chip and heatsink with isopropyl alcohol
APPLY
Apply fresh Thermal Grizzly paste in correct amount and pattern
TEST
Reassemble and run stress test to verify temperature reduction
How much does repasting reduce laptop temperatures?
Typically 10–20°C under sustained load. A laptop running at 95°C may drop to 70–75°C after a quality repaste, fully eliminating throttling.
Is repasting risky for the laptop?
In experienced hands, very low risk. For thin and light laptops with complex disassembly, professional repasting is recommended over DIY.
Should repasting and fan cleaning be done together?
Yes — always. Since the laptop is already opened, cleaning the fan and heatsink vents at the same time adds minimal time but addresses all thermal issues.
