MSI Laptop Thermal Repaste — Cooler Boost Service
Last Updated:
MSI’s Cooler Boost architecture (multiple heatpipes, dual or triple fans, vapor chamber on top-spec, liquid metal on Titan) is excellent when new but factory paste degrades within 18-24 months of sustained gaming. PTM7950 re-paste + fresh VRAM pads + heat-exchanger clean: $280 flat. Liquid metal upgrade on top-spec Titan: $380-$420.
Common Issues & How We Fix Them
What’s included ($280)
Disassembly, paste removal, heat-exchanger clean, PTM7950 on CPU + GPU dies, fresh VRAM pads (Thermalright 12.8 W/mK), reassemble, 30-min stress test, before/after report.
Liquid metal (Titan GT77 top-spec)
Conductonaut on CPU die. PTM7950 on GPU. $380-$420 flat.
Typical results
Titan / Raider: 18-25°C drop. Stealth: 15-22°C (vapor chamber). Vector / mainstream: 15-20°C. Sword / Cyborg / Katana: 12-18°C (plastic chassis cooling limit).
Service intervals
Heavy gaming: 18-24 months. Light: 36-48 months.

Frequently Asked Questions
MSI Laptop Thermal Repaste faults we repair every week
Dried factory thermal paste
Symptom: CPU/GPU temps climb 15-25°C within 18-24 months of daily gaming, thermal throttling at 95°C+ under load
How we fix it: Disassemble cooler, remove old paste, clean dies and heatpipes, apply PTM7950 phase-change pad to CPU and GPU dies plus fresh high-conductivity VRAM pads.
Repair or replace? repair
Clogged heat-exchanger fins
Symptom: Fans ramp to 100% yet chassis stays hot; dust and lint block airflow on Stealth and Raider models
How we fix it: Remove fan assembly, use compressed air and soft brush to clear fins and vapour chamber surfaces before reassembly.
Repair or replace? repair
Degraded VRAM thermal pads
Symptom: Memory junction temps exceed 105°C on high-VRAM Titan and Raider models, causing memory errors during long renders
How we fix it: Replace original pads with 1.5 mm Thermalright 12.8 W/mK pads cut to exact VRAM footprint during repaste service.
Repair or replace? repair
Liquid metal migration on Titan GT77
Symptom: Conductonaut spreads onto surrounding components causing minor corrosion after 12-18 months heavy use
Repair or replace? Depends
Warped plastic chassis on Katana/Sword
Symptom: Cooler mounting pressure uneven after repeated heat cycles, lifting heatsink edges and raising idle temps 8-12°C
How we fix it: Straighten or replace warped bottom cover and re-torque heatsink screws to MSI spec torque sequence during repaste.
Repair or replace? repair
Fan bearing wear after repaste
Symptom: New lower temps achieved but one fan develops grinding noise within weeks on older Raider units
How we fix it: Replace affected 4-pin MSI fan assembly while cooler is removed; match RPM curve in BIOS/EC after install.

MSI Laptop Thermal Repaste — your questions answered
How often should I repaste my MSI gaming laptop?
Heavy daily gaming on an MSI Raider or Titan usually needs fresh PTM7950 every 18-24 months. Light use stretches to 36-48 months before throttling returns.
Is liquid metal safe on my Titan GT77?
It delivers the lowest temps but requires careful application and periodic inspection. Many owners switch back to PTM7950 for easier long-term maintenance.
Will repasting void my MSI warranty?
Opening the chassis for thermal work voids the remaining manufacturer warranty on most MSI models sold in Australia. We provide our own 90-day warranty on the repair.
What temperature drop can I expect after the service?
Titan and Raider models commonly drop 18-25°C under load. Stealth series with vapour chambers average 15-22°C. Plastic chassis models like Katana see 12-18°C improvement.
Do you offer onsite repaste for MSI laptops in regional areas?
Onsite service is available in capital city metro areas. Regional customers can use our prepaid courier drop-off option with 1-3 day workshop turnaround.
