ASUS Laptop Thermal Repaste — PTM7950 / Liquid Metal Service
Last Updated:
ASUS gaming laptop factory paste degrades within 18-24 months under sustained gaming load. PTM7950 re-paste + heat-exchanger clean + fresh VRAM pads: $280 flat. Liquid metal upgrade available for X170-class top-spec users wanting maximum thermal performance.
Common Issues & How We Fix Them
What’s included ($280)
Full 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 temperature report.
Liquid metal upgrade ($380-$420)
Conductonaut on CPU die. PTM stays on GPU for safety. ~5°C better than PTM7950 on CPU side; requires more careful long-term maintenance.
Typical results by line
Strix Scar 17/18: 18-25°C drop. Zephyrus M16: 15-22°C. TUF: 15-20°C. G14 (vapor chamber): 10-15°C.
When repaste isn’t enough
If fans / chamber / dust are the constraint, full thermal service required.
Service intervals
Heavy gaming: every 18-24 months. Light use: 36-48 months. PTM7950 doesn’t pump out, so service intervals are longer than regular paste.

Frequently Asked Questions
ASUS Laptop Thermal Repaste faults we repair every week
Factory thermal paste pump-out
Symptom: CPU and GPU temperatures rise 20-30°C within 18-24 months of heavy gaming, causing thermal throttling and fan ramp-up
How we fix it: Complete disassembly, isopropyl removal of degraded paste, application of PTM7950 phase-change pad to CPU/GPU dies and fresh high-conductivity pads on VRAM modules.
Repair or replace? repair
Dried VRAM thermal pads
Symptom: Memory junction temperatures exceed 95°C under load, visible as stuttering in GPU-heavy titles on Strix Scar and TUF models
How we fix it: Remove old pads, measure thickness with digital callipers, fit new 1.5-2.0 mm Thermalright 12.8 W/mK pads cut to exact die footprints.
Repair or replace? repair
Heat-exchanger dust blockage
Symptom: Exhaust air 15°C hotter than ambient and fans at 100 % even at idle after 12 months of use
How we fix it: Compressed-air and anti-static brush cleaning of fins, followed by isopropyl flush and compressed-air drying before reassembly.
Repair or replace? repair
Vapour-chamber delamination on G14
Symptom: Hotspot delta of 25°C+ between CPU die centre and edges despite clean fans, common on 2021-2023 AMD models
How we fix it: Full lid removal, inspection for chamber separation, replacement of entire heatsink assembly if delaminated rather than repaste alone.
Repair or replace? Depends
Pump-out around liquid-metal edges
Symptom: Sudden 10-15°C spikes on CPU after 6-9 months when Conductonaut was applied without proper barrier on X170-series
How we fix it: Re-clean die and IHS, apply fresh Conductonaut only to CPU, PTM7950 on GPU, and add Kapton tape dam around die perimeter to contain migration.

ASUS Laptop Thermal Repaste — your questions answered
Will repaste help my ROG laptop?
If your ROG is 18 months or older and you game regularly, a PTM7950 repaste almost always lowers temperatures 15-25 °C. The service includes full disassembly, heat-exchanger cleaning and fresh VRAM pads for $280 flat with a 90-day warranty.
Can I use liquid metal on Zephyrus G14?
Liquid metal is generally not recommended on the G14 due to the tight chassis and AMD APU layout, which increases migration risk. PTM7950 remains the safer, lower-maintenance choice and still delivers a 10-15 °C improvement.
How often should I repaste an ASUS gaming laptop?
Heavy daily gaming warrants a PTM7950 service every 18-24 months, while lighter use stretches to 36-48 months. PTM7950 resists pump-out, so intervals are longer than with conventional paste.
What temperature drop can I expect on a Strix Scar 17?
Owners of the Strix Scar 17 and 18 typically see 18-25 °C lower CPU and GPU peaks after a PTM7950 repaste plus chamber clean. Results are confirmed with before-and-after stress-test logs.
Do you offer onsite service for thermal repaste?
Yes, our technicians perform the full PTM7950 repaste onsite in Sydney metro for $320-$360. The job includes the same disassembly, cleaning and 30-minute stress test as workshop repairs, completed same day.
Is the 90-day warranty transferable if I sell the laptop?
The 90-day warranty covers parts and labour and stays with the repaired machine. If you sell within the period, the new owner can still claim the remaining coverage with proof of original invoice.
