Razer Blade Thermal Repaste — Liquid Metal + PTM7950 Service

Last Updated:

Razer Blade uses three different thermal compounds depending on SKU year and tier: (1) standard PTM7950 phase-change pads on Base models and Razer Book, (2) Conductonaut liquid metal on Advanced + top-spec Blades 2020-2023, (3) Conductonaut Extreme (newer formulation, less pump-out) on Blade 16/18 from 2024.

Pump-out is the dominant failure mode for liquid metal — the metal migrates out from under the IHS over 18-36 months, leaving an air gap. Symptoms: CPU temps spike to 95-100°C under any load, GPU temps generally still OK. Fix is a full pump-out clean (carefully remove migrated metal from surrounding SMD components) + re-application with proper nickel-foil dam to stop it migrating again.

Frequently Asked Questions

Standard repaste cost?

$320 for PTM7950 phase-change paste. $420 for Conductonaut / Conductonaut Extreme liquid-metal re-application (the higher cost reflects the additional clean-down + foil-dam work).

How often should I repaste?

PTM7950: 36-48 months. Conductonaut (older formulation): 24-36 months. Conductonaut Extreme: 36-48 months. We recommend a preventive check at 24 months regardless.

Can I downgrade from liquid metal to regular paste?

Yes, but you lose 5-10°C of headroom under sustained load. Some users prefer the simpler maintenance and slightly higher peaks. We can do PTM7950 in place of Conductonaut at the customer’s request.

What's the difference between Conductonaut and Conductonaut Extreme?

Extreme is a Thermal Grizzly newer formulation with significantly better pump-out resistance. Razer adopted Extreme on 2024+ Blades. We use Extreme on all liquid-metal re-applications going forward.

Will the warranty void if I get liquid-metal service from you?

If you’re inside Razer warranty, opening the chassis voids it. Out of warranty, no risk. We document everything for resale provenance.
