Laptop thermal paste
Thermal paste for laptop repaste
Thermal paste for laptop repaste fills the microscopic gaps between a compatible chip surface and heatsink. ARCTIC MX-6 and Noctua NT-H2 are conventional non-conductive compounds to compare when the laptop’s service instructions call for paste.

ARCTIC MX-6 or Noctua NT-H2 for a paste interface
Compare pack quantity, included cleaning materials and storage instructions. A small syringe can suit an occasional laptop job; extra compound is useful only if you service more devices.
Useful for a planned heatsink service where conventional paste is the specified interface and the assembly can be refitted correctly.
Match the interface material specified by the laptop
Use the interface material required by the service guide. Paste, thermal pads, putty and phase-change materials have different jobs and thickness requirements; retain the specified arrangement around memory and power components.
MX-6 and NT-H2: useful specifications beyond a headline number
ARCTIC publishes MX-6 density of 2.6g/cm³ and viscosity of 4,500 poise. Noctua describes NT-H2 as electrically non-conductive and non-corroding. These material details are more useful than assuming a single advertised conductivity number predicts the result inside every laptop.
A repaste result depends on contact, application, mounting pressure and the rest of the cooling system. Compare the compound’s instructions and the laptop’s original interface before choosing.
Syringe size, cleaning and heatsink contact
Select enough compound for the intended chips and follow the manufacturer’s application guidance. Remove the old material as the service guide directs, then refit the heatsink in the specified screw order.
Pads or putty on neighbouring components maintain their own gaps. Keep those interfaces at the correct locations and thicknesses so the heatsink can make the intended contact with the CPU and GPU.
Laptop thermal paste specifications in practice

Laptop thermal paste FAQ
Can thermal paste replace a thermal pad?
No. Pads bridge a specified gap. Paste is intended for a thin contact interface and does not replace the required pad thickness.
Should I repaste my laptop?
Only when symptoms point to paste/contact after easier checks. Heat alone does not prove paste is the problem.
Do I need thermal pads too?
Some laptops use pads with exact thickness. Guessing thickness can make temperatures worse.
Which syringe size suits occasional repairs?
Choose a small pack when you only plan one or a few service jobs. A larger pack is convenient for repeated use; compare storage instructions and included cleaning materials.
