About the service
PROTECT YOUR PC FROM OVERHEATING
Dust buildup inside heat sinks obstructs airflow, causing cooling fans to spin at maximum speed without lowering CPU temperatures.
Constant high heat degrades original thermal paste, causing the system to throttle CPU speeds or shut down to prevent damage.
Calistech carefully disassembles your laptop or desktop to clean heatsinks, fans, and vents of all residues.
We replace dried-up thermal paste with carbon-based high-thermal conductivity compounds to keep temperatures low.
