We address every component of the cooling system to eliminate overheating permanently.

Fan Cleaning & Replacement

Clogged fans are the #1 cause of overheating. We clean dust buildup and replace failed or noisy cooling fans on all laptops and desktops.

Thermal Paste Replacement

Old or dried-out thermal paste causes CPUs to run dangerously hot. We clean and reapply high-quality thermal compound to restore proper heat transfer.

Heat Sink Service

We clean, inspect, and reseat heat sinks to ensure maximum contact with the CPU and GPU for optimal cooling performance.

GPU Overheating Repair

Graphics cards can overheat due to clogged fans, failed thermal pads, or poor case airflow. We address GPU cooling issues on desktops and laptops.

Thermal Throttling Resolution

Is your computer running slowly under load? Thermal throttling reduces CPU speed to prevent damage from heat. We eliminate the root cause.

Airflow & Case Optimization

For desktops, poor case airflow causes chronic overheating. We optimize fan placement, airflow direction, and cable management.
