Xbox 360 Heat Sink Function, Types & Maintenance Guide

Material: Aluminum (early) or Copper base + Aluminum fins (later).
Thermal Interface: Thermal paste (factory) or pads between die and sink.
Airflow: 12V radial fan pulls air through fins, exhausts rear.

Function

The heat sink absorbs and dissipates heat from the CPU and GPU (the two main chips) to prevent thermal throttling and solder fracture (RRoD).

Model	Heat Sink Design	Effectiveness
Xenon/Zephyr (Launch)	Small Al, X-clamp mount	Poor → High RRoD rate
Falcon/Jasper (65/45nm)	Larger Cu base, heatpipes (Jasper)	Much better
Slim (Valhalla)	Unified CPU/GPU (CGP) → Single large sink	Best stock cooling

Annual Clean: Compressed air through vents (fan running).
Thermal Paste Replacement: Every 3–5 years. Use high-quality non-conductive (Arctic MX-6, NT-H2, GD900). Remove old paste fully (IPA 99%).
X-Clamp Replacement (Advanced): Replace X-clamps with M5 bolts/nuts/washers for even pressure—reduces warping.

A cool Xbox 360 lives longer.
