7STARLAKE provides real lab testing figures to show how CPU performance is with each tailor made thermal kits as important references and design guide for system engineers. For system integration, the crucial challenge is the operation performance under high temperature, thus 7STARLAKE conducts long time experiments to make sure the superior testing result for all critical missions. By revealing temperature at processor T junction, processor die and heat sink, 7STARLAKE is able to analyse the thermal solution we designed achieves maximum efficacy and observe CPU performance. The high temperature testing takes 5 hours which at each temperature point we burn in INS8321B for one hour, from +50 to +85°CThermal Measurement
Thermal Solution
Efficient thermal solution for maximum heat dissipation:
What composes of a perfect thermal solution? With ROCS235B, it’s all about the incorporation of different heat dissipating part to create an almighty thermal conduction power. Honeycomb dissipating vents are constructed on the top and the sides to increase the dissipating area. The honeycomb cells can achieve faster heat dissipation without occupying much space. Two heat spreaders and two heat sinks are installed to create a magnificent ventilating structure. Six heat pipes are implemented to conduct the heat to the thermal modules on the two sides of the system. This phenomenal combination can bring out the best dissipating effect.
Honeycomb Dissipating Vents
The honeycomb vents are pre-drilled in rigid aluminum frames to fasten thermal convection and the airflow that will astonishingly enhances ventilation. The enclosure features large, open honeycomb vents on the top, sides, front and back instead of fan solution that allows natural convection cooling that gather dust easily. This heat dissipating design can dispel heat quickly through the honeycomb cells without occupying much space. The unique design enables greater airflow through the entire area of the honeycomb surface. The metalized polymeric honeycomb also brings up excellent rigidity and pressure resistance.
Passive Heat Spreader
Heat spreader is known for improving the distribution of heat. Our tailor-made heat spreader is made with precision and consideration to every detail.
- It contains % of aluminum, the height is mm and it weighs g.
- Excellent performance in heat absorption
Dual Sided High Efficiency Thermal Modules
Dual Sided Thermal Modules can transmit the heat transferred by the heat pipes. Fen shaped design helps to emit the heat to the surrounding air, then release through the honeycomb dissipating vents on the front, back, and the sides.
Six Copper Heat Pipes
Six heat pipes are installed to ensure 100% tight integration for superior heat dissipation. Copper heat pipes transfer heat from the heat sources (e.g. CPU, chipset) to the thermal modules on the sides. Two-phase heat transfer involves the liquid-vapor phase change of a working fluid.
- 8.0 mm diameter heat pipe, 99.9% purity of copper
- High heat conductivity coefficient up to 5000!
Aluminum Heat Sink
Heat sink is known for its ability to improve the distribution of heat. Our tailor-made heat sink is made with aluminum. It can dissipate the heat in the quickest fashion.
- It contains 96% of aluminum, 48mm in height and weighs 103.5g.
- Consumes shorter heat dissipating time owing to lower metal density
