HARDWARE IN DEVELOPMENT
PC

CPU & GPU cooling.
Compact system design.

Thermal hardware for high-density SFF systems. Low-profile and ultra-low-profile CPU coolers support AMD AM4/AM5 and Intel LGA 1700/1851, including vapor-chamber configurations for higher power envelopes. GPU coolers use model-specific copper cold plates or large-volume vapor chambers, 11-heatpipe architectures, and have been tested from 180 W to 350 W across the RTX 5060 Ti, 5070, 5070 Ti, and 5080.

Cooling and acoustics

Each GPU cooler is developed against the factory power limit of its target board. Prototypes are tested under sustained load for thermal stability, then acoustically compared with the original cooler under matched workloads and environmental conditions.

Product range in development. Release dates and availability will be announced.

02 / MANUFACTURING & CONSTRUCTION

Thermal architecture at the component level.

Vapor chambers, heatpipes, fin geometry, machining, and assembly are developed as a coupled thermal system.

Large-volume vapor chambers

80 × 110 mm copper vapor chamber, soldered directly into the heatpipe and fin-stack assembly.

Heatpipe assembly

Eleven gravity-resistant copper heatpipes distribute heat across the fin stack, with soldered joints across the mating thermal interfaces.

Electroless nickel finish

Fin stacks are electroless nickel plated after fabrication for uniform coverage across the completed thermal structure.

Post-skive machining

Fan pockets and model-specific mounting features are machined directly into the skived fin structure after fabrication.

Dense fin arrangement

1.2 mm fin pitch concentrates heat-transfer surface area within the fixed GPU cooler envelope.

01 / MACHINING

Model-specific machining

3-stage process

  1. Model-specific geometry

    Cold-plate contact area, mounting points, component clearances, and final stack height are defined around the target CPU socket or GPU PCB.

  2. Machined interfaces

    Contact surfaces, mounting features, and fan pockets are machined to the geometry of each cooler rather than shared across multiple models.

  3. Fit verification

    Mating surfaces, mounting alignment, and PCB or socket clearances are checked against the complete assembly before production release.

02 / PRODUCTION

Thermal assembly

3-stage process

  1. Matched thermal stack

    Cold plate or vapor chamber geometry, heatpipe routing, and fin-stack layout are matched to the model-specific thermal envelope.

  2. Soldered interfaces

    Base, heatpipes, and fin stack are joined across the thermal path to maintain consistent contact and mechanical stability throughout the assembly.

  3. Final finish

    Nickel plating and final surface work are completed while preserving fin spacing, component alignment, mounting access, and required clearances.

03 / INSPECTION

Quality control

3-stage process

  1. Dimensional inspection

    Critical dimensions, mounting locations, contact surfaces, plating coverage, fin geometry, and soldered interfaces are inspected before final assembly.

  2. Assembly verification

    Mounting alignment, component seating, fan clearance, and chassis fit are checked on the completed cooler.

  3. Load testing

    Each development configuration is run at its target factory power limit. Thermal and acoustic data are collected under controlled, repeatable conditions for comparison with OE hardware.
