Engineering overview

Thermal: rated 225 W in a 1U chassis with front-to-back airflow. Fin thickness 0.3 mm, fin spacing 1.65 mm; the fin stack is sized for the static pressure of standard server fan walls.
Heat path: Aluminium fins, heat pipes.
Airflow: passive design — relies on chassis fans; keep the fin direction aligned with the chassis airflow.
Mechanical: 118 × 78.9 × 26 mm; retention hardware for AMD SP6 included.
Customisation: fin height, fan selection, surface finish and pre-applied TIM per project; drawings and 3D models on request.

Ordering & RFQ

How to order: quote model ASP6-1B04 with quantity and target chassis. Samples 1–5 pcs; production quantities after drawing approval.

RFQ checklist: CPU model and TDP, chassis height and airflow direction, available fan headers and power budget, inlet air temperature, expected quantity. Send a STEP/PDF of your chassis if fin orientation or height matters.

FAQ

Does the TDP rating guarantee CPU temperature? No — the rating is the reference load; final CPU temperature depends on chassis airflow, inlet temperature and fan curve. We validate against your system data on request.

Can the mounting be adapted? Yes — retention hardware is platform-specific; alternative brackets and custom pitches are handled per drawing.

What is included? Heatsink/cooler, mounting hardware and thermal paste (or pre-applied TIM on request).
