Engineering overview

Thermal: rated 135 W in a 2U chassis with front-to-back airflow. Fin thickness —, fin spacing —; the fin stack is sized for the static pressure of standard server fan walls.
Heat path: Copper.
Fan: PWM 2100-6800RPM, 4pin PWM, Double Ball Bearings, 12 V — speed follows the board fan curve.
Mechanical: 93 × 90 × 67 mm; retention hardware for AMD AM4 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 AAM4-1Z03 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).

How the AAM4-1Z03 compares with related models

Compared with the AAM4-1Z04, the AAM4-1Z03 differs in rated thermal load TDP (135 W vs 95 W), overall size L × W × H (93 × 90 × 67 mm vs 104 × 75 × 67 mm), base / fin material (Copper vs Copper base, aluminium fins).

By rated thermal load TDP, the AAM4-1Z03 is rated at 135 W; the next lower rating in this range is the AAM4-1Z04 (95 W). Select on the confirmed duty point rather than on the headline rating alone.
