Tesla Referral Compute Cards Why Buy This ✓ Dual 40mm High-RPM Fans — strong airflow for efficient compute GPU cooling ✓ Ultra-Short Form Factor — minimal length extension, fits tight chassis ✓ Wide
Tesla Referral Compatibility — works with A100, H100, H80, L40, A30 and more ✓ Open Box Value — fully functional, inspected ready to install What You'll Get
An ultra-short dual-fan active cooling upgrade kit designed for NVIDIA Tesla Referral A-series, H-series and L-series compute GPUs. This kit mounts two high-speed 40mm fans with a focused air duct directly onto the GPU heatsink, delivering concentrated airflow to reduce core temperatures during sustained AI training, inference and scientific computing workloads.
The ultra-compact design adds only minimal length to the card, making it suitable for cramped server chassis, compact workstations and small-form-factor builds. The duct structure directs all fan airflow through the heatsink fins for maximum cooling efficiency, instead of wasting airflow into open air.
This is an open-box item. The cooling assembly has been inspected and is fully functional. Minor cosmetic imperfections may exist on 3D printed components, but this does not affect performance or installation.
