RTX 4090 Blower
NVIDIA Graphics Card
The blower (turbo) version of the GeForce RTX 4090 uses a single-fan rear-exhaust cooler that pushes hot air straight out of the chassis - the key requirement for multi-GPU and high-density workstation builds. Core specifications match the reference card: Ada Lovelace architecture, 16,384 CUDA cores, 24GB of GDDR6X memory and 1,008 GB/s of bandwidth. The dual-slot thickness allows several cards in one system, which is why it is commonly chosen for AI training and inference, deep-learning development machines and rendering farms.
