12GB GDDR6X for 1440p and 4K

The ASUS Dual GeForce RTX 4070 12GB GDDR6X targets gamers and creators who need 5888 CUDA cores and a 192-bit memory interface at 21 Gbps. It connects through PCI Express 4.0 and drives up to four displays via HDMI 2.1 and three DisplayPort 1.4a outputs. The Ada Lovelace architecture brings DLSS 3 frame generation and third-generation ray-tracing cores to this tier.

Cooling and acoustics

A 2.55 slot axial-tech cooler uses dual ball-bearing fans with a smaller hub and barrier ring to increase downward air pressure. 0dB technology stops the fans completely during light loads for silent operation. The design balances thermal headroom and power draw for typical gaming sessions.

Build and connectivity

IP5X dust resistance on the fan assembly helps maintain long-term airflow consistency. Auto-Extreme automated manufacturing and a 144-hour validation program reinforce solder joint reliability. The card occupies 2.55 slots, fits compact chassis, and provides HDMI 2.1 plus three DisplayPort 1.4a connectors for modern high-refresh-rate monitors.

Questions about this item

How do I install the DUAL-RTX4070-12G in a small chassis with the 2.55 slot design?

Align the PCI Express 4.0 edge connector, press firmly until the retention latch clicks, then secure the two rear brackets; the 2.55 slot thickness leaves room for adjacent cables in compact cases.

When will the dual ball fan bearings need replacement?

Dual ball bearings last up to twice as long as sleeve designs; under typical gaming loads they run for years before any bearing noise appears.

What thermal limit appears first during sustained 4K loads?

The 12GB GDDR6X memory at 21 Gbps hits its temperature target before the GPU core, triggering fan ramp-up via 0dB technology.
