Noctua OC Edition RTX 3070

This ASUS GeForce RTX 3070 pairs NVIDIA Ampere architecture with two Noctua NF-A12x25 PWM fans and a custom heatsink. It targets builders who want low-noise thermal performance in a 4.3-slot design. The card carries 8GB of GDDR6 memory across a 256-bit bus and a 220W TDP.

LHR model replaces standard RTX 3070

The Lite Hash Rate variant caps Ethereum mining at roughly 25 MH/s while keeping gaming clocks intact. OC mode lifts the boost clock to 1845 MHz and Gaming mode runs at 1815 MHz. The jump makes sense when quieter operation matters more than raw hash rate.

Dual BIOS and 12.20-inch length

A hardware switch toggles between Quiet and Performance BIOS profiles without software. Two 8-pin connectors feed a 750W recommended PSU. The 310mm length demands a spacious case; the 4.3-slot thickness can block adjacent PCIe slots on tighter motherboards.

Questions about this item

Will the 310 mm length and 4.3-slot width fit in my case and motherboard spacing?

The card measures 310 mm long and occupies 4.3 slots, so verify your case clearance and that adjacent PCIe slots remain unobstructed.

Which PCIe power cables are required for the 220 W board?

Connect two 8-pin PCIe cables from a 750 W or larger PSU; using a single daisy-chained cable can cause instability.

When should I clean the two Noctua NF-A12x25 PWM fans and heatsink?

Remove dust from the fans and tailor-made heatsink every 6 to 12 months to maintain the low-noise cooling performance.
