Backplane heat exchanger for 3090 3080 3070

This aluminium backplate cooler mounts on the rear of GeForce 3090, 3080 and 3070 graphics cards to address high memory temperatures on the 3090. Two 5010 fans push up to 20 CFM through a 15 mm thick radiator while running at 1500 to 5000 RPM. PWM control via a small 4-pin connector allows automatic speed adjustment.

Best for 3090 owners with rear memory modules

Builders using a 3090 benefit most because that model places video memory on the back of the PCB where the radiator makes direct contact. Users of a 3080 or 3070 without rear memory will see little temperature improvement, so they should consider other cooling upgrades.

90 by 180 mm footprint with 400 mm PWM lead

The cooler measures 90 by 180 by 15 mm and includes a 400 mm cable ending in a standard 4-pin PWM header, so the motherboard or fan controller can regulate the dual fans between 1500 and 5000 RPM.

Questions about this item

How hot does the 3090 backplate get before the dual 5010 fans reach their 5000 RPM limit?

The fans spin between 1500 and 5000 RPM with PWM control; actual backplate temperature depends on your card load and case airflow.

What noise and airflow should I expect from the two 5010 fans running all day at full speed?

Each fan delivers 10.3 CFM at up to 27.5 dB, so the pair moves roughly 20 CFM while staying under 30 dB combined.

Which power header do I need on my motherboard or GPU to run the 4-pin PWM fans on this radiator?

A standard 4-pin PWM header; the included cable is 400 mm long.
