Common Applications
The N-MS3090AERO-TC is built for the MSI GeForce RTX 3090 Aero 24G, whose GDDR6X memory is mounted on both faces of the PCB. The front cold plate covers GPU die, front memory and VRM, while an active waterway backplate routes coolant directly over the rear GDDR6X packages so memory junction temperatures track core temperatures instead of climbing into throttle territory. Both the front block and active backplate use electroplated high-purity copper under acrylic, and the integrated loop between them is plumbed internally so the user still only manages one inlet and one outlet at G1/4.
Frequently Asked Questions
Q: What is an active backplate and why does this card need one?
A: An active backplate routes coolant across the rear of the PCB to cool the GDDR6X chips mounted on the back of the RTX 3090 Aero. A passive backplate only spreads heat into a metal plate and cannot keep rear memory in spec under sustained load.
Q: Which cards is this block validated for?
A: MSI GeForce RTX 3090 Aero 24G. Confirm your card matches the Aero reference layout shown in the bykski.us listing before purchase, as other MSI 3090 SKUs (Gaming X Trio, Suprim, Ventus) use different PCBs and need their own blocks.
Q: What are the materials?
A: Electroplated high-purity copper cold plates on both the front block and the active backplate, with acrylic tops. G1/4 threaded inlet and outlet.
Q: Are the two halves connected internally?
A: Yes. The front block and active backplate are linked through the card so the loop only exposes one inlet and one outlet to the user.
Q: Will this work in an aluminum-radiator loop?
A: No. The wetted surfaces are copper. Mixing copper blocks with aluminum radiators causes galvanic corrosion that destroys the aluminum and clogs the loop.
