Bykski N-ST2080PGF-X GPU water block for ZOTAC RTX 2080 PGF Extreme OC12 diy cooling

Full-coverage GPU block for ZOTAC RTX 2080 PGF

The Bykski N-ST2080PGF-X is a full-coverage water block engineered for the ZOTAC RTX 2080 PGF Extreme OC12 and compatible reference-design models including the RTX 2070 PGF OC and RTX 2080 Super AMP. It directly cools the GPU core, memory and voltage regulator modules using electroplated high-purity copper topped with crystal-clear PMMA. Standard G1/4 thread ports support flexible loop routing.

Upgrade from stock air cooling on supported ZOTAC

This block replaces the factory air cooler on the listed ZOTAC RTX 2080 and 2070 PGF models, moving heat into a custom liquid loop for lower operating temperatures. The jump is worth it when thermal headroom limits overclocks or when acoustic targets demand quieter operation than the stock fans provide. A high-flow internal design allows multiple blocks to run in series without excessive restriction.

Handles core, memory and VRM loads on compatible

The copper cold plate covers all three critical zones, giving headroom for higher sustained boost clocks or reduced voltage at stock speeds. It runs out when the PCB layout deviates from the reference design used for the ZOTAC RTX 2080 PGF Extreme OC12, 2070 PGF OC or 2080 Super AMP models. Builders using non-reference or heavily altered partner cards should verify fitment before purchase.
