Zalman CNPS20X Review

Zalman CNPS20X flagship dual-tower air cooler, 8 nickel-plated heatpipes, dual 140mm ARGB fans, 165mm height, 250W TDP, AM4/AM5/LGA1700 support.

CNPS20X is Zalman's return to flagship air cooling after years focused on budget parts, eight heatpipes across a wide dual-tower fin stack and a pair of 140mm ARGB fans put it squarely against the dual-tower flagships from bigger brands, with Zalman leaning on aggressive pricing to compete rather than raw brand recognition.

Comparison to Alternatives

Against the Noctua NH-D15 chromax.black, CNPS20X undercuts it substantially on price while adding ARGB the D15 doesn't offer, though it can't match Noctua's mounting refinement or six-year warranty. Compared to the Thermaltake TOUGHAIR 510 in this catalog, both chase a flagship-adjacent RGB dual-tower look, with CNPS20X's extra heatpipes giving it a thermal edge.
