DeepCool Assassin IV (Dual-Tower Air/7 Heatpipes/Dual 140mm FK140 Fans/270W TDP/Flagship) Review
The DeepCool Assassin IV is DeepCool's flagship dual-tower air cooler, using seven heatpipes and two large 140mm FK140 fans to push its TDP ceiling to roughly 270W, putting it in direct contention with Noctua's NH-D15 lineup and be quiet!'s Dark Rock Pro 6 at a meaningfully lower price.
The DeepCool Assassin IV is DeepCool's flagship dual-tower air cooler, using seven heatpipes and two large 140mm FK140 fans to push its TDP ceiling to roughly 270W, putting it in direct contention with Noctua's NH-D15 lineup and be quiet!'s Dark Rock Pro 6 at a meaningfully lower price.
Thermal Performance
Seven copper heatpipes and a wide dual-tower stack handle roughly 270W of TDP, placing the Assassin IV among the strongest air coolers available and closing much of the gap to premium Noctua and be quiet! flagships.
Fan Design and Noise
Two 140mm FK140 PWM fans deliver strong airflow through the dense fin stack, running a bit louder under full load than Noctua's NF-A15 fans but at a notably lower total package price.
Comparison to Alternatives
Against the Noctua NH-D15 chromax.black, covered elsewhere on this site, the Noctua wins on acoustics and long-term fan reliability, while the Assassin IV comes close on raw thermal ceiling for considerably less money. Against the be quiet! Dark Rock Pro 6, also covered elsewhere on this site, the Dark Rock Pro 6 adds a semi-passive quiet mode this DeepCool lacks, while the Assassin IV undercuts it substantially on price.

Expert Review
Reviewed by Burooj Alam. Rated by us, not by users.
Expert rating8.7 / 10
A genuine flagship-tier challenger that gets DeepCool most of the way to Noctua-level cooling for a fraction of the price.
Best for
- Buyers who want flagship-tier air cooling without paying Noctua or be quiet! flagship prices.
- Heavy overclocking or workstation builds needing roughly 270W of TDP headroom.
- Buyers comfortable trading a little acoustic refinement for a meaningfully lower price.
Not for
- Not for buyers who want the quietest possible operation, where the be quiet! Dark Rock Pro 6, covered elsewhere on this site, leads.
- Not for the smallest cases, given the large dual-140mm-fan footprint.
- Not for buyers who specifically want Noctua's fan reliability track record, where the NH-D15 chromax.black, covered elsewhere on this site, is the safer long-term bet.
