Thermalright Peerless Assassin 120 Mini Black CPU Air Cooler

Bottom line: The Thermalright Peerless Assassin 120 Mini Black CPU Air Cooler: Just 135mm tall with a 125 x 110mm footprint for tighter case clearance; main trade-off: ships with a single 120mm fan, so push-pull needs a second fan bought separately.

Pros & Cons

Pros

  • ✓ Just 135mm tall with a 125 x 110mm footprint for tighter case clearance
  • ✓ Six 6mm AGHP heatpipes feed two towers of 48 aluminium fins each
  • ✓ Fits AM4/AM5 plus Intel LGA1851/1700/1200/115x/2011/2066
  • ✓ PWM 120mm fan on an S-FDB bearing, rated 1500RPM +/-10%
  • ✓ All-black anti-oxidation coating over a CNC micro-engraved copper base

Cons

  • ✗ Ships with a single 120mm fan, so push-pull needs a second fan bought separately
  • ✗ 1500RPM fan ceiling limits airflow headroom on hot-running CPUs
  • ✗ Mini towers give up some fin area to reach the lower 135mm height
  • ✗ No RGB lighting listed in the specs for builds that want it

SpecPicks Verdict

SpecPicks scored Thermalright Peerless Assassin 120 Mini Black CPU Air Cooler using a rating × review-volume × price-fit model applied to published specs and reviews across the cooling & fans category. Thermalright's cooling & fans lineup sits within the broader category mid-tier; price and specs are the deciding factors over brand loyalty here.

Key Features

  • [AGHP Technology] 6x6mm heatpipes adopt AGHP upgraded 4th generation technology to solve the effect of anti-gravity caused by vertical/horizontal direction, and 6 pure black fully plated heatpipes, which will bring out the heat dissipation to a better level with the help of 12cm performance fans.
  • [Product Specifications] PA120 MINI BLACK; CPU cooling size: 125 (L) x 110 (W) x 135 (H) mm; Cooler material: aluminium. The main body is fully blackened with antioxidant coating + CNC precision micro-engraved copper base, creating a black look with symmetrical mech-type fins.
  • [Thermal Advantage] CPU cooler's strong heat dissipation is created by 6 heatpipes + dual tower + performance fan, dual tower structure for 48 pieces of all-aluminium fins * 2, to a certain extent, increase the cooling area, by the pure copper base to heat transfer to the 6 heatpipes, and then dispersed to the dual tower, and finally by the pc fan will be blown out of the heat dissipation, to achieve the best cooling effect!
  • [Stable output] CPU cooler with high-performance fan with PWM temperature control function, shock-absorbing silicone feet around to reduce fan noise, anti-touch fan blade design to improve safety, and S-FDB bearing is a solution to the fan lifting jitter vibration. The S-FDB bearing solves the problem of fan lifting vibration. It improves the cooling performance to a great extent.
  • [Compatibility] CPU cooler slot support: Intel: LGA1150/1151/1155/1156/1200/1700/1851/2011/2066; AMD: AM4/AM5; for different CPU slot platforms, the cooler's mounting kit provides the appropriate mounting plate or fasteners, can be combined with the installation instructions or follow the tutorials to the machine.
