Thermalright Peerless Assassin 120 Mini White CPU Air Cooler - Dual

In this review the Thermalright Peerless Assassin 120 Mini White is evaluated as a compact dual-tower air cooler aimed at builders who need strong cooling in a small footprint. The bottom line: it offers impressive heat dissipation for its size thanks to six 6mm AGHP heatpipes and a pair of 120mm TL-D12W PWM fans, making it a smart choice for users who want quiet, efficient CPU cooling without a large tower blocking RAM or case airflow.

Key Features

• AGHP 4th gen heatpipes: Six 6x6mm fully plated heatpipes use upgraded AGHP technology to reduce orientation-related performance loss and improve heat transfer.
• Dual tower design: Two compact fin stacks with a CNC micro-engraved copper base increase surface area for faster heat dispersion in constrained cases.
• TL-D12W PWM fans: Includes two 120mm PWM fans with S-FDB bearings and shock-absorbing silicone feet to balance airflow with low noise and reduced vibration.
• Durable finish: Main body is fully blackened with an antioxidant coating, giving corrosion resistance and a consistent mech-style appearance.
• Wide compatibility: Mounting kit supports modern Intel and AMD sockets including LGA1700/1851 and AM4/AM5 for easy cross-platform use.

Who It's For

The Peerless Assassin 120 Mini White is best for desktop builders who need strong CPU cooling but must work inside compact mid-tower or server-style cases where large coolers do not fit. It also suits users who prioritize quieter operation thanks to PWM control and S-FDB bearings and who appreciate a blackened, precision-machined base and fins.

Users who should look elsewhere include extreme overclockers who need the absolute highest thermal headroom from large 140mm or multi-fan radiators, and those who require RGB lighting or an overtly flashy aesthetic, since this model focuses on performance and a subdued mech look rather than showy effects.

Pros & Cons

Pros

• Strong cooling for a compact dual-tower thanks to six plated heatpipes and two 120mm performance fans.
• Low-noise operation with PWM control, S-FDB bearing and silicone feet that reduce vibration.
• Good build quality and corrosion-resistant blackened finish with a CNC precision copper base.
• Broad socket compatibility covering recent Intel and AMD desktop platforms.

Cons

• Installation experiences are mixed for some users, so builders new to aftermarket coolers may need extra time following the instructions.
• Not designed for enthusiasts needing the absolute maximum cooling of large radiators or 140mm-only solutions.

Frequently Asked Questions

Will this cooler fit in compact mid-tower cases?
Yes, the 125 x 110 x 110 mm footprint is designed for smaller enclosures, but always check clearance for RAM and case height before purchase.

Does it support current Intel and AMD sockets?
Yes, the mounting kit covers a wide range including Intel LGA1700/1851 and AMD AM4/AM5 with the appropriate plates provided.

Is the fan noisy under load?
Users report low noise levels thanks to PWM control and S-FDB bearings, although perceived noise will vary with case airflow and fan curve settings.
