This article covers Thermalright Peerless Assassin 90 SE ブラック CPUエアクーラー デュアルタワークーラー 110mm 高CPU冷却ファン コンピューターラジエーター AMD:AM4.

Overview

The Thermalright Peerless Assassin 90 SE Black is a compact dual-tower CPU cooler standing just 110mm tall. It features a single 92mm fan, four AGHP heat pipes, and a copper base for efficient heat dissipation. Designed for small form factor builds and space-constrained cases, it delivers impressive cooling without sacrificing compatibility.
This cooler supports Intel LGA1851/1700/1200/115X and AMD AM4/AM5 sockets, covering the latest mainstream platforms. The black anti-oxidation coating on the top plate and aluminum fins gives it a sleek, unified look.
Positioned as a mid-range air cooler, the Peerless Assassin 90 SE strikes a fine balance between cooling performance and compact dimensions, making it a popular choice among builders who need strong cooling in tight spaces.

Compatibility Guide

  • Socket Support: Intel LGA1851 / LGA1700 / LGA1200 / LGA1150 / LGA1151 / LGA1155 / LGA1156, AMD AM4 / AM5. The included mounting kit makes installation straightforward across all supported platforms.
  • Case Clearance: At 110mm height, this cooler fits most mini-tower and compact mid-tower cases. Always verify your case's maximum CPU cooler height before purchase.
  • Memory Interference: The dual-tower design may interfere with tall RAM modules (over 45mm height). Standard-height memory works fine. The fan clips allow slight vertical adjustment to avoid contact.
  • Power Connector: The fan uses a 4-pin PWM header for automatic speed control via the motherboard CPU_FAN header.

Product Info

Released around 2024, the Peerless Assassin 90 SE Black carries a typical street price of around ¥5,000 (subject to fluctuation). Warranty is standard 2 years (confirm with retailer). It handles CPUs up to roughly 200W TDP, with a max fan speed of 2200 RPM, airflow of 32.77 CFM, and noise level of 23.85 dBA.
This cooler targets entry-level to mid-range CPUs (Core i5 / Ryzen 5 class). For high-end chips (Core i9 / Ryzen 9) under sustained heavy loads, a larger air cooler or liquid cooling is recommended.

Best Use Cases

  • Small Form Factor Builders: Ideal for ITX and compact cases where height is limited. The 110mm profile fits many SFF enclosures while still providing dual-tower cooling performance.
  • Silence-Oriented Users: With a noise rating of 23.85 dBA, it remains nearly inaudible at idle and quiet under load thanks to PWM control.
  • Budget Gamers: Sufficient for mid-range CPUs like Ryzen 5 7600 or Core i5-14600K, even with mild overclocking. Great value for the cooling capacity.
  • Who Should Avoid: Users with high-end CPUs (Ryzen 9 7950X, Core i9-14900K) who run all-core workloads, or extreme overclockers. Those users should consider larger air coolers or AIO liquid coolers.

Things to Consider

  • Case Height Limit: While 110mm is compact, some ultra-small cases (e.g., InWin Chopin) may not accommodate it. Always check your case's CPU cooler clearance.
  • RAM Clearance: The dual-tower design can obstruct the first DIMM slot if tall RAM modules are used. The fan can be shifted upward slightly using the included clips, but pre-checking is advised.
  • Competitor Comparison: In the same price range, alternatives like Noctua NH-L9x65 or Cooler Master G200P exist. The Peerless Assassin 90 SE offers better cooling due to its dual-tower design, but is taller than ultra-low-profile coolers.
  • Overkill Potential: For low-power CPUs (e.g., Ryzen 5 5600G), this cooler is overkill. A cheaper single-tower cooler would suffice.

FAQ

Q: Does this cooler support Intel LGA1851?
A: Yes, official support includes LGA1851, making it compatible with Core Ultra 200 series (Arrow Lake) processors.
Q: What RAM height is safe without interference?
A: Standard-height RAM (under 35mm) works without issues. Taller modules like Corsair Dominator Platinum may contact the first fan; you can raise the fan slightly using the provided clips to avoid interference.
Q: Is the included thermal paste good enough?
A: The bundled Thermalright TF4 paste is adequate for initial use. For maximum thermal transfer, especially with overclocking, consider upgrading to a high-performance paste.
