# Thermalright Peerless Assassin 120 SE

**CPU Cooler** — DealCoconut researched pick in The Value PC Build
Canonical page: https://www.dealcoconut.com/p/cooler.html

- Current price: $36.99 (MSRP $39.90)
- Known low: $34.00 (typical sale)
- Buy timing: **Good time to buy** — Commodity-stable price. It's $37; don't overthink it.
- Reliability: **5/5** — Nothing to break but two standard fans, both replaceable for $10. An AIO adds a pump and coolant loop — the #1 cooler failure mode — for zero thermal gain at this TDP.
- Price note: auto-checked 2026-07-02

**Why this pick:** The most-reviewed value legend in PC building: dual-tower cooling that matches $80–100 coolers for under $40. The 270K Plus doesn't need liquid cooling at stock.

**What it beat:** $80+ AIO liquid coolers — same temperatures, double the price, and a pump that can fail.

**Cheaper alternative:** This is already the save-money pick.

## Common questions
- Will it fit my case/RAM? — 157mm tall, fits the case below with room to spare; offset design clears standard RAM.
- LGA1851 mounting? — Uses the same mount as LGA1700; included hardware works.
