What owners and reviewers say
Summarised from 1 source(s), reviewed September 13, 2026. A source is counted only where it names this model exactly. How we track prices
Commonly praised
- The best performer among the low-profile coolers tested, and very quiet at full speed.
- Strong value given its price and bundled accessories, improving on the older model with better clearance.
Commonly criticised
- Its low profile limits cooling headroom.
- In one mounting orientation the raised I/O cover can hinder installation and block the first memory slot.
