| SFF-optimized dimensions | Carefully engineered height and footprint to avoid interference with memory modules and GPU brackets in small form factor builds |
❓ Why Choose Our 90mm CPU Air Coolers (FAQ)
🚀 Outstanding Heat Dissipation Performance
Don't let the small size fool you — our 90mm coolers deliver thermal performance that rivals many 120mm models, thanks to optimized fin design and direct-touch heat pipe technology.
• High-performance design: 90mm optimized air duct + pure copper heat pipe, with TDP ranging from 35W to 180W, capable of easily handling mainstream CPU loads.
• Low temperature difference performance: Compared with competitors, the core temperature is on average 3-5℃ lower, extending the lifespan of the hardware.
🤫 Ultra-Quiet Operation
Perfect for quiet office and living environments, our 90mm coolers operate at near-ambient noise levels at idle, staying unobtrusive even under load.
• 23dBA low-noise operation: Self-developed hydraulic bearing fan, with operating noise close to ambient noise.
• Triple shock absorption structure: Eliminates resonance noise, and has passed a 20,000-hour durability test.
🛡️ Military-Grade Quality Control
Every 90mm cooler undergoes rigorous testing to ensure reliable performance even in the most demanding compact builds.
• Full-process ISO9001 control, with defect rate less than 0.3%, and we offer industry-leading 3-year warranty.
🌍 Global Supply Chain Assurance
From small trial batches to large-scale production runs, we deliver on time with transparent scheduling and flexible shipping options.
• From the 1K trial production to the 100K-level orders, the entire process is subject to transparent scheduling, and multiple modes of delivery (land transportation and air transportation) are supported.
📏 SFF & ITX Expertise
Unlike generic cooler manufacturers, we specialize in compact form factor cooling. Our engineering team knows every millimeter matters in ITX and SFF builds.
• Zero interference design: Tested with all major memory brands (including tall heat spreaders) and GPU configurations.
• Clearance-optimized: Multiple height options available to match your case specifications.
• Tool-free mounting: Backplate design enables quick and secure installation even in tight spaces.
