Description
The SilverStone Air Slimmer 90 (SST-AS90B) redefines cooling efficiency for space-constrained environments. Measuring just 15.2mm thick, this 92mm fan utilizes a high-pressure blade design and a wide PWM range of 500 to 2,500 RPM. It balances silent operation at low loads with a powerful 45.73 CFM airflow when temperatures rise, ensuring that even the tightest Mini-ITX enclosures remain cool under heavy workloads.
This product is for:
- SFF Enthusiasts: Ideal for Mini-ITX builds like the Velka or FormD T1 where standard 25mm fans cannot fit.
- HTPC Builders: Perfect for low-profile Home Theater PCs requiring quiet operation and slim dimensions.
- GPU Modders: A great choice for "deshrouding" graphics cards to replace stock fans with higher-quality PWM alternatives.
- Server Technicians: Suitable for 1U or 2U rackmount chassis where vertical clearance is strictly limited.
- Workstation Users: Provides reliable, long-term cooling for compact professional workstations using hydraulic bearing technology.
Detailed specifications:

- Static Pressure: 0.11 ~ 2.29 mmH2O
- Noise Level: 11.3 ~ 32 dBA
- Bearing Type: Long-life Hydraulic Bearing
- Material: Polycarbonate fan blades with a PBT frame
- Power: 12V DC, 0.32A, 3.84W
Integrating the Air Slimmer 90 into a build is straightforward thanks to its 300mm fixed cable and integrated rubber padding. These pads effectively decouple the fan from the chassis or heatsink, eliminating resonance and vibration noise. During operation, the hydraulic bearing ensures a smooth acoustic profile, while the high static pressure of 2.29 mmH2O makes it surprisingly effective when pushed against dense radiator fins or restrictive mesh panels.
Compared to standard 92mm x 25mm fans, the SST-AS90B saves nearly 10mm of clearance, which is often the difference between a closed side panel and a compatibility conflict. While it maintains a higher RPM ceiling than the Noctua NF-A9x14, it offers a competitive balance of airflow-to-thickness, making it a more aggressive cooling solution for high-TDP components in sub-10L cases.
Q&A:
- Will this fan fit on a standard 92mm CPU cooler? Yes, as long as the cooler uses standard 92mm mounting holes, though you may need shorter fan clips or zip ties due to the 15.2mm thickness.
- Does it support 0 RPM mode? The fan operates down to 500 RPM; check your motherboard's BIOS settings to see if it supports a complete stop via PWM curves.
- Is the cable long enough for large cases? The 300mm cable is optimized for small form factor builds to reduce clutter, but standard PWM extensions can be used for larger mid-tower setups.
- Can I use this for liquid cooling radiators? Yes, its high static pressure of 2.29 mmH2O is specifically designed to overcome the resistance of radiator fins.
- What is the lifespan of the hydraulic bearing? Hydraulic bearings are rated for significantly longer lifespans than sleeve bearings, typically exceeding 40,000 hours of continuous use.
