Reducing vibration at the mounting point is the clear purpose of this Noctua accessory kit. Rather than being a case fan itself, the NA-SAV4 provides 16 tool-free silicone rubber mounts for installing up to four fans with a flush finish. Its damping material is designed to reduce structure-borne noise that can travel from a running fan into the case panel or chassis. Fan size, bearing type, airflow, and noise-level figures are not listed because no fans are included. It is a practical choice for builders who want a cleaner installation than conventional fan screws while addressing vibration-related noise.

Reducing vibration at the fan-to-case contact point is the purpose of Noctua’s NA-SAV2 chromax.Black mounting kit. Rather than a fan itself, it supplies 20 double-sided silicone rubber mounts, enough to install up to five compatible fans without tools. The flexible mounts are designed to dampen structure-borne noise that can travel from a running fan into the case panel. Its all-black chromax.Black finish suits darker builds, while the double-sided design supports fan installation from either side. Fan size, bearing type, airflow, and noise measurements are not listed because this is a mounting accessory, not a complete case fan.

Pros & Cons

Helps isolate fan vibration from the PC case
Includes enough mounts for up to five fans
Tool-free installation design
All-black appearance suits understated builds

This is a mounting kit, not a complete fan

ARCTIC P12 120mm 5-Pack Fans

Size P12 Series

Product Group Personal Computer

Shop on Amazon VIEW MORE

Building out several fan mounts at once is where this five-pack makes the most sense. Each ARCTIC P12 is a 120mm black case fan rated for speeds up to 1800 RPM, with a pressure-optimised design intended for PC cooling setups where airflow has to work through tighter spaces. ARCTIC also highlights a quiet motor, though the listing does not provide a measured noise rating. Bearing type and airflow figures are not listed either, so shoppers comparing exact acoustic or airflow performance will need additional details. It is a straightforward option for users who need multiple matching 120mm fans.

Pros & Cons

Includes five 120mm fans in one pack.
Pressure-optimised design is stated by the manufacturer.
Quiet motor is a listed feature.
1800 RPM speed rating is provided.
Matching black fans support a consistent build appearance.

The listing does not specify bearing type.
No airflow rating is provided for direct performance comparisons.
A measured noise-level figure is not listed.

Which Exhaust Fan Fits Your Build

For a straightforward rear or top exhaust setup, I would prioritize a standard 120mm fan with motherboard speed control and a sensible noise profile. Fan placement matters as much as the model, so make sure the fan arrow points out of the case and that front intake has a clear path to feed it cool air. Noctua publishes useful specifications for comparing its fan lineup.

If you want a dependable Noctua exhaust fan that can also work on a radiator or CPU cooler, I would go with the Noctua NF-P12 redux-1700. Its pressure-optimized blade design, PWM control, and maximum 1700 RPM give it flexibility for filtered case vents and more restrictive mounting locations.
For an all-black build where vibration reduction is the priority, I would add the Noctua NA-SAV2 chromax.Black mounts to compatible open-frame fans. The soft silicone mounts decouple the fan from the case, which can reduce structure-borne noise.
If you need several fans for a larger chassis, I would consider the ARCTIC P12 pack. Its pressure-focused design and fluid dynamic bearing make it a practical alternative when filling multiple mounts, while our 120mm CPU fan roundup covers cooler-focused options too.

FAQs

Q: Should a case exhaust fan use PWM control?

A: PWM gives a compatible motherboard the ability to adjust fan speed as temperatures change. It is useful for an exhaust position because the system can stay quieter during light work and increase airflow during gaming or heavier CPU and GPU loads. The Noctua fan listed here supports four-pin PWM control.

Q: Where should I install an exhaust fan in a PC case?

A: The rear mount near the CPU socket is usually the first exhaust location to fill, since warm air naturally collects in that area. Top-mounted exhaust fans can help in cases with suitable vents. Leave enough intake capacity at the front or bottom so exhaust fans are not pulling against a restricted airflow path.

Q: Do anti-vibration mounts make case fans quieter?

A: They can help when vibration transfers from the fan frame into a metal or glass-adjacent case panel. Silicone mounts isolate the fan from the chassis better than rigid screws in many installations. They do not change blade noise, but they can reduce unwanted hum or rattling from the mounting point.

Q: Is a pressure-optimized fan useful for case exhaust?

A: Yes, especially when the exhaust location has a dust filter, grille, radiator, or tight vent pattern that resists airflow. Pressure-oriented fans are designed to push through resistance more effectively. For liquid-cooled systems, see our best 360mm AIO liquid CPU coolers for compatible cooling approaches.

Editor’s Verdict

For the best Noctua fans for case exhaust, I would choose the Noctua NF-P12 redux-1700 for its PWM control and pressure-focused design. Add the Noctua NA-SAV2 chromax.Black mounts when compatible fan frames need extra isolation from case vibration.
