ARCTIC · 40mm Server Fan Value Pack
ARCTIC S4028-6K — 5-Pack
5 × 40 mm6000 RPM max4.2 mmH2O6-Year Warranty
The ARCTIC S4028-6K 5-Pack (part number ACFAN00273A) contains five black 40 × 40 × 28 mm 4-pin PWM server fans that spin from 250 to 6000 RPM, delivering 7.1 CFM and 4.2 mmH2O for 1U/2U servers, network appliances and compact devices. Dual ball bearings, a 400 mm cable and a 6-year ARCTIC warranty make it a durable replacement for noisy or failed small fans.
Typically in stock with fast delivery across Cyprus.
Compatibility note: 40 × 40 × 28 mm fans with a standard 4-pin PWM (2510) connector — check that your device takes 40 mm fans with 28 mm depth and a 4-pin header (3-pin headers run the fan without PWM control). At high speed these server fans are loud, so they suit rack equipment rather than quiet desktops.
Best For
✓ 1U and 2U servers
✓ Network and storage appliances
✓ Mini-ITX and compact devices
✓ 3D printers and electronics projects
✓ Replacing failed 40 mm fans
✓ Rack-mounted equipment

Five fans with 20 mounting screws — enough to re-fan a server chassis or keep spares on hand.

Frequently Asked Questions
Singular Expert Insight
The S4028-6K is a practical way to refresh small, high-pressure fans in rack gear at a lower cost per fan than single packs. For desktop cases, larger fans move far more air at a fraction of the noise — see our case fans range.
Buyer's Guide
Buy it if
You need several 40 mm PWM fans with 6000 RPM and 4.2 mmH2O for servers or appliances.
Skip it if
Your device uses a proprietary fan connector or a different depth (e.g. 20 mm), or you need a quiet fan.
