ARCTIC Alpine 17 CO CPU Air Cooler – Compact 92mm Cooler for Intel LGA1700 & LGA1851

The ARCTIC Alpine 17 CO (SKU: ACALP00041A) is a compact, low-profile CPU air cooler built specifically for Intel platforms. It is exclusively compatible with Socket LGA1700 and LGA1851, making it a focused solution for systems running Intel Core i3, i5, i7, i9, and Intel Core Ultra 5, 7, and 9 processors. At the heart of the Alpine 17 CO is a 92 mm PWM-controlled fan with a wide speed range of 250 to 2700 RPM. This wide operating band allows the cooler to run near-silently at light loads — measuring just 0.5 Sone at full speed — while ramping up when your CPU demands more cooling headroom. The fan draws only 0.09 A and connects via a standard 4-pin PWM header, giving your motherboard full control over fan speed without any additional software. The heatsink is crafted from aluminum and uses an innovative Y-shaped fin arrangement that fans out the cooling surface in a radial pattern. This design increases the effective surface area and optimises airflow through the fins, improving heat dissipation within a footprint of just 95 × 95 × 77 mm (installation height: 66.25 mm) and a total weight of 288 g. The compact dimensions are particularly suited to small form factor and mini-ITX builds where tower coolers are impractical. A key differentiator of the Alpine 17 CO is its dual ball bearing fan motor. Compared to sleeve or plain bearings, ball bearings tolerate higher ambient temperatures and are significantly less susceptible to contamination — qualities that translate directly into reliable 24/7 continuous operation without performance degradation over time. Installation requires no additional tools. Push-pin mounting clips allow the cooler to be seated securely on the socket, and ARCTIC's MX-4 thermal compound comes pre-applied to the base, so you can mount and run immediately without sourcing paste separately. ARCTIC backs the Alpine 17 CO with a 6-year manufacturer's warranty, reflecting the confidence built through long-term durability testing under varied operating conditions.
