Silent Passive Cooling for Low-Power Intel CPUs

The ARCTIC Alpine 11 Passive is a fanless CPU cooler designed for Intel processors with a thermal design power of up to 47 watts. It targets builders who want a completely silent system without moving parts. The cooler suits office PCs, media centres or embedded boxes where noise must be zero. Buyers who need to cool processors above 47 watts or AMD platforms cannot use this model.

Fanless Build Means Zero Dust and No Maintenance

Measuring 95 by 95 by 69 millimetres and weighing 508 grams, the aluminium heatsink mounts directly onto Intel sockets using the supplied push-pin brackets. Because there is no fan, the assembly produces 0 sone of noise and never draws dust into the fins. Pre-applied MX-2 thermal compound allows a quick, clean installation without extra paste. The passive design eliminates bearing wear and the need for periodic cleaning.

47-Watt Cooling Capacity Decides Compatibility

The single specification that determines fit is the rated cooling capacity of 47 watts. Only Intel CPUs operating at or below this thermal envelope will stay within safe temperatures. Systems requiring higher heat dissipation or overclocking headroom must choose an active cooler instead.

Questions about this item

What TDP limit does the passive Alpine 11 design cap at in practice?

The cooler is rated for up to 47 Watts of cooling capacity, which sets the practical thermal ceiling for the CPU it can handle without active airflow.

What physical clearance does the 95 x 95 x 69 mm Alpine 11 need to fit inside a case?

It requires at least 69 mm of height above the socket and a 95 mm square footprint around the mounting holes, so check your case and motherboard layout for that space.

How is the Alpine 11 installed, and what step do builders often miss?

Mount it using the Intel push-pin brackets supplied, then press firmly to spread the pre-applied MX-2 compound — skipping that firm seating is the common mistake that leaves poor contact.
