Noctua NA-FK1 Redux Second Fan Upgrade Kit for NH-U12S Redux Cooler
The Noctua NA-FK1 Redux Second Fan Upgrade Kit for NH-U12S Redux Cooler is an accessory that adds a second fan to the Noctua NH-U12S Redux CPU cooler.
It suits anyone who already runs an NH-U12S Redux and wants to add a second fan to the heatsink, which is commonly done to improve airflow through the fins. It is not a cooler on its own. You need the NH-U12S Redux to use it. Browse more Noctua products if you are planning a full cooling setup.

Compatibility and related parts
This kit is made for the NH-U12S Redux, so check that this is the cooler in your system or the one you plan to buy from our air CPU coolers. A second fan on a tower cooler can take up extra room, so check the clearance around your RAM and inside your case. Our PC cases listings help with case choice. If you are building a new system, the PC builder checks compatibility, and parts bought as part of a PC build get free assembly and testing. See the full range of Noctua products for matching parts.
