Alphacool Core 2 LT 240mm CPU AiO Cooler (14621)

The Alphacool Core 2 LT 240mm CPU AiO Cooler is a compact AIO liquid cooler with a 240 mm radiator for AMD AM4 and AM5 and Intel LGA 115x, 1200, 1700, 1851 and 2066. As the successor to the Eisbaer LT it is designed specifically for small form factor systems and builds with limited installation space, with a radiator measuring just 25.5 mm thick. The same cooler comes with a 360 mm radiator.

Properties

• Intel sockets: LGA 1150, 1151, 1155, 1156, 1200, 1700, 1851, 2066
• AMD sockets: AM4, AM5
• Radiator: 240 mm, NexXxoS ST25 full copper, 25.5 mm thick
• Fans in the box: 2 x Core 120mm PWM, up to 2,500 RPM
• Pump: Core DC-LT 3 PWM, up to approximately 3,800 RPM
• Tubes: 320 mm TPV, rotatable 90° fittings at the CPU block

Fit

Socket compatibility comes from the CPU mounting hardware in the box, which covers every socket named above. For Intel, the accessories list in the manual shows one set of brackets, a CPU backplate, four mounting parts marked LGA 115x, 1200, 1700, 1851 and four LGA 2066 screws. For AMD it shows one set of brackets and four bolts for AM4 and AM5. Pressure springs and washers in two thicknesses complete the set.

On an AMD board the manual has you remove the two-piece retention frame first. On either platform you clean the CPU, apply the thermal grease and remove the protective film before the cooler goes on. The package includes the thermal paste (1g) and a putty tool.

Successor to the Eisbaer LT

The Core 2 LT combines the proven full-copper radiator technology of Alphacool with an upgraded PWM pump, high-performance fans and a streamlined CPU block. Together they deliver effective cooling in a remarkably compact package. For users looking to add liquid cooling to a compact PC system, that gives an excellent balance of cooling performance, installation flexibility and value.
