Details
The Valkyrie Jarn 360 is an all-in-one CPU liquid cooler with a 360 mm aluminum radiator, three Valkyrie V12 A-RGB 120 mm fans and a PWM-controlled pump in a round, addressable RGB pump housing. Valkyrie rates the Jarn 360 for CPUs up to 300 W TDP and builds it for current AMD and Intel desktop sockets. This is the black version.

Rotatable ARGB pump top
The pump top turns through 360°, so the Valkyrie logo sits straight whichever way round you mount the block. The pump housing carries addressable RGB lighting that you control from the A-RGB header of your motherboard.
Market-tested pump
Valkyrie calls the Jarn pump reliable and market-tested and says it is rigorously tested for durability. It runs from 800 to 2,400 rpm (plus or minus 10%) at 12 V and takes its speed signal through a 4-pin PWM connector. The pump unit measures 83 x 78.6 x 58 mm.
V12 fans on a 360 mm radiator
The 379 x 120 x 27 mm aluminum radiator comes with three Valkyrie V12 A-RGB fans. Each fan runs from 800 to 1,850 rpm, moves up to 75 CFM (127.42 m³/h) with a static pressure of 2.23 mmH2O and stays at a maximum of 34 dBA. The fans have 4-pin PWM speed control and their own A-RGB lighting.
Tubing and wiring
The 425 mm FEP tubes are covered by a corrugated braided sleeve. Valkyrie packs a wire kit and hub set: the hub takes SATA power and links the fan and A-RGB cables to one CPU_FAN and one A-RGB header on the motherboard, which helps when the board has few headers. The pump connects to the AIO_PUMP header.
Mounting
The kit carries an Intel backplate with brackets and an AMD bracket set. Valkyrie lists the cooler for Intel LGA 1851, 1700, 1200 and 1151 and for AMD AM5 and AM4; the installation guide also shows the mounting on Intel LGA 2011 and 2066 with the included LGA2011 bolts. Thermal paste is in the box.

Notes
- Valkyrie makes the Jarn in black and white. This listing is the black version.
- Peel the protective sticker off the cold plate before you mount the block; Valkyrie points out that it is critical to cooling performance.
- Use the shorter fan screws to fix the fans to the radiator. The extended screws are not for fixing the fans.
