Segment LCD monitoring

The darkFlash DO360 is a 360mm all-in-one liquid CPU cooler with a built-in segment LCD screen that shows real-time processor temperature. A copper cold plate and three 120mm PWM ARGB fans are pre-installed on a 394×120×27mm aluminium radiator. The unit targets gamers and builders who want visible thermal data and addressable lighting in a white finish. It fits Intel LGA 115x, 1200, 1700 and 1851 sockets plus AMD AM4 and AM5 platforms.

Upgrade from air or smaller AIO

The cooler is rated for 315W TDP, driven by a 3000 RPM three-phase pump and fans that run between 800 and 2100 RPM. That combination delivers up to 68.76 CFM airflow and 2.49mm H₂O static pressure while keeping noise at 36 dBA. The jump is worth it when a high-end CPU sustains heavy loads that push lesser coolers past their thermal limits. Hydraulic bearings on both pump and fans are rated for 40000 hours of operation.

5V ARGB sync and tubing constraints

Lighting uses a 5V addressable header compatible with ASUS Aura Sync, MSI Mystic Light, Gigabyte RGB Fusion and ASRock Polychrome. Braided IIR+EPDM tubing is fixed in length, so case clearance must accommodate the 394mm radiator plus 28mm fan thickness. The pump block measures 70.6×70.6×56.5mm and adds a half-mirror, half-matte cover that may interfere with tall memory modules in tight layouts.

Questions about this item

How much clearance does the 394 mm radiator need for a top or front mount?

The radiator measures 394 mm long, 120 mm wide and 27 mm thick, so allow at least 394 mm of straight run plus the 28 mm fan depth on the intake side.

Which step do builders often miss when fitting the Intel LGA 1700 or AMD AM5 mounting brackets?

Many forget to swap the back-plate standoffs for the correct socket — use the LGA 1700/1851 posts for Intel and the AM5/AM4 posts for AMD before tightening the cold-plate thumbscrews.

When should the pre-applied thermal paste be replaced on the copper cold plate?

Replace the paste whenever the block is removed or after roughly two to three years, cleaning the 70.6 mm square copper surface with isopropyl alcohol before applying a fresh pea-sized dot.
