Digital Display Air Cooler

The GAMDIAS Boreas M2-51D V2 is a single-tower air cooler with a built-in digital display that shows real-time CPU temperature and fan speed. It targets builders who want at-a-glance monitoring without relying on software overlays. The cooler fits mainstream Intel and AMD sockets including LGA 1700, LGA 1851, AM4 and AM5. It is not for compact builds that cannot accommodate a 158 mm tall cooler.

5 Copper Heat Pipes 80.83 CFM

Five copper heat pipes make direct contact with the CPU through a thick base plate, feeding a 120 mm hydraulic-bearing PWM fan that spins between 800 and 2000 RPM. The fan delivers 80.83 CFM at 2.8 mmH2O static pressure while keeping noise between 10 and 32 dBA. This capacity handles mid-range workloads and moderate overclocks; sustained heavy all-core loads on high-TDP chips will push the cooler to its thermal limit.

Open-Box Unit Vertical Fan Mount

The unit arrives in open-box condition with pre-applied thermal grease included. A vertical fan-mounting orientation keeps the heatsink profile narrow for motherboard clearance, while the 9-pin USB connection powers the digital monitor and enables ZEUS CAST software control. The matte black finish and absence of LEDs suit understated builds. Buyers who need RGB lighting or a dual-fan configuration should look elsewhere.

Questions about this item

Will the 158 mm tall heatsink clear the tall RAM modules on my LGA 1700 board?

The cooler stands 158 mm high, so measure from your motherboard surface to the side-panel window; if that gap exceeds 158 mm the RAM height will not interfere.

How do I verify the digital display is showing live CPU temperature and fan RPM after I plug in the 9-pin USB cable?

Connect the 9-pin USB header, install ZEUS CAST software, and the on-cooler screen will mirror the CPU temperature and the 800-2000 RPM fan speed in real time.

Does the package include mounting brackets for AM5 and LGA 1851, or must I order them separately?

Universal mounting kits for AM5 and LGA 1851 are supplied in the box along with thermal grease; no extra bracket purchase is required.
