Dual-tower cooler for overclocked CPUs

The Dark Rock Pro 5 is a dual-tower air cooler rated for 270 W TDP. Seven copper heat pipes and a ceramic-particle black coating move heat away from Intel LGA 1700, LGA 1851 and AMD AM5 sockets. Two Silent Wings PWM fans, 135 mm and 120 mm, deliver 50-55 CFM and 65-70 CFM respectively at 1300-2000 RPM. Addressable RGB lighting adds subtle illumination without compromising the all-black aesthetic.

Upgrade from single-tower or stock coolers

Builders moving from a 120 mm single-tower design or an included box cooler gain the headroom needed for sustained all-core loads and moderate overclocking. The 168 mm height fits most mid-tower cases, while the offset front fan and cut-outs clear tall memory modules and VRM heatsinks. A detachable top cover simplifies installation and fan access. Liquid-metal thermal paste compatibility is validated for enthusiasts seeking maximum conductivity.

Steady output under prolonged load

In Performance Mode the fans spin to 2000 RPM, maintaining airflow during hour-long compiles or rendering sessions. Quiet Mode caps speed lower, keeping noise near 25.8 dB(A) while still dissipating significant heat. Fluid-dynamic bearings and six-pole motors sustain consistent RPM without rattling. The 4-pin PWM connector lets the motherboard adjust curves in real time, so temperatures stay stable whether the workload lasts minutes or days.

Questions about this item

Will the 168 mm height of the Dark Rock Pro 5 fit inside my case?

The cooler stands 168 mm tall, so your case must allow at least that much CPU-cooler clearance.

How do I install the front 135 mm fan without blocking my RAM slots?

Slide the height-adjustable front fan up on its rails until the 135 mm frame clears your tallest memory module, then tighten the thumbscrews.

When should I replace the two Silent Wings fans on this cooler?

The fluid-dynamic bearings are rated for long life; plan to swap fans only if noise rises above the 20 dBA spec or airflow drops below 50 CFM.
