Hellhound: A Cool but Powerful Beast
The PowerColor Hellhound Radeon™ RX 6600 is built based on AMD’s latest RDNA2 architecture with enhanced performance and cooling efficiency to empower gamers to vanquish 1080p gaming. Housing two 100mm fans, the shroud is clean and sleekly crafted with silver accent, just like a hound stays calm and low-keyed but always ready to release its power inside.

The Power of Hellhound
To provide a better thermal solution, PowerColor Hellhound Radeon™ RX 6600 is equipped with a dual fan design (2x 100mm), a cooler with 3X6Φ nickel plated heatpipes, and a smooth nickel-plated copper base that enhances heat dissipation. Besides, it adopts 5+1 phase VRM with DrMOS, high polymer solid capacitors and one 8-pin PCI-E connectors to deliver advanced gaming performance.

Overview
(1.Back Plate) The metal back plate strengthens the card and improves the airflow through the cuts. (2.LED Switch) Want to keep a low profile for a while? Just flip the switch; the fan LED will be off. (3.DrMOS) DrMOS provides superior power efficiency and offers better thermal protection. Hellhound is armed with stronger components: a 5+1 phases VRM guarantees better overclocking and stability. (4.Cooler) 3X6Φ heatpipes efficiently dissipate the heat and make your card cool. (5.Dual Fan) The 2x 100mm optimized static pressure fan design provides more air flow and longer circulation. (6.LED Lihting) Hellhound features the blue LED lighting on the shroud and backplate that provides a cold color when lighten up in your case.

Two Ball Bearing - 4X greater longevity
The cooling fan utilizes two-ball bearing technology, increasing the longevity of the fans by up to 4 times.

Mute Fan Technology - 0db –Silent gaming
Mute Fan Technology intelligently turns off the fan below 60℃, providing silent gaming during medium and low load while reducing power consumption.

Exclusive New Cooling-Fan Design, Advanced Cooling Solution
Compared with previous designs, PowerColor Hellhound RX 6600 graphics card uses an exclusive new cooling-fan design to increase airflow and air pressure by up to 60%, achieving new levels of thermal performance.
Dual-Fan Cooler, Lower Temperature Better Performance
The Hellhound Radeon™ RX 6600 is equipped with 3X6Φ nickel plated copper heatpipes and an enlarged heatsink surface for providing lower temperatures and better performance.

Horizontal Aluminum Fin Design
The increased array of horizontal aluminum fins helps heatpipes collect and dissipate heat with maximum efficiency, specifically suited for Radeon™ RX 6600.

Stunning Hellhound Brighten in the Dark
Hellhound features blue LED lighting on the shroud and backplate to lighten up your case. Want to keep a low profile for a while? Just flip the switch to turn the fan LED off.

Reinforced Back Plate
The metal back plate is extremely rigid to strengthen the card and prevent PCB bending, while the hollow area on it improves airflow.
