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.

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.
