The Cooler Master Hyper 612 PWM is a very large CPU cooler. Adding a second fan, while decreasing your temperatures, will make the cooler much larger and may even cause some clearance issues. Due to its large size, this cooler might not be right for everyone, especially those with a smaller case. Despite its large size, it does provide some decent cooling. While it’s not the best we’ve tested, it’s also not the worst. We got a really nice idle temperature of 29°C, which might be the seller for some, but the load temperatures just weren’t that impressive.
Word of mouth indicates this cooler is going to sell for around $50, which wouldn’t be a bad price to pay for a cooler of this size and cooling performance. This would make a great addition to a larger mid tower or even full tower case, but can cause some installation and clearance issues with smaller cases. Think Computers would like to award the Cooler Master Hyper 612 PWM an 8 out of 10 score.
