We test and review the Be Quiet! Shadow Rock LP CPU Cooler. The cooler might not be the strongest performer on the block, but it is low profile and intended for small form factors. These small puppies can be used with any motherboard but focus on Micro ATX and Mini ITX. They are small, deadly silent but do pack enough punch to cool even a Core i7 4790K, albeit it’s not an easy job for this one.
