Thermalright HR-01 "High-Riser"

Its 50$ at heatsinkfactory...good buy eh?
Thermalright's HR-01 is an excellent heatsink when used with a 120 mm fan placed directly on its fins. Users mounting this heatsink in a fanless mode will experience performance dependent upon airflow though the case and air temps at the heatsink. Frankly, considering its excellent performance with a fan, I would opt for a quiet 120 mm fan rather than fanless operation.
