Excerpt: Zalman has been producing CPU coolers for as long as I can remember. Their typical style has been the all-copper “flower” style heatsinks in various configurations and options. The flower style coolers have their advantages with providing airflow to the VRM’s and MosFETs on your motherboard.
Summary: When it comes to low profile heatsinks for miniPC/HTPC/MiniITX/bookPCs there aren't many options. With an eye towards the under populated low profile cooling segment, Zalman released
the CNPS8900 Extreme; a 60mm tall, 121mm diameter low profile cooler built for compact cooling situations.
Summary: The Zalman CNPS8900 Extreme is a beautiful CPU cooler, with a low profile (2.36 inches or 60 mm) and good cooling performance for this category of cooler. It presented the same cooling performance as the Noctua NH-L12, which we recently tested .
