During our tests we used a 120 millimeter fan from Noctua which when driven at 12 Volt produces a noise level that is audible. Using an adapter and regulating the voltage to 7 Volt made the noise level drop to subjectively silent. At 12 Volt and 1400 rotations per minute we measure 85°C core temperature. In our opinion this is ok also for long term use. Driving the fan at 7 Volt and 800 rotations per minute made the core temperatures increase to 96 °C which really is too much for long term use. Never the less this isn't a bad cooler and we also have to mention that we do not have any other low profile coolers in our comparison. This puts things into perspective and we think this is a capable cooler for HTPCs and small form factor desktops.

If you're looking for a capable cooler for you HTPC build or a small form factor desktop PC, then the Samuel 17 from Prolimatech is a good choice. These days you can get this cooler for CHF 49.- (est. EUR 41.-)
