For testing, I decided to test the cooler by using Artic Ceramique instead of the included thermal grease. I placed a layer on the CPU and left the system working in order for the thermal paste to stabilize for about 24 hours. Also, since the cooler features adjustable fan, I took thermal readings at 3 speeds, being low, medium and top speed. CPU load was achieved by running two instances of Prime95 for 30 minutes. The idle temperature measurements were noted after the system was resting at the windows desktop for 30 minutes. Ambient temperature is maintained (as accurately as possible) at 22 degrees Celsius at the time of the test. Cool-&-Quiet is disabled.

As we can see from the above results, the 3310BL is not much of a cooler while running at low speeds, but dramatically improves as the fan speed goes up. We could safely assume that the 80mm fan that this cooler is using may be too small for providing an adequate amount of airflow while running silent. However that does not keep the cooler from being very competitive as the fan speed goes up.
