Without further ado, here are the test results. The average values are calculated out of all three test runs per fan per configuration.
The Tranquillo shows solid performance at stock speeds in idle as well as under load. The idle temperatures are below 40C degrees, hovering in the 35 degree range and under load does not go beyond 55 degrees. The Gelid factory fan only falls slightly short and is about a degree behind the Gentle Typhoon. The SanAce has the lead and inches out a degree ahead of the Gentle Typhoon.
In the 3.6 GHz configuration the Tranquillo remains in a good temperature area. At idle, the Tranquillo keeps the CPU below 40's. The Tranquillo passes the load test but temperatures rise into the 70's. Only the SanAce can hold it below 70c degrees. The gap opens up here a little bit. The Tranquillo is a degree behind the GT and the SanAce separates from the field by 5 degrees.
With a 4.0 GHz overclock and a VCore of 1.4v on a heavily loaded i7 930, the Tranquillo nears it's limits. The Tranquillo passes all tests with any of the fans we tested. The Tranquillo keeps temperatures below 90C degrees. The Gentle Typhoon can also gain a 3 degree gap on the Silent 12 PWM. The SanAce fan maintains a 5 degree temperature advantage over the Gentle Typhoon.
The temperature remains within or below 20c degrees delta between idle and load.
The delta temp widens to 30 degrees between idle and load while at 3.6 GHz. This is a pretty decent result.
The gap really opens up at 4.0 GHz configuration. Here we can see a 45 - 50 degree gap.
The Tranquillo Rev2 hovers 10-12c degrees effectively over ambient temperature at idle and jumps to 30c degrees at load.
The Tranquillo hovers around 10-15c degrees over ambient at idle and goes up to a 40-45c degree under load.
In the 4.0 GHz configuration, the Tranquillo can remain under 20c degrees over ambient at idle. The load temperature range difference becomes more clear now. The SanAce separates itself from the group rather clearly.
Our throttle tests were all positive, and there were no signs of CPU throttling at all.
The Tranquillo has potential and fares best with the powerful SanAce. This is Gelid's 2nd try on the Tranquillo and there is still headroom when supplied with the right airflow.
