Without further ado, here are the test results. The average values are calculated out of all three test runs per fan per configuration.
The H612PWM displays solid temperature results at stock speeds in idle as well as under load. The idle temperatures are below 40C degrees and under load does break into the 50 degree range. The included fan from Cooler Master inches out in front of the Gentle Typhoon. The SanAce has the clear lead.
The H612PWM continues on this solid path throughout the 3.6 GHz configuration and remains in a good temperature area. At idle, the H612PWM keeps the CPU in the low 40′s. The H612PWM also passes the load test, but temperatures rise into the 70′s. Only the SanAce can barely hold it at 70c degrees. This is a very acceptable result and clearly keeps the CPU from thermal throttling.
With a 4.0 GHz overclock and a heavily loaded i7 930, the H612PWM still remains in the green zone. The H612PWM passes all tests with any fan. The H612PWM keeps temperatures comfortably below 90C degrees and only the Gentle Typhoon falls a little behind. The SanAce fan retains a 5 degree temperature advantage over the Factory fan, and hovers in the mid 80′s.
The temperature remains within or below 20c degrees between idle and load.
There is a 30 degree gap between idle and load while at 3.6 GHz. This is a pretty decent result.
The gap opens up at 4.0 GHz configuration. Here we can see a 45 – 50 degree gap.
The Cooler Master H612PWM hovers 10-15c degrees effectively over ambient temperature at idle and jumps to 30c degrees at load.
The H612PWM hovers around 15c degrees over ambient at idle and opens up to a 45c degree difference under load.
In the 4.0 GHz configuration, the H612PWM sits at 20c degrees over ambient at idle. The load temperature range difference becomes more clear now. The SanAce separates itself from the group.
Our throttle tests were all positive, and there were no signs of CPU throttling at all.
It is pretty clear and no surprise that the H612PWM fares best with the SanAce fan. The cooling body of the H612PWM has a lot of potential and headroom when supplied with a lot of CFM worth of airflow.
