Without further ado, here are the test results. The average values are calculated out of all three test runs per fan per configuration.
The Xigmatek GAIA shows good load and idle temperature results at stock speeds. The idle is clearly below 40C degrees and under load breaks into the 50′s.
The GAIA continues to remain in a good temperature area at our medium OC @ 3.6 GHz. At idle, the GAIA can keep the CPU in the low 40′s. The GAIA also passes the load test, but temperatures rise into the 70′s. Only the SanAce can barely hold it below 70c degrees. This is a very acceptable result and it keeps the CPU from thermal throttling.
With a 4.0 GHz overclock and a heavily loaded i7 930, the GAIA is struggling a bit to beat the heat. All fans pass the test though. The GAIA can keep temperatures comfortably below 100C degrees. The SA fan can even retain a 4 degree temperature advantage, and hovers in the mid 80′s. This cooler supports a 2nd fan and we believe that the cooling performance could be further enhanced with the use of one.
The temperature remains within 20c degrees between idle and load.
There is a 30 degree gap between idle and load while at 3.6 GHz. This is still a pretty decent result.
The gap opens up at 4.0 GHz configuration. Here we can see a 45 – 50 degree gap. That is quite significant, though it didn’t bump up against the 100C threshold that triggers CPU throttling.
The GAIA hovers 10-15c degrees effectively over ambient temperature at idle but jumps to 30c degrees at load.
The GAIA remains below 20c degrees over ambient at idle, but there is a noticeable rise under load.
At the 4.0 GHz configuration, the GAIA breaks even at 20c degrees over ambient at idle.
Our throttle tests were all positive, and there were no signs of CPU throttling at all. Given the temperatures observed, this was to be expected.
It is pretty clear and no surprise that the GAIA fairs best with the SanAce fan. The cooling body of the GAIA has room to grow but nears its single-fan limits during our testing.
