All of the testing is carried out outside of a computer case. As with every test, we use a thin layer of Arctic Silver 5 between the core and the CPU cooler for comparable results. Ambient temperature was 19C throughout.
To test we simply boot the PC up with a freshly installed copy of Windows XP, and measure temperatures using Speedfan. The onboard temperature sensor is disregarded and instead the CPU’s own diode is used.
For idle testing, we simply let the testing rig sit doing absolutely nothing for 30 minutes and take the most representative temperature of the last 10 minutes. The same is used for the load testing, but instead of letting the PC do nothing, OCCT is used to load both cores to 100%.
As this motherboard also has a temperature sensor in the chipset, we will also measure the temperature of that in the same way as the CPU in order to get an idea of how effective the ‘collateral’ cooling is of the kit.
In a new segment, we’ll be testing out-of-the-box performance, which means that we use all of the included components i.e. the heatpaste. This will give you an impression of the packaged heatpaste and whether using a third-party paste (i.e. AC5) is necessary. These results are marked as OTB.
This cooler comes complete with a molex to either 12v or 5v fan headers, meaning that you can run the G-Power in either full power, or 5v reducing the RPM from 1500 (23 dBA) to 700 producing 16 dBA. We’ll test both of these options, and also the direction which you choose to mount the cooler. The design is such that collateral cooling will be noticeable, and as you can mount the cooler either towards the rear ports, and in this case, onto the chipset heatsink, or towards the RAM we’ll also test both of these options.
Ambient temperature is 19C.
The first thing that I noticed was that the cooler isn’t quite what I would call quiet at full powe.. If you have a noise reducing case, such as one of the Antec P series, or an NZXT Hush, you probably won’t be able to hear it. However, if you swap the 12v for 5, then you’ll be treated to what I can only describe as silent. Yup, I can’t even shoe-horn in my favourite phrase to describe it, as it genuinely is silent. Get a passive PSU and GPU, and your system will be well-nigh unnoticeable.
The included heatpaste, while being a mission to spread, is actually pretty good in comparison to Arctic Silver 5, with the AC equipped test only chucking away a degree on the core. For the anal overclocker, this will probably make the use of AC5 an obvious choice, but you aren’t going to see a dramatic difference between the two pastes.
The results of the cooler looks pretty good, and at full speed, its better than the Noctua NH-U12P, but what these results don’t show is the noise produced. At 12v, the fan is quite loud; especially in comparison to the silence of the Noctua. A better comparison is when the cooler is in 5v mode, but unfortunately it doesn’t cool quite so well.
While these results don’t show this cooler as anything particularly stunning; bar the fact that it cools better and quieter than the stock cooler, you have to look at collateral cooling to see the full strength of the G-power.
NOTE: the OTB results are removed, as the collateral cooling doesn’t depend on the heatpaste used.
As you can see, the G-Power 2 Pro is vastly better than the other coolers when at 12v, but loses its lead when switched to 5v in comparison to the IFX-14. That said, the IFX-14 was much louder than the silent 5v G-Power so its more efficient with its collateral cooling.
