Test System and Thermal Results
I would first like to thank ASUS, InWin, Corsair, and Fractal Design for supplying products for me to test with. To see our testing methodology and to find out what goes into making our charts, please refer to our CPU Cooler Testing and Methodology article for that information.
Something that made us scratch our heads a bit were the thermal results. Due to what we saw, we ran our test series three full times just to be sure it wasn't a fluke. Considering this AIO has very little socket pressure, we were taken aback to see the 49.25 degree average with the pump spinning full speed and the fans running with 7.5V.
This is very impressive from a 240mm AIO solution. For our testing, we found the H105 to be more than 30 degrees better than stock cooling, and only the CoolerMaster Glacer 240L and Nepton 280L performed better in our charts at this time, and those are much more serious kits compared to the standard AIO.
Once we set the system to the overclocked profile, allowed the fans to run at 12V, and ran way too many tests, we certainly verified that the result was in no way a fluke for the stock results, as they are reflected with the same efficiency in the overclocked testing. We are now way ahead of the stock cooler with the 68 degree average across all test runs.
Again, the H105 takes on the third slot in a list of ten total liquid cooled offerings, and one of which it beats is a real custom loop. Considering the thin diameter of the tubing and the limitations imposed by power draw, pump size, and running thicker coolant versus water, the level of efficiency they are able to get from the H105 is very impressive at this level, or any level for that matter.
