The results of our cooling efficiency tests are given on the following diagram and in the following table:
This was a really intense battle. SilverStone Heligon HE01 did a great job withstanding the force of Phanteks PH-TC14PE and yielded only 1°C at the maximum fan speed and 1-2°C when tested with alternative Phanteks fans. The big and thick 140 mm SilverStone fan helped Heligon HE01 maintain such superb cooling efficiency that in 1200-1600 RPM range the temperatures of the hottest processor core are identical. Only at 1000 RPM the temperature increases by 3°C, and when the rotation speed drops to 800 RPM – by another 4°C. Note that Heligon HE01 heatsink responded very well to the use of two Phanteks fans. For example, the cooling efficiency of the Heligon HE01 at 1000 RPM of the Phanteks fans was identical to its cooling efficiency at 1600 RPM of the default fan. And at the maximum 1280 RPM speed of the Phanteks fans SilverStone cooler demonstrated only 1°C lower result than with the default 140x38 mm fan at its maximum speed.
Obviously we can’t unveil the coolers potential fully at 4.375 GHz CPU clock frequency and 1.385 V Vcore, that is why we overclocked our test CPU even more – to 4.5 GHz at 1.42 V Vcore. Although SilverStone Heligon HE01 didn’t cope with this aggressive overclocking at 800 RPM speed of the default fan as well as two Phanteks fans. Therefore, you won’t find these results on the diagram:
And again the race is really neck and neck. Even though the flagship Phanteks PH-TC14PE cooler kept its leadership in this competition, the results of SilverStone Heligon HE01 deserve our absolute respect. This is a truly outstanding product!
You can compare the results of our today’s testing participants against the previously tested products in the following table and diagram*. Each cooler was tested in its default configuration in the quiet mode and at the maximum speed of the fan(s) with the CPU overclocked to 4.375 MHz at 1.385 V Vcore.
As we can see, at the maximum fan speed SilverStone Heligon HE01 ranks among the best air coolers falling as little as 2°C behind only three other products. The results obtained in quiet mode at 800 RPM are also very impressive, because it outperformed over a dozen very popular coolers. However, being so close to the 40-dollar Thermalright TRUE Spirit 140 makes the investment in SilverStone Heligon HE01 for use in quiet mode quite questionable.
As for the summary diagram with the maximum CPU overclocking results, here SilverStone Heligon HE01 ranks as one of the super-heavyweights, even though it failed to conquer the maximum frequency of our test processor (4.625 GHz at 1.46 V):
