We measured the noise level of our coolers throughout the entire speed range of their fans, as described in the chapter on testing methodology. Here are the results:
When we assess the level of noise generated by SilverStone Heligon HE01 compared against its today’s rival, we should remember that Phanteks PH-TC14PE is not really a quiet cooler therefore the nominal victory of the new SilverStone product at the same fan rotation speeds doesn’t proclaim it an undefeated winner. It is true, Heligon HE01 is quieter than PH-TC14PE up to 1200 RPM, but is it really quiet? Unfortunately, not. Only up to 650-700 RPM the 140 mm SilverStone Heligon HE01 fan is really quiet, and it remains within the zone of subjective acoustic comfort up to 800 RPM. By the way, SilverStone set the minimum rotation speed for both PWM modes at 500 RPM for a reason: at this speed you won’t hear a thing even if you have the quietest system out there. However, when the CPU utilization is high, when the fans rotate faster than 800-900-1000 RPM, the noise from SilverStone Heligon HE01 starts becoming more distinct, and at even higher speeds it becomes distracting. No everyone will be able to put up with the noise at the maximum fan speed. I have to add that we didn’t detect any vibrations, beating, crackling or any electric sounds during the fan operation. This is a really high-quality product, which currently cannot be purchases separately. Otherwise, it could become a real hit among those overclockers who do not mind the noise.
Our today’s super-heavyweight fight has definitely been a success. It was exciting and unpredictable, and in some cases it was really hard to determine who the winner was. Although the overall results and the maximum conquered processor frequency didn’t let the new SilverStone Heligon HE01 take the best super-cooler title, it did perform great and demonstrated impeccably high level of cooling efficiency, which is currently only attainable for as few as 3-4 other products from the best cooler makers. Moreover, SilverStone cooler boasts more attractive 75-dollar price tag, while the same Phanteks PH-TC14PE and Thermalright Silver Arrow SB-E start at $90. Absolutely universal and reliable retention, simple installation, compatibility with tall heatsinks on the VRM components and tall memory heat-spreaders, strict and stylish exterior – what else could you wish for? I think this model has it all. Although some restless overclockers would probably rave about something like “Heligon HE01 Extreme” with two large symmetrical heatsink arrays and a couple of SST-FHP141-H fans… I am sure that a super-cooler modification like that would undoubtedly take over the lead in the CPU coolers segment. And maybe SilverStone will try to make our dreams come true one day? Well, all we can do is wait and see.
