The Silverstone Heligon HE01 CPU Cooler is in the Enthusiast class of CPU coolers.
The Silverstone Heligon HE01 CPU Cooler performed at the top of its price class in cooling benchmarks. Installation was solid and easy, but the instruction manual was a little incomplete. Noise levels were moderate during normal usage, with a low pitch that was not disturbing.
Well, this was certainly unexpected, to say the least. While Silverstone has paved a name for themselves by offering top tier cases, power supplies and fans, their CPU coolers had always seemed like an afterthought, and typically in odd formations that seemed to be aimed at HTPC, but in reality made little sense for any application. The Heligon HE01 turns that absolutely upside down with outstanding cooling in a form factor that makes absolutely perfect sense for the enthusiast.
The Heligon HE01 is a dual tower cooler with six 6mm heatpipes, but Silverstone throws in a fantastic twist to the design. Unlike the other dual tower designs that have passed through our test bench, the HE01 has a slim front tower that allows all RAM slots to remain completely unblocked. To add to this, rather than using dual fans, only a 38mm center fan is used that is capable of a whopping 171 CFM. This is a huge feature for users of RAM with taller heatsinks, and will allow them to get top tier cooling while retaining their tall RAM.
The cooling provided by the Silverstone Heligon HE01 sits right at the top of coolers in its price class, keeping up with the best we have seen to date with ease. The HE01 did not wilt when the OC tests applied more heat, it actually seems to thrive on the higher heat comparisons and is well suited for heavy demands. Surprisingly, switching the fan from Performance to Quiet mode made only a couple of degrees difference at the top end, while bringing the noise way down and putting it in the middle of the test pack in noise output. Performance mode can get a little loud, but this is to be expected when this much air movement is generated.
The 38mm deep 140mm fan used with the Heligon HE01 is a very interesting piece all by itself. With an 800~2000rpm rating, it goes from whisper quiet to mammoth air movement in a heartbeat, and PWM allows for everything in between. A physical switch exists on the side of the fan to put the fan into “Quiet Mode” which limits the top end rpm to 1200. Daily usage has shown me that using my standard fan control curves rarely gets the fan going over 1200rpm regardless, and noise levels are more than acceptable. One thing of note is that when the fan does ramp up, there is a noticeable huff at the start due to the fan’s massive air movement capabilities. It is infrequent, and certainly not enough of a distraction to be a real knock.
Silverstone has definitely made a statement with the Heligon HE01. It is well engineered, beautifully finished and has cooling power that sits at the top of its price point. Comments like that used to be reserved for Phanteks, be quiet! and Noctua, but the HE01 throws Silverstone into that mix, and the HE01 has the advantage of allowing complete access to all four RAM slots. For those about to say that AIO Liquid Coolers don’t block any RAM slots…..you will need to spend over 30% more to get comparable cooling performance to the HE01, it will be at least as loud, more difficult to install and more prone to failure. There is no question that the Silverstone Heligon HE01 is a piece making a statement, and it makes it very well. If you have existing (or simply want to use) tall RAM, or are in the market for a CPU cooler $75 or less, there is no CPU cooler I would recommend over the Silverstone Heligon HE01.
