Summary: Impressed how given its size it was still able to install without blocking any DDR slots. It performed very well and all at a very quiet noise level. SilverStone may not yet be a household enthusiast name when it comes to cooling products but the Heligon HE01 is presenting a strong argument to make that a reality.
Summary: **edit Fan was caused to be louder because I had installed fan clips on both sides of the fan, with only the pair attached to the large side there is less noise, I now find it to be acceptable, though still not on par with Noctua. And in performance mode it's totally unbalanced, shakes the whole cpu cooler. Fan seems a bit loud, warrants further testing. It's certainly not bad, but it might end up getting replaced by a noctua in the very near future.
Pros: looks good, works good, no memory clearance issues
Cons: manual isn't great, back panel can come close to solder points on some mobos, fan is louder than expected on quiet setting.
