It's not quite fair to compare our Shark Force 120 with other thicker fans because we can't bend physics to make a 25mm fan outperform a 30mm thick fan unfortunately. Our goal was to create the best standard sized (25mm thick) fan we can so that includes using genuine Panasonic/Matsushita-licensed Fluid Dynamic Bearing (FDB) which is a more expensive bearing than one used in the Phanteks T30. But by far the largest cost was R&D. We were originally inspired by the Speedo swimsuits with shark skin surface that swimmers were wearing back in the 2008 Olympics to break all sorts of world records (which were banned the following year). Back then, the technology just wasn't available to us to mass produce fan blades with patterns like that so we had to wait about a decade for the production technique to improve before we attempted grafting shark skin-like pattern on fan blades. After numerous prototyping and testing of different patterns density and ribbed sizes, we finally settled on the current one that was capable of making the fan quieter spinning at same speed as an identical fan without the shark skin pattern.
So yeah, if you are looking for one of the best standard sized (25mm thick) 120mm fans available, we have one in the Shark Force 120.
If thickness doesn’t matter, we also have a 38mm thick model called "FHS120X" that you can check out with 143.98CFM airflow rating and 11.66mmH2O. It costs less than the Shark Force 120 too!
The construction of the Shark Force 120 is very solid, we've presented this fan at tradeshows and in-person meetings with customers. Everybody that held the fan in their hand said they can feel the quality. Again, we used genuine Panasonic/Matsushita-licensed FDB, it's not that special for sure since it's been out for a couple of decades but it is still considered among the best (and expesive) bearing you can use on a computer fan.
We understand that being a small company trying different and unique products would invite doubts, but we thought we have earned enough creditibility over the last two decades to show we at least know what we are doing when it comes to performance, right? Of course the Shark Force is better than the golf ball dimpled fans we had before!
