PC Power & Cooling are using a 140mm ‘B1402512H’ ball bearing Globe fan. This is rated to spin up to 2,000 rpm. We have seen this used in several other units in the last year.
This PFC design is very clean (Super Flower are the partner), with two long heatsinks separating the components. It is formed around a beefy single +12V rail.
This particular design is using high grade Japanese capacitors throughout both the primary and secondary stages. The main primary capacitor is a Nippon Chemi Con unit rated 400v 560uF 105c. Nippon Chemi Con capacitors also feature in the secondary stage. The metal modular connectors should also lower resistance.
The hardwired cables are sleeved well into the chassis and are tied firmly into place with a rubber cover surrounding the sleeving.
