Seasonic Prime Ultra Platinum 1300w (80+ Platinum) disturbing fan noise in Hybrid mode

• Easy fix for the Seasonic Prime Ultra...
The system is running at 200w and the 1300w PSU made by Seasonic is spinning the fan without any obvious reason whatsoever, every 5-10 minutes, making lots of noise in a be quiet! case fans with Noctua cooler CPU.
Touching the PSU, it's all cold, with a single spot warmer to the top.... the air coming out of it is cold, not even warm.
I had to mount the PSU with the fan oriented upwards just because with the fan pointing downwards it starts spinning every 4-5 minutes.
Please don't laugh at my PC case, it's from 2006, an iron made Chieftec that I really loved so much that I ever used since then :)
Later edit:
Seasonic responded to my ticket and the PSU is working fine. It is intended to spin the fan as soon as the conditions are changing even by a little bit, beeing a heavy load, almost industrial PSU.
Don't worry if your PSU is doing the same. Too bad they didn't use a more silent fan, but it is what it is.
The product itself is working perfectly.
Thank you Seasonic for confirming everything's fine :) I was worried.
