Seasonic M12 II Evo 850w - fan question, correct or replace

So, very niche question first. Bought the above psu ages ago hoping near silence until gaming like this review suggests

but instead I think my fan is constantly spinning even at low loads, like this review

Question that i almost certainly know the answer to: is there a way of engaging the fan curve that was promised on the box?

Assuming all of the above comes to nothing, spec me a replacement.
Modular, ideally with around 3 inches of unsheathed mobo connector (installing into pure base 500 so not much cable on display)
Very Quiet - some noise when gaming is fine, the rest of my fans are all currently below 500 rpm on low load

Currently rig: b450, 3600, 1660ti, aio, few case fans and drives. Would not rule out a more power hungry gfx card in the future but nothing planned.

thanks in advance

also hope the links are ok

I suggest this:

My basket at Overclockers UK:

1 x Seasonic Focus GX-750 750W 80+ Gold Modular Power Supply= £114.95

Total: £125.45 (includes shipping: £10.50)

With outdated low efficiency it's better for long term reliability that fan actually does something instead of just sitting there.
Even small airflow is lot better than stationary air.

Anyway you don't need that size PSU.
550W PSU would handle easily two 1660 Tis.
650W PSU is enough for basically any graphics card with that frugal CPU.

Phanteks AMP is currently the cheapest 80+ Gold with 10 year warranty.

solid recomendations both reading reviews thanks, anything to chose between them for the difference of a few quid? anything even quieter for up to 30 more (at the top end)?

thanks

I'd go for the Phanteks, hardly any difference. Both have a Semi passive mode fan
