Hi guys,
So I read the whole thread ... following situation:
I am currently building the following SFF PC (and Hackintosh):
- Ryzen 5 2600
- 16GB RAM
- Radeon RX 5600 XT ITX
- Metalfish K3 Case
I already had the following PSU: https://seasonic.com/sug
worked just fine! 
Then I tried to mod the fan to a Noctua 40mm 20mm thick fan.
As someone already mentioned, I had to reverse the poles of the cable I attached to meet the original fan (or rather its polarity) - I did just that.
but the Noctua fan never started spinning!
I tried everything ... in the end not even the original fan would work anymore! My multimeter reported 8 volts, but as soon as I attached ANY load (--> any fan, no matter which one), the voltage dropped to 0.01V.
--> I RMA'd the PSU now and want to order a new one!
Problem is: I am from Europe (Austria) --> as far as I understand it, Taobao is out of the question (no idea how you guys order there - do you speak Mandarin?).
I am a bit lost on what to do now:
- Order same Seasonic 300W again and leave stock fan: loud!
- Seasonic 300W with fan mod: might break it again, no clue how I broke it. Still don't understand what happened!
- Order Silverstone 350W (https://www.silverstonetek.com/product.php?pid=784) - everyone says this is VERY loud!
- Order something from aliexpress - which one?
I hope you guys can help! Thanks a lot in advance!
best, Patrick
