Rather than disconnecting your fans, get yourself a good fan controller. Then you can dial in the best compromise between noise and cooling performance. Most fans are actually bearable once you slow them down a bit.

I checked your work against the manual and I don't see anything obvious. Solder joints may be a problem as some still look iffy and I can't see jumper J2.
I see some potentially bad solder joints:
Pic 2 right below the left tube socket.
Pic 2 to the left of the right tube socket.
Some of the other pics are too blurry to be able to see much.
Some additional heat or on time might help flow some of those joints better.
