Replaced fan with Noctua for quieter operation

KrakenSDR is great! I’ve wanted to have it quieter when running at home so swapped the fan out with a Noctua NF-A4x10 5V which is much quieter. If you do this, don’t connect yellow to anything and you’ll want to replace the M3x10mm screws with M3x16mm to support the added height around the fan grill.

I love this… and will be doing this to mine as soon as the parts show up. Thank you for sharing

I must be very lucky because my fan is nearly silent. In fact only way I can verify it is spinning is to put my hand over it.
