Quiet enough that it I don't feel something is wrong when it is turned on. Perhaps no R&S unit is going to be totally silent but mine is definitely on the right side of quiet fence - the pink noise just disappears after a while.

The R&S FPC-1500 is completely fan-less and a pleasure to use! I wish the scopes could share the same thermal design. My unit had to go back multiple times for spurious IF overload problems, but R&S took care of it, and ultimately I think it's just a warm-up issue.

I received my RTB 2004 in Dec 2022 (took 6months from ordering) Serial Number 204357 and the fan noise is almost inaudible.  Looks like R&S has used a new fan to the original?
salomonander:
Sorry for reanimating this ancient thread. But does anyone know what fan is used in the newer models. Im also wondering if its safe to try the noctury NF-A8 FLX as a replacement due to power consumption. Old one is specified at 480mW while the noctura as stated with 840mW max and 396 mW typical. Is it a safe replacement?
