Dunk, I am pretty sure I have noise reduction turned off on my D5300, but I will check that. As a matter of practice I always turn noise reduction off in my DSLRs, It was certainly never used in the Canon. Of course I shoot darks and bias frames. I think I picked up the D5300 setup programming off CN.
Here is one:

Rick makes a good point, when using a DSLR we have to go through the setup menu and turn off all of these sub-routines that some programmer thought were a good idea and which generate processor activity (hence heat and maybe unwanted AP outcomes).
My venerable ASI1600MM-C has the Olympus OM-10 (Panasonic made) sensor, in its mono form, has very little in terms of software control (and programming interference) other than shutter, download, etc functions; and that is all we need. If DSLRs came with an AP mode, which turned off all the internal gingerbread programming, that would be ideal, but doubtful as a sales success with the public. People have come to expect all that gingerbread, and imho it is one of the things that continue to make DSLRs expensive. The version 1 ASI1600 is pretty much the digital equivalent to my old Pentax KX film camera.
