AMD Threadripper 1900x
Asrock x399 Tachi - BIOS P2.00
Enermax LiqTech TR4 240 (cooling)
No Operating System yet but will be installing Windows 10
No overclocking (all the settings in default)

I just built my rig and turned on.  The mobo came with bios P1.30.  It showed 34'c on the UEFI Easy Mode and 56'c on the Advanced Mode. 

I updated the BIOS version to P2.0 via instant flash over the network.  Now the CPU temperature on both easy and advanced modes reads 66'c and never goes +/- 2 above this number.

Mobo: 33'c
M2_2: 28'c
VR Temp: 32'c

CPU Vcore Voltage: 1.424

The room temperature is about 23'C.  I have another PC in the same room that reads 34'C on idle. Other than the CPU temp, everything seems to work.

Am I dealing with a bad mobo, CPU or the AIO?

I own also a AsRock X399 Taichi + 1950x (not oc), and i have the same reporting as you, 65C on bios with P2.0, but on windows 10 the temps are 30s, i think its more the display on bios.  For reference im using Noctua NH-U14S TR4, which beside your Enermax AIO is a good as it gets with this setup.

Neither are bad.  Mine reads roughly the same.. a few degrees different.  What youre reading is an offset number.  Tdie is what we need to be checking, but that is the t-ctl temp the mobo is reading.. I've compared it to hwmonitor and that seems to confirm it.  It's 27 degrees above t-die....

To compare setups
x399 taichi
1950x
3.9 ghz oc on all cores
enermax liqtech 240 aio

At idle, you'll see that if you subtract 27 degrees from mobo reading.. you'll be within a few from ambient temps..
