I found the D4 ubearably noisy, and did not suffer (a measured) adverse temperature/OC change in my system when I swapped back my 1048.
That said, I 'still' can hear a slight rattle from the 1048 (mounted on a sponge), and that through a heavy steel case lined with 'peel and stick' roofing tape, and over my radiator, case, and psu fans. It's an old pump, so I have a new impeller to swap in. It may help.
SPCR did an interesting review of an acoustically insulated, watercooled case built with an insulated box around a 1046 pump and a passively cooled radiator.
