What you have posted does not help to answer the question
Whether the larger size of the 3070 will fit depends mainly on the space available in the case
However are you sure the motherboard is an
asus z590 phantom gaming 4
ASUS
as I do not think Asus actually MAKE a board particularly called what you post
The other problem is that there are many makes opf card with the 3060 chip
For instance the Gigabyte one
GeForce RTX™ 3060 GAMING OC 12G (rev. 1.0) Specification | Graphics Card - GIGABYTE Global
is
L=282 W=117 H=41 mm
moving to the 3070 lets take Gigabyte again as an example
GeForce RTX™ 3070 GAMING OC 8G (rev. 1.0) Key Features | Graphics Card - GIGABYTE Global
L=286 W=115 H=51 mm
so as you can see you need to check WHAT size the 3060 you have is
and what size the 3070 you propose is
You can then measure if there is enough room
Returning to the board
If we take an example from the ASROCK board x590 phantom gaming 4
ASRock > Z590 Phantom Gaming 4
we find it is full ATX form factor
ATX Form Factor: 12.0-in x 9.6-in, 30.5 cm x 24.4 cm
so in theory there should be no problem fitting in a 3070 but you need to check as it depends - as mentioned at the start - largely on case room
