Question VRM heatsink height

[nikosmah]

On the Gigabyte Z390 AORUS Ultra in particular. I'm looking to buy the Fractal Design Meshify C and for a top radiator mount the supported maximum height for top mo/bo components is 4 cm. It says so on their page for that case.
I couldn't find any sheet with the mo/bo overall dimensions so I assume that only an owner would know. Can anyone help, please?

Yes, most of the newer Z390 have the huge heatsinks, they will block the AIO cooler fan.
So you may install the radiator in the front panel, or buy other slim fans to replace the regular size fans.
The slim fan, you can find more, something like this https://www.newegg.com/Product/Product.aspx?Item=9SIAADY5SE4711 or https://www.newegg.com/Product/Prod...lim fan&cm_re=slim_fan-_-35-705-067-_-Product

I contacted Gigabyte's support and they were very comprehensive in their reply. This is an image they attached with the heights of the components at specific points of the mo/bo

measuring from the top layer of the PCB
A.) VRM heatsink only – up to 28 mm.
B.) Plastic cover above the VRM heatsink – up to 35 mm.
C.) Highest point of the big plastic cover – up to 44 mm
Given my case's mo/bo size requirements the board definitely won't obstruct a top-mounted AIO with regular thichness fans of 25 mm.
