Alphacool Core RX 7900XTX Merc 310 with Backplate hotspot isues

[Hypothermia]

hello i just instal this waterblock and hot spot is 100-110 degrese on metro exodus gpu max 51 degrese repasted few times already. any idea guys?

AMD has often problems with the PCB since the RX6xxx series, whereby the PCB is not straight but wavy. In addition, the GPU DIES are not straight, but also curved. As the GPU hotspot sensors on AMD sit exactly on the GPU DIE, this is an indication that the GPU DIE is not in full contact with the cooler. The only solution here is to straighten the PCB. This can be done in different ways.

1. try adjusting the torque of the screws so that the PCB straightens out.
2. try placing additional heat conducting pads on the back of the PCB to push the PCB forwards and thus straighten it.
3. use a viscous thermal compound on the GPU DIE like the included Subzero and place a thermal pad behind the GPU DIE that completely fills the back. Pay attention to any components in the area and adjust the thickness of the pad accordingly.

and if i use smth like this istead of thermal paste?

and if i use like 4mm thermalpad on gpu die back to push it down a little it would help?

4mm will be to thick. The Backplate has been designed for 3mm pads as long as the pad is not sitting on any components. So if you are placing the thermal pads on components with 1mm height. You can only use a 2mm pad.

hello so i should change pads size in backplate? Or somewhere else?
