Xbox series X, Liquid Metal upgrade not turning on

For context I disassembled my series x to replace the thermal compound with Liquid Metal. I followed a guide and reassembled the console.

I powered it on and it booted up.
I ran it on the menus for 30 mins it was fine.
I put a game in and five minutes in it powered of.

The Xbox chimes, lights up for a second and turns off.

I put conformal coating on. I checked all the wires
Not sure what I did wrong.

Any help would be appreciated. My disc is still inside the console and can’t get it out because it can’t hold power for more than 1 second.

On the disc of the stand is a tiny hole on the outer circle in hights of the disc drive. If you push a needle inside it will release the spring mechanism and the disc will jump a bit foreward und you can grab and pull the disc gently out of the drive. Don’t ripp it out!

I don’t get it why someone uses liquid metal on a system which is well designed for thermal paste. But ok. You probably got liquid metal in places where they don’t belong and now shorting something out.

Do you have picture?

i dismantled everything and found a tiny drop of LM on one of the components surrounding the apu. Oddly enough the conformal coating was not entirely covering that one piece. I cleaned the area and reapplied conformal coat, as well as check all neighboring components for scorches and residuals. I am waiting for the CC to dry before reassembly, then test. Fingers crossed. And the original thermal paste was so thin and non existent on the apu it was due for a change.

The thermal paste is there to fill gaps between the APU die and the copper plate of the cooler. If the thermal paste is close to non existent on the die and mostly pressed out from the contact zone, it is a good sign for two allmost even surfaces touching each other.

Ok I reassembled after the initial cleaning. Currently it is displaying properly. I am letting it idle for 30 minutes before running a game. Keeping you posted.

Update: The console has been running smoothly with Cyberpunk on Raytracing for over 30 mins. I have a temperature sensor on my xbox to monitor the outflowing heat. Prior to LM, when running cyberpunk the sensor would display up to 104 degrees. Right now with LM, the outputting temp is showing 85-88 degrees. As of right now the Series X is running much smoother and consistently. LM success.

Nice. 15 °C more at the upper end for hardware hungry games makes a difference. :slight_smile:
