Probably needed to replace the thermal past that was compromised when your disassembled it.

It would have been nice of the OP had mentioned that you don’t need to take the %#*@ motherboard and heat sink off to dissemble the main body.

And mentioned that you will need to have thermal paste available to replace the thermal paste you ruined by removing a motherboard and heat sink you’d hit even need to remove.

I don’t know why people are praising this guide. It is terrible, incomplete. Lacks detail. Hand waives critical steps and instructions.

It is a terrible guide, one of the worst on this site.

I have been trying to figure out how to “life the front led away from the headset” for two hours. Each gentle attempt risks destroying it. Worst and most clear instruction I have ever seen.

And that is after trying to deduce what the OP meant multiple times, each with an intuitive leap of faith; rather than clear instructions.
