In this repair guide, I show how to clean the fans and heatsink, and replace the thermal paste on the RAZER BLADE 15''.
The operating temperature of this laptop is normally high. The CPU temperature idles around the 55 degress celsius mark. When gaming, the temperature can rise up to >95 degrees.
For my particular case this Razer is around 18 months old and regularly experienced thermal throttling hitting core temps above 100*C. As you will see below the fan and heatsink were very dirty. Following the instructions of this guide, we managed to lower the running temperature to around 85*C. So, it's well worth to do it!

You can check your laptop's temperature entering the BIOS. Otherwise, the free and open source Core Temp's (https://www.alcpu.com/CoreTemp/) will show you the readings from the BIOS.

The internal power connector is soldered on motherboard or connected with cable to motherboard ?
It seems to be soldered (see image on step 7) but I would need to reopen the laptop to confirm.
