Introduction

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.

    • Position the laptop as it’s shown in pic 1.

    • Remove 6 torx screws and put them on the magnetic mat

    • Insert an opening pick and slide it around the two shorter sides to unlock the pins

    • Slide the case towards you. The goal is that the 3 inserts on the case slide out (see pic2. Yellow marks)

    • Use a spudger to disconnect the battery. It is the pop up connector with the orange cable

    • There are two Philips screws in each fan. Remove them

    • One is easily visible.

    • The other one is under the black plastic cover (see orange markers)

    • Do this on both fans

    • If you want, you can carefully remove the connection to the motherboard (yellow circle). XetThe tested this and could be removed, (See comment below)

    Fan's connection to the motherboard IS removable. it just takes some careful wriggling to take it out of the connector.

    awesome! I am sure that made the cleaning process much more comfortable. Thanks for sharing!

    • Use the brush and dust blower to clean the fans

    • You might also use the tweezers to remove debris

  7. uB5CwNKsPgPdUCq2
    • There are 10 Philips screws with a spring. Unfasten them

    • Now lift the heatsink carefully. The thermal paste offers more resistance than normal.

    • The heatsink is a heavy, copper metal component.

    • Put the fans back and fasten them

    • Reconnect the display ports and put the tape back

    • Reconnect the battery

    • Close the case

    • And it’s done! Test the working temperature now it should be much lower.

Conclusion

To reassemble your device, follow these instructions in reverse order.

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.
