One assumes new thermal paste is required when re-attach the van?
Do you mean the fan? If I remember correctly, there was no thermal paste attaching the fan to the motherboard or the surrounding components. It was just housed within the casing attached via screws as shown in the images.
Ryan,
Thank you for your reply.
Yes I mean the fan, sorry. Step 5 you remove the 3 screws for what I assume is the heat sink. I was asking about that as it looks like the the processor is under there and seems to have thermal paste on the top.
Chris,
I see what you mean. It's on that left side of the housing. It does appear there is thermal paste there.
I'm going to be honest with you. We did this in class with non-functional devices, as you could probably tell since we had no hard drive in ours. We did not have access to thermal paste nor was it necessary for us to reapply any since the laptop didn't work from the start. I'm sorry if we provide no guide on how to reapply the thermal paste and I wish you the best of luck in doing it! I am sure there are some other guides on here that include working with thermal paste, if you are not already familiar with it.
Ryan,
Thank you for your reply. All makes sense. Not used thermal paste for years, never had to remove a heat sink for ages.
I can work that out based on the originally paste. Shame it has to be removed though as I’m actually replacing the keyboard\palm rest. The machine is not overheating so I’d prefer to leave well alone if I don’t have to disturb it. Actually, looking at the pictures, it looks like I could just remove the fan screws and leave the heat sink in place,
Thank you for the guide though, good to see it in pictures.
