Did you replace your i5 motherboard for an i7? Was everything ok?

I’m thinking about doing the same…

One assumes new thermal paste is required when re-attach the van?

Chris Rivers - Reply

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.
