Yeah definitely not keen to take it out in case I screw something up. I'll send it back to Ken and send him this thread URL for reference so he can understand my point of view as well. Hopefully he can take special care when applying the next paste (especially if it's liquid metal). He's been great to deal with, so I definitely don't have any complaints. Not sure if they made a mistake with the paste or screwing the heatsink back on causing uneven pressure, but I have high hopes that everything will be corrected. Thanks again for your time in replying to the thread. I'll make sure to update the thread when I get the laptop back with some more tests/temps.
