Some versions of the MX-4 come with a spatula. This guy seems to be

The guy in the YT spilled on a few places, but he seems to be alright.
In comparison to others he uses very little paste, seems even less than
the 'pea' a lot of people advise.

Good to know.

I can remove the heatsink without a problem.

That's a good thing, right? (-:

I'm making a note of that. I bought the PC in 2012, so there's a good
chance it's the CPU and not the PSU that causes the shutdown?

The heatsink I have works with two clamps (?) which have to be attached
left and right and then you pull a lever to tighten it to the CPU.
