I had a look and I can't get to it without removing the massive heatsink. Which I don't know how to do yet so I'll need to google that thing - it looks like it should just unclip somehow.
I don't have any other machines these days, at least, not desktops to test with.
I fitted one of those coolers in a PC (in fact I've giving that PC away if anyone wants a silent PC) and don't remember it being particularly tricky. I think it is just those 4 screws you can see to remove it.
It's ~8 year old.
