You will need a mounting kit for the D15 to work on socket AM4 as it isn't backward compatible with older AMD mounting holes.

OK thanks for letting me know.
There is actually an AM4 version of the D15 but it doesn't look like OCUK have it listed. Might be worth asking if they are getting any in stock.

Perhaps a 1700 CPU would serve just as well as a 1700x?
No games, just 4K video editing and H.264 encoding, what you think ...or best to go for the 1700K?
Thanks.
Go with the 1700 then, as you can always overclock it a bit to match the 1700X.
...You will get thermal paste with the stock cooler and the D15 either pre-applied or in a tube/sachet).
I often wondered with the pre applied past, is it OK to keep it on or wipe it off and use something like Artic Silver instead?
Thanks.
The Noctua D15 comes with very good thermal paste (Noctua NT-H1) so you don't need to buy anything else.
