Reusing a Noctua NH-U9B SE2 for Ryzen

[Grimley]

As per title folks.
I'm planning to slowly upgrade to Zen 2, but to save a bit of money I was wondering if I could use my current CPU cooler with an AM4 kit. Would it be up to the task being an older cooler or should I upgrade the cooler too?
Opinions please.

I can only give it a try & keep an eye on the temps, then if its not up to the task then I'll upgrade. Thanks guys.
