I'd probably either keep the box cooler or upgrade it to something more substantial. The 212 Evo is better than the box cooler, but not substantially so. It's more for CPU's which don't come with a cooler, or to replace Intel box coolers. My advice would be to go for a mid range AIO, Chonky Air cooler, or keep the stock cooler.

I've dropped the 212. Was going to get the Scythe FUMA 2
The FUMA 2 is a strong middle ground, I wasn't sure about it before, but just had a shifty at this video. The price to performance is looking strong.
By the looks of it said would be a significant upgrade over the box cooler.

Ended up getting the 280mm for £80 from elsewhere
Fuma 2 was basically £60 after delivery. £20 for an upgrade, maybe overkill? but eh, it's been bought and will be here tomorrow
