Cooler recommendations for 5800x

I love my fractal Celsius prisma 280 plus
Quiet, installed easily, allowed me to swap to a 5900 from a 3600 with a single screw, as everything else stayed in place.
 
Arctic Freezer II is top choise in both performance and cost.
It has 50% thicker radiator than in most for actually more surface area for dissipating heat into air.
And lacks brand/marketing hype overpricing.

Also high end heatpipe coolers would do fine starting from £43 Alpenfohn Brocken 3.
That Coolermaster Overhyped is just basic 120mm tower cooler and nothing more.
 
If space is at premium inside the case, Scythe Mugen 5 with mid dense fin stack would be actually little heavier cooler than Brocken 3 despite of "moderate" dimensions and step behind the best in performance.

fuma 2 is also more compact than usual dual tower.

Though they use base designed for Intel's concavish heatspreader while AMD uses convex heatspreaders.
So depending on amount of convexity in cooler's base, they might need lapping base flat for optimal performance.
(two convex surfaces make good contact only in small area)
Direct contact heatpipe coolers like Brocken 3 have flat base automatically, because of the way they are manufactured.

I'll definitely take a look at the Scythe Mugen 5, but i was also looking at the Noctua U12A (Although it is a bit more on the premium side).
 
The cooler Techpowerup (any many other reviewers) use is the NH-U14S air cooler, it can keep it under 80 degrees when overclocked. The cheapest place to buy one is on auction websites.

Not sure about the Alpenfohn Brocken 3, looks good value, but according to this thread, 5800X temps can rise above 80 degrees with this cooler.

In "vacuum" NH-U12A would be superb cooler for limited space.
But there's competition and it's half the price costing Mugen 5 weight level cooler with equal number of heatpipes.
And Fuma 2 is some amount heavier.

And to top the high price "poor" Noctua can't even bundle proper screw driver, but only piece of bend iron wire for installing it:

(also base is Intel optimized convex one)
