Thermalright HR-02 Macho Rev.A good for Ryzen 3900x? (convex base, die size)

[Warden777]

I'm currently deciding if I should buy a new cooler for my 3900x rig i'm about to assemble.

Stock cooler seems pretty fine with just 1% performance gap even compared with more expensive cooling solutions.

On the other hand room temperature can reach even 35/38°c during summer and my rig will be used for long rendering session(even 8/10 hours) therefore i'm not really sure.

I'd really like to use my old CPU cooler from my previous rig. A Thermalright HR-02 Macho Rev.A bought in 2013 ( http://www.thermalright.com/product/macho-rev-abw/ ) but im concerned it wont perform well due to 3900x IHS and different die size compared to older chips. Macho Rev.A also has a convex base and i'm not sure if this could be a thing.

As I want to restrain my budget on this one I'd prefer to keep one of those 2 but I'll buy one if needed.

Do you have an am4 bracket for the cooler? If not and it’s not available you’ll need a new one.

Check out this thread on overclock.net

In short, yes it will be good, more complicated, you may or may not benefit a little bit from lapping the cooler.

I use Macho Rev B on my 1700 overclocked and love it. Planning on getting another one whenever I get another CPU because the price/performance is amazing.

My case is a Fractal Design Refine R5, so it's similar to yours.

I don't know about mounting complications with the older model.
