Cooling the VRMs on Asus Prime B450M-A/CSM

Doing a new build soon (found here: https://pcpartpicker.com/list/yRMBYT), and was hoping to cool the cpu with an AIO. However, I'm a bit of a noob, and have recently learned that AIOs can often present the problem of overheating the RAM and VRM. From my research, the RAM shouldn't be too much of a problem in my instance. However, the VRM on this board lacks a heatsink. So, here's my question:

If I were to place the AIO radiator on the front of the case in a push-pull config, apply some aftermarket heatsinks to the mosfets, and put fans on the top and rear of the case do you think I would have sufficient cooling?

Notes: I wish I could do a custom loop, but I'm too afraid (I am a noob, after all). They're also a bit out of budget for me.

I could consider upgrading the motherboard to the ASUS ROG Strix B450-F, but that thing is expensive and kind of ugly in my opinion.
 


You can add a small fan to blow on the FET's to keep it cool. But...are you really hung up on the Asus board? an Asrock B450m Pro 4 or MSI b450m Mortar would be a better choice, with much better VRM cooling and heat sinks that don't care if you're using an AIO.

If you're really needing that one, though, even with a cooler that blows air on it...or an added fan to do the same...you should put some stick-on heatsinks on the FET's. THEN talk about ugly!

I'm not necessarily tied to this board. I bought it before I found out about this problem, but I can still return it. I was hoping to use Asus's Aura Sync to satisfy my horrid desire for RGB capabilities, though.
 
Is that Aura Sync something like an addressable RGB? Mortar and the Asrock Pro4 both have RGB headers, i'm not sure if they are exactly what's called addressable.

I don't see the point in it and have no use for it so have never even tested them on my Mortar so have no idea what the different capabilities are.
