Cooling ENTHOO EVOLV ITX: CPU cooler and fans

I will be moving my computer into a Phanteks Evolv ITX Mini-ITX Case and I'm looking for advice on cooling.

I want the computer to run cool and stable while gaming and I want it to run quiet, preferably silent during light loads.

CPU cooler:
the Noctua NH-L9i is struggling with gaming right now.
CPU clearance is 200mm
What are some good options, would be more than happy to buy used.

Fans:
The case comes with one 120mm but is missing the front 200mm fan.
The case can hold up to 5 fans.
I want to get the fans right before I put everything together but don't want to waste money.
I do have a Cooler Master 200mm RED LED that I can use, are these any good?

Front: 2x 120mm/140mm or 1x 200mmm
Read: 120mm or 140mm

 

NH-U12A if you can afford it, one of the other noctuas if you can't... even the hulking D15 should fit.

 

As above, if you buy a Noctua NH-U12A you will probably never have to buy another air cooler again.

Pricey but as the review on bit-tech says, it embarasses everything else with its quality and performance. It even beats AIO coolers.

An alternative is to buy @kosch 's BNIB Corsair H60 AIO for £48 in the marketplace?

Another alternative is the BeQuiet Dark Rock Slim with is half the price of the Noctua?

 

They NH-U12A is a marvel of engineering but the price is way over budget for my build.
Case: shipping
CPU/MB/Memory/Cooler - £270
12tb storage - £105
Monitor - £270
500GB NMVe - £90
RX 480x 8GB- £110

That last cooler I bought was a Hyper 212+

I want something that will perform well with a moderate overclock.
I did see @kosch 's Corsair H60 AIO for £48 but I wasn't sure if I wanted/needed to pay that much.
Is it a good value for performance given my build?
Do many used coolers go on the marketplace?

The Noctua NH-U12S and Noctua NH-U14S are £53 and £56.
I would prefer to go around £30-40 if possible.

I can't find any comparisons between the Noctua NH-U14S and the Corsair H60 (2018).

 

According to a Hexus review here, the NH-U12A and the NH-U14S are very close (within 1C) in performance (8700K).

According to a TechPowerUp review here, a CoolerMaster Hyper 212X is 7C behind the NH-U12A under load (8700K).

If you can't afford to spring for a high quality Noctua or even a BeQuiet, go for the CoolerMaster at under £30 because it will at least cool your 6700K better than the NH-L9i will - even Noctua's CPU compatibility listing says that the NH-L9i should only be used on a 6700K with a good ventilation case (i.e. more intake fans than you have).

If it was me, I would try the 200mm front fan first and see the result, it won't cost you anything. If you have a couple of 120mm or 140mm fans then it is worth trying those in the front as well for comparison. Make sure you have at least one 120mm/140mm exhaust fan as well as there is no point in loads of air intake if the hot air stays in the case. With you running an RX480 there will be a lot of hot air in the case to get rid of.

Edit: again it it was me, my ideal setup in your case would be something along the lines of 2 x 120mm/140mm intakes with a single 120mm/140mm exhaust and whatever you like for a CPU cooler. My own ITX rig is 2 x 140mm PWM fans as intake with 2 x 120mm Noctua PWM fans as push/pull exhaust on a Corsair H55, cooling an i5 8400 in a Fractal Nano S case. Temperatures are really cool but the biggest thing for me is the silence, I sometimes can't tell if the PC is actually running - but note that I am not running a GPU in my main rig.

 

I've found this to be the best setup, along with whatever the PSU exhausts the 92mm fan on my cheapo cooler I bought to tide me over in NZ still keeps my 3770 in the 60s in a matx case.
