Good evening,
Personally, I'd advise you to get at least one with a 240mm radiator for an AIO cooling system.
In your price range, there are, for example, those from Cooler Master, which I actually installed in my girlfriend's case just a fortnight ago. If you have an RGB header on your motherboard, you can even use it to control and change the colours.

Cooler Master Liquid ML240L RGB (5.20cm)

Kind regards
Niklas
