I am in the market for an AIO for my 3700x. I plan to have a decent OC on it. Looking at a price range of about 130 USD or less, and a 240mm radiator. Thanks.
Any good 280mm or 360mm AIO will do the job. I have the Corsair H150i Pro and it has been great from day one launch. Cooler Master, Corsair, NZXT and deep cool will all do a good job see below from circa $100 to $140 ish...
