I got tired of having to replace an AIO every couple of years. I'm back to air cooling.
They've sold a ton of Hyper 212's. A couple of years ago a Computex, their booth said they've sold over 3 million. And they still make them. I remember paying $17 for one back in Sandy Bridge era, now they're $30+.
If you can pick them up on sale, like the
all black version is $25 right now.
Thermalright has taken over that budget cooler category in single and dual tower coolers.
Under $35 for a dual tower
Peerless Assassin, and
Assassin Spirit single tower for $18. GamersNexus has covered both.
