Also consider the new Icegiant ProSiphon Elite [0]. Mine is arriving in September (due to Coronavirus related delays) but initial tests of prototypes by LTT [1] and others showed better cooling than AIO water cooling. Also since it uses dielectric fluid there’s no risk of leakage and frying your expensive computer. It’s $169 MSRP but based on what I’ve seen seems worth it. I’m not associated with them in any way just think it looks like a cool new product!
