Any existing LGA 1700-compliant air and water coolers should fit onto existing motherboards as the socket type is the same. If the rumored specs are true, then there is no major increase in the TDP requirements either, so your existing PSU and CPU cooler should be fine still in terms of fit.
Having said that, we don't yet know quite how Intel's 13th Gen CPUs throttle under continual load. So if you are likely to stress a CPU with use, we'd recommend waiting until there are verified thermal and throttling results. That way you can choose an appropriate solution as needed.
