Do you mean rad or AIO?
Will you be overclocking?
You post poses more questions tbh
Doesn't the only x99 ITX motherboard out there have a slightly odd socket? IIRC it comes with an adapter for certain AIOs like the H100i.
You do but I have the adapter from AseTek which I got from eBay![]()
So that means it presumably only works with Asetek AIOs?
Don't go mental on the cooling because if you are using the Asrock ITX board your limit will not be cooling it will be the board itself.
It's no overclocking monster and concessions have been made to make it that small.
