its actually ramsink from 亨利 ram wc block, I dislike its block so I just reuse its heatsink, u can search by the name akasa in tb, it comes with 4 pcs, 2 large 2 smaller for 2 sides, floor and ceiling I guess
why not? its easilier for routing in my case, and that hole is placed lower than the offically recommended setting so there's more water to drain when needed to replace coolant, reroute or replace parts.
performance wise, it seems as strong as the offical settings even though I dont have the meter......will add in later
