Still debating on if I want to do a TR build or not but if I do I think I would prefer to wait til manufacturers came out with coolers that were built for Threadripper. Ya gotta think these things are gonna put out a ton of heat and I think it would be better for overclockers if we had a block that fit the entire surface of the CPU. I understand that the blocks out today supposedly cover the heat spreader but I'd still prefer one that covers the entire surface. Heat spreader or not, the entire lid is going to dissipate heat.
