Re: New Technobit project HEX4RB - 4 chip RockerBox ASic based board
250W TDP at 26dB (huge, using 2 120mm fans) http://www.bequiet.com/en/cpucooler/482
350W TDP http://www.techpowerup.com/141811/zalman-announces-cnps11x-extreme-cpu-cooler.html
IMO the only fan/heatsink coolers that can handle such wattage are massive monstrosities that almost certainly cannot be shipped mounted or they will snap the PCB/mounts, and would require a big open case to offer the airflow. Closed-loop liquid cooling seems like the obvious winner

No point, the dogie guy will dodge this scenario as he insulted me while being delusional and pretending that I was incompetent for pointing out his failure.
Don't forget those are manufactured specs. An example is gigabytes windforce cooler which they claim can dissipate up to 600watts.

He mentioned high end air cooler or basic 120mm watercooler. I pointed out a dual 120mm closed loop cooler could do up to 300w but would love to see his unicorn air cooler.. Somehow he thinks quoting me as If I can't read and chose to not post this unicorn cooler and insult me instead, of course because we all know typing 3 words is easier than 30
I don't think dogie is totally wrong, you *can* find air cooling that handles 350W but as I showed above its often large, top-heavy monstrosities that cost as much as a liquid-cooling solution. That windforce one you mentioned is for GPU so doesnt make much sense in this regard.
IMO, dogie is 90% right - cluster the chips and place mounting holes for common CPU heatsinks. Let the buyer go and get a decent liquid-cooling system from thier local market and most of those can easily take 300-400W TDP for a fair price and small footprint. Additionally, they can be salvaged and used on other equipment in 12 months from now when the HEX4RB is no longer profitable. (or if the HEX4RB underclocks to ~200W TDP in 6mos from now it can be swapped for a more tame air cooler)
