Water cooling an 8K RED

@no_connection as awesome as that would be, i think it is not practical. At least for desktop PCs, high quality air cooling is quieter, smaller, and better at cooling than water cooling especially after a long run time once the water heats up. If cooling is a priority, redesigning a studio camera around proper air cooling would likely have better results. Moreover with water cooling there is a much higher chance of mechanical failure or leaking.

Sure you could stick a giant heatsink to the back of the sensor and have a larger box, it's all the same except where you mount the radiator/heatsink.

I would still want to see a solid block with sensor, mount and stuff with fittings on it, as long as you have thermal shut down it shuold be ok.

Or maybe a block with a flat back, then you can stick any heat sink or aio of your choice to it.

True, its basically down to whether the block it attached with heatpipes or liquid tubing over a potentially longer distance though overall air cooling would be smaller and lighter.

It seems more worthwhile to just use more efficient ASIC chips instead of FPGAs. z cam has tiny cameras shooting insane frame rates and great battery life without active cooling.

CPU or encoder chip is really not the problem, you can cool that with a relatively small heat sink and you will be fine, it really does not take much to actually process an image. What heats up is readout of the sensor and blanking it, and the lower rolling shutter you want the harder it gets. Tiny sensors mean less distance and less resistance so less heat. That is why Sony needed BSI to stand a chance while gh4 shot 4k just fine.
