It only really affects 4k 60p, 8k. I just know what temperature my camera is and never alow it to reach the waning temperature, which in my case at ambient temperature of 85 - 90 F is at 115F at the back of the camera. In which case I've recorded 45 min and 32 minutes on 128GB CFexpress and 128 V90. No problem for me. If I want anything longer I will just use an Atomos Ninja 5 or a fan unit. No need to worry about the Cool down timer if it never overheats. At alarm temperature the card slot can get anywhere from 112 - 120 F. Canon will most likely change the Cool down timer, but not the alarm threshold. I set up an Excel chart with all my modes, settings, threshold temps, and times. I'm good. I don't need any hacks. I will never record more than 30 minutes anyway. If I do, I won't use 40 60p.Generally, in the USA, a modification, temp or permanent, that defeats a built-in safeguard would violate a warranty--if the manufacturer knew about such a mod.
But this all seems too desperate too soon. I'd think somebody who depends on highest quality 4k video would have dedicated equipment.
Basically, what I'm seeing are people who have expendable funds playing with gear that has been tagged as problematic and/or controversial. Some of the "experiments" have been illuminating! Such as running to an external monitor without the cards in the body, resetting the overheating timer by removing the internal battery...Makes one wonder if Canon's own engineers are at least this clever!
Also makes me wonder when Canon is going to have some breakthrough news about this mess. Can't google for new reviews without seeing the blasted overheating hyperbole popping up.
