Why would you compare super 35 4k60p to FF 4K60p?
We never have to shoot full-frame 4K on the R5, but it is there if we need it.
C70 does not have that option with RF lenses.
Because it is unlikely that one shoots in 4k HQ full-frame and then switch to crop mode for 4k60p, just not very practical compared to FF mode.
It is not the same as having the same crop for all frame rates. Also the cinema 4K crop mode on the R5 is 1.6x versus 1.43x on the C70.
4k60p is better on the C70 anyway, because DGO is still active in that mode.

If the heat has no direct path to the outside camera body, then the entire body will heat soak with local uncontrolled heating, which is what we see. If the heat is led to an outside surface (preferably with a heat pipe), heat will flow to that surface. The total heat output of the camera remains the same. That outside surface needs to be broad enough that the total heat energy is spread out, and also needs to be able to shed heat to the air (i.e. exposed black anodized aluminum not insulating grip material).
If there were a heat pipe to a base plate with an exposed aluminum/mag base, video shooters could mount a heat sink in place of a battery grip and increase the thermal capacity of the camera a great deal. At design time, a camera metal body that's partly exposed at the baseplate and a less than $10 heat pipe would be the only changes. I suspect the new camera will be something similar, but with the grip heat sink as an integral part as that's the obvious way to go.
I'd probably be happy with some insulation in the two spots that have the firmest flesh contact: middle finger knuckle under the shutter release, and thumb on the rear. Some kid of aftermarket stick-on might do.

Can you specify what you mean by a "warm" day - I regularly use my R5 in temperatures of 30ºC and I'll typically shoot 500 shots in the space of 3 hours. My grip never gets hot or uncomfortably warm. The back of the camera gets warm, but never uncomfortable, and I've never had any issues shooting stills all day (mostly in short 10 fps bursts).
The high temp that day was 90F, and I was mostly in the shade.

With product differentiation between the R5 and the R5c, there is room to hope that some day the R5 might actually get a set of firmware upgrades focused on stills. (Choice of FPS on electronic shutter, for instance.) That's the dream.
I'm sure they will save that for the R5 II.

I’m having the same kind of hesitation but with a Sony A1 instead of the C70… But then if I enter an ecosystem I’ll be kind of stuck in it, so maybe I’ll just buy an R5 and then replace it with a r5c… I’m just totally afraid of the overheating issue, as I intend to shoot a lot of long form video in 4KHQ, even with a ninja it seems to overheat
If you absolutely need to shoot long form and the Ninja V doesn't give you enough time for the shooting you need to do, I would also suggest getting a dedicated cinema camera. The A1 does not have as many overheating issues as the R5 had prior to the firmware, but there are still a number of reports that it does overheat in 8K over extended periods. In non HQ mode, the Ninja V allows recording with the R5 for over 3 hours according to some testing I have seen. In HQ mode, it seems to top out at a little over an hour. That is personally enough for me, but if you need much longer recording times, even the A1 might not be enough. I would recommend buying a dedicated cinema camera like the Sony FX6 or a Canon C300 Mark III. The plus side is you will get all the professional tools you need for shoots as well. XLR, built-in ND, V mount batteries, etc.

Yes, but those tests are taken indoors.
In these days, the outdoor temperature here is up to 38°C, and this is where things can start to heat up rather quickly (and cool down slowly) and adding all that extra set of accessories connected via micro-HDMI can cause other problems.

I did 2.5 hrs of continuous recording with R5 and Ninja V at 32C (90F) temp (4K HQ) and found that the recorder heated more than the R5.

Who says you need to shoot 4K HQ full-frame mode either?
I shoot 4K crop mode a lot of the time.

Unless it also comes with its own line of smaller mount and cheaper lenses I’m not understanding the need as you could just crop tighter (the R5 has a 1.6x crop option in camera) the R cameras are already smaller in form than a dslr, any smaller and they’d be cumbersome to use like the Sony bodies.
I am not sure why this question keeps coming up.
The R7 is expected to be a lot cheaper than the R5 and the resolution is expected to be a lot higher than the R5 cropped.

I do agree with what you said, but comparing neurons and transistors is kind of pointless.
CPUs are getting with each interation more enery efficient not less.
Well, my move to neurons was a bit of irony, but not really pointless. With more and more AI and machine learning in cameras, I expect artificial neural networks to play a growing role. With artificial neurons built by say 400 transistors, the problem of inefficiency is even more evident. I know what I am talking about, I once specialized in semiconductor physics during my studies, and I am editor of a physics journal that publishes a lot of scientific papers about solid state physics related topics.

But, don't take my comment personally, I just wanted to show that a hot camera body mustn't be a bad thing ;). If you have a MacBook and do heavy-sided image processing with it on your lap, you experience a lot of heat from the processors, too.

I shoot 4K crop mode a lot of the time.
For a hybrid camera, having the same crop in photo and video is always best in practise when switching between them.

And as I wrote: bigger 1.6x crop, no DGO, overheating in 4k60p APS-C mode.
The C70 has inferior AF, but most people who have both the R5 and the C70 prefer the latter, and not just because of the overheating.

I hope they really do call it R5c to mess with all of the people who like to make up new names for their Mark I bodies after new versions come out by appending a "c", e.g. calling the first 5D DSLR the "5Dc".

Yeah, I know that. But I need a hybrid to shoot both video and quality stills. An FX6 or C300 won’t shoot stills for that matter.

If you use this crop option in an R5 then the file is only 17mp whereas an R7 could have say a 30-35mp crop sensor.

Most people wanting an R7 plan to use it with FF telephoto lenses and RF-s versions of these wouldn't be significantly smaller as the front elements would be the same size and only the elements at the camera end would be a bit smaller.
For example an RF-s 600mm f/4 would still have a front element of at least 150mm diameter as the entrance pupil is 600/4 = 150mm.
The price would be similar to FF for L quality glass and at most a weight saving of 5%.

For people such as myself who want a crop sensor R camera for birding etc. a smaller form factor would be a disadvantage, my dream camera would be an R3 body with an aps-c BSI stacked sensor of about 30-35mp which I could use with long telephotos for birding (and also with a Metebones EF-RF speed booster I could use full frame EF glass with only a slight crop which would be a bonus)

In terms of pricing if Canon made an aps-c version of the R6 (e.g using the 90D's 32.5mp sensor) then I'd expect the pricing to be similar to or slightly less than the R6 and I'd happily buy one.
If they went all out and made a full-on pro aps-c version of the R3 then I'd be prepared to pay a similar price to the R3 as this would be the best birding camera ever made.

I'm not expecting a bargain similar to my old 7Dii , I want a significant upgrade on it and I'm prepared to pay for it.

I lot of people question how big a market there is for such a specialised birding camera but Canon (and other companies) have spent a lot of money on developing specific eye autofocus algorithms for birds so they probably think a significant number of people shoot birds.

Sounds like for your needs you would be better off waiting for the R5c. For my needs, the R5 works very well as a hybrid shooter. I just use the C70 for long form.

Hell, I live in New Orleans....it's pretty much almost that warm when I wake up about 7am.

Hot?

LOL...my AC has been on since April and likely won't shut off till early November.....add humidity to that too.

Hm when will get the R5 &6 an QoL update to lower the FPS in photomode etc…

Will there be also a R5a?
If I could bring a new Canon R… I would bring something <R5 or alsp <R6 but with 30MP and ~10-12 FPS, IBIS and dual cards.
That's about the R camera I would like to if it was in a body with good ergonomics and controls ... although with Canon's approach to pricing, who knows how much they'd charge for it.

Have you asked Canon or the shop where you bought it about this issue?

Most R5 users never seem to have this problem shooting only stills .
Have you installed the latest firmware ?
Sounds like your camera is faulty

Can’t wait, I have a project in a couple of weeks with days long shooting and I already sold my last camera and bought the Ninja, so I just miss the new camera now. Need to make a choice tomorrow, either buy the R5, pray it doesn’t overheat on me and resell it when the R5C is out, or just buy an A1. I’ll buy a whole set of native lenses with either and the total amount spent camera included will be the same in either case, but once I’d have done that I guess I’ll be in one ecosystem (Sony or Canon) for a long time. I crave for the superior IBIS and DCI of Canon, on the other side I’d have the state of the art 50mpx stacked sensor non-8Kraw non DCI capable, non-overheating but reliable, less “cinematic” more “video” and photography killer machine. I have been hesitating for weeks, because one way or another, it will be one brand for years. Tough choice
