    Super late, but figure I'll add: something to consider is heat can shorten the life of a phone, typically through battery, sometimes other components. Yes there's repair and replacement (minus apple products, because, well if you're a techie you know why), but janky as this is, it seems like a valid way to extend the life of a phone for a heavy user, especially with some of the phones that are more prone to heating up.

      buy a small lathe and you can make yourself any adapter related to this kind problems

                          I think you make a mistake with the test of benchmarking whit out cooling , in real situation your hand make the phone cool when it is over heat (because a have a s10 snap and whith hands the thermal throttling is lower than yours)

                              That was my favorite video you’ve ever done. When I’m bored I benchmark phones and tablets while they’re in the fridge. Moving them around on the cold glass every few seconds. It’s fun but I’m too lazy to record the results so it was awesome to see you break it all down.
                              I wonder how a simple small active AirCooler with a tiny battery would work. Or a small portable power bank with one built on.
                              If only I had the tools. (Hint hint)

                                  @Linus Couldn't you just go swimming with the waterproof S10 phone to test thermals? You could swim around in a pool that would essentially be the same as liquid cooling the phone :)

                                              or at last make it copper inside of a hard case...

                                              Dunno if its just my device (tab s2) but this video full screen doesn't scale aspect ratio properly. Been watching a few LTT vids just now, none of the others had an issue. Aspect ratio is fine if not fullscreen. Dunno if its just YouTube or your format or whatever.

                                                I predict this will accomplish nothing. Most of the heat won't be making it through all the layers of stuff between the cpu and the water block fast enough for temps to decrease.

                                                Also, the background music in this one gets a bit grating after a while.

                                                        @manfactuer of copper plate...
                                                        Combine several of those small pipes to spread cooling more.
                                                        Better yet, 1 size larger and flattened, then have a larger combined output.

                                                        @LMG you might wanna find the devices with the largest heat output...
                                                        Simply look for those that become hot according to complaints and reviews.
                                                        Toasty devices would benefit, with that said, this could lead to a run on cheap devices used as stationary high end devices that pair well with water cooling.
                                                        Which in the end would mean, slow wire and tube -less fairly slow and fast as stationary with tube and where needed a power bank.

                                                        Combine it, and as mentioned in some videos...
                                                        It would be nice for on the go and as soon as one sits down with mouse and keyboard and/or gamepad (connected to an external source) one could connect battery bank, cooling and seriously game.

                                                        I could imagine the next gen chipsets of for example nvidia support such a feature on gaming tablets.

                                                        The next nvidia shield?
                                                        Gaming without tubes and wires in HD HDR high frame rates.
                                                        Gaming in UHD/4K with low frame rates and slightly lower colour accuracy.

                                                        Gaming in 4K HDR (10+) with high frame rates and masses of computational power when inserted into a case that enables cooling, charging (speed depending on performance usage and temps), fast connectivity.. .AND no more bottlenecks.
                                                        (Increased number of FALD active?, I mean it is the heat limitations that would then decrease the number of active FALD zones)

                                                        Imagine that....and then allowing users to play with 2 players on a device in high resolutions and high colour spectrum accuracy with high FPS when cooling case is used.

                                                        nVidia, you folks wanted a concept idea back in the days for your devs....
                                                        Here it is! (Just play nice and let others develop tech claim it for open source pls)

                                                        The idea of the Nintendo Wii(iiiiiiii) has worked out great, they earned there spot in the 90's and had there chance to get it back up there like Doom has....

                                                        Now it is time to not just look at the automotive industries as suggested mentioned and conceptually pitched back in the days.
                                                        But in stead, get back into the roots of nVidia, high end gaming....
                                                        And since PC and workstations have gotten so far. Ray tracing and Doom for example.
                                                        Get on and back into Mobile and Modulair design plus.

                                                        A tablet with resolutions and specs better then the Shield 32GB LTE...
                                                        And modulair usage as stationary (or in a case with cooling) AND mobile with a thad better specs while gaming on the go and without tubes and wires.

                                                        For the ultimate experience I would not mind to wear a unit in a bag or backpack.

                                                        Wireless and tubeless Shield Tablet usage scenario...
                                                        120Hz or better FHD(+) HDR (and FALD zones number depending on heat dissipation due to environmental factors) a 6000Mah battery or better.
                                                        Also...when watercooling comes to mobile on a mass scale....battery charging times could be cut to e VERY short time due to per battery cell fast charging capacities....
                                                        DUAL USC C with up to 200W inputs become viable and a serious potential....

                                                        And the dual USB Type C standard could become viable and could include.....
                                                        Yes!, PCI over USB.
                                                        Why?, because PCI 4.0 is around the corner.
                                                        And an updated PCI 3.1 could be the step up towards that for mobile devices (likely mostly phablets and tablets due to require surface area and battery due to bandwidth and fairly power hungry chipsets)

                                                        With that a whole new potential and angle to modulair designing, usage (scenarios), and in the end...
                                                        Imagine modulair usage of devices around the globe....
                                                        Latency is getting lower overall on and between devices.
                                                        And next to that, usage of devices Point to point and peer to peer is getting more and more mainstream.

                                                        Personally, I bulk spend towards high end hardware with the view on long term usage and for mobile I prefer to keep mine powered as much as possible.

                                                        I just miss the available potential out there of having modulair usage possibilities, usability and development overall.

                                                        When I bought an AVR, I missed having the option to upgrade by combining hardware.

                                                        To the creators of PCI, firmware, software and connectors and connectivity overall.....

                                                        Is it not time to create new and next standard that will allow for example pair a 7.1 AVR with a quad (mono) speaker or better audio system and allow upgrading to for example Dolby Atmos.

                                                        Or allowing PCI 4.1 to be integrated with mobile devices, workstations, servers and the many millions of other devices....
                                                        And let a layered inter-communication standard decide and trigger for example the allowed usage scenario's like sharing computational and connectivity availability as well as removing some bottlenecks.

                                                        Downside would be the requirement of a chipset like the Bridges nowadays implemented into CPU's lanes sharing a encryption chip(set) to ensure also the PCI data could be ensured to be safe and encrypted point to point/peer to peer.

                                                        In the end, standards like PCI and having PCI available on more devices globally could again like in its early days make a difference for the environmental impacts as well as allowing the so much missed standards of sharing computational power between devices through high bandwidth links.

                                                        To all, good luck, hoping this could make a positive difference.

                                                        And the end, take the time and choose whisely how and where to implement because over time.
                                                        Usage of one or the other and its implementation could make the difference between removing bottlenecks and moving and shifting them around to other infrastructures...
                                                        In the end, sharing is caring but just shifting bottlenecks to other infrastructures can also break a lot...just as well.
