@@MrIamadon what alot of people don't consider that lower temps from undervolting can also = higher clocks thus also = higher performance such as this.

@@klaasvaak4803 if the thermal medium is large enough it can't be heat soaked especially if you're holding onto it constantly... also if they made it slightly bulkier they could have dual fans on it near the top with a fin stack used in laptops to attempt to move heat off...

you guys should be proud of the quality of your work here. its nice to see the growth from the first things you made.

[@YaruSasaki]

18:55 you could've also just put the cooling tower into the freezer for like 2-3 minutes, or let's say 5 - remember, with thermal expansion your aluminium plate widens, and in that case, so does the gap the tower had to fit in! So your goal was not to cool the plate, but actually to cool the heatsink instead! (since it would've shrunk and therefore fit into the gap much more easily) From mounting bearings onto shafts at work I do know a thing or two about this stuff xD

[@billjoe5794]

So for anyone wondering, aluminum has very low emissivity. That's why the temperatures stayed pretty close despite strapping a big heat sink to it. Not much of the heat was being transfered to the surrounding air. However, aluminum works great when used with forced convection (fan). The rate of thermal transfer to air is significantly higher under those conditions.

[@foldionepapyrus3441]

I'd say very low is being rather harsh on Aluminium, not that you are wrong, I'd just not call it VERY low as out of similarly suitable mechanical properties materials its still pretty good... Also the fins on that cooler gave you lots of surface area which is good for heat transfer, but are far to close together to really cool by creating convection currents in the air - if you want passive cooling you need enough gap between the fin on the heatsink that the hot air rising can actually really pull cool air all the way through the fins (so for the natural way you hold the steam deck these fins were also in a sub optimal orientation).

[@rickstorm4198]

Yep .... Same thing us noticed by guys like me who fabric race cars. You can put 5 aluminum rads and still overheat. Airflow is required be lt via fan or vehicle movement. Copper is def more forgiving

[@Papinak2]

Although you have a point, it's not the cause. The deck thermal throttled to 1700MHz during the first test, with heatsink it ran at 2000MHz.

[@Bushidounohana]

That shop is SICK. Love this “Tool Time”-esque episode. I was Tim the Tool Man grunting throughout, great work, fellas!

[@88Opportunist]

As a proof of concept this is already amazing, With just a little more thought and planning, and perhaps additional thermal know-how, it could be incredible. I would actually buy a product that worked as user-friendly as this was originally envisioned.

[@_deathcry]

That proud "That's ma boy!" smirk on Linus face when Alex makes LTT styled segway to sponsor at 22:38 xD

[@SapioiT]

Honestly, I'd like to see the effects of simply using that fan on the outside of the air vent (it could be literally temporarily taped, to not leave marks), and connect it to the USB port with some soldering onto a pass-through USB extender, so it simply takes away the power (or splits it) and lets you use the rest of the USB port, like normal, just extended a bit outside the device. It could also be used with a 90-degrees USB port extender, in case that's how you want to connect to it.

[@walkinmn]

Yeah pretty much like the smartphone fans they sell for gaming (without the plate some have) , I don't remember how the air flow goes on the inside of the Steamdeck but it could work

[@shelbynorthern5766]

@@walkinmn they had a fan attachment for the xbox 360 that hooked onto the vent and shot the air forwards

[@SapioiT]

@@walkinmn At the very least, running the heatsinks in double pull configuration would be better than running it in single pull configuration. Because each fan has to do less work if working together, than if only one is working.

So true. He also walks linus through the long route of doing something, full well knowing that Linus will suggest the short and easy route. Letting it be his idea that saves time and energy.

[@justsomeperson5110]

I was almost disappointed. Things were going well. The heatsink mount looked almost like a professional product. There was an alarmingly minimal level of jank. OMG! Say it ain't so! But then they zip-tied a Noctua fan to the heatsink. And ran an external power supply with cables everywhere. Oh thank goodness! We're back to the chaos that is Linus. Some joking aside though, so how long do you think we'll have to wait before someone from China rips off this idea and mass markets a kit? And can it come with a built-in USB hub?

[@rapiddu6482]

I don't think you even need usb hub. Steam deck's own charging port will support the fan. Usb charging ports easily do 5w this supports SSD so it might be something like 7.5-10w even. So no problem

[@justsomeperson5110]

@@rapiddu6482 "Steam deck's own charging port will support the fan." No, not a USB hub to power the fan. I don't think the fan needs external power either. I mean a USB hub because the Steam Deck NEEDS MORE USB PORTS!!! LOL I swear, why Valve thought skimping on USB ports was a good idea, I'll never know. So while adding a big honkin' cooler to the back to turn it into the "Vapour Porch", why not include a USB hub that attaches to the back as well? The fingers on your other hand need something unfortunate to accidentally brush against too. Symmetry! LOL

id like to see someone make a replacement back for the steamdeck that gives some extra room internally for a proper heatsink and at least a 2nd fan to help move air in the tiny case. its already kinda thick on the sides and to use some of that void in the middle would make a LOT of sense to both shut the normal fan up and to make the whole system run better.
