That's a testament to power management/throttling in modern CPUs, we're long beyond the days of K6's and Cyrixes cooking themselves to death because of lack of built-in thermal management.

[@volvo09]

Yes, it has come a LONG way.

[@HappyBeezerStudios]

While throttling is a bit more recent, even the K7 chips would turn off when getting too hot.

[@Drewtheelder]

A K6 was my first-ever build a long long time ago.

[@volvo09]

@@HappyBeezerStudios i can't recall exactly but I remember the first open die athlons being "targeted" for no thermal protection, or bad thermal protection. I believe outlets were yanking coolers off cpu's and sometimes the chip would die instead of turning off... With a fan failure it would survive since the temp rise was gradual, but abusing the chip with a sudden no cooler situation would kill them (or some of them). This was back in my dialup days reading overclocking and CPU stuff, I never tested it for myself, but I remember some outlet covering it.

I played around with peltiers for cooling the print bed of a homemade chocolate printer. I had 2 peltiers stacked on top of each other, with a water-cooling block cooling the stack off. I was able to get the aluminum print bed down to 20f. But, double-stacking peltiers is super inefficient, power wise...which is exactly why you should try a double-stack with water cooling! Most peltiers go up to 12 volts, so it's easy enough to use the 12v rail from a PC power supply to run them.

[@Unassuming_Troll]

The reason the phone cooler wasn't working as expected isn't because it's small, but because peltier coolers need to have a "thermal mass" much like the metal plate you'd attach to your iphone in order to buffer and move the heat to the other side. Attaching a peltier directly to a cpu causes the peltier to heat up along side the cpu greatly decreasing its performance while increasing the amount of electricity is needed to pump heat to the other side, to remedy this, you'll need to attach a "thicc" slab of metal between the cpu and the cold side of the peltier to serve as the "thermal mass".

Honestly man, you can run a 5300G on a literal slice of metal, and it won't do anything except drop the clocks and power-limit to keep it running. Newer Ryzen CPU's are nearly impossible to thermally harm unless you tweak things in the BIOS. Even the 7000 series that tends to run warm, you can cool a 7950X with a Wraith Stealth and it'll run fine, just at a lower clock-speed (not recommended unless you're Dawid, just making the point).

[@andrewshobbybasement]

As someone who's played around with peltiers before, the main issue is that they don't get cold enough to negate the heat that they produce. As such, they are only useful in very specific circumstances and it's generally more efficient to just cut out the middleman and make direct contact with the heatsink.

[@ewasteredux]

I really think you should try the peltier coolers in more detail. I have built several projects using them and they are very neat (as long as they can dissipate the heat THEY generate on the opposing side). eBay has some pseudo refrigeration units using them that are interesting if not slightly comical. Depending on wattage, you can use a motor speed controller to adjust the power going to the peltier modules if you choose to make them adjustable.

[@volvo09]

Any modern peltier cooler worth it's salt monitors ambient air temp to not over cool the CPU. Past ambient. But modern CPU's create too much heat for a peltier to handle and cool past ambient while under load anyways.... It's idle when you run into condensation trouble.

[@Xorthis]

I experimented with peltier coolers back in the 2000s. They 'should' be awesome, and 'active cooling' sounds amazing, but they have a fundamental flaw. They move heat through them by using power. If there's no power applied, or more heat than the power you use with them, they turn into an insulator. Think of it like a doorman. If the doorman is given a donut (power), he will pull a person waiting in line through the door with a ton of force, very quickly. But if there's more people than donuts, he won't let enough people through and the line gets massive. So, lets say you want to cool your 90W CPU. Your peltier needs to be consuming at least 90W to get the heat away from the CPU. On a 5v 2.4A USB connection, that a maximum of 12W cooling available... and that's why your CPU was power limiting itself to not go much over 20W once the thermal capacity of the cooler was reached. (Due to conduction, some heat was passively making it's way to the copper cooling fins. If you wanted to use a 200W CPU, it may be possible, but you're going to need a 17A peltier on 12v to do that... and they cost around $300! Back to my experiments with peltier coolers, they were all incredibly bad. I was shocked at how poorly they performed, despite having a bigger thermal mass than my old cooler. This is why you never see peltier coolers used for PC cooling these days. Oh, and the other issue? The cold plate can get too cold if it's not adjusting power to match the CPU's draw, producing condensation. And you don't want condensation on your CPU cold plate...

Hi :) can you do this again but this time with an ROG Ally. You're probably the only one crazy enough to do it. The Ally backplate can be replaced with the HandheldDiy clear back case that actually has a thin metal fin that dissipates the heat towards the back vents, and the metal plate is directly touching the CPU and APU heatsink, so technically, you can cut out the back plastic part of the case and expose the thin metal plate and you can mount a tec cooler like this or maybe the new Redmagic cooler one, since its size fits almost exactly as the size of the plate and you can attach it magnetically. it's a longshot but would be really nice to see you do it, I have everything here but I'm too afraid to do it since it's never been done before, but in theory, it would definitely work.

[@Adamsgotgame]

[@Starscreamious]

Dawid, 20 or so years ago people were using peltier (TEC) coolers but it seems that some knowledge has been lost to time. IIRC back then you were told to only run the TEC at 50% power or lower because if you ran it at higher than that you had more waste heat than you could deal with and the efficiency of the cooling went into the toilet. Every single youtube I've watched (Steve Bruke, Linus Sebastian, Wendell) has failed to mention this when they played with TEC's. So....if you're going to try it can you try buying an overspecced one and running it at 50%? My curiosity thanks you in advance.

I suspect this would be dramatically more effective if the thermo-electric unit was actually fixed to the cold plate with a mount instead of "loosely" applied with a VERY thick layer of thermal paste OR if you applied the thermo-electric unit more directly to the CPU with light mounting pressure. I think Linus has done some direct mounting to CPUs with these units before. All that being said? This is probably only made to handle like... 10w? so keeping 25-35w from exploding is... impressive.
