    People keep emailing us saying “Hey Linus, you should look at Peltier Coolers!” – and I’ve finally given in, so here is a video about why it’s a bad idea.

    Honestly would love to see another manufacturer take a crack at putting a small sterling engine on their heatsink fan.Not for like... amazing cooling or anything... for bragging rights lmao.

    I used to run Switftech Pelt coolers. They didn't catch on because they were expensive and required a lot of prep work to the CPU itself to prevent condensation which is a serious problem for Pelt cooling. You have to insulate against condensation and that can be tough for most people.

    Peltier Coolers were used in the late 90's to early 2000's with the computer modding boom and worked very well for OC purposes. Buy a standalone Peltier that sits right on the CPU, then add a cooler to chill the hot side of the Peltier. If you look at a computerator build where the freeze tray is used to chill a bucket of alcohol, thats then pumped through a water block sitting on a Peltier. It gets stupid freezing temps. We had to add water proofing due to condensation, etc etc etc. most of this was completely impractical but was built just for fun. A favorite was a 400mhz celeron to overclock as these were basically just cheapy pentium 3's. @Linus

    ThunderF00t has a number of very in-depth videos on the subject of thermoelectric coolers and why they are absolute rubbish for applications like this.I cannot recommend his channel highly enough.

    Peltier device should be used based on water-cooling radiator. Which means the peltier devices should be connected after the radiator to achieve sub ambient temperature. So, Linus' 15 yr old engineered refrigerator cooler can retire now. 🤣

    i had a tc cooler back in the day by i think thermaltake. if i remember right it was socket 939 first dual core days.the tc was one of the few coolers that worked. ran around 32c under gaming loads. the biggest problem was the switches to turn on and off the plates.i think thats was one main reason they stopped making them. then core count changed again and became not relevant.i may still have it in a box somewhere lol.

    What was the heatsink he was talking about that was $50 cheaper than the NHU12, and had 2 times the heat pipes?

  • James Wisniewski
    James Wisniewski   1 weeks ago

    I had a cooler like that back when SLOT 1 Intel Pentium II CPU's were around... It had a HUGE TEC pad on it, and then a big ass heatsink and 2 fans too cool that. It worked about the same as if you used just the big ass heatsink. lol

    I was really surprised to see you didn't TEC cool your RED cameras as TEC cooling is awesome for camera sensors.

    you might wanna use a radiator coolant rather than an ordinary water when testing the thermo electric cooler.

    Peltsier facts: 1: Peltsier need heat load to work. (Kinda suprised you did not know that)2: because of 1*, you need to stack Peltsier elements to have reliable efficiency. 3: you can't run it on air. 4: if you run it on water you kinda need a open circuit, (one end of the hoes on the tap, end in the drain)5: the best option is a water cooling system with another cooling medium then water so the heat can be absoreb and relsed faster then water can.

    How do I suggest products for you guys to review? You should definitely check out the ts100, it's a pocket size soldering station, everything you need in a very tiny package, with interchangeable tips. I've had one for about a year now and it's some of the best money I have ever spent. There's an easy access USB port which will let you update the firmware, my can go all the way up to 450x and a boost button.

    Just wondering. Wat would happen if you were to cool the air going into the pc with thermoelectric cells without changing any of the internal cooling? Would it make a difference? I have some peltier cells. Perhaps i do it. Though saying that I don't have a super overclocked beast. Just a amd razen 5 with vega 11 without any thing else. Though I do like to tinker. 😁 And I do enjoy most of your vids.

    The easy way to get it work is to put the thermoelectric cooling on an external radiator of a water cooling system, filled with antifreeze. This way you can have a larger area, up to a few m^2 (something like a room radiator), and up to around 10 kW thermoelectric cooling. But You shouldn't go below dew point, and it isn't energy efficient anyway.

    i have a 'tech' cooler that was built for a 486DX-4 overdrive chip. I also ave the 100Mhz 486DX-4 overdrive chip to go with it. cooling on it didn't wok all that well.

    Hey can you test the cooling performance of the radiator by itself, against the radiator PLUS one of the chiller elements in the same loop? I think thermoelectric cooling may be a better assistant than the sole cooling power

    Seriously, buy a small bar fridge, cut out a hole large enough for your computer and have the face of it exposed while the rest of it is inside keeping the whole dam computer cool.
