    Vincero Watches' 5th-anniversary sale is on now at https://vincerowatches.com/techsale

    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.

    Nice Vincero watches!Great for using in a blender or shredder.Btw, the Germans used peltier elements on their u-boats to produce electricity from heat difference between the water and the u-boat itself.That way it's thermal footprint was lower/smaller, making it harder to detect by enemies and it didn't need to go to surface for replacing batteries.

    Ok so now you need to make a block to cool another block to see if two loops combine can be magic, or would it equal two sets of radiators on the same loop?

    If power was no object you could end up with a super cool and quiet rig if you added enough of them

    Thermoelectric cooling will never be worth it. You have to not only get rid of the heat of the CPU, but you also have to get rid of the heat the Peltier is adding to the system before you see any measurable benefits. If you use a 500W Peltier, then you have to get rid of that 500W too.

    Should left the radiator hooked up while doing the peltier loop and seen what the results were.

    have you tried to slow down the flow rate? maybe giving the chillers more time to cool the water may help? i understand it will also give the CPU more time to heat the water up but maybe it will make a difference over all..

    Is there any benefit of cooling a cpu and gpu below ambient say maybe 10 degrees celsius under overclocked load instead of 30 to 80 or whatever above ambient degrees celsius?Maybe longer life or better efficiency? I also don’t see the tec’s as stand alone coolers, they are more inefficient than radiators above room temperature, yes, but because radiators cannot cool to or below room temperature, tec’s are therefore more efficient there. Just not sure if there is a benefit. Also not sure if a better build with tec’s is to use the water cooling blocks on top of the tec’s and cpu to water cool the peltier, keep the size and noise down, as well as get the cpu below room temperature or to put the tec at the end of a radiator loop with some 6 heat pipe tower heat sinks where the tec chills room temp water from the radiator below ambient before it passes through the cpu and gpu and even to cram a peltier and water block inbetween the gpu and cpu to flash chill the water between the systems and to make use of the small size of the modules. Another system is to carry a double stack radiator with one water loop for cooling peltiers and another loop for bringing water to room temp with maybe an electric valve switch to either go below ambient or turn off the peltier and route water from the peltier cooling loop to the central loop when overclocking. Long story short, anyone investing in water cooling isn’t exactly a budget builder and will pay a few extra buckaroos for space saving, lower noise, and looking for whatever air cooling cannot deliverAlso, get yourself a krimping kit, like cheap dupont 2.54mm connectors if soldering is not your thing :p

    If one tower is the hot side and the other one is the cold size then the fan must be put in place so it pulls from the cold side and pushes to the hot side

    I am absolutely certain that the thermoelectric cooler will run perfectly on AMD processors. After all, they consume a great deal less power and run much cooler than comparable Intel parts. If I had to live and work in Antarctica, I would use only Intel. They are very efficient room heaters, especially the i9 9900K.

    we just need a miniature black hole to suck all the excess heat.

    2 questions. Does anyone know what type of laptop Alex is using, and does anyone know the specs of the rig they are testing the cooler on?

    Perhaps it's not mature technology? WTF, it was invented in 1838!

    Have a try to put the peltier after a radiator. That must work better. (Since that means we simply have extra cooling)

  • Aleksandras Fedotovas

    because its too expensive to run..if you can manage to run it at all XD its still not mature enough XD

    What if you use the 2 aquarium coolers in line with a radiator to cool the water coming out the cold side of the radiator then run it to the cold side of the cpu block and so on

    Use Hailea HC-500A or higher and get rid of the rad and fans?.

    I had a Titan Amanda TEC cooler back in the Core 2 Duo days and it worked pretty well, was just quite power hungry.

    the peltier waterblock is very inefficient. it is exchanging heat in a very small area. this test was very bad done.

  • Billy Wang

    Better to overheat the CPU and generate some electricity back from the temp difference lol

    I seem to remember removing peltier devices from old macs, I think they were 6100's, 7100's, 8100's, or 7500's. I can't remember if they were stock or not either. These were in early mid 90's models. (LOL - When Linus was about 10) Somewhere I still have the plates packed in storage...
