    @Linus
    I'm curious. What would happen if you used a Tec cooler with a custom heat sink tower while submerged in mineral oil?

    The fins on the tower should help dissipate the heat into the oil, and the Tec which is great at cooling until it reaches it's capacity should keep the CPU cool. As long as you have a decent radiator system to cool the oil, I see it working well.

    I do work with mineral oil and truly respect it for it's heat conductivity and electrical insulation properties.

    Do note. I am by no means defending Tec's for the average consumer build. I am just thinking of ways around the limitations it has.

            TEC's or Peltier modules need to be pulse width modulated and temp regulated.

                Generally with a TEC set up you use it to chill the water in the loop. Then pop an air cooler on the TEC. I've done it, worked great for me.

                  there is no fixed cold and hot side on a peltier, just swap the connection wires and the sides will change

                      There are a fiew things you should change about this set up, since your using a pid controller anyway you should get the relay working and use more lower powered tec module's that equate to at least twice the wattage rating of the cpu. The more surface area you have to dissipate heat to the hot loop the better and use two closed loop systems with antifreeze in the cooling loop incase you get below freezing temps. The warm side just with the same radiator you used in this video, You are hitting bottle necks because of the active surface area, That and your trying to dissipate too much heat through a poor conductor (tec modules are ceramic) even though your moving heat with electrons. Never put the tec in between the cpu and the heat sink use large water blocks on both sides of the tec modules with a fiew tec modules on each water block to cut down on cost and to get heat to them efficiently, they will force all the heat into the hot side of the water loop and the cold side will pull heat away from the cpu much faster even if kept at ambient temps. If you want to do sub ambient temps (will pull heat much faster) you need to water proof your board and use water tube insulation to stop condensation. but all in all its a great start love the experiment videos. Whole room water cooling loop is my favorite. Keep up the good work.

                            That was a total fail because of the test setup!!!!!
                            On the other hand, it was still an entertaining video.
                            Thanks for trying!

                              A PID controller is basically just a few multiply-and-accumulate operations, and since the system it is controlling has a really slow response time, it could be implemented in very weak hardware (think Arduino Nano). Also, since you're controlling DC voltage, you don't need a solid state relay, all you need is one MOSFET and some way to cool the MOSFET (it could be cooled by the Peltier element itself). Theoretically, you could jerry-rig a tiny microcontroller that fits next to the cooler itself, powered by a 5V pin on the motherboard, and with a thermistor and a resistor, make a relatively precise voltage divider that feeds into an analog pin of the Arduino, so the same chip both measures the temperature and controls the MOSFET. Also, instead of just turning it off when it gets too cold, you can adjust the cooling effort linearly using PWM. That way, the temperature can reach a steady state of your choice instead of oscillating around the setpoint like a refrigerator thermostat.

                                That SSR is triac based, so it's AC ONLY. It will pass DC but it won't turn off.

                                        What if you used the peltier device as the rad instead of directly on the cpu?

                                          That radiator should just be the side of a computer case instead of the glass

                                            Me: noooooooooooooooooooooooooooooooooo 80% rule


                                            Anyways the only place TC cooling could be useful is a super silent rig, but at that point you may as well just go for all passive anyways.

                                                Hi linus,

                                                I think you got to change your approach. Back in the day 2000 -2002, I created a liquid cooling set put for my pc using car cabin heat exchanger, 3 inch 220v fan, windshield washer motor 12v and a Jar of jam as coolant reservoir.

                                                If you want to give another try to this tech then you need to use 3, 100watts paltier sandwiched one over another. One connected to 12v , 5,5v and 3 volts respectively. In that way you will have the ability to reach sub zero temperatures of about -40 degree c.

                                                Now what I want you to do is keep on the the air cooler on the processor. As that’s the efficient way to cool it. Use the paltier cooler with the liquid cooling block along side and connect it to the air cooler so that the heat exchange takes place. Paltier alone will not have enough power to cool off a processor that outputting around 80 - 100watts of heat.

                                                Our main aim here is to get the temperature down so that the processor can be used at higher clock speeds. This is the way I think will work. Let me know what you think.

                                                Cheers

                                                  Did you have a high flow rate for the water cooling? That may have been a factor making it not good at keeping the cpu cool.

The most optimal would be "unvervolting" whole bunch of them and instead having single 500W you'd go 500x1W plates. Would be completely pointless and horrible looking, but hey, it would not be overwhelmed! Also would require 2 cooling loops

You can't put too much current or power to a TEC because the internal Joule heating inside the TEC will overwhelm the cooling power with such a high current, so that the cooling performance of the TEC goes way down. There is an optimal current that needs to flow in the TEC, and you will get a better cooling with a lower power input! A better experiment would be to control the current input to TEC manually, and see when the cooling is best. Good luck!

                                                                        And Kind of like an Eco Instant hot water thing you can get for your house https://www.ecosmartus.com/products

                                                                        And going back to the CPU
                                                                        Ideally you would not have to run too much of a load on the cooling block
                                                                        If your Rad give a lot of "chances" for the water to pass over it
                                                                        So longer pipes that run off the plate and loop back
                                                                        Giving some Fins to the Excess Copper Could also help out here
                                                                        Giving the water time to soak that temperature and exchange it
                                                                        But by the time it hits the end of the loop it should be at what ever you want
                                                                        I am Guessing 15C Would be a very acceptable target.

Air cooler ...they are just different method of transferring the heat from CPU to the radiator ... The radiator is all that matters .... Peltier unit is making things worse ... Remove that crap and directly use that water block on the CPU ...that Giant radiator would improve cooling ... Thermo electric cooling on a actively heat producing system(like a CPU) is theoretically lame idea...

There is one little thing that's fit for the job. Now, pardon my high tech words, and I might confuse a lot of people by saying this, but it's called "The Motherboard". Seriously. You could just use the PWM output to switch the Peltier on and off based on the CPU_FAN header, possibly smoothing it out by using some fuzzy logic by introducing something like Arduino.

You would need 2 water loops. One just for the TEC's Hot Side, and the other being the system loop. The system loop order would be radiator, TEC cold side, CPU. Let the radiators get the water as close to room temp as they can. Then use the TEC to chill it further. You would probaby need to redesign the TEC water block to be much larger than the TEC and give it a long meandering channel back and forth to keep the water in the block as long as possible.

Use the cold side of the tech to cool the water post radiator.
