        I was thinking about a thermoelectric cooled water reservoir to use for spraying chilled water on the intercooler on my car. It would only mist when a certain boost level was achieved.

            Heating water with a Peltier may be a bad financial idea, but it certainly is not a bad thermodynamic idea. Go back to school!

                Why take a large power hungry peltier to the CPU, when you could use a lesser one to cool the water reservoir of a water cooled system. Also easier to test. Or, use them to generate power from waste heat and power moar RGB - bwahahahaha.

                  It's MAGIC. It was invented by someone in Florida who wanted to bring cheap, free CPU cooling to the masses, and who was of course assassinated by Big Air and Big Water. Stop pandering to the man, Linus.

                    I was researching peltier chips on CPUs and stumbled across an interesting comment (not sure if it was this video or another). Someone suggested using a peltier chip in conjunction with a water cooling system. Instead of applying the peltier to the CPU, you put it on the water reservoir to keep that cool. However, hearing about how peltiers use a lot of energy, I decided to look up ways to control the voltage to a peltier. Apparently, you can't regulate the voltage. But, you could turn it on and off with a PID controller. The PID would monitor the water in the reservoir to make sure it maintained a constant degree. If it went too high, the peltier would kick in and cool the water back down to the optimum temperature before getting turned off again.

                      "Ya, Andy just left his water bottle here." Turns it around and a big, tape "A" is on the other side.

                          I wonder if you could use 2 of these peltier coolers in series & direct all the heat to one & all the cool to another ?

                            Would the results be different with a lower wattage cpu? Like would this cool a 65 watt cpu better than the traditional radiator would?

                                  You should build an excessively ridiculous liquid hydrogen cooling loop to see some truly insane OC numbers. Since liquid hydrogen has a specific heat that is like 3x that of water, on top of being quite chilly to begin with. It would fall under "Bad Cooling Ideas" not because of poor performance, but really low performance/watt. I'd really like to see all of those extreme results.

                                    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 deliver

                                                      Also, 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.

                                                                              • ʜ̲̅ᴀ̲̅ɴ̲̅ᴋ̲̅ ʙ̲̅ɪ̲̅ᴢ̲̅ᴢ̲̅ᴏ̲̅5̲̅
