Have some question about peltier cooling.

post #1 of 12
Thread Starter 
What would I need for peltier cooling? Just a peltier pad and power supply? or what? I am running a water cooled loop right now with a 480mm rad with only cpu cooling.

Question that that isn't up to date on, who still sells TEC blocks? Or do you know if any of the commercial blocks could be compatible with a TEC with the addition of a cold plate? thumb.gif

(I didn't think it was worth a new thread for those two questions).

Pretty much have to find someone willing to make one for you. Foxrena on here just released a new design on his block, and Ultrasonic might still be making them if you ask.

If you're super lucky, you may be able to find a used one for sale somewhere...or know of someone with a mill that can make you one if you pay for materials and draw up the design.

Thanks! I'm kicking the idea around of a direct die setup with a Kaby Lake i7 (ie 7700K) at the moment. I don't think DD would be a great option for my 3820 though lol.thumb.gif

You need subzero insulation to start with, liquid tape and eraser in cpu socket areas.You also need cloth or paper to soak up water which stays arround you cpu area.
(if your chilling water then you pump also needs to be insulated, and if its insulated you risk the pump electornic components overheating and diing after months of usage)

Then you need a massive high power single pleiter that goes stright ontop of your cpu which has a wattage ratting of 300+Watts, otherwise use two loops and have one loop to chill peltiers and one loop on the cold side which only has a tiny resviror and has a high water pressure pump that goes into cpu block. You then need to buy non diluted anti freeze and use a 50/50 mixture and your lowest temp before freezing should be at least -20C.
For peltier chilling down water it is only effective if you have zero radators inthe cold side. you also need 500+watts of power usage of peltiers before you actually get more performance over pure water chill. talking about temps during prime 95. Otherwsie it will only be good for making overclock vadilations which you don't full load the cpu.

Its recomended taht you have 1000+Watts of power usage in peltiers if your chilling down water. And the ammounts of raidator you need to chill down the peltiers and the roney you need to build this is not realistic. Thats why you'd want to stay away and use a phase change machine instead.

I had done this before and I only was able to do it cause things get sold cheap in China.

http://www.overclock.net/t/1522183/soundless-devil/680#post_25414081 if you scrool though my build log you will find quite a bit of posts with reguards to my 720W power usage peltier chilled system

For efficenty you get about 25%-30% of power usage converted into cooling, and even less if your delta is high

and you get zero cooling performance if ya think undervolting is efficent and you can get massive delta if you have allot of peltiers . refering to data sheets, 70C delta is only achived with full voltage and high efficenty low voltage operation only gives you 20-35C delta maximum

The ones your looking at with tec calulator, thats only assuming that cpu and cold side and hot side are transfering perfect heat. zero diffrence between cpu and hot side cooling which is never achived in real life.
Also the cold side temp will only be a good representation of a direct die contact setup. Once you chill down water cause water has a high heat capacity 4190 Joules per C change your wasting 4190 watts of cold power per C water temp change

And 400watts high power peltiers are low in avalibility and due to size you can only use one peltier ontop of a cpu and if you want cascade it I doubt it will fit in. You can do a cascade which uses chilled water to chill down a 556w power usage direct die pleiter, and the ammount of cooling you will need to make this work is unrealistic.
And you need a water block to fit those big peltiers which is low in avalibitlity

You could use a massive block of copper or alloy ontop of a cpu then link those to the cold side of the peltiers which is more efficent than chilling water

I guess I will stick to getting my water cooling loop as efficient as possible. Right now I'm cooling a 4690k@4.6 with a 480mm radiator.

take a look at this it might help with getting that loop to run more efficiently.

No matter how efficient you get a traditional water cooling loop to run you are still at the mercy of ambient cooling and ambient cooling limits your overclocking.

You obviously are either curious about peltier cooling or dissatisfied with the cooling you have now, to even ask this question in the first place, so are you going to give up that easy?

There are other options regarding peltier cooling besides just what has been presented here.

I run below ambient chilled water cooling and have been running it over 3 years, I do not have to insulate against moisture as I run above the temperatures that moisture begins forming.

There is a below ambient moisture free temperature range you can operate in, many think moisture starts at the point of going below ambient, but that is not true I run at 15c below ambient.

That allows me to run my CPU a 3770K at 5ghz, 100% rock solid stable and the CPU has not ever been delidded, I could not run the 3770K stable at 5ghz with radiator cooling I could only reach 4.8ghz.

Check this out, you have nothing to loose just looking. smile.gif

You may be running 5ghz stable with peltier chill, but is it prime stable?

My peltier chill that consumes 720w of power does about -2C to 10C durning idle or moderate usage (water temps) and the room temp is about 20c. (about 15-25C below room temp)

Once I do prime this temp jumps up to about 15-20C. with comparison to water cooling, this would only be about 5-10C colder.
We assume your using water cooling with allot of radators so water temps are at room temps.
why assume this? Becasue the ammount of cooling needed for peltiers is massive and if we put these rads for a normal pc it would stay at room temps.

Are the 5-10C temps worth insulating the motherboard? and worth the money and time?
I think it is not, and for the same price you should be able to get a phase change set up which should yeild unmatched performance
