5.25" Bay TEC Water Chiller
This project is paused until further notice.
The concept is good, but it needs to get less complicated in order to compete against direct die cooling.
Thank you for all the useful comments, and I will see you around.
I've made a few changes in the basic design, put in a 3-3-3 mounting bolt system, made a new flow pattern for the water blocks, and implemented some of my comments answers in the first post. The comments provided where very helpful
Does this maze look a bit better, the flow over the TEC's is improved, but will this take to much pressure to get a decent flow?
This project is entirely based upon the reduction of temperature inside a closed water cooling system.
TECTEC users are a rare breed, there are not allot of them and their set-up's are often revert to as: inefficient, expensive and difficult to make. Well they have a point, compared to air,water, of even phase change cooling, using one TEC at 100% of its designed maximum voltage mounted directly on a high DTP Microprocessor is just inefficient, from a energy and safety standpoint. However as some have people like Ultrasonic2 (muffy) have shown, it is possible to make a relative efficient TEC based water chiller. There are a few drawbacks in using a TEC chiller, versus mounting the TEC directly on top of the CPU, I have found:
- Not as low CPU temperature's,
- Time consuming to make
- They,(except for some) don't fit inside a closed PC case.
But you don't have to worry about condensation, and the amount of electricity it uses will be reduced if you stay above the dew point.
This is where my idea comes in to practice. Is it possible to design a TEC based water chiller that is designed to fit within 2 or 3, 5.25inch (CD drive) bay's, and keeping the project low budget and low energy? I have done allot of reading about TEC's, and in theory my concept could work.
I plan to use 4 TEC's connected parallel and running them at 30-35% voltage to increase efficiency.
As for now I'm calculating the best ratio between: voltage, wattage, amount of TEC's and designing the product itself. How long all of this will take? I don't know but with the help from other more experienced TEC/ WC people it'll figure it out.
I have absolutely no experience with WC (or with TEC for that matter), so any help will be greatly appreciated.
My current list of materials and water cooling equipment.
Pump 1 CPU loop:
Pump 2 TEC loop:
- XSPC X2O 5.25 200 or
- Integrated in pump or
Links are to a Dutch shop where I will probably get my parts.
This loop does not require that the tec's can fully transfer the total amount of heat from the components. They don't even need to be powered on, to use the system, this update will make overall performance it a bit less lower. However because you only have to run the TEC's at high CPU load or high ambient, the overall power consumption is greatly reduced. It does require a second radiator, but only a 120mm one. (Probably) The load on the TEC loop, will be lower than my previous version, because accordantly its transferring less heat. Rev 2.1

How the TEC assembly will look like, for now
PS. don't kill me for my English, I learned to speak it from watching TV.
Thanks to Scarlet Infidel to get me started
