Post Rad Chiller Concept

[Ultrasonic2]

A single loop for the hot and cold sides of the TEC is the biggest FAIL i've heard of for years. it's impossible to get better temps that way. you can only end up with worse temps. due to the fact the TEC uses electricity that gets dumped into the loop as heat. Which means more heat needs to be dissipated by the rad which means higher temps

The whole premise for the single loop idea is floored.
It seems that people are suggesting that if you slow the flow rate down you will see a low temp coming out of the cold side which can then be used to cool the CPU. Resulting in lower CPU temps.

If we exclude the TEC chiller for now. the above will happen if you slow the flow rates down you'll will get lower temps exiting the rads than if you had a high flow rate. but that does not lead to better CPU temps. All it leads to is a greater delta between the hottest and coldest water temps.

If the flow rate is low the water will have more time to remove the heat via the rad for each rotation of the water but the flip side to this is the water has more time to heat up in the CPU so you dont achieve anything the average temp will be the same as if you had the water moving very fast which would result in a very small delta in and out. the reality faster flow would result in lower temps than slow moving water but cause it decrease laminar effect and increases turbulence (not that these factors matter for our argument)


Ambient temp 20c
Now if we add the TEC chiller in the same applies we may be getting say 5c water out the cold side because of the slow flow rate but on the hot side this would have the opposite affect resulting in higher hotside temps say 35c. the average being 20c so there is no point in having the Chiller

Now things are actually worse than that because the TEC chiller uses electricity which gets converted to heat which needs to be dissipated via the rad. More heat to dissipate for the rad means a greater delta from the air to the water temp. Meaning your worse off with the chiller than with it.

It doesn't matter how much heat the TEC's move from one side to the other it's irrelevant.

Single loop Chillers are a fail
