Would adding a pump/hc do anything?
 

My current setup is.
http://24.92.201.229/mods/designs/wc%5Fbefore.bmp.jpg


It has
Maze4-1 226watt
Maze4-1 80watt
Mag3
Single Pass HC 2275
15L res

If I added a:
Mag3
6x6 HC push/pull

Would I get a reasonable difference? Or wasting my time. I run @ 15-20c on both @ 24/7 settings.

Your temps don't mean anything, due to the fact that you're using TEC's. Your water temps do mean something. However, I would imagine that a second heater core would drop your temperatures by quite a bit.

If your water is more than 5C or so over ambient then you'll probably see a good return on an extra HC. You might consider running the pumps in series btw.

It stays 10-15c above room temp. Ouch. How about adding 2 heatercores? I have an extra Impala HC and I can fit a 6x6 in my case. WOuld that be even better? And why in series? I imagine after adding 1-2 more heatercores the flow gets dropped quite a bit.

Also if ran in parallel, would having each pump directly feed water into each block then connecting to go to heatercore 1 in the case be better? :shrug:

:eek: Run them in parallel, and then reconnect before the blocks. You should be able to get your temps down quite a bit.

Before the blocks? Wouldnt it be after? Cant really have 2 pelt in series and make it perform well right?

Series pumps will increase their maximum head capacity (which will give an increase in flow indirectly). Parallel pumps will increase flow directly, but they will tend to fight each other a bit and will suffer from the pressure drop through the system a lot more. For a high pressure drop setup like multiple heatercores and blocks a series arrangement will likely yield better results.

I was talking about two heater cores, I think. RedPhoenix: At the flow rates we deal with, and the heat we deal with, there are not major changes in temperatures ANYWHERE in the loop.
