second radiator
 

would adding a second radiator help my temps? its going to be a passive so no fans. my pump is the mcp600 and i already have an actively cooled procore. if so how should i run it? pump->cpu block->gpu block->procore->second rad->res->pump?

What are you water temps comapred to ambient?

my cpu temp is 32 and my case temp is 35.

:-) WATER temps :)

As a second radiator will only lower your water temps, we need to know your current water temps. A passive rad after an active rad will lower your temps by only 0.5 degrees or so.
(unless it is real large, or your temps are real high)

Why not place a 12 cm fan on 7v on there? this will help a lot, and can lower your temps with 2 or 3 degrees. (depending on your current water temp and size of the additional radiator)

Thank you for two numbers I didn't ask for...
Now how about water and ambient temps? :p

i don't know my water temps. my ambient temps are around 25C. case temp is usually 5-10C higher than this.
