Re: flow rate and temps
Yes, it's simple Thermodynamics... If it's possible to be simple.
You slow down your flow, there for the fluid is sitting long in the hot zone and getting overall hotter, so the delta T, difference in temp is less,, so it absorbs less.
Your setup also can cause issuyes.. before, the heat woul be expeled right after its added, Your rad is your best cooling, then still have more time to goto room temp, and dumped into a larger mass, furher reducing the temp.
Now, you have the hottest fluid dumpuing into your larget mass, thus raising your initial Temp, So really, your rad is cooling not hot fluid, closer to room temp, and it doesn't do that well.
Go back to your old settup. and it should work better.
