Water loop advice required

[bernard1991]

Hey guys just a quick one
I have a water cooled dell t7400 dual Xeon x5472 processor

The single water loop has three rads configured pump rad cpu rad cpu rad all are 120mm two with Corsair pwm fan and one with stock dell t7400 fan (to stop fans running flat out all the time) inter connected speed control (Scotch lock psu adapter pwm wire on to stock fan pwm wire) airflow feels about the same on all three

1. case internal temperature I approximate to be 21c (assuming 10c difference between graphics card temp at 31c and case temp)

2. Room temp 19c

3. Coolant temp 25-32c (not sure I can trust my reservoir thermometer)

4. CPU temp under load form a game overall 45-56% use with game paused in background (7 days to die running starvation mod) 55-60c

I would like to get it a little cooler if possible

Would it help installing a full copper water block inbetween my water blocks on each cpu and install a splitter which should slow water flow within the water blocks giving increased time to absorb heat into the coolant and also increase the internal surface area on the cpu water blocks?

Software I have recording the cpu temperatures is cpu thermometer
Graphics card temp using msi afterburner
Room temp using by baby monitor lol

Any input would be most helpful

What kinda CPU paste are you using? that can make a big temp difference as well.

It’s one that overclockers uk use on their high end custom build pcs

Thermal grizzly it’s called

you can't get much cooler.
the difference between coolant and GPU under full load will be 10-15C depending on the GPU TDP, die size, TIM and waterblock.
The difference between coolant and CPU under full load will be even greater with same dependencies as above.
the difference between coolant and air can be lowered with more radiator surface and/or higher airflow (faster fans).
so you can get about 5C lower temps which would change nothing.
