Custom loop temp control

916Mick · 17 Jan 2023 at 23:47

Hi,
I'm stating to think that the temperature control for my custom loop is wrong.
At the moment my pump speed is set at 75% and my fans are controlled by CPU core temperature via a curve set in the bios.
During GPU intensive games the gpu gets hot, the whole loop gets warm, but fans stay low due to CPU not getting hot.
I've ordered a Aqua computer temp sensor to fit in the lop to monitor coolant temp.
Can coolant temp be used in the bios to control the fans/pump or will i also need an aqua computer quaddro controller
for control? i'd prefer bios control.
Current rig is :-
Asus Crosshair VII Hero (x470)
Ryzen 7 5800x CPU under EK waterblock
RTX 3080 ti FE With corsair waterblock
360mm radiators (top & bottom) with 3 Lian li DSL 120 on each.
Lian Li 011 dynamic case with EK side Distro Plate

Mobo has plugs for water in, water out & flow but manual is very vague

Any advice or experience appreciated.

Ok, So does it matter where i put the temp sensor in the loop?
i'm lead to believe it doesn't make a huge amount of difference.
Also do i plug sensor into water in or water out on mobo ?

Thank you both for responses.
Just gotta wait for the sensor

Sorry guys but i need more help.
The sensor has arrived and is now fitted and working.
In the BIOS i can change the lower fan control to temp probe, these fans are plugged into CHA-FAN1.
The upper fans are plugged into CPU-FAN but there is no option to change control from CPU to temp probe control.
Can i move the upper fans from CPU to CHAS-FAN2 and somehow get the bios to disregard CPU-FAN
I hope this makes sense

Wow... nearly 100 posts in 10 years..as you can see, if you've got nothing to say, say nothing.

Yeah CPU-OPT will be good coz its next to CPU-FAN
Can the bios be set to ignore CPU-FAN so it doesnt give warning for no fan connected

Ok, so i have disabled CPU fan monitoring in BIOS and fans are now hooked into chas-fan 1 & chas-fan 2.
Fan curve using t-sensor-1 is set to 50% @ 25c 55% @ 30c & 65% @ 35c.
Gaming & stress testing, Max water temp 33c with Cpu @ 68c & Gpu @ 45c with 54c hotspot.
Well pleased.

So a big shout for all help & advice
