Liquid Temperature

[Nick980]

Hi, 

 

First post, whoop!

 

Currently using EK cryo coolant but guess this would apply to any coolant, what do people recommend as a safe temperature for the coolant in your run to be at? Currently mines around 20c-25c idle and around 45c-55c when I've been gaming for awhile. Not sure if that temp is acceptable or if I need to crank the radiator fans up. Running a Ryzen 3600 and Vega 64 in a loop with 2 360rads and corsair ml120 fans running at around 1200rpm

For a custom loop 

Seems good to me

Acrylic should hold for up to 80c.  All other materials should be 100% okay.

 

During my loop building processes on AliExpress I have noted many sellers maintain not to run a loop at 50c+ liquid temperature when dealing with their acrylic reservoirs.  Obviously these are going to be using the cheapest possible bonding adhesives and may be the actual issue.

Check the temperature requirements of your pump. I think mine is fine up to 65C, but I run at up to around 35C-38C under load for my coolant.

Hello and welcome.

 

I would say that the coolant is fine up to 60 degrees C because that is (at least according EK) maximum temperature for the pump.

 

I have a setup similar to yours (2x360mm rads) and my liquid temperature range between 25C and 38C, but perhaps the measurement also depends on the sensor used.

The fans on my radiators run at 800 RPM until the liquid reaches 30C. After that, they ramp up in a linear manner up to 1200RPM at 40C.

 

That said, although is convenient to use the liquid temperature to set up a less spiky fan-curve, in my opinion the cooling performance should be assessed by watching the component temperature and not the fluid temperature.
