cakesg Posted February 27, 2020 Share Posted February 27, 2020 What happens if the coolant goes above 60c? I ran a stress test overnight and the fans turned off sometime. The coolant temp was around ~67c when I woke up. Will this damage my pump(as I read the maximum operating temperature is 60c) or my acrylic tubing?

acemaninwa871 Posted February 29, 2020 Share Posted February 29, 2020 I at least wanted to respond. As long as the pump still works, I'd say you are ok. But if I were you I would expect a reduced pump life. The acrylic pipe should be fine. Link to comment Share on other sites More sharing options...
c-attack Posted February 29, 2020 Share Posted February 29, 2020 Not the pump metal, plastic, or nylon components that have heat thresholds far above that level. Most manufacturers list a 50-60C maximum, but this has more to do with effective use. Your coolant temp is the lowest possible CPU temp with zero volts, so if you are idling at 60C, you will slam into the throttle zone anytime you apply load. I am somewhat surprised your PC did not shutdown or perhaps it did and you meant the coolant was still 60 something Celsius when you booted back up. That is possible since the heat dissipation will be very slow with everything off. Link to comment Share on other sites More sharing options...

c-attack Posted February 29, 2020 Share Posted February 29, 2020 Possibly, but then this has been the guideline for much longer than PETG has been in use in water cooling. Hopefully no one is using the lower temp threshold PETG to make tubing, like the variety you would use for 3D printing. Link to comment Share on other sites More sharing options...
