What Temperatures For Safe Operation of a PETG Loop?

plusgin · March 13, 2018

Any experts have an idea of what kind of liquid temperature should a PETG loop try to aim to stay under (to avoid any potential issues due to heat deforming tubes at all), and what would that translate to for CPU/GPU temps approximately for those without a temperature sensor?

I'm currently running p95 on my overclocked R7 1700 and am reaching 60 deg C, which seems a big high (not that I will be constantly hitting this temp) from what I've heard, would running this 24/7 be safe or is something like a constant 50 on CPU/GPU better in the long term?

Thanks!

60C on your CPU does not mean 60C on the liquid itself.

Usually the liquid is around 40C, though someone with more experience can give you a better answer.

Thanks, you too as well

Yep! So it would be an approx 20 deg difference between components and the liquid temps? That doesn't seem too bad then, since I was starting to near 65 after leaving it for a bit and was worried over time such temps could cause deformations. Any idea of that gap closes once both components are on load?
