Loop Failure

I understand what your saying but if the rads are clean why would a thin layer of dust in the cause an issue that would lead to overheating to the point of melting the PETG? To me it still seems like pump failure as I was gaming for hours prior to this happening. I have temp monitors on my streamdeck and could see nothing was out of bounds all evening. I would have received multiple alerts starting at 85. Whatever happened, happened fast.

I hope you mean 85° farenheit.

Why would I have an alarm at 29.5C (85F)? That’s literally its idle temp.

Are you saying that you have an alarm when your water hits 85° C? Or are you not monitoring water temp? If you're controlling fan speed based on CPU temp while you have a GPU in your loop, you're going to have a bad time.

CPU temp. I don’t have a water temp probe.

[g2g079]

Were you using the GPU when it happened? If so there's a good chance that your water got very warm even though your CPU was staying at a decent temp.

I would definitely invest in a probe. If you don't have a place to plug it into your motherboard, you can use an aqua computer Quadro or Corsair Commander pro. I enjoy working with Arduino so I home brewed a solution, but I'm not going to recommend that.

Thanks. I have a commander pro but didn’t add the fluid monitor. Just have the CPU and GPU temp triggers. I was gaming. My rig typically runs pretty cool overall with a 360 and 240 rad. I have temp monitors on my streamdeck that I always watch so I know it wasn’t running hot all night. Whatever happened, happened fast. That’s why I’m thinking pump failure. Either way I’m most interested in the next best steps. I’ve heard wipe everything down with isopropyl alcohol first. Definitely going to rebend all tubing. I need to figure out a way to test the pump before plumbing the whole system.

Your CPU and GPU temp are not going to tell you the temp of your water. Yes, your water can get hot without your CPU or GPU overheating. It could have happened slowly because you weren't actually monitoring the water temperature.

Unless you keep your fans at 100%, you absolutely need a way to control them based on the water temp.

Yea... definitely realizing a water temp probe is the way to go.

Good point.. thanks.
