Watercooling temperature issue

[Bruno_A]

Hello all,

 

I am running the following setup:

- A Ryzen 5 3600 with an EK-Velocity Nickel waterblock;

- A GTX 1080Ti with an EK Nickel waterblock;

- A 240 Performance Edition radiator;

 

All components are running at stock speeds. On Aida64, my GPU reaches up to 55C under stress, where as my CPU, a much less power-hungry component, reaches over 70C. Watercooled, at stock speeds.

I have tried reapplying thermal paste multiple times, using different levels of "tightness" on the waterblock screws, completely reassembling the loop, etc. My CPU is running hotter than normal, and I am running out of options.

The same issue happened when I had a different motherboard, and a Ryzen 1600. Any ideas?

 

My rig:

You're using a single 240mm rad for both the CPU and GPU?

A single EK rad for a high heat GPU and a CPU?

Is it a EK slim rad? those are trash.

what fans?

Noctua NF-F12 fans. Also, the radiator is a Performance Edition one. It's thicker.

Yes, I am, it should be enough, to be honest.

Depends, are you running 4 fans in push/pull or just two fans?

What are your fan speeds? If you have a thicker radiator in order to keep cooler temps the fans have to be at a higher speed.

Sounds like you don't have enough airflow or you need a bigger rad.

45mm or 60mm? EK has decent 60mm rads but the 45mm is pretty bad.

F12s are meh compared to other fans such as SW3s, ML120s, Gentle Typhoons, Vardars.

Thanks for the input, however the airflow is more than sufficient, I am not running a side panel, or front panel. Also, the radiator is sufficient for both components, and the issue persists even when I only stress test the CPU.

not necessarily. It depends on FPI. The old HWLabs GTS w/ a 30 FPI actually outperformend the large, 60mm thick SR2 with a 9 FPI core, even more so with higher fan speed.
