Hey ho, I just completed my build and now I wonder why the temperature is so high. I have a 360mm radiator and a custom water loop. I do believe these temperatures are way too high. In Windows, I get around 50-57°C, and when I play games like Helldivers or Warhammer, it goes up to around 88-93°C. Ain’t that a bit too high?
What is already clear: there is hardly any air left in the radiator, and I have already renewed the thermal paste, but without success. Furthermore, the water temperature is between 27-34°C in Windows and rises to around 44°C on the CPU cooler while gaming.
Just for context: I previously had the Corsair Obsidian 1000D case, which is known for being huge. In that setup, I had two 480mm radiators and no issues with CPU temperatures (which makes sense). Now I’ve switched to the Hyte Y70, and ever since the change, my temperatures have been much higher. My colleague is using an air cooler and still has better temperatures than me with water cooling.
The pump and radiator are new, while the CPU cooler is one year old. I applied a bit too much thermal paste this time because I tried using a thicker layer yesterday to see if that might be the issue. Before that, I had much less paste on, but there was no improvement in either case.
Specs:
CPU Cooler: Corsair XC7 Elite
Pump: Corsair XD5 Elite
CPU: Ryzen 7 9800x3d
Radiator: Corsair XR7 360mm
Coolant: Corsair XL5 Coolant performance
