Case switched and temperatures increased by 15 degrees.
I swapped cases this afternoon from my old Antec Nine Centurion to a new Fractal Design Focus 2 RGB. The new case looks great overall, but CPU temperatures jumped about 15 degrees—from around 70°C to 85–90°C under load. Before the swap, I hadn’t checked temperatures in the old case, and gaming is usually the most demanding task, so it might not have been the main cause. Online reports suggest this isn’t a typical issue for mid-range cases, which generally stay reasonable. Interestingly, my GPU temps stayed close to what they were in the old setup—around 70°C—and I suspect poor airflow could be impacting both components. The only plausible explanation is that the CPU cooler might not be making proper contact now, or the extra fans in the previous case contributed significantly. My specs show a stock cooler with a 5600G CPU and a 6650 GPU on an MSI B550M-VC Pro WiFi case. The fans are set to 140/120/120/120/200 in the new build.
Additionally, the CPU cooler remained attached to the CPU/motherboard after relocating it into the new case.
Images inside your container, especially around the fan positions, would be useful.
The interior of the case shows the fans running in their standard mode (drawing air). Both fans were spinning when I captured the image since the system was idling. I created a custom fan curve that keeps them idle at 0% speed until reaching 50°C, then increases to full speed at 77 or 78°C.
I identified the problem, but it’s still puzzling how it occurred. It seems one of the four CPU cooler holes on the backplate was partially stripped, preventing full threading and causing poor contact. I haven’t taken it out yet since I assembled the PC, and the thermal paste worked fine when I built it. It appears the threads were damaged either while sitting in the case or during relocation to a new case. Overall, a relatively simple solution eventually worked.
