CPU usage remains elevated following GPU installation.
CPU usage remains elevated following GPU installation.
The GPU temperature stayed stable during idle at 24-30°C. In League of Legends it reached around 40°C, while in Tomb Rider it was about 60°C under ultra settings.
There are two possible explanations for the situation: 1. The GPU is significantly faster now, shifting the bottleneck to the CPU, which may be operating at its maximum capacity more often than before. 2. The existing cooling system was already inadequate, and the new GPU introduces issues due to its design or size, reducing airflow efficiency. Either way, ensure your cooling solution can support full performance by improving airflow and applying thermal paste. You might need to lower the CPU overclock or even reduce its clock speed if adjustments aren't possible.
Also, I already have thermal paste on my CPU. I just ran out of new ones, so I can't try a different cooler to check if that's the issue. Using toothpaste might help, but I think the airflow is likely the problem. Adding a fan probably won't solve it. Should I change the case or the CPU cooler? I've noticed many people with powerful GPUs like mine have similar issues. I'm worried about buying a new CPU and motherboard because if the airflow is bad, I'd expect the same problem with new parts.
I've played about 10 minutes of Star Wars Jedi: Fallen Order with the case open, just like in the picture. When the system started, the temperature was around 35°C. Once the game began, it climbed to 45°C, and during the first few minutes it stayed steady at 60°C until it rose to 72°C after roughly five minutes. Checking the temperature display shows a slight drop of 2-3 degrees, but now that the PC is still on but not in use, the temp is holding at 37°C. I bought the machine from a local shop, so I'm not very experienced with assembling it. The only work I've done in over five years was cleaning dust, without going deep into the motherboard because I don't want to risk damaging it. I also change the thermal paste on the CPU cooler once a year, usually wiping away as much debris as possible.
It looks quite dusty inside. Blowing the dust away would help. Adjusting cable management could improve airflow around the front fans. I might spot a fan positioned behind the wires.
You're right, I did my best to clean. The main issue is that I can't take off the front panel, making it tough to clean without taking everything off. I've managed to improve the front cleaning, which should help with maintaining a stable 28°C. I've also ordered an additional fan for the CPU cooler and some new thermal paste.
