The Epic Games Launcher appears to be continuously running some sort of relatively demanding process in the background, when the spike in CPU temp occurs.
Even though Epic Games store has been giving away free PC games for this Holiday season, some gamers have been experiencing issues with the Epic Games Launcher client. There have been several reports that the Epic Games Launcher has been found to increase the temperature of some AMD Ryzen and Intel processors.
This is making some CPUs to run hotter even without any game running, as reported by multiple users on Reddit, and also tested and verified by Hot Hardware as well.
One Reddit user @Neoncarbon noticed that his AMD Ryzen 7 5800X CPU idle temps dropped from 50C to 37C when he closed the Epic Games Store’s app/client. The EGL application appears to be using some CPU resources even when it is running in the background. At least that’s what is being reported right now.
Though, it should be noted that not all AMD Ryzen owners have been experiencing this issue, so it may not be widespread as reported on Reddit. But some INTEL CPU owners have also observed a similar behavior with the EGL app.
Some Ryzen CPUs may run up to 20C hotter with the EGL client, and that’s without any game running. As mentioned before, the launcher appears to increase the CPU usage on certain threads which in turn is affecting the temperature of the whole processor package.
As reported by Hot Hardware, “Anyone that has the Epic Games launcher running in the background has higher CPU temps and usage, even while idle on the desktop”.
As you can see from the screenshots posted by Hot Hardware’s testing, the AMD Ryzen 9 5950X CPU shows 34.28C temp value when the EGL app is not running (shown on left side), and the temp shoots to 56.78C value when the app is running (on right).
For what it’s worth, Hot Hardware was running a liquid-cooled AMD Ryzen 9 5950X CPU. Even in the idle desktop mode, Hot hardware noticed that CPU temps were around 53C when the Epic Games launcher was running, and there was 2% CPU utilization from the app itself on this 16-core AMD Zen 3 processor.
