That temperature seems perfectly normal. As has been pointed out multiple times, load temperatures in the 70s are not much of a concern for modern CPUs, and it's not surprising to see a high-power processor like a 10700K hitting those temperatures on a tower cooler. And if the CPU fan slows down at idle, temperatures around the 50s might not be unexpected either, and almost certainly won't be harmful to the processor, as they are not anywhere remotely close to its thermal limits.Ok ill try to remove the front panel and see if its better then. But nonetheless I dont think it's normal that I hit 77 while playing cp2077 altough the front panel is closed.
Again, modern CPUs tend to be quite durable and have failsafes in place that make CPU failures extremely uncommon. If a piece of hardware ever fails in your system, it's most likely going to be something other than the CPU. And you are probably much more likely to damage something while reapplying thermal paste and reinstalling components than you are from those kinds of temperatures. I think you are being overly concerned about something that isn't actually an issue.
