Question Problem with i7-13700k temperatures under load

[TwilightWolfi]

My i7-13700k idles at around 55C package and can reach into the 90s under only moderate load. It often seems to jump even to 100C when I'm doing anything slightly intensive, like playing a high graphical intensity game. The case has never had this problem before, and the pump and fans seem to do a reasonable job cooling the CPU down in any other situations, but might it be because of the very hot ambient temperature in a cramped study? The temperatures have jumped up a lot over the past couple of weeks and it does perform a lot worse on hotter days, but I didn't expect my tower to reach CPU-damaging temperatures. If so, is there anything I can do to ensure better airflow from the radiator exhaust to ensure it can maintain better temperatures?

Once or twice, the pump of the cooler has failed to the point where it flashes the entire case red and I have to turn off the PC and wait for the supercooled cooling liquid to cool down naturally. Could this be a pump issue as well?

When posting a thread of troubleshooting nature, it's customary to include your full system's specs. Please list the specs to your build like so:
CPU:
CPU cooler:
Motherboard:
Ram:
SSD/HDD:
GPU:
PSU:
Chassis:
OS:
Monitor:
include the age of the PSU apart from it's make and model. BIOS version for your motherboard at this moment of time. For the sake of relevance, since you've stated being on an AIO, please mention how you've mounted the radiator to your chassis.

100C out of the high-end Intel 13th and 14th gen chips is the new norm.

Well, you can put your AIO pump and rad fans at 100% when you game. Other than that, there aren't any easy fixes. Going with beefier/better AIO only goes so far that CPU peaks at 95C.

Cooling the 13700K wasn't as challenging as we experienced with the 13900K, largely because it has eight fewer e-cores than the flagship model. We peaked at 85C during stock operation with our 280mm Corsair H115i, and ran in the 95C range during heavily threaded workloads with a 5.5 GHz overclock.

Undervolting is another thing you can try, since with less voltage to the chip - less heat produced as well.

55C idle is quite high and 100C while gaming is extremely high even with a room having high ambient temperature. More information is needed to give good advice.

In addition to the questions listed by Lutfij above:
What is the fan configuration in your case?

Is there a clear path for airflow for the case where it's located?

The front three fans are intake, and the two radiator on the top plus the one on the back are exhaust, so the pressure should be equal inside.

It is in the corner of the room on my desk because there's not really anywhere else for it to go. There's not a huge amount of space in the room it's in, so the suboptimal airflow (putting it mildly, giving the issues) is functionally unavoidable. I have moved it away from the window so it's not being hit by hot midday sun, especially terrible as it's a black case, but it does mean that the hot air hasn't got anywhere to go, and good airflow in the room does miss the hot exhaust air.
