I'm using an older Dell Inspiron 3583 laptop mainly for casual gaming and as a home theater PC (HTPC). After my fan died, I replaced it, and now I'm monitoring the CPU temperatures with Core Temp. However, I notice that during video playback or gaming, the CPU sometimes spikes into the high 90s Celsius, and I see an exclamation mark on Core Temp. I've already reapplied thermal paste between the CPU and the heat pipe, but the issue persists. Is it possible that the heat pipe is malfunctioning? Could these readings be inaccurate? Am I overreacting or should I be concerned? Just to note, I'm not experiencing any performance issues, and it seems that Speedfan doesn't detect these high temperature spikes, so they might be brief if they are real.

It sounds like a good idea to double-check your temperature readings. I recommend using Libre Hardware Monitor as a replacement for Open Hardware Monitor to get a more accurate reading. Sometimes software can report temps inconsistently, so it's worth it to try a different tool.
It's pretty common for laptops to run close to their thermal limits, especially under load. Many are designed to not ramp up the fans until they're within about 10°C of max temp, which can lead to some high spikes. Even if it seems concerning, it might just be normal behavior for your laptop. However, if you’d feel better, you could look into adjusting fan settings to keep things cooler during gaming.
So you think it's normal for it to act this way? I would prefer if the fan could run more often, but I’m hesitant to mess with those settings.
I'm getting similar readings with HWinfo. I’ll download Libre tonight to see if there's a difference.
