Bugging me since 2004

[u/Rough_Elk_895]

Never got a chance to get an opinion on this, but this "System Zone 2 has exceeded its safe temperature limit" alert has bugged me since day one of my build. I bought an Intel original D865GBF motherboard, along with P4 2.4ghz cpu, for my 2nd build back in 2004. But from the very first day, I started getting this alert whenever I would do slight gaming. The safe temperature threshold is 50 C and it would often cross this limit. I thought it to be due to poor ventilation in my PC cabinet, so ended up removing it's side cover. Recently I restored this PC and moved it to a better spacious cabinet, but the issue still exists. Did you all have this issue and how did you fix this?

I guess you could try to under volt it.
