Do you have an AMD system for comparison? Even AMD systems from that era still works fine today. (Unless you deliberately broke it)

Well, true.

But 5 degrees difference?
You shouldn't be allowing your CPU to hit maximum temperature anyways.

Yes I did have another similarly-old AMD system, but I could not boot it up since 2 years ago. I just felt it was not worth my time troubleshooting the system and then I gave up.

Well, when we talk about longer-term reliability, a difference of several degrees can affect the actual lifetime a lot.

But yes, all depends on how you use your CPU. If you could ensure you never hit the maximum allowed temperatures, both IBM and AMD CPUs should work fine for you.
