Any real ITer would
never exclude anything like that. Yeah I agree, overheating on the CPU normally causes shutdowns/reboots rather than performance issues, but his core temperature is still too high (even though AMD is known for their higher temps, it's still too high). There's no reason to let that go unchecked.
Odds are that it will not improve his game performance, but nonetheless is will prolong the life of his PC.
That said; Obviously, old hardware will cause issues. But from the word "
Phenom" nothing else could be derived. That conclusion would be false solely based on that information. My core is an i7 2600K, which happens to perform about twice as well as an AMD 4130 and that runs MH just fine. The Phenoms are higher up the ladder. We have no specifics on the exact core we're dealing with, so please refrain from just trashing on the whole "Phenom" thing.
The HDD is not per definition the answer either and since the whole world uses mostly 7200rpm disks, even with the SSD becoming more and more common, and I myself use normal 7200rpm disks and have absolutely no issues, you can't even start assuming that he's using 5Krpm disks before you've asked that question.
Your performance is the sum of its parts.
- It could be the CPU:
CPU throttling kicks in if there's overheating taking place, which will directly affect performance on any machine and could lead to complete lock-ups. Your CPU performance would look like this:

- It could be the HDD. Technically a possibility, but since the large majority of the client base of MH and most of the world still runs on 7200RPM, it's less certain that this is a problem.
- It could be RAM. Particles and objects that persist, need to be loaded in memory. A lack of memory (and MH still has a memory leak for now, so DERP) could lead to the mentioned performance issues.
