Japan PS2 feels warm, I'm worried

[Supercake]

Hey guys. Well, I just got my JPN PS2 today, and it feels sorta warm after I finished playing, wasn't even that long, maybe 15 minutes. It's not HOT, but kinda warm, I'm just wondering if this is a big deal. Is it something to do with the voltage, anything like that? Case it matters, it's model: SCPH-75000 Satin Silver.

Don't be, the PStwo will always feel warm just due to its smaller size (even to where it seems like it's overheating), but it's normal...
