Peculiar slowdown issues

[Artea]

This happens with most games and regardless of the revision I use. Basically, when I start up Dolphin, I'm able to play a game at full 60 fps...until a few minutes later, when it slows down to usually something around 20-40. Even if I lower the resolution to native, the problem still persists and tweaking around with the various graphic options doesn't seem to help either. If I close and restart Dolphin, the same thing happens, only the slowdown occurs much faster (usually within a minute rather than a few minutes).
I suspect the problem is software rather than hardware, because I can play higher resolutions with the same ease as lower ones and the slowdown always occurs regardless of the settings. I'm using a notebook and my energy profile is set to 'maximum performance'. My graphic settings are pretty much the default settings, except for the OpenMP texture decoder which I have enabled (though it doesn't seem to make much of a difference).

Any help would be kindly appreciated.

Your notebook is probably overheating. You should check your temperature

[Artea]

It doesn't get unusually hot when the slowdown occurs (I should've put that in my opening post).

What temperature do you get when it occurs?
And with which games does it happen?

[Artea]

Okay, I used a program to monitor temperature while I was running Dolphin. Anyway, the temp of my GPU when I'm not doing anything is around 70 (celsius). Then when I play on Dolphin, it rises to around 80 and it's then that the slowdown occurs. As for the cores, the idle temperature is 73-74 and when the slowdown starts to occur it's around 88 (the program lists the average of the four cores). Oh, and the game I'm currently playing is Fire Emblem: Path of Radiance. Another game that I was trying to play before was Summoner: A Goddess Reborn and it had similar slowdown issues.

Thoughts?

It's too hot.

Yeah these games are very demanding for your system.
