I don't think it is overheating the GPU temp reaches around 50-60 on the main menu of Punchout yet the fps drop. I mean I havent even started playing the game yet

This isn't true at all. My desktop i3 will reach 65c in Dolphin, possibly pushing almost 70 in a hot room. Starting a recent (AVX enabled) version of Prime95 puts it to scary temps (80-90) almost immediately.
it depends on what game you're playing crumpet.

Really? Which title do you think will cause a higher CPU temperature than Prime95? I'll test it and report back.

Intel Stock cooler ? Do you apply thermal compound properly ? I can't imagine a Haswell i3 can reach 80 degree Celsius full load .
80 degree Celsius is normal for mobile CPUs but it's not normal for desktop CPU
Desktop CPU can't withstand high temp like mobile CPU

The @OP uses a laptop which contains both CPU and GPU .
CPU and GPU are soldered on the same heatsink . Even if they are separated , there is limited space to dissipate the heat . Dolphin uses both CPU and GPU while Prime95 only uses CPU...

Yep, I redid the thermal paste a few times, then I finally googled it. Apparently it is normal for torture tests/power viruses like Prime95 w/AVX to run Haswell chips extremely hot with the stock cooler. It doesn't reach 80c under any real-world load, it doesn't even quite hit 70. It's usually more like 65.

True- I didn't think about that. I was considering CPU loads only.
Dolphin is not anywhere near as heavy as prime95 from my experience. Temps barely go above 50 for me in Dolphin and any torture/stress test will push it to atleast 64-65. Prime95 might even make it go higher than that.
If you see the framerate drop in the menu, it's not actually microstutter. Microstutter would be the game saying 30/60 or 60/60 but the framerate looks like ass.

I have a passively cooled desktop/HTPC setup with my Intel HD 4670S (65W), including some fancy heatpipes and properly applied thermal paste. The cooling sucks, as you can imagine, but I have not witnessed any instability while playing with Dolphin, nor have I had any instability when runnin Prime95 for reasonable times.
The temp is 46-50 Celcius when idling.
With Prime95 the temperature reacheas a plateau at 89-91 Celcius after 10 minutes or so. This is the highest I can get. I see no throttling.
With Dolphin, the temp resides at 75-85 Celcius. So the thermal burden seems a LOT lower when two cores are utilized with Dolphin and GPU is doing as much as it can, compared to four core CPU only stress test (Prime95). And no, I don't see any fluctuations in Dolphins framerate, which would hint that overheating would cripple the performance.
I think Haswell is (desktop incl) designed to take higher temps. But if the frame rate really drops after some suspicious time, then of course it's possible that the CPU is overheating.
Not sure about the adjacent components inside my HTPC, though, hopefully they can take the temperature for some years. At least I don't need to run Prime95 just for fun, after I've already seen the boundaries I'm dealing with.
EDIT: But this is mainly Off Topic, sorry about that. About the microstuttering in the topic, personally I've seen the microstuttering happening only when Vsync is not working as it should. Plus with shader generation briefly.
