I've been suddenly getting throttling on the Iris Pro graphics on macbook pro on both osx and bootcamp. The gpu temperature goes up to 100 C Celsius when doing anything graphics intensive, even if its just for a little while. I checked msi afterburner on bootcamp and the GPU core is underclocking. I'm not getting any cpu throttling though. What seems to be the problem? I opened the bottom hatch on the macbook and I didn't see any dust or anything that could be interfering with performance.
