It fits just fine. I've got one on my a7v133 right now. I'm not as impressed with the fan just because it stopped on me - just about melted down my processor. The case was atleast open and I was just lucky to put my finger on the heatsink and just about got burned. Put my finger in the famous finger eating fan and got it going again. It's been working since. The air coming out of the heatsink feels very cool and the heatsink fills cool to the touch.
