I think you haven't try to push your CPU hard enough to feel the difference.

I believe the difference will be more pronounced if you're running higher clockspeed around 4.2ghz .

Now your temp is around 40~50~ only.

Push till getting 80~90 C for air cooling. Then AIO will give you the temp difference.

I myself prefer AIO because I don't like too much weight of the heatsink putting burden on my motherboard.
