"As far as performance goes, things got a little toasty in my testing, which was expected. But my testing is really outside the boundaries of what this cooler would normally be subjected. My testing did show that this little cooler that can almost fit in the palm of your hand still kept an overclocked 4770K a few degrees below 100 °C. While that is a bit on the high side, I hesitate to list the cooling performance as a Con, because if you use the cooler within the design intention, which is small form factor cases and HTPC environments, then you will have no problems. It does a fine job of cooling. If you try to cool an overclocked gaming system, well, Noctua has a variety of coolers that are better choices.”
