Noctua NH-U12P CPU Heatsink with/ Additional Fan

Noctua NH-U12P

Today up for a review is the NH-U12P CPU Heatsink that Noctua kindly sent to TechwareLabs. The first thing that came to my mind after taking the first look at this heatsink is that it is frikkin' huge. Yes, ladies and gentlemen that is a 120 mm fan that will be strapped onto the heatsink spinning at the speeds of up to 1300 RPM. As I was pondering about what kind of funky tests I should run on this particular heatsink, two questions came to mind.

  1. Why did Noctua bother to send us an extra fan?
  2. How would this heatsink perform in comparison to the stock CPU cooler from Intel?

These and other mysteries regarding will be uncovered later in the review. As for now, here are the essentials.

    As you can see this is a rather heavy and rather large heatsink. As such you should consider if it will fit into your existing setup. SFF cases are easily a no-go for this heatsink.
