The new low-profile Noctua NH-L9i CPU cooler review
Looking at the review it's slighly better than a stock cooler and a little louder....Is pretty small tho.
Excited because it's a Noctua?
No reason to buy it unless you just love the noctua name. It's no better than this Phanteks, which is half the price lol.
It's probably due to the design. Let me explain.
The Noctua uses a mere two heatpipes, which won't carry much heat. The Phanteks uses fins directly soldered onto the base.
Now heatpipes are great for moving heat a distance, as temperatures will equalize along the entire pipe. Fins directly connected to the base will get cooler (less heat transferred) to the tips of the fins.
This means on a big/tall heatsink you absolutely need heatpipes because otherwise not enough heat would be transferred.
On a small heatsinks either heatpipes or direct connection would work.
Then it comes down to how many heatpipes, and two is not enough for a hot CPU.
