Quite an interesting design, wonder how it would do with a 100CFM fan.. Although it doesn't look like fan speed has a huge impact on temps which is a good thing.
Neat idea but I don't have a 100CFM fan though. As soon as I'm done with what I have on there now I was going to put the NV120 cooler back on but with out the fan. I'm curious to see how it will do as a passive cooler.
In general, heats-pipes are not air-side limited. So, putting more CFM through them isn't going to buy any more performance.
For a high ended heat-pipe, each pipe would need a unique style of plates and air-centers to increase the performance. Plus a unique shape to overcome the vertical performance hit.
In this review, the heat-pipes were placed in a tower configuration. This allowed gravity to have some bearing on the internal fluid. Thus, only 50% of the heat-pipe was primarily functional overall in this test. The remainder of the heat-pipe lower than the CPU had about 30~40 percent performance hit and more than likely flooded out.
If this test was done on a horizontal PC bench test, the result would have been even better. However, most of the readers here own systems having the CPU in a vertical position.
In time, the next generation of heat-pipes will be U-channel shaped and position orientated. This in turn not only helps the performance, but reduces the overall footprint of the cooler. A win-win of a product. The key is for lower cost production to bring it into the retail market which is extremely competitive for a the amount of DIY'ers or people who venture into opening up their computer cases.
Certainly, this reviewed product should do well having 4 pipes vs. 3 or less. Doing the passive cooling would be neat to add to this review. It will take some careful time ramping from idle up to bearable loads. If the cooler performs well under load in a passive mode compared to the Intel reference cooler, then this would help when the fan dies out in the length of used time.
