Neng Tyi SN05 Copper-Based Heatsink Review
Neng Tyi SN05 Copper-Based Heatsink Review
Abstract: Neng Tyi's SN05 heatsink is similar to their massive all-copper SN03 model except that it uses much lighter aluminum fins to reduce the overall weight.

Neng Tyi SN05 Heatsink Perspectives

The Fan:
The Nidec fan is 60mm wide and 15m thick - making it larger than what we normally see. Nidec make very good quality industrial fans, so we were somewhat surprised to see this one on the SN05. The 11-bladed fan rotates at an average of 4700RPM, producing 16CFM. The fan connects to the motherboard via a three-pin connector, and has a lead for RPM monitoring.

Heatsink Top:
If you remove the fan off of the SN05 you get a better ideal of how it is constructed. Anyway, the fan bolts into the fan shroud which funnels air through the 24 0.75mm thick aluminum fins. Each fin about 58mm tall.

Side A:
While this photo is a bit washed out, there are a few interesting things about the SN05 to make note of. First, the copper base has been stamped out and is 5mm thick. The aluminum fins have a small depression on their leading edge to induce turbulence, and the method of construction means that all fins are essentially interlocked into a one-piece unit.

Heatsink Base:
I've never been too keen on the phase change thermal pads, but compared to a base base they are better than nothing. The base has been punched out and is not the best representation of something flat, but where the processor makes contact things are just fine. I would recommend using a high quality thermal compound in lieu of the green Bergquist pad.
