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.

And the results are in and..... they aren't too hot. Or, more accurately, they are way too hot. Despite its large size, and seemingly effective design the SN05 comes in last in this set of reference coolers.This just goes to show you that if the heatsink has copper it doesn't necessarily mean it will be a superior cooling device.

In the case of the SN05 my hunches would lead me to guess that there is a problem with the thermal bond between the aluminum fins and the copper base - either too little thermal glue has been use, or the matting surfaces are not adequately flat. In any case, the SN05 looks meaner than its bit really is.

13 Neng Tyi SN05 24.5 40.5

One of the great things about numbers is they never lie, and in this case there isn't much we can say to make a 40 degree result on the small copper die template look anywhere near rosy.

But if you care to turn your attention to the large copper die template test you will of course notice some very find results there. 24 degrees is relatively high, but it is sill a good performance indicator on this large heatspreader based processors - which don't really exist at this wattage anymore, but what the heck, the VIA C3 is available and would be applicable.
