Architectural LED Lighting 260mm Diameter Passive LED Heat Sinks - FrostyTech.com Architectural LED Lighting 260mm Diameter Passive LED Heat Sinks
Mon Dec 06, 2010 | 3:55P| PermaLink

Architectural LED lights require efficient heatsinks to keep the high power LED diodes at proper operating temperatures. Get it wrong and the diodes overheat and burn up. In recent years heatsinks have begun hitting the wall of decreasing CPU thermal design power, what used to be +150W TDP is now 125W or 95W.... yet the opposite paradigm holds true for LED lighting. The particular demands of lighting have thus spurred industry to come up with innovative 100% passive heatsinks, that means no noise and no fans in the face of heat loads that can approach 300W.

We're always interested in hearing about new heatsinks at FrostyTech, thanks to Gary Chang from nPowerTek out of Taipei, Taiwan, we have a few photos of a new industrial LED lighting heatsink that rolled off the factory floor three days ago to share with you. According to nPowertek, the typical application of these passive heatsinks is for industrial / plant factory /outdoor sport space LED lighting cooling.



( Test report for the 260mm diameter, 185 fin npowertek NPH L-260185-56S LED heatsink stressed with a 200W heat load.
The reported temperatures are 1) PCB front, 2) copper base, 3) heatsink center, and 4) ambient temperature. )

Interlock fin diameter 260mm H:95mm / Heat Column diameter 40mm/ copper base diameter 102mm/Fin num 79 fins/ Cooling watts: 100watts fanless 1.6Kg

Frostytech has tested nPowertek heatsinks in the past for AMD/Intel CPU platforms, but like many other thermal solutions nPowertek is working to meet the increasing demands of LED lighting heatsinks - these range from home lighting to architectural LED lighting on the sides of building and flood lighting in industrial situations. nPowertek builds its heatsinks around the companies proprietory heat column technology which range from 25.4mm to 56mm in diameter, and lengths of between 56mm to 400mm.

Thermaltake ISGC-300 CPU Cooler Review  - FrostyTech.com Thermaltake ISGC-300 CPU Cooler Review
Fri Mar 05, 2010 | 2:12P| PermaLink
"I had high hopes for Thermaltake's ISGC-300 cooler. I liked the design and it was very easy to install on the 775 platform, although the mobo may have to be removed for installation, even for AMD users."
