||Thrmaltake copper sinks, up to 40 watts, pulsed .
|I have used this sink/fan combo on several LED combinations, so far;...
single 10 watt,as brake light replacements....
single 20 watt, with an additional fan, as
Four x 10 watt, pulsed @ 50% duty cycle, with an additional fan
... Very tightly mounted inside the brass kerosene taillight of a 1904 Pierce as a safety flasher unit.
The additional fans are because I had to mount inside classic car enclosures with poor natural convection.
The Thermaltake fans are super quiet.
No LED failures at all, on any of these power dissipation levels, which surprises me for such a small, thin heat sink !|

||Nice small HS for lasers!
|Good heat sink but because the copper is soft, minor lapping of the contact surface might be needed.|
