Heatsink for High Power LED

[Terryz_]

Hi, anyone can shed some light on the size of heatsink to get for high power led, Like 40w-100w LED...

Would having a fan increase the dissipation of heat thus a smaller heatsink can be used... Correct me if I am wrong...

And possible anywhere to get the heatsink with fins in Singapore, I know where to get alumminium panel...

Bro if u want just finned heatsinks, try sim lim tower 2nd or 3rd floor, saw some there before but mainly small blocks up to 6in.

How high power is the led u planning to use? I'm currently planning for heatsinks for my 10w leds and may go for low profile cpu heatsinks if the price is right

Any idea on the price?

I am thinking of minimun 40w... But I am not sure if the cpu fins heatsink can handle the heat anot...Not getting my hopes high becos a fellow reefer said that it is not enough to dissipate the heat and might overheat the LED...

Wow bro new project coming ? Maybe you can try taking a walk to Sim lim tower and you might be able to find what you are looking for ..

Actually the thing I wanna to findout if the calculation for Deg/Watt is really that crucial...

A heat sink can only do so much on it's own. You'll need additional cooling feature such as a fan to assist in dissipating additional heat. If you're worried about practicality of adding heat sink, I believe a multi rpm fan is a better choice. Heat sink might add additional weight to your lightset and also in time, it will be a dust collector and cleaning heat sink is not an easy job.

Think a combi of heatsink and Fan will do nicely... my current set is using multiple 10 w x18 without any heatskink... Just old aluminium plate and 2 fan.....

The heat sink that I posted have a fan attached to it.. I din post the photo up... LOL...

So this should work fine right... Becos from the specs, the operation temp for 50w is 60C so that is the same as processor temp mah...

Most CPU heatsink with fan can support up to 20 watt led only.

If you looking for more heat dissipation due to higher wattage led

then you have to look for fluid cool heatsink use by most gamer

Locally I am not able to find any.You have to go ebay or US web to

source for them.
