Where did u see them?I was just having a look at the arctic alpine 11 & 12 passive heatsinks. Can be bought for roughly £10 a piece & good for around 50w. Strap a cheap fan on one of those & it would probably handle quite lot.
I saw them mentioned on another thread. They are available on amazon & multiple computer parts shops online. Google them, you should get plenty of hitsWhere did u see them?
Last time I checked (while ago) kingbrite was the cheapest. I'm going to be adding a few cobs to my existing Cob set up. Not keen on adding strips. I'm pretty sure I looked at prime light a while ago.Try asking primelight for prices on their mechatronic (or whatever its called) heat sinks, they are a citizen supplierin uk.
I got mine from china, it worked out much cheaper even after tax and shipping. Kingbrite..
Shame we don't have any pin heat sink distro here or a heatsinkUSA..
Could always go with strips and do away with the need for big heatsinks .
Its alibaba. Renxin is the Company though.I'll have a look at their website. Cheers Airwalker16
Very smart move to use a sink built for passive and throw a fan on it.I saw them mentioned on another thread. They are available on amazon & multiple computer parts shops online. Google them, you should get plenty of hits
Renxin did mine all the way I wanted. You just gotta tell em what but they usually want a blueprint of the holder/COB you're using.I’m pretty sure from memory that someone posted on a thread that they had drilled & tapped either a cxb or luminous to an alpine 11 including cob holder. I know they have a little raised chunk in the centre of the sink so that is the concern. If I go that route, I will probably just buy 1 to check the dimensions work. They are only £10 roughly so its not a great loss if it doesn’t work.
That said, it would be a lot of drilling & tapping which I really hate. The last time I did that, I did have a tap break off half way through which is a pain in the ass to deal with. Heatsinks from Kingbrite come pre-drilled & tapped which is a huge time & effort saver.
