Is it ok if only the yellow part of the cob be on contact with the Alpine 11?Arctic Alpine 64Plus and a few others are ththe only ones that'll work.
In this case it'll fit.

If you can fully mount it so the entire COB is touching the heatsinks it's fine. Holder isn't as important.Is it ok if only the yellow part of the cob be on contact with the Alpine 11?

Should work! Below is the Vero29 datasheet. Don't know if its the latest revision but dimensions for Vero29 are always the same. But its not fail safe! Always check the fans when you visit your grow area because if a fan or fan driver gets defective the COB would get really hot and could burn out over time. The alpine64 can handle only 40-50w without fan (<85°C).I would like to know the size of the Vero29 heatsink(the one in the back of the chip), Anyone?
The only Active heatsinks that i found on my country that may fit is the Alpine 64 GT (cant find plus size), it ill fit the heatsink area of a vero 29?
They will run a vero 29 at 100w
Pic didn't work.
Should this 300 MM x 41 MM x 8 MM heatsink work for 3 x CXA2540 in parralel or serie on an total of 50 watts ?
Offcourse active cooled with 3 ventilatorcoolers on top.
Edit: I am stoned and just realize the fans are 100 MM themselves.
So it is 300 MM x 100 MM x 8 MM .
Sorry for the late response , i also changed some plans.Pic didn't work.
But 4X12" is decent, 8mm height total? Any idea the base thickness??
Regardless, if there's 3 fans as wide as the heatsink, it will cool 50watts no problem.
In my country alpine 64plus stop selling. Last time i use this. Work perfect. Can you please recomend some other which one fit for vero29 with 70w? Can i use alpine 64pro? But It is not flat. ThxArctic Alpine 64Plus and a few others are ththe only ones that'll work.
As long as you can find out the dimensions of the raised are and determine whether a Vero can fit or not, it will work.In my country alpine 64plus stop selling. Last time i use this. Work perfect.

Not flat isn't important. What's important is that the cob can lay on the raised part and make contact to the whole cob.I can not find Cpu cooler which fully fit for vero 29. Alpine 64 GT and 64pro is not flat. Have you some experience wit somethil else like 64plus?
But the entire Light Emitting Surface (LES) which is what's generating heat, is fully contacted, therefore will be fine.Thx for answer. i found only this picture with alpine11. (no in stock in our country) And looks that COB not fully fit.
Consider MechaTronix IceLED coolers. They have holes and screw sites that will likely fit, though they're not tapped.In my country alpine 64plus stop selling. Last time i use this. Work perfect.

Just mount a PC fan on top of the fins pushing air INTO THEM. You can power it with something as simple as a 12v wall wart. You probably got a few lying around the house from old phone chargers and what not. That's your cheapest option other than dimming your driver.Hey all you cool cats and kittens,
First post in several years.
I was under a different name long ago but I forgot the name I used.
Anyway, I have a question about heat sink size if anyone has the time to help me double check this. I would greatly appreciate it.
I did the math to passively cool 150 watts of heat from my LEDs, and then I had a heat sink made.
Specs are 198mm x 200mm x 66mm ::
- 9mm thick base
- 27 fins @ 2mm thick
- 6063 Aluminum
I have attached the image of the specs.
I have become uncomfortable with how hot the heat sink is getting.
So I redid the math, and now I'm finding that I need 200mm x 220mm x 66mm dimension to passively cool the LEDs.
It's not much of a difference but I don't like that I've gotten different numbers. So now I'm completely doubting my ability to do math. Maybe my math has been wrong all along and is still wrong....
I don't typically ask for help, but if anyone would be kind enough to help me with this, I would really appreciate the help.
I have a lot of free time right now and I really need to figure this out. I can't not finish something I have started.
Thanks again for any help!
Hope you all are staying safe out there!
I do have some 200mm fans which will fit perfectly over this.Just mount a PC fan on top of the fins pushing air INTO THEM. You can power it with something as simple as a 12v wall wart.

A lot cheaper than having a whole new sink fabricated... Plus when you had it made, you always in all aspects of builds, wanna go bigger than needed. Whether it's a driver, heatsinks, extra strips/cobs, or what have you. Never a bad thing to have more when you need it then to not have it at all!
You don't need to have it be 200ma. Any 12v power supply should work fine. But 1/4amp 12v supplies aren't hard to come by.I do have some 200mm fans which will fit perfectly over this.
Fan Specs:
90cfm
.2A
12v
Rifled bearing (40,000+ hour lifespan)
If I can find some 200ma drivers at a constant 12v, I think that would work just fine.
I was simply trying to avoid using moving parts (fans). However if I want to make use of these LEDs with this panel comfortably, then a fan I must use.
