Computer Heatsink idea?

I just went through a ~8 year old PC in my basement and managed to extract a couple heatsinks, fans, a 300w power supply, and a 4x burner...

I'm interested in using this heatsink...

And sending it off to someone on the forums with a lathe or drill press to drill 2 ~12mm holes to fit 2 Aixiz housings.

What do you guys think about this? Will it work well with a PHR and LPC continuously on? Or is it better to fork out $30 for 2 pre-made heatsinks.

Thanks in advance!
 





That would probably be ok for a relatively low power diodes like the PHR etc, but for higher power, you'd probably be better off finding radial heatsinks like this.

My cost on these are $3.18 each in quantity, but it's not hard to find them with copper cores as well but those cost more.

On these particular ones, the core is 20mm in diameter, and the heatsinks are 31mm deep.

Also, being an 8 year old pc. Was that a 4x DVD burner or a 4x CD burner? It matters. CD's use IR diodes. DVD burners are the ones that use the visible 650nm red.

Do you have a drill press or lathe with a 12mm bit? If you can drill it out for an Aixiz I'd buy a couple! Otherwise the cost of shipping it to a driller, the cost of the heatsink, and the cost of shipping to me would be more than a premade heatsink.

Edit: The burner was DVD, but 4x isn't going to do much so I didn't bother to try using it.
 
I've considered selling them. Which is kinda why I ordered 20 of the things heh.

I'd probably sell them for $10/ea plus shipping for just the heatsink/fan etc hardware that they come with, after the trouble of machining a 12mm hole, and drilling and tapping another hole and adding a setscrew.

You'll have to wait for me to get a few done first though. I'm still waiting on my order of aixiz modules to get here.

Plus I haven't quite figured out where the setscrew will be best located, so i'll have to ponder that a bit once my modules show up.

Ok, no problem. When you have them done, shoot me a message.

Anyone else have opionions on my idea? Would it even be possible to machine an even hole on my heatsink with all the fins in the way?

Also, on a side note, if anyone wants the gfx card, cpu, ram, or other smaller parts, you can have it, just pay shipping.
 
It's certainly possible, however due to the small contact area each fin will present the aixiz module, it'd almost have to be a press fit for it to work reasonably well. The fins on that one look thick enough to stand up to drilling so long as you didn't get in a hurry.
 
You might try instead to drill the bottom of the heatsink, the part that contacts the processor.
 
Using a computer heatsink, try to set the module into the thickest part of the Al block.
Thermal conductivity is like electrical in that the bigger the conductor, the more heat transfer.
Here's a computer heatsink, with copper spreader, fat-side forward. It can run at >1A
indefinitely with no appreciable heat rise. It had a fan, but it won't need it unless Nichia comes out with a 10W diode :-)
