Aavid Thermalloy
I found this heatsink to be reasonably priced and good performance specs. It comes out to $80 per foot Canadian and can be cut to any length. Unfortunately Aavid will only ship 2 Bars minimum (16 FT). Check it out, maybe a group buy or something?

I would be very interested in a group buy! I hope we get enough people and pull this off 🙂
That, or I'll have to do something crazy about heatsinks .

What about R-Theta heat sinks. In my eyes they look nicer, about the same price and you could probably pick them up yourself.😉
coulomb,
I have no preference for brands, however in this particular thermalloy model I found the the 1/4 in base plate to be kind of flimsy. I like that to be at least .5 inch, 3/4 even better.
If you can find something a little better I would be in. Maybe we can have the bars shipped to Peter that can in turn cut them down, repackage and ship to destinations worldwide! You are on vacation Peter, aren't you? 🙂

Both me and Coulomb are located in Toronto, so is R-Theta. I could cut them on my mitre saw, but the finish would not be acceptable for external use of the sinks. The best way is to order them precut and anodized. It cost more but if you want to use them as a part of amps chassis it the least complicated way.
The sinks from R-Theta have the base slightly thicker (7mm) but the fins look better because have different thikness at the base and on the ends (2 to 1).

id like to get some of that heat sink and go in on that batch he wants to buy.. is any one else going to..
Peter please email me with your terms ok ? 🙂 I need atleast 2 matching heatsinks, and maybe even more depending on the pricing.

Trigon, which is one of the members here, bught recently 4 sinks in 11" lengths and paid CAD$360 if I remember correctly. I'd rather prefer to deal with a group of people because then my time would be spend more efficiently. If it's one person what's a difference between ordering them directly from R-Theta or me doing that and sending them to you? As I said before, I cannot cut them nicely and anodize after.😉
Now, there is one more thing you have to consider. If I buy them locally I will have to pay both Ontario taxes, PST and GST which is 15% on top of the order. If you are ordering from outside the province you don't pay it. Here goes my commission.😉
Hello Peter, I did ask for a quote from R-theta, but as of yet have received no response.
As for Aavid Thermalloy, they do have different Heatsinks with different base thickness, but I was looking for a value trade off. A .25" base is usually very stiff, as I build my chassis from 3/32 Aluminum I assumed .25" would be sufficient.

i need heat sinks.. for my aleph 2 soon
i have my set up for my aleph 5's already
here is a cheesy way for me to build my chassis and waste no money it is done with card board but youll get the idea
1st the air comes in from teh bottem and travels towards the back and then straight up over the fins.
2nd the amp is inside over top of the wind tunnel i think my desin will be perfect.. i was up till 2 amp builing this cardboard beast and well it payed off.. here it is ..

Don't get me wrong Dude, but when I saw your cardboard beast I couldn't stop laughing.🙂 That's a quite original approach I must admit. You didn't use hot glue to put it together, or otherwise it might melt when power starts to be generated.😉

yeah i was laughin when i was building it but that is just a case idea not the actual box im building it out of aluminum like most people to i have yet met some one to build one out of card board..

Jason,
I guess it just a prototype and not final enclosure. Looking at your output board I can't figure out how you mount output mosfets. You screw them through PCB or what?

So before soldering you have to screw them to board itself. Another interesting idea, I guess it helps to distribute the force more evenly when the devices are mounted to the sink and removes the tension from the legs. Never seen it before though.
