Guy:

Keeping them separated doesn't really matter, for all intents and purposes. If it did, I guess we would be saying that there is some significant difference in the heat transfer at the edges of the sink (where it is adjacent to its neighbor) than in the middle. In fact, the fins must be spaced within a heatsink such that adequate heat transfer to the air occurs and is not compromised by the next fin doing the same. So they are not particularlly more efficient at the edges such that placing the next sink nearby will compromise their operation. Hope that makes sense .

Can't comment about R-Theta's willingness to ship internationally.

Peter,

Could you tell me if two of the 65340 heatsink would be enough for each Aleph 2 monoblock?

FWIW-
I have obtained a quote on MMMetals extrusion 11645 (see above posting) for 15-25 pieces (for Aleph 2 ala Wayne Sankey).

Any interest in driving the price/piece down?

Steve A,

This thread is only for R-Theta heat sinks. I personally prefer those sinks and won't decide on anything else.

You can start another thread on Wayne Sankey heat sinks.
What was your quote anyway?

They should be fine.

I am with Peter 150% on this one. This thread is for R-theta only.
One thing is to get some bargaining power another is to want to switch the source. First of all, do AAVID an MM anodize their heatsinks? If yes then AVID profile that Brian pointed to may be kept on the payroll. The MM baseplate is WAY TOO FLIMSY. The point here is to get the best price/functionality+ best looks and feel.
Even the extrusion profile looks great, material and manifacture can vary to an incredible extent.
I know what R-theta profile looks like and I know how nicely it is cut and anodized, I am not so sure about the others.

Peter-
Sorry. It wasn't my intention to change the direction of the thread. Being a relative newcomer it's not always clear when to start a new thread.

My quote on the extrusion from MMMetals was in the 25$/piece range.
