Mini-Aleph Heatsink size ???
 
Hi,

What is the minimum size for each mini-aleph xtor passif heatsink for 15V rail PSU?

Standard Socket 370 CPU Heatsinks without Cooling Fans, is it good?

Thanks

P.s.: Sorry for my engish, I'm a French-speaking

That's probably too small. My mini-a's heat sinks are approx 150mm x 430mm x 50mm per channel at 1 amp per channel. It runs very warm.

A way to test if it is too hot- if you can hold your hand on the heat sink for a few seconds without discomfort it is ok. If you can't hold your hand on the heat sink at all, even for 2 seconds, it's too small a heat sink.

Hope this helps,

Vince

Not very scientific, but for ideas have a look at the gallery on the pass diy website:
