dd gallery
Nuuk, and anyone else who has GC galleries, if you think this is worthy, feel free to post my pics in your gallery (full version and more pics are on my temporary web site linked in this thread and "www" below). Just send me an email so I know. My pics take time to load due to slow web server, just hit "refresh" to get them all.

Yes, I have used those heat sinks. I have actually been telling everyone here about the heat sinks and WBT RCA connectors (both of which you see on my GC) from Electronic Goldmine for a while, even back when they (the heat sinks) were not even discounted as much as they are now. I was so new to this forum I didn't even know if this was proper behavior. See:

I note that they do ring somewhat when dinged with your finger. So dampening is somthing you might want to conisder. I've tried felt pads underneath, but interwoven rubber bands seem to work the best. Whether or how it affects the sound I am not so sure of yet. I like a sharp HF response, so maybe it doesn't bug me.

An externally hosted image should be here but it was not working when we last tested it.
Full story
here.
One possible source for the bad LED publicity...Nuuk said:
I've a NAD CD-player and one thing I remember from reviews around the time is that NAD said they'd used an LCD for the info panel rather than the usual LED panel to reduce noise from the rapid multiplex switching of segments carrying several mA each.
However, an indicator led on steady current is a totally different kettle of fish.
Ventilation
OK, the heatsinks don't get very hot unless you really work the amp, but I do so I was concerned about this. I drilled some ventilation holes in the cover.
I don't know if I said this before, but I have a very very minimal set of tools.
So I created a hole pattern on the computer that would overlap the heat sinks, printed it out taped it to the cover and drilled away. Here are the results. You see that some of the powder coating on the chassis cover kind of stuck and didn't drill away. Anyway, the ventilation seems ok and I can make the holes bigger if necessary. Also, if you look at the web pages you will see that I planned for this in that one of the first things I did was to drill vent holes in the bottom of the chassis to allow for convection through the top holes when I got around to drilling those.
This ventilation is pretty good, but not great. When playing this very loudly, the sinks get hot enough to burn your hand, and the vents don't really evacuate air that quickly. I'm going to do a kind of thermal study to see what gives, but it certainly works just fine and I've had no problems with extended high volume runs.

well here are some fans i can suggest.
http://www.sidewindercomputers.com/vantec40x40.html
or
http://www.sidewindercomputers.com/sunon40x20mm.html
slightly bigger and quiter depending on how much airflow you want.
http://www.sidewindercomputers.com/sunon50mm.html
or
http://www.sidewindercomputers.com/sunon50mm1.html
last but least this 80mm one
http://www.sidewindercomputers.com/sandenpetace.html
Might be able to tie them into you led panel? All the fans list will run on as little as 6-7v DC.
Hope that gives ya some ideas on cooling. Not sure if it would affect SQ of the amp though.

I really like the Fans from Papst, really really quite with a good airflow and decent cost.
