How are people justifying the expense in this? It sounds like we're back to being GPU hobbyists again, except this time with an even greater lack of understanding of what we're working with. Not that there's anything wrong with that.
But just for reference; Spending $100 USD on aftermarket fans will set your ROI back about 30 days. Are people really considering water cooling?
It's fun?
I water cooled a Neptune on a lark, it actually works very well. I have thought about pulling a bunch of little heat sinks off some other things and making a mongo cooler, maybe I'll do that over the weekend. But water cooling a bank of Titans should work.
However to be honest that tower heat sink is not bad...
And now I'm really confused. Is the bridgeboard a completely passive device? You mean we could just build a cable to replace it entirely?
Amazing! One just showed up in the repair queue and I can look at it.
It's pretty much passive. Some LEDs tied most likely to GPIO ports, that's nice but not necessary and one shiny capacitor on there, probably for the 5 volt supply. Yeah you could probably rig something together but those bridge boards are a much more elegant way to go.
The real rock and roll solution is to port the code to the beaglebone. So far I have the FPGA loading the titan firmware, powering up, and I think the stuff for the web site just needs a quick java fix. Annoying that the stock BB freaks out on reboot and overwrites all my hacks, I'll have to disable that.
