I've wanted to do a passive version of the Intel NUC module since I received it in the recent BitTech contest. the tiny fan that came stock was dead silent, but the heat blasting off of it told me an upgrade was needed. One healthy ball of dust could play hell with it. Let's face it; passive systems are NEAT. I have a set of monster server heatsinks that can be used here. First I needed to make make a plate to attach to one of those sinks... EDIT:Sinks came from a Dell Precision 620 with dual Pent3 Xeons. -The main reason this has taken a long time to get finished was that I burned up another motor controller. You can see all kinds of madness occurred while trying to cut the plate. That one path where the bit tried to go to California made it painfully obvious. This pic is after the cutting was completed properly, so some of the real horrors were deleted. That bottom edge still shows off some of the stupid, though. -So a big heat sink wasn't enough for the last motor controller? FINE! I watercooled this time. -I left a little too much of the heatsink mounting offsets. The mad motor controller lopped off a bit of the posts, but not enough for the chips to touch metal. -Here's an initial test fit. You can see that most of the cutting was to clear electronic bits on the board. -You have to mount the new plate to the NUC, then bolt the sink to the plate. -1st problem: I don't have a HDMI monitor, or a compatible connector. So I took it to a friend's to see if they had a cup of HDMI monitor I could borrow. -By some miracle, it booted and seemed to work even without TIM between the plates. I can start a log and build the enclosure part now. Here I'm cutting the edge of the plate even. You can see the countersunk holes for the NUC mount. I dug around in my jar of laptop evicera to find some tiny but long metric screws.
