This is more of a mechanical question rather than electronics.
I have a nuc6i7kyk that is ridiculously noisy, so I thought I exchange the fan for a better one, but I didn't find a good quality fan that is compatible. So my next "bright" idea was to remove it from it's original case, and build a custom case, with an off-the-self heatsink and fan combo.
But it seems the holes for mounting the heatsink are not standard. They have 3 holes according to their STEP file arranged in what it looks like a equilateral triangle.
The BGA socket (named BGA_1440P_1102x1654_N in the step file) has dimensions 28mm x 42mm.
I searched around and couldn't find a heatsink that would fit the dimension of the holes or the BGA or the mounting holes.
I got a couple of quotes from online CNC's and a custom made heatsink seems a bit expensive (100's of $$).
I was wondering if anyone has any alternative ideas/suggestions.

Its a damn laptop fan :( I noticed some people had or have problems with the fan ... i dont know for the noise, my guess would be clean the fan ( you surely did it? ) and sometimes theses fan can be dismantled, maybe add teflon oil drop on the sleeve ?
Unless you go the hard route and hack it to be a fully passive cooling ? you have thermal pads going from 0.5 mm to 2 mm thick, and maybe use some old xeon server / full copper heat sink ...
something like this

With some drilling, tapping and add 3 adjusted in height sleeves / spacers you could have a totally silent pc ? not as compact ?
The originals fan are sold pretty high priced up to 65$ usd ?
