I know this thread is kind of old, but I'm just putting this here for anyone who has a 7th gen NUC like mine, which is model 7i5BNH.
If you're sensitive to noise, the stock cooling fan that comes in these machines is really annoying. Like a lot of small fans, it produces a high-pitched whine, even at lower speeds - I'm not sure what kind of bearing is in the stock fan but it isn't a good one, that's for sure. The good news is there is a replacement from a company called Sunon that uses MagLev (magnetic levitation) technology which means it basically floats frictionlessly when it's spinning, and the reduction in noise is such that you can't hear it at all, except when it's running at top speed.
I was reminded of this because the one I installed in 2018 finally gave up the ghost last month (after 7 years of 24/7 use) so I had to replace it.
If you want to get one of these, the model number you're looking for is GB0555PDV1-A - I got mine off AliExpress for about 5 bucks, but you can find them on eBay as well for $10 or so.
There's a YouTube video here that walks you through removing the old fan and installing the new one - fair warning that you do have to disconnect/reconnect a few small connectors to get the circuit board out of the chassis, but if you're computer repair-savvy at all, it's very straightforward.
