BSB05505HP BASA5508R5H 5 V 0.40A 5.5 CM PWM Cooling fan

I have immediately bought a spare, and am so glad my CPU did not fry. This seemingly is a very common replacement fan for laptops and NUCs. Inside a NUC, except for RAM and a SSD, you need fine motor skills! I had castrated drosophila melanogaster (tiny fruit flies) under a stereoscopic dissecting microscope, and I actually have fine motor skills. One needs very fine screwdrivers and tweezers. There was a lovely YouTube of my exact slim Intel NUC7i5BNK. Reattaching the Wi-Fi antenna was the most worstest, but now I can do it very quickly.If you keep notes as to the wire harnesses and their orientations, and have the tools, and have actual FINE MOTOR SKILLS, and if you haven't fried your CPU, you can replace the only moving part, the cooling fan. I cleaned my original fan and that worked for about two hours.This worked, for me, so well I have immediately bought another spare fan. I know some Lenovo laptops, HPs, and other laptops use this fan, too.If your NUC gets hotter to the touch, or has that polyurethane burning smell, pull the plug and think, "Cooling fan." Regardless, run Psensor in Ubuntu or CoreTemp in Windows.

I returned this item because it had a broken wire and couldn't get power to it.I don't know how well it would have worked if the wire wasn't broken, it felt of poor quality though.

This was a perfect fit and worked well. It made a little bit of bearing noise for the first few hours of operation and then settled down to just the minor wind sound that it makes.

Clean and easy replacement fan for my HTPC. The original fan went out and the CPU kept over heating and shutting down. This was as easy as plug/play. Now my HTPC is happy again. Fan is keeping the unit cool.

New life into my old intel nuc, not an easy install. Perfect fit.

I purchased this fan to replace the one in a gen 2 Intel NUC. Installs easily and works great. It's also very quiet and unnoticeable during operation.

Intel wanted me to ship the entire nuc back for repairs. Shipping alone was $20! It was also an estimated 4 weeks for repairs. Bought one of these, installed in a few minutes and it's been working great. I bought 2 more as spares.

It worked.
