5V 0.4A 4Pin CPU Fan, 5.5cm Connector, Server Blower, Compatible with Lenovo A4980, B300, B305, BSB05505HP

I have been running a NUC 5 nonstop for 6 years that is still going strong but decided I should replace the fan before the old one died. I knew Delta fans are noisy but they are very tough, and the one in my always-on 6-year-old NUC is still working fine, and even when it spins up, I never hear it. (Note: These little fans always run much faster than larger fans, and that's to be expected.) I replaced my 6-year-old fan with an identical model and nothing changed, which is what I expected, as I could occasionally blow compressed air through the air vents in the NUC to get rid of any dust that might have collected. Incidentally, you can find these Delta fans (this exact model) for a great deal more than $10 but don't fall for it. To the best of my ability to determine, this is identical to the fan I replaced. The main label (on the center of the unit) matches exactly. There is another sticker that differs but that is very probably a vendor tag.

My Intel NUC fan started to make a squealing noise and I knew the end was coming. I opened it up expecting to find a small box frame like any other PC, and was dismayed to find it was a low-profile impeller with some ducting because it looked custom and I didn't think it would be easy to find. As it turns out, this particular fan-with-duct is used in a lot of products, and was advertised here as fitting other Intel NUC models. So I tried one and found it was a perfect fit for my NUC5i5BNH. Since that wasn't already listed as a compatible model, I've written this review so that more people who might need this fan can find it. Getting to the fan isn't easy, there are a lot of tiny connectors to undo. The original fan held one of the mounting screws captive, but I used pliers to remove the washer so I could reuse that screw. This replacement has restored the near-silent operation of the NUC.

Installed in my intel Nuc with no issues.

I ordered four of these to replace the fans in my four aging Intel 7i7BNH NUCs, along with a good cleaning and thermal compound replacement. They installed easily, except one had a screw inserted backward, which was an easy fix. They blow a good stream of air, so I’m hopeful they last as long as I use the NUCs.

I replaced the fan in my NUC7i7BNH. Works like a champ!

I gave it three stars because the fan arrived damaged - the metal shield covering the fan was slightly warped inwards and was rubbing the fan and preventing it from spinning. I fault the packaging which is the usual lightweight yellow envelope internally coated with bubble wrap. Any pressure on the packaging could have warped the thin metal shielding. It was a fairly simple repair - carefully removed the shielding and gently arced the center upwards and away from the fan. The fan is a perfect physical fit for the Intel NUC model #11-1135. However, this fan has a four-pin connector while the stock fan has a three-pin. The conversion involved removing the three pin connector from the original fan, removing the four pin connector from the new fan, and placing the original connector on the same color wires (black, yellow, red) onto the new fan. The fourth blue cable is a speed control, and isn't supported by the NUC and so it's not necessary - without the blue wire the fan runs at full speed just as it did on the original fan. This fan is draws .4A whereas the stock fan drew .25A. Those older stock fans don't appear to be as available, and so a side benefit with the new fan is that it runs faster than the older one and keeps the system cooler overall. No issues seen with power draw. I gave the fan 3 stars because it arrived damaged. I would have given it a 5 otherwise.

Perfect fit for my 4 yo NUC and works fine. Sadly didn’t prevent my old box from overheating and shutting down, but that’s probably bc it’s just super old now (and has been worked hard as my plex HTPC).

Fans make scraping noise. Made adjustments to the fan shield which helps but the scraping noise eventually returns. The noise is most noticeable on start up but eventually due to harmonic imbalance can be present at idle speeds.

Was skeptical of how the product would fit but, was pleasantly surprised to find it was and exact fit for my failed fan. Super easy to replace.

Excelente. Llego antes de lo esperado y funciona muy bien con mi computadora

Works well and fit inside my Intel NUC7i5BNH.
