If you're done rolling your eyes at the headline, let's get down to business. HP Spectre X360 15-ch000, about 3.5 years old, well-taken care of, but the fan(s) have been sounding... aged for at least the last year. The fan noise escalated quickly in the last week (think teeth on a chalkboard... you're welcome) to make this change necessary. Preliminary results: so far, so good.Instructions are a little lacking but if you're daring to perform this procedure, you probably already know what's up. YT has a very basic HP-produced clip for the assist (search: hp spectre x360 15 ch000 fan, first hit). Bottom of laptop underneath the grip strip closest to the screen hinge has 4 P1 screws, and 2 T4 torx at the front corners (be gentle with small heads). Use a plastic tool all around to pry up the corners and wollah.Disconnect battery. Lift the black tape at the ends covering the fans to access 2 more P1 screws per fan, with a couple wires running along the sides. Pretty self-explanatory: unguide/disconnect the appropriate fan connectors, maybe hit the board with some compressed air while you're at it, slide and maneuver the replacement fans in, and reverse everything to complete. Don't be like me and remember to reconnect the battery after you've buttoned up.Note 1: the product info includes thermal paste. Maybe I'll take some heat (see what I did there) but in my rig, I don't see where there may have been thermal paste to reapply. The fan slides between metal on metal. Not sure what to do with the paste.Note 2: I use 3M 1/4" double-sided tape to reapply the grip strip. I've done it several times because the older HP models run hot, gum up and loosen the adhesive, and the strips start to slide and fall off. HP either hates us (probable given their printer strategy) or use chromebooks and are oblivious to their own design flaws.First boot took me to the error virtual keyboard screen - probably didn't like the battery disconnect. Hit OK, boot normally, ran some stressful apps to get those fans churning, and sounds AMAZING. No more buzzing from fans.Note 3: For the real nerds out there, I did NOT do a before/after benchmark to see what the RPM/voltage difference is. The fans are exponentially quieter than the originals. I feel the airflow difference as I put more demand on the processor. It's working.Overall cheap, quick, simple r&r. If you've ever replaced any component in a PC/laptop before, this is a 15ish minute breeze. Add time if you clean and reapply the adhesive. 5/7 with rice.Rest assured I will update if these don't hold up.UPDATE: Downgrade from 5 to 3 stars. Fans have been installed for about 2.5 months now and unfortunately the right fan under the 10key has deteriorated. I don't know if it's an HP issue, fan mfg issue, design issue, or whatever, but the buzzing that has returned under low load (browsing) is agonizingly loud. Gonna have to find another alternative that'll prevent me from throwing the laptop off the balcony, especially since the new x360s ditched the 10key (seriously what was HP thinking).

Love that the fans were marked for were they needed to go.Connections are delicate but secure.

Working good, Thanks

So your fan is failing and you are annoyed by the noise it is making but you endure until it suddenly stops and doesn't do anything at all anymore. It is silent, what a bliss but now your computer starts to crash and you get a start up screen which says your fan is failing! It is barely workable as every 5 minutes it's freezing up and you need to do a hard reboot. So you call HP and they bluntly say "Sorry but we don't support laptops older then 5 years. Replacements ... nothing local it's either Ali express (China) or Amazon (US). I live in Belgium (Europe). Ali Express will take weeks and I can't work without my PC so I took the risk with Amazon. It's Friday and these fans are in Louisville KY and have to come to Ghent, Belgium. I looked it up, that's 6500 miles and an Atlantic Ocean in between. Promised to me by Tuesday. So I was like yeah sure, be real guys that only 4 days right before a weekend. So I must say I was a bit surprised when they dropped in the mailbox on Monday afternoon. The correct model, its already installed and I am up and running again. Pretty impressed I must admit!

These parts were perfect replacement and llowed me to add a few more years of service to my lptop.
