OMEN 17 ck1000/ck2000/cm2000 intermittent fan dysfunction

Another update: I am now on my Tuxedo Laptop as of writing this. Again, I'm kind of sad that HP didn't take action regarding all of this. I honestly hope that people that are affected get their money back because this is unacceptable in my opinion.

I reiterate that I will probably update this forum post with another follow-up reply if I happen to fix the fan control issue when I go back to France.

I’m going to try to contact directly HP in Argentina to see if I get a solution or at least a response (I'm waiting for them to reply an email to see if they'll receive me at their offices) … but from this experience I’ve learned that HP’s entire structure is set up to avoid dealing directly with customers or taking responsibility for this kind of problems. They know perfectly well which devices have failed, they know who the owners are, and even so they still don’t give us an answer.

I can tell you the BIOS Version did not change a thing, I got an old one from 2023 and have the issue too. I have a AMI F.08 10.08.2023. I will update to newest now (F.13.) but expect nothing to change.

I have the: OMEN 17.3 inch Gaming Laptop PC 17-ck2000 (70W99AV) and this problem came after 2 years out of nowhere and all the normal steps didnt solve the problem.

Just started today, almost **bleep** myself. Decided to clean out the dust, thinking "that's a normal thing to do".

Didn't do a **bleep** thing. Found this forum thread via reddit and glad I did.

Posting from Australia.

I had the exact same issue begin in December and it’s still on going on my HP Omen 17 in australia, has there been any news from HP in the new year yet?

I'm getting it looked at under warranty.

It seems to be a widespread problem with all Omen laptops. Why they don't send out a PSA is a bit beyond me, especially for such an expensive laptop.

@NegativeNelly, I'm not too surprised because HP decided that it is more cost-effective to handle per-user cases than making it a global PSA. Not saying that this is a good way of managing this at all, but they seem to prefer taking that route unfortunately. Don't hesitate to give us an update on the matter!

This is not a EC or Software Issue. I spent many days on this matter and finaly came to a conclusion.
Here is the things i have tried:
- Replacing fans with brand new units.
- Reverting to old BIOS versions with a external chip programmer.

- Testing with Linux and Windows (with & without omen gaming hub and with open source omen specific bios / ec fan controller softwares)

My final observation is:
This is a mosfet solder cracking issue. Which explains why problems increased over time.
Here is what my laptop has been gone through:
"- Firstly, while gaming i experienced the fans rattling (i suspected bearing is gone bad and replaced the fans at this time) and cant change speed as normaly or stuck at same RPM. 
-- Which indicates the solder was starting to crack. Thus making the voltage non-stable. 

- Secondly, fans started to on and off. In this time period i tried Ubuntu, which i could control the fans and it worked. I could easily get stable RPM for hours.
-- Solder is getting worse.

- Thirdly, i was getting 90B error in the startup and the fans were not booting up. But if started working for once, they kept going strong for a long time. Ubuntu method doesnt work anymore.
-- Solder is gone too bad that it is not stable even if the laptop is cold.

- Lastly and currently, the fans are dead. Almost no booting up. No software can control it."

We believed that is a EC problem because resetting bios worked for a short time. But i can confirm as the solder crack increased this method doesnt work anymore.
I have a Omen 16 2022. Which has the same motherboard type as Omen 17 models. The mosfet is probably a cheap unit with a poorly placed position and with weak solder. Very close to the source of heat. And it is exactly positioned in the WASD keys, the palm area. Which can increase the pressure on that area of the motherboard.

Please try to press the area above the F3 key. This will bend the motherboard (The area is a empty spot where the fan pipes are in there, no motherboard. Which is a very thin place that can disturbute the pressure to the PCB). 
The fans will work for a short period of time because it is rejoining the solder cracks. I can confirm this. But if the laptop is hot this is not working (For me). This also explains why the motherboard replacement works but 
the issue still arrives after a period of time. 

Please spread the word. This is not a software error or a user fault. Just a poorly designed product that is doomed to be broken.  Please file a report to authorities and share the results  publicly so we can do the same thing with stronger evidences.

I have the same problem and i noticed that i can restart the fans by hitting the keyboard, i thought they were "kickstarting".

I also replaced the fans hoping it was a bearing issue but it fixed temporarly.

So, a somewhat permanent solution might be trying to resolder the mosfet maybe with a heatgun?

Yes and we need someone to try it first. We need to locate the faulty part and might need a microscope.
Here is the faulty area of Omen 16 2022, almost the same motherboard with Omen 17.  (I am sure because i can hear crazy voltage sounds)
Please send photo of the same area for the omen 17 ck2000 series.
