Fans Speed Issue after BIOS Driver update!

[DiscoingGD]

I've had this computer for 3 months with no modifications, except mounting an additional fan on the 120mm bracket up top, plugged into the LC PUMP on the motherboard.  It's been running fine, fan and all, except occaisionally it would give BIOS error beeps (3 long, 3 short). I read that a few people had this problem and that downloading the BIOS driver update would fix it, so that's what I tried to do. When I restarted, the fans now run at full speed, even at idle when temps are cool. They always ran quiet before, even while gaming it rarely got this loud. Now, a mistake on my part is that I downloaded an extra driver, as it was on the list of drivers for my product, but I didn't notice that it had a different motherboard ID.

I'm not sure if the wrong driver went through and messed this up or if the correct driver overrode that but still caused this issue. If it is the former,  I need to know how to revert back my BIOS so that update no longer affects me? If it is the latter, I need to know why it messed with my fan speed and how I can fix it? Any help is appreciated!

Greetings,

Welcome back to the forum.

I am not a HP employee.

A 3:3 BIOS error code is a graphics initialization timeout.

I don't recommend connecting a fan to a motherboard LC Pump header. I can't see this Pump header connection when reviewing your motherboard (MB) at this HP Support site (Link).

Disconnect the fan from this MB header if one exists to see if this helps.

Try resetting the BIOS to defaults.

It's hard to read because of the small print, but in your link where it says "System Fan Connector", there is an identical 4 pin port just to the right of it, though it is labeled LC_PUMP (Pic below). It has been working fine for a couple of months, though I believe you if you say a regualr fan shouldn't be plugged there. However, they give you a 120mm backet to mount a fan on top, but I don't see anywhere else to plug it in?

Anyway, how do I reset my BIOS to defualt and does it hurt the computer to do so? Also, if that does not help, how can I manually set my fans' speeds?

Hi DiscoingGD,

HP does not provide BIOS settings to modify individual fan curves.

You can reset the BIOS to defaults as follows:

Restart your PC

Tap "F10" to enter the BIOS

Select the "File Menu"

Select Apply Defaults and Exit

Resetting the BIOS to defaults will not cause problems unless you have modified any BIOS settings. You will then have to reapply any BIOS modifications you made to default BIOS settings after resetting BIOS defaults.

BIOS default settings will not harm your PC.

Login to Windows. Check to see if fans have calmed down.

Then I would disconnect the fan connected to the LC Pump.

Restart the PC and check fan speeds again.

I don't know what to tell you if fan speeds are still out of control.

HP BIOS updates are usually not reversible.

F10 got me into BIOS as instructed, but there was no File menu. There was an Exit tab and it had a load default on it, but trying that did not help. At idle, HP Omen Command Center shows the CPU and GPU at less than 40 degrees C. BIOS shows CPU fan and System fan at 1000 and 900 rpms, respectively. I don't know what the normal/max rpms are for them and thier is no reading for the LC_PUMP port, but it wan't even this loud when I was gaming before. 

I found instructions involving recovering from a catastrophic failure that involves pressing the windows and B keys while holding the power button for 3 seconds. Would this revert my BIOS to the out of the box state? If so, I'll try it. I'd rather deal with the occasional beep codes than the fans running noisy 24/7.

Also, where can I go to report this to HP's techs so they know there's a problem and can hopefully create a patch (Assuming others are having this problem)?

Hi,

BIOS settings and navigation tips can be reviewed at this site (Link).

A BIOS recovery may not help in your situation. This option is normally reserved for recovering a from a bad BIOS update or existing BIOS corruption.

Contact HP Support (Link) if you are in warranty. You should be in warranty.

I would not mention connecting a chassis fan to the motherboard pump header. 

HP can void your warranty when you do things like that.

A different forum member contacted HP Support with a problem that occured after adding a graphics card and updating Windows to the Pro version.

HP would not honor the warranty. HP Support warranties factory hardware, hardware drivers, and factory software only.

When you mess with the hardware configuration you mess with the warranty and can possibly damage the PC.
