My HP GGJRCRF7 laptop needs a new battery. I have the battery and am
about to strip the beast down to replace it. However, the fan is noisy.
I assume there are multiple fans in the thing. Can anyone direct me to
either genuine fans or replacement ones for the HP I have? I really
don't want to pull it apart twice.

TIA

HP do sell spares like that. You might not like the price tho.

> or replacement ones for the HP I have?

Laptops are a classic where plenty get dropped etc
and the remains are available on ebay.

I havent checked aliexpress to see if that fan is readily
available there because HP used it quite a bit.

You should be able to find the maintenance manual for
the laptop online which has a full exploded diagram of
the parts and detailled instructions on how to disassemble
it and maybe even a youtube about the fan itself.

**Maybe. I purchased an OEM HP battery and the price was not too bad. I
can't imagine that the fans are anything special.

**Good thought. Still, it was and still is a nice lappy. Worth repairing.

is my daily PC.

**Yeah, I'll see what I can find. Once I have the HP part number or
specs on the fan, I'll be good to go.

Is that the best model number you've got? HP are one of the crowds
that put various model numbers on things, only some ever seem to be
easily findable on the web. "GGJRCRF7" might mean something inside
one of HP's offices, but try to find another model name/number on
it (even if that was the one labelled as a model number) which is
better known to the internet. Then you should be able to look it up
on HP's website too.

No idea for the GGJRCRF7, that's not a form of model number that HP
normally reference in public docs.

There usually is only one (if any) fan in a laptop though, for the
CPU and maybe other chips. Usually the CPU heatsink is part of the
same (often inseparable) assembly so you need to remove that and
clean then re-apply the thermal paste to the CPU when you install
the new one. Make sure to screw it down evenly too.

Another option is to try and get some light (eg. 3-in-1) oil into
the fan bearings. In old fans the sticker in the middle could be
pealed back and you could put a drop of oil (not too much) in
through the hole there. Modern laptop fans usually don't have a
hole, so I never worked out how to do that with them. If the
bearings are already too worn then it will only fix it for a short
time anyway, a replacement is ideal if you don't want to risk it.

AliExpress usually have reproduction parts if it's a popular model
internationally. Ebay will likely have people selling new and used
parts. HP might sell direct, but I'm not sure whether they do that
for their low end consumer models (if that's what you've got). It
should have a searchable model number on a sticker on the part
inside (often alongside some unsearchable model numbers, like the
one you've given for the laptop itself).

I downloaded the service manual and it's clear enough to show the
correct sequence to R&R the fan.

Fan P# is: L24935-001

I found one online for 60 Bucks. Way too expensive, but if I can't find
a suitable alternative, it will have to do.

**Yeah, that was what Windows ID'd it as. See above for the real number.

**Of course and thanks. The manual seems pretty clear on how to do the
job. I just hate pulling stuff to bits twice.

**Yeah, I've done that before in a pinch, but since this is my workhorse
and sees a lot of action, I'd prefer to replace it. Those sleeved
bearing fans only last so long before they cark it.

**Even for 60 Bucks, plus freight, it's worth it to me to replace.

**I guess it's a mid-end model. It cost me $1,500.00 in 2018. 4k video,
decent sound, 16GB RAM, 2TB rotary drive and 256GB SSD, i7-8550U CPU @
1.8GHz. So, not too shabby. The screen is lovely and the video output to
my two 32" 4k screens is likewise very nice.

A HP service manual should make the job pretty easy, at least so
long as the case isn't one of those clip-together designs that
don't like to unclip.

Sounds well worth a new fan.

They aren't but some of the lower demand items like
fans have some pretty silly prices from HP anyway.

You don't need the specs, some of the
better sellers list the models it fits.

Sure, but you don't need to if the seller lists the laptops it fits and
some do.

My Toshiba laptop display started going pyschedelic. It seems the
heatsink paste breaking down on CPU or GPU was a common issue with them.
Prick of a job, took 25 minutes to get it out and reassemble.

Did that work?

IIRC if the GPU give out rubbish, either the GPU or the VRAM is broken.

Yes it worked. I assume the GPU was overheating. Sometimes the screen
also went blank, but it hadn't apparently crashed - still responded to
num lock or caps lock keys.
