computer is a
HP Pavilion 764N

Hello, I am trying to fix a computer for a friend of mine,
he told me that one of the fans on his machine has been running a little noisey, and that also a little while back he received of fan failed to initialize
error, but what i had noticed when i turned it on
was that it did not seem like the fans were really spinning that
\fast and by that I mean the the one located in the
back that has the L shaped plastic piece that sits over the
cpu and the fan on the psu,
so at this point i am just looking for some of your ideas
should I just swap out both fans?
and is there a way to swap out a fan on a psu?
or should I find out what wattage the psu is running (where would I find this?)

and swap out the other fan and the psu?

thanks for any help guys (Your Awesome!)

I would first check the temps when the computer is on rest and under stress ( download,install and run speed fan ( link below ) ). CPU fan may spin faster and naturally noisy when the temps go over a certain degree. If you suspect that the cpu fan is failing swap it asap. For the Psu fan : It is possible to change it but indeed i would change the psu. How is the system fan doing ?

you can use either everest, or speedfan, or even motherboard monitor to check your speeds, temps and voltages.

get all the speeds, voltages, and temp values from your machine, and let us know.

fans do get old and die sometimes, and they do also clog from dust.

well, the temps aren't extremely high.

fan 2 is in pain and suffering, no fan should run as slow as 1,000 unless you have some sort of a speed controller on it.

as far as fan 1 and 3, i have no clue.

it's more likely that they aren't connected to the correct fan headers to be read by the temp. sometimes people do this to run them on the hard disk power leads, and then the fan speed isn't monitored, unless you buy a rarely used adapter.

fan 2 is spinning so slow, i suspect it's part of your noise problem, if not all of it.

bad thing is, fan2 should be the little chipset cooler, and that one is a little more of a pain to change.you'll have to carefully touch the center of that fan while it's running, and stop it for about 2 seconds, and see if the noise goes away.

also, alot of machines run perfectly fine without that fan anyhow. your temps are within fair range, even with that one fan suffering.

Shutdown, unplug the AC power cord, then remove the power cables from all the drives except the boot drive, and disconnect any external devices.

Restart the pc and check if the fans are spinning faster and voltages are different.

stu is on to something here, and it's a good catch.

i hadn't even noticed your 12v+ is down so low.


your power supply might be inadequate for your machine.

what i'am doing is I am going to let the machine run for
a while and then I'll post back temps,
the post prior was made within 15 min of the machine being on
and if i remember correctly the
hd0 stat showed the fire icon
after letting it run a while
I will also follow the directions mentioned above
and as far as a noisy fan
i have yet to hear it
it is one of the quietest machines i have ever run so far lol
which might be a bad thing

thanks guys

sorry i am using my buddys computer apparently it auto logged me into his account( just noticed different name)

most fans are 80mm, northbridge fans are 40mm... you need to measure the fan you want to replace, the box around it should be _cm in both directions, this will tell you what fan you want to buy.

here's a good source for fans...
http://www.xoxide.com/casefans.html


although, for what it's worth, if you just take the fans off, and go to a computer store, they should still be able to set you up with suitable replacements, and fans are generally cheap.

i treat fans like light bulbs, when in doubt, change it out. (although sometimes i peel the sticker on the back of the fan, and drip a single drop of oil onto the end of the shaft. this usually shuts them up long enough for me to gather money for new ones.)
