CPU fan error and system shuts down. I have previously had the fan replaced, only to have the error occur a year later. Could the issue be mother board related? Also can you suggest where I can look for a replacement fan? Thx...

Re: HP 873N CPU fan error
Yes, It is possible to be a board problem much more likely to be a dust /dirt problem. I have not found anywhere to purchase the CPU fans by themselves.Would obve to be wrong on this one; seems that they are sold along with the heatsinks.
My favorate is :

Overheating When the CPU overheats then it will shut down (i.e. thermal overload) and won't boot up again until it has cooled down. If this is the problem is not fixed then the CPU will eventually fail. A faulty fan causes the problem or the fan and heat sink assembly are clogged with dust. Check the CPU fan to see if it spins freely, if not replace the fan. If the fan and heat sink is clogged with dust the remove the dust and make sure the vents are clear and dust free. Use a small brush and can of compressed air to do this.

that can be meaning if the processor is Not Supported with your motherboard,or the New Processor is not in good condition (can be Over Heat or damage). Processor over heat or damage can be because the HEAT SINK (white or grey pasta at the top of processor) is not enaugh to cooling the processor or,the fan Proseccor is Dirty.
Without a proper working cpu fan the cpu will overheat and shut the computer down... if not fry the cpu. You will need to replace the cpu fan and hope the overheating didn't mess up the cpu or something on the motherboard.
You might have a cooling problem due to a fan malfunction. It is not clear whether it's the power supply fan or the CPU fan; in the latter case you might also have a thermal coupling problem. The symptoms you describe certainly seem to point to such.
My advice would be to replace the fan (or the whole power supply; you might also want to purchase a "Silent Power" unit for quieter computing). If it's the CPU fan and you are comfortable with, or know anyone comfortable with a bit of PC servicing, you might want to also unmount the heat sink from the CPU and replace the thermal paste between CPU and heatsink. Clean the heat dissipator (the black metal grille over the heatsink) with hot water and a bit of soap and dry thoroughly, or wipe it energically with a dust brush, before mounting the new fan on it.
if it shows that ..there are 2 possibilities.....first the fan is out ..and you need to replace it ...or to fix ..if it is a fixable problem ...or you have to go to bios and click on the factory defaults...to get rid of any heat limits that the CPU may have in settings ... do not worry ...it is actually stoping cause by default if the fan do not work ....the computer is stoping to avoid over heating ... the same if it is in all functions ...and have a limitation of temperature...and it is set too low ...and gets to it quick ..and shuts downs... so ...first restore bios to factory defaults...and click f10 to store changes... if it still doing the same ...replace the fan cause it is damaged...
The fan is attached to the heat-sink and can be removed/unscrewed off the heatsink. Take the fan to the computer or elecronics hobby shop for a replacement fan.
The are after-market CPU heat-sink fan assemblies available (these usually provide better cooling than the original units), just remove the existing assembly and take it to your friendly computer shop for a suitable replacement.
The acer recovery software sometimes has it's glitches. The CD might be fine, its just the data that wa written to the disk @ time of recovery creation was corrupt at some point.
If your machine shuts down randomly there can be only 3 possible solutions to this one:
Your battery from your laptop has an issue. Try letting the laptop run on AC power ONLY.
Your CPU is overheating, caused by a broken or unresponsive CPU heat sink fan, which causes your pc to shutdown (will always auto- shutdown at a certain temperature to prevent damage to the CPU. Check if you can feel "air" coming out of your laptop, suppose to be a hatched outlet at the side or at the back or on the top cover.
You have a Virus that is shutting down the pc when it wants to. NO Operating system issue can cause your PC to shutdowb; only a virus can do that.
Summary, check your battery, check if your CPU fan is running, and make a virus scan (if the pc doesnt shut down). Remember to make a backup of your DATA, cause Acer (i dont think they will) don't do backups. Waranty on Acers is usually 3 years, depending on the country. So they should replace and repair, everything.
