I have an HP touchsmart IQ790uk, error message: cpu fan failed

I have an HP touchsmart IQ790uk, when turning on the computer I get the message - cpu fan failed, the computer will power down. It then shuts down. I have been trying to locate the CPU part number so I can get the cpu fan replaced, with no success and very little help from HP. Any ideas would be much appreciated. Thank you

You are out of luck my friend Hp must be the worst people on earth to buy a pc from i will never get a product from them again

it would seem that the fan you need is a sunon and they only made this fan for HP so you can only buy it from an HP registered seller and thier is only one that does this fan however you can not just buy the fan you must buy the whole cooling system and in the UK it will cost you £280 before VAT and shipping

phone this number 01925251697

they will give you all the info you need

good luck

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.

New case fan running but still getting error message system fan failed.


Did you try;

Power off, power unplugged to computer.
Press the Power On button, and hold it in. Hold for a count of 10 seconds.
Let go.

Do this procedure two more times.

Plug the computer back into power. WAIT 1 minute, turn the computer on.

This method clears CMOS Error Codes, and sets BIOS Setup back to the factory default settings.

Startup freezes and sleeps for 5-10 minutes


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.

Message tells me CPU fan has failed...how do I find another one to buy? this is on a 1Q-770 touch smart all in one PC


It's an I ('eye') Q 770.

With tact and diplomacy:

1) Do you know how to open this puppy up? How to remove the Access Covers?

2) Do you know about Anti-Static Precautions?

3) Do you have experience with working on laptops, or at least desktop computers?

Make a mistake here, and you'll have an expensive doorstop.

1A) How to Remove the Access Covers,

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01060928&tmp_track_link=ot_recdoc/c00858789/en_us/c01060928/loc:1&lc=en&dlc=en&cc=us&lang=en&product=3351220

More information can be obtained in the download (Free) manual - Parts Replacement Instructions.
But only a small modicum of info.

http://h10025.www1.hp.com/ewfrf/wc/manualCategory?lc=en&dlc=en&cc=us&lang=en&product=3351220&

Left-click on HP TouchSmart Desktop PCs - Parts Replacement Instructions.

{This is a PDF file. The computer you are on now has Adobe Reader on it, which uses PDF files. After you click on the above named link, you may see a blank page for a few seconds. The file is downloading in the background, please be patient }

{ Motherboard Specifications:
Not current to the stated problem, but could be a world of information for you in the future.

http://h10025.www1.hp.com/ewfrf/wc/document?docname=c00858789&lc=en&dlc=en&cc=us&product=3351220&lang=en#N1013 }

2A) Anti-Static Precautions:

Your body carries Static electricity.
Static will fry out (Short Circuit) the hardware components inside a computer.

Computer unplugged from power before you work on it. Also hold the Power On button in, and hold it in for a count of Five seconds.
Let go of the Power On button. Do this procedure 2 more times.

Haven't worked on the TouchSmart series of HP computers. Cannot tell you if the frame inside is made of Steel.
Experience in the computer repair business, and logic, dictates it is not.
I suspect the framework is Aluminum, as is used in laptops.

With a desktop computer you would make sure it is unplugged from power, then touch the metal frame of the open computer case, to relieve your body of Static. (Should you leave your computer in the middle of repair, touch the metal frame again upon your return)

With a laptop you should buy, and wear an ESD wrist strap. (Electro Static Discharge)
Connect the alligator clip to a good ground source. ( I use the metal frame of an empty desktop computer case)
An ESD wrist strap is also the best method for working on a desktop computer.

Therefore I recommend you buy, and wear an ESD wrist strap, when working on the IQ770. (Unplugged from power)
The average cost of an ESD wrist strap is around $6.

3A) With patience, and determination, you will replace the fan, and gain experience.
(Also as you have read there aren't that many techs, except at HP, that work on these babies. You may find your experience to benefit you, and others when someone has a problem with HP TouchSmart computers. JMHO)

I just did a search. Are you sitting DOWN?
$285.00 US dollars! REFURBISHED!

http://www.sparepartswarehouse.com/HP,TouchSmart,IQ700,Computer,Fans.aspx

I suggest you see if you can carefully open the fan shroud, (The casing around the fan), and find a fan/motor replacement.

Look at the markings on the label of the fan.
Post what you see.
The fan should run on 5 Volts DC, (5VDC), or 12 Volts DC, (12VDC)

Tell me how many wires, and the color code of the wires.
(Color of the insulation on the wires)

What RPM is listed? (Revolutions Per Minute)
Examples: 1000RPM. 1200RPM. 1500RPM
It may just list the number, and not have the designation RPM after it.
(The above numbers are just off the top of my head. the RPM's could be Much higher, or lower)

Measure across the fan blades, give me the Diameter. (Inches or Millimeters, or Centimeters)

http://en.wikipedia.org/wiki/Diameter

Measure the Width, or thickness of the fan blades.

Upon booting, I get a screen that says my CPU fan has failed. The PC is a hp touchsmart iq770. If I order a new fan, is it something that I can replace myself....or do I need an experienced technician?


If you go to a computer shop and you can tell them wich type of motherboard and or cpu you have, they can give you the cpu fan you need. The replacement is easy but it depends on wich cpu you have. First of all i would check the power connection cable of you cpu fan to your motherboard. Are you sure the fan doens't turn any more?

When i boot up the laptop i get a message 'Main Fan Error' the fan runs on start up then stops just before i get the error message. Fan will not restart... Joseph


Hi,

This message means that the fan on your CPU (processor) is failing or has failed. This is not good because if the fan on the CPU fails your CPU will overheat and cause your machine to lock up and become non-functional till it cools down and then the same cycle will repeat till the fan is replaced.

Let me know,if needed further assistance.

Hope i helped you.

Thanks for using ' Fixya ' and have a nice day!!

Error message shuts computer at start up...CPU fan failed. HP Pavilion M8400 F Phenom X49500 2.2 GHz (computer is new to me)


the trick is that there is more than one spot where you can plug in the CPU fan, had the same issue with an HP myself. try a different spot to plug in the CPU cooler. mine was in the upper right hand of the board and was labeled CFAN. the one i thought was for the CPU (it was same color as the fan connector) was actually a case fan connection.

CPU Fan Failed


Yes that is what you need to do. It's either due to your CPU board having issues or your fan is just old and needs to be replaced. You always need to have a fan running to cool off your CPU. Let me know if this helps and if you need anything else.
