Re: main cpu fan high speed

The speed of the cpu fan will go up and down depending on the work load that your pc is going thru,lets say you start a game and the speed increases then drops down thats all normal

Had my motherboard changed by local repair shop. Both fans are now running constantly & it is deafening, also power light no longer comes on and was told it was "no big deal". Have 2 like computers,...

Ok so what fans? the case fans? the cpu fan? The power supply fan should always run. The case fan can be wired to the mother board and do an speed step system (slow to fast) depending on heat, same with cpu fan. As for the power light its just an matter of pluging in the wire from frount panel to the mother board pins for pwrled. Asus has an download for your board to get the pin outs.

Cpu fan runs at high speed all the time

the problem is that the mother board you are now using has a 4th wire that sences cpu temp this allow the heat sink fan to change speed to get this to work correctly you will need to replace the fan with a 4 wire style. what is happening is your not getting a temp siginal back to motherboard so the fan controller think it hot and send full power to fan alll the time the stock fan in hp systems is not very good any way .Get a good heat sink and fan to fit your new board ebay has them very cheap 5.00 to 20.00 this will all so increase you system temp and all get the proper cooling when you really need it.

I have an asus a7n8x-la mother board. It ran fine except the cpu cooling fan would speed up and the cpu heat sinc was very warm as compared to others. Finally it would not boot or go to post with the beep....

First of all set the BIOS default.
i think somebody change your Bios settings like-- over clocking or speeding fan etc etc.
add comment for further assistance.
Good Luck!

Most likely problem is an unsuppoterd cpu. Check the Asus website to see if cpu you installed is compatible with this board.

Motherboard problem

Chances are the CPU fan may be running too slow, dust & dirt build up under & over the fan blades can be a big factor. CPU fan could just be going. Are you over clocking the system. (IF so buy a better heatsink & fan for over clocking the system).
To check if CPU is getting too hot. Enter the bios & go to the title, "Power" page 2-28. Open Hardware monitor & check the CPU temp & mother board temp. (Make sure the case is closed in normal running conditions).

CMOS Checksum error - Defaults loaded

When the CPU speed stored in BIOS and the actuall speed of CPU differs then this error comes.

To fix this you have to select the actuall speed of your attached CPU to the board. Just set the actuall speed and save the changes. It will fix your problem.

This Is A Processor error Message, CPU ( Central-Processing-Unit ) INT ( Intermittent Fault ) wrong Type Installed. ( Faulty Processor ) Disconnected Fan-Wire To Motherboard ?
Or if It,s INIT Then It Fails To Initialise The CPU.
Is The Board Auto-detect Settings ? Or Jumpered ?

Msi 654e max atx mother board

If your manual states a max of 2.2GHZ then, take it as that, when your board was made the bios and bus speeds would be set at the maximum to run a 2.2GHZ, not a 3GHZ, also the heat sink and fan may not be enough to cool the processor. The only way that a 3GHZ would run was if you updated the bios and personally i would not recommend it. You would be better advised updating the board and processor as a package ot fitting more memory if the pc is not used for gaming or high end video editing.
