What causes ASUS A8N SLI Deluxe chipset fan and RAID failure
I have experienced three chipset fan failures, on one occasion the control software shut it down.
Last March my chipset fan started screaching again. In despair I pushed the impeller back into position using a retracted ball point pen, but now it can take ages to get to full speed on start up. Occasionally I get a warning message about this in BIOS, on start up.
What is so different about this fan, that it fails. Is the motor's lateral movement caused by electro-magnetic forces, and what is supposed to hold it together, but obviously does not?
My retailer wants the motherboard replaced, but last time they took one month to do it (MESH COMPUTERS).
They refuse to fit the latest version, the A8N32 SLI Deluxe, insisting on like-to-like.
I hear that ASUS has a new chipset fan design.
Where can I find details of my chipset fan on the Internet, and the latest version?

Here is the manual for your motherboard (since describing a diagram probably isn't very useful...) http://dlcdnet.asus.com/pub/ASUS/mb/socket939/A8N-SLI/e2024_a8n-sli.pdf
You want to look at pages 27-35, they describe what you need to plug into the motherboard. Basically make sure you have connected:
1) 24-pin power cable (from power supply) 2) 4-pin power cable (for CPU from power supply) 3) Any case fans with 3/4 pin connectors. 3) hard drives (SATA or IDE) 4) USB front panel ports 5) Audio front panel ports 6) Case plugs (power LED, hdd LED, power switch, and reset switch).
You can research *********** board and drivers at ASUS.com.
You may find a new BIOS update which controls the fan speeds and temp.
If not, you can find plenty of frreware which will handle *********** board.
If you installed total 4GB memory, the system will detect less than 4GB of total memory because of address space allocation for other critical functions, such as:
- System BIOS (including motherboard, add-on cards, etc..) - Motherboards resources - Memory mapped I/O - configuration for AGP/PCI-Ex/PCI - Other memory allocations for PCI devices
Different onboard devices and different add-on cards (devices) will result of different total memory size. e.g. more PCI cards installed will require more memory resources, resulting of less memory free for other uses.
On a SLI system, since PCI-Ex graphic cards will occupy around 256MB, another 256MB will be occupied after you install a 2nd PCI-Ex graphic card. Hence, 2.75GB memory left only if two SLI cards installed on A8N-SLI Premium while 3.0GB memory left with one graphic card without other add-on devices.
This limitation applies to most chipsets & Microsoft Windows 32-bit version operating systems.
If you install Windows 32-bit version operating system, we recommend that you install less than 3GB of total memory. If more than 3GB memory is required for your system, then below two conditions must be met:1. The memory controller which supports memory swap functionality is used. Chipsets later than Intel 975X, 955X, Nvidia NF4 SLI Intel Edition, Nvidia NF4 SLI X16, and AMD K8 CPU architecture support memory swap function.2. Windows 64-bit OS which can address more than 4GB memory.
It sounds like the front panel wire has either come loose from the motherboard or is plugged into the wrong spot. Recheck the motherboard to see if the wires are in the right place & not loose. Hope this helps.
Here is the link to buy a new replacement chipset fan: http://estore.asus.com/shop/category.asp?catid=131
You'll need to become a member & sign into Asus to order a new chipset fan or you can call Asus directly. I know there are four black pins with tiny springs on the back side of the board under the fan. Its been so long since I changed one of these. It may be best to wait until the new one comes in before removing the bad one. Another option would be to call Asus tech at 1-812-282-2787 IL M-F 8-5:00PM EST and ask for "How to remove fan" from a tech.
Or you can buy a better chipset fan that will last longer & cool far greater than Asus fan.
