It means the 3 pins for that fan are not working on motherboard . I suggest you use the motherboard 3 pins for the chasis fan and buy a CPU fan with 4 pin setting that connects to your power supply ( much better current )

I had the same problem out of the blue. One day I tried to power up and I got the same error. I don't know if this is a fix, but all you need to do is press F1 and you are on your way. My fan is working fine!!

What makes 511-cpu fan not detected and 512-chassis not detected


Are you seeing this error on a system you built or a pre-built system? If it is a pre-built system, check that the fans are running. Next check where the fans are plugged in, the CPU fan must be connected to the CPU fan connector on your motherboard. The chassis (rear case fan) only needs to be connected to the motherboard if you want the monitoring/PWM (modulated fan speed) option. If your CPU fan is powered directly from the power supply, change this.

If this is a system you built or recently updated the case, check your fan power connections, as above. Next check the fan speed. My ASUS board will give the "CPU fan not detected" error if the CPU fan speed is too slow. A different CPU fan will solve the problem. (I got my fan with the CPU; it works fine.)

I hope this helps. Please add a comment with more information about your system for more assistance.

Compaq Evo will not start

Test your PSU power supply unit or replace it if your power supply units fan is not working your PSU is faulty

http://pcsupport.about.com/od/toolsofthetrade/f/powersupplytest.htm



One bad lead can cause a computer to continue on a cycle of restarting or to shutdown or fail to detect/ boot up a computer hard drive



Test all leads that attach to your hard drive power and data cables IDE SATA

the leads from your MOTHERBOARD TO YOUR HARD DRIVE make sure they have a secure dust free connections and are not faulty or just replace them they could be faulty


make sure all leads that are attached to your dvd\cd floppy drives have secure connections and are not faulty or just replace them they could be faulty


computers need power and data to travel through every working device to continue its cycle and have an end so any faulty leads will end up with a computer error


even something as small as a faulty electrical or fan lead can cause you problems



motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive if its a flat ribbon 40 pin type IDE replace it this will be the first to fail



check all electrical power input and extensions make sure they are securely seated even the cd/dvd floppy drives need to have current go through make sure these drives are working



also check the Cmos battery and computer RAM modules make sure they are securely seated with no dust built up or in the sockets on some motherboards cmos batteries are soldered in


check you CPU central processing unit make sure its securely seated and has thermal paste it might be getting to hot the thermal paste will help disperse the heat

Thermal compound is a sticky paste that is placed directly onto the CPU.


Allowing for a more direct heat transfer between the CPU and HEAT SINK and preventing air gaps from forming between the CPU and heat sink.

hope this helps

When i put on my computer, this message apear : 511-cpu fan not detected. I have a Compaq Evo D510 CMT and i use Windows Xp. Thaks for the help


This will likely be caused by a loose connection, if you look inside the machine there should be a cable running from the fan on top of your cpu to the motherboard. If thats disconnected or loose then plug it back in and all should be right with the world!
