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.
It appears you have a faulty CPU fan and it is causing the CPU to overheat and shut down. I suggest you replace the CPU fan. remove any dust from the heatsink and put new heatsink compound on the CPU/heatsink.
1. First of all Remove dust from your CPU fan and try again if issue has been not resolve 2. Second test your SMPS by the help of Green & Red wire. In case fan is turning properly it mines your SMPS is ok 3. Third & last kindly replace your SMPS For the same.
Does the new fan have 2 wires or 3 wires?
The 3rd wire transmits the speed (RPM -- revolutions per minute) of the fan.
If the HP motherboard does not detect the "status" from the fan, then you get a "fan error".
Are there 2 places on the motherboard, close to the CPU, where the 3 wires COULD connect? If there are 2 places, connect the 3 wires to the OTHER connector, which should be labelled "CPU FAN".
First make sure that the CPU fan is properly connected to the motherboard. There is a connector on the motherboard that is usually labeled CPU_FAN.
If the fan is properly connected, but isn't working, a replacement can be purchased for a reasonable price. Check with Gateway or your local computer supply shop and they will be able to help you find the right fan assembly for your CPU.
Hope this helps. Please take a moment to rate this solution. Thanks.
you have to do exactly what the system is saying Your CPU fan connector is loose or there is a problem with your CPU fan if You are well-versed with the hardware part of the system you can do it yourself Or call Your PC administrator or who repair Your PC
The cpu fan has a three wire connector that connects to the mother board. Usually located to the right & up from the cpu. If yours is connected currently the wires may be miss aligned. From left to right the pins are: first pin ground/Black; middle pin 12v./Red & last pin rotation/Blue. There may be a bios update that address this issue. Dell does not give up information easly.
First, download PC Wizard 2008 so you can check the fan speeds and temp of your CPU (and every other component of your PC if need be) and see if it's operating properly. You can find it here: http://pc-wizard-2008.en.softonic.com/ If it's malfunctioning, you'll need to replace it.
