Question about Computers & Internet
If you have added a larger hard drive or other components this has a large current draw on the power supply and will result in overheating.
The CPU also has as effect on the current draw on a power supply therefore a new power supply is warranted that is you will need to install a power supply that is either 500 watts or more to give the performance and current supply the components need. Also if you have a gaming machine or you use it as such most of the time then there is high CPU usage that will result in high heat dissipation.
There is a free download that will regulate the cpu fan speed if *********** board is compatible >>>> it is called "speed fan" If your PC is used a lot you will need to clean it frequently of dust. I also recommend large cooling fan be installed to dissipate the hot air inside the PC cabinet. ( example: 2 ( 220 cfm) for exhaust and intake to the cabinet.
I hope this helps. Have a great day!

All the measures (almost) are wrong. This could be either from the power supply or by fault of the motherboard (sometimes the sensors cause these errors). A multimeter (if available) could help you to check the +12Volt (between yellow and black wires) and +5Volt (between red and black wires) at any available power connector (these ones with the 4 pins for hard disks, dvds etc)
In case of a problem or clarification, don't hesitate to post me a reply before rejecting my answer.
If you are satisfied, accept my solution.
Thanks and regards

It is very hard to read the layout of your question there since it's all in one line... can you retype it / copy and paste it into individual lines for me? It does definitely sound like your power supply is either sending irregular voltage or the south-bridge on your motherboard is actually going bad.
If you ignore the error (your bios should let you do this) does the machine operate fine otherwise?
Please reply back with the voltages on their own lines and I can confirm, will try to continue to decipher here.

Unplug the coolant temperature sensor while the engine is running. This should cause the fans to turn on low then kick to high, IIRC.
Typically when the engine computer loses the signal from the coolant temp sensor, it just turns both fans on high so the engine will not overheat. Ultimately, the fan is controlled by the computer. When it receives a signal from the temp sensor that reads the appropriate temp, it turns the fan on. One easy option is to wire a switch to the cooling fan relay. Then you can turn it on and off when you need it. I would not recommend running the fan constantly. You will burn out the fan motor and you'll never get up to normal temp for your sensors.
Check for coolant level and bad motor.
However as far as the fans and "disconnecting them from the temp sensor"..... The fans DO NOT connect directly to the temp sensor. They connect to the PCM (computer). The PCM reads the coolant temp sensor, and determines when to turn on the fans. It also uses the coolant temperature to control several other functions, including the transition from "open loop" A/F ratio control to "closed loop" A/F ratio control. It uses the temp to set the idle speed on cold start. It uses the temp to determine the cold start fuel enrichment. If you run this way, your car will be hard to start, it will run excessively rich, wasting fuel, and possibly even damaging the engine by diluting the oil.
