I have an H8DAE-0 board installed in my system and the fans will come on for a few seconds and then stop. I checked the BIOS and it is set for continuous fan power. The fans only kick in when the system is starting to overheat (72C) and then stop right afterwards. Lowering the overheat temperature is not an option.
I have another system with the same components and its fans run all the time. I have double-checked the power connections and all the fans are plugged in independently so I don't think the fans themselves are an issue. There are stand-offs under the board so I'm fairly sure that it's not a short happening under the board. Any suggestions are greatly appreciated.

Re: H8DAE-0 Fan issues, stopping and starting.
Sounds as if you have a motherboard fault or a processor fault, as, if the processor is faulty, everything will stop, especially if the temperatures arent being read correctly by the motherboard causing the system to shut down before any damage is done..
It's a process of illimination i'm afraid

Make sure you have the cable that plugs into the back of the computer from the monitor screwed in tight. Also make sure the cable on the back of the monitor is screwed in tight and also that the power cord on the back of the monitor is pushed in all the way.
I'm almost certain you're not in standby mode. Does the computer stay on when you get the no signal message? Do you hear the fan blowing, do you hear the disk drive spinning? If not, I think your system has completely shut down. I'm thinking maybe a virus or some hardware/software conflict is stopping it from completing the boot cycle.
Try getting into the Bios or System Setup to see if the LCD Stays on and the computer stays on. Turn the computer off, then hit the power button to turn it back on. Look at the lcd screen and it will tell you what key to hit to go into the Bios or System Setup. Go into it and let the computer sit for 10 minutes or so to see if it shuts itself off.
If you are successful with the computer staying in the Bios or System Setup lets try getting into Safe Mode and see what happens. Turn the computer off and hit the power button to turn it back on and immediately start hitting the F8 key repeatedly until you see the SAFE MODE option. Select the Safe Mode option and let the system boot up. Safe mode will look different to you. The icons will be bigger and the lcd screen darker, but that's normal. If you are able to see the desktop in safe mode just try opening up MS Word and maybe let it sit for a few minutes to see if it shuts off.
If safe mode was successful, then try booting it normally. If it fails, we know we've got an issue.
hi, enter tech/rep. utility/counter/stop 0 0 stop 0 1. touch system 2 , touch option board status, touch set of fax main, touch end once, touch system 1, touch marketing area, touch fax target, select country code, touch end twice, touch fax, touch initialization, touch fax function parameter and communication journal data , touch yes twice, touch end, touch exit, turn main power off for 10 seconds.......done...good luck si
when the fan stops 2 things are happening 1 the bios sences no rpm speed from the fan or the processor heats up to quickly and the safety in the bios will shut it down. try moving the fan connector to the case fan connector then go into the bios and change the fan settings. this is only a temp fix the fan stopping tells me that the onboard cpu fan regulator is going out and this is a precurser to more problems to the board going out. also just to be certin check the power supply 4 years ago i came across this in a gateway it was weird.
When my system had a problem, it was the second fan! My board not only had a processor fan but it also had a very small bios fan. If either fan slows down, the system will shut down. Also, check and make sure that you are using the correct jack for your fan. It sounds dumb but most newer boards has multiple jacks for fans. If you are sure that you are using the correct jack and you are using a fan with 3 wires, not 2 (3 wire fans has a ground, positive 5 volts and a sensor wire to tell the board the speed of the fan) then you have a major problem. Your motherboard has a circuit that is designed to prevent the system from running without proper cooling. Even with a new fan, if the circuit is malfunctioning -- YOUR DONE. Unless your bios gives you the option of bypassing this safety feature, you will need to replace the motherboard which is another bag of worms. Even if you buy the same board and install it, most of the time the system will lock up during boot because of some slight difference in the new board. Sorry for the bad news. Just make sure that you have the 25 digit number for your operating system so that you can reinstall Windows. It should be stuck on the computer case. With that you can replace the board, reinstall Windows and re-register with Microsoft. That way you can download the over 90 updates needed with XP (assuming that you are using XP). Good Luck
brand and type of ur mobo, in moust of the time a restore to factory defaults is the solution, or go to hardware monitor and disable the fan speed sensor, or check on the mobo that the cpu fan conector is in the right place, if this will not fix le't me to know
