Just replaced motherboard with BIOSTAR Group N61PC-M2S. About a month later fan is at a constant high speed. cpu temp is right around 35 degrees Celsius. Tried looking for bios update with no luck. Could this possibly fix my problem? If so where can i find it?

Re: Fan noisy at steady high speed
Try replacing the cpu fan. The reason why the cpu fan is noisy its because the bearings are rusty and need some lubricants. But in this case you have to replace them. For me there's no need to upgrade your bios. Its just a hardware problem.

must be the pulse width modulator (PWM) circuits that control the fan, I'm afraid there's nothing you can do with that unless you work for the manufacturer, but you can get converters so that you can hook the fans up to the power supply, this should be a good fix until you get a new board!
Some fans are temperature-sensitive, i.e., when the CPU is "hot", the fan spins at high-speed, with more noise. For other fans, you can restart your computer, and enter BIOS SETUP, and set the speed of the fan, e.g., 50% or 70%, to make it quieter.
More likely is that the computer cpu is overheating and the motherboard is ramping up the cpu fan speed to try to cool it, hence the high fan speed and consequent noise. This usually happens when the heat sink is clogged with a lot of dust. It could just be that the fan heat sink came loose.
It may be that it's just a noisy fan, in which case replace it with one that doesn't make as much noise.
The CPU fan is designed to run constantly to prevent the CPU from overheating. The speed depends on temperature condition of the room; slow in cold and fast in a hot room. However if you suspect that it runs too fast them try re-seating the CPU. WARNING: Re-seating should only be done if you are know how to do; don't experiment.
If it is running noisy, you can apply one or two drops of machine oil to the fan's spindle.
Other reasonsinclude deposits of dust; use a blower to remove dust from the heat-sink.
To make sure you CPU is not in a critical state, log in the BIOS and in the hardware monitoring tab check the CPU temperature. It should be near 60 deg Celsius or 140 Fahrenheit.
One thing more, do not apply thermal grease in excess; its a conductive compound and can short the motherboard if it melts and deposits on the motherboard due to high CPU temperature.
On my computer when I first power up the display screen gives me the main board details and an option to change settings on it by pressing an F Key. Does your computer do the same? If it does you should press the key and it will give you the options to control and alter things like fan speeds. Don't forget to check if dust or something else is causing the noise.
the problem is that the mother board you are now using has a 4th wire that sences cpu temp this allow the heat sink fan to change speed to get this to work correctly you will need to replace the fan with a 4 wire style. what is happening is your not getting a temp siginal back to motherboard so the fan controller think it hot and send full power to fan alll the time the stock fan in hp systems is not very good any way .Get a good heat sink and fan to fit your new board ebay has them very cheap 5.00 to 20.00 this will all so increase you system temp and all get the proper cooling when you really need it.
The CPU fan on the GX280 is a variable speed fan. It only runs as fast as necessary to keep the CPU cool. But the fan also has an rpm sensor built in that regulates it at 3000 rpm. If the sensor is going bad, it senses its running slower than 3000 rpm when its actually running faster and continues to speed up until its wide open. Thus the 'jet engine' sound. Replace the fan and that should do it. If by chance it doesn't, it gets more serious and likely a motherboard problem.
Yes. This sounds like a fan issue. The noise often comes from bearings failing within the fan. Also, a failing bearing can make things harder on the motor as it brings the fan up to speed. This is likely the reason that you see increased warnings during the fan speed check while booting because it comes to speed more slowly as bearing wear increases.
I give this a 90% chance that your CPU fan is causing the issue. Since a decent CPU fan will cost you ~$20 online, it's not much out of your pocket if you happen to uncover another culprit.
I'll keep an eye on this post. Let me know how things go.
You must buy a new CPU Fan. You can get them HERE or a zillion other places on the Internet. You need a Socket 939 type fan that will handle your cpu speed. If you need help installing it, it may be in the manual. You can read the manual by clicking on the picture of your MB at the top of this post and then scrolling down.
Check the speed of the fan in the BIOS and set it lower, although 58-63c is alright for a CPU (P4 is rated to go up to 70c) you might want to make sure that you have good air flow in your case to make sure the CPU doesn't overheat.
Usually you can find the fan control in the Advanced section of the BIOS.
You'll also want to check the specs of the fan that you have installed as that will tell you how loud it's supposed to be. You might have to get another fan with lower decibels if you want it to be quieter.
