Anyway, I hope that's elaborate enough about my specs. The motherboard is a ASUS M4A785-M and everything else is pretty much stock from a eMachines ET1331g-05w. The heatsink fan has been making some incredibly loud noises and I noticed some performance issues since I installed the new motherboard.
GPU NOS can't start because my CPU is in overclocking mode and I don't know how to disable that...
How can I fix this? I don't know anything about overclocking, really.
CPU Overclocking: Manual
CPU/HT Reference Clock (MHz): 200
To say AUTO
Cool 'n' Quiet: Disabled
To say ENABLED
After doing that and rebooting, your system will be at stock settings and the heatsink fan will be quiet. And if you can't figure out how to change the value to AUTO and ENABLED, it is pretty easy. Just select the MANUAL and hit enter then use the arrow keys to select AUTO. Then the same for the Cool n Quiet. Just select the DISABLED with the arrow keys, hit enter, then select ENABLED. Then upon exiting the BIOS remember to save changes. Everything will be normal then.
First check to make sure no wires are hitting the fan blades, then measure the width of your case from the motherboard to the far side of the case, and you'll get some recommendations on a new HSF. I'm assuming that with your CPU you could go completely fanless pretty easily if you have the case width (unlikely) or are willing to cut out a section of your case.
I don't think he needs a new heatsink fan because those temps there are in F, not C. His CPU temp is fine, but the FAN RPM is too high. Just needs to enable Cool n Quiet and the fan will not be so noisy.
I don't think it's a dying fan unless it is clogged with dust. I have a stock fan on my x4 965 and if I disable cool n quiet then it sounds like a jet engine. When I enable cool n quiet then it is very quiet unless I play games for a long time then it gets louder.
And as for your performance issues, your CPU temp is low and it's not the cause. Since all the overclocking things are set to manual, you might have a bad setting somewhere and it is reducing your performance. By setting everything to AUTO, it should correct most issues.
Also, to make the CPU run cooler at idle states, make sure you Enable the C1E support too. And look in your BIOS for the memory settings and make sure they are set to AUTO as well. Then everything will be setup and running smooth. If the overclocking is manual and the frequencies are wrong it will have problems, if the memory mode is manual and the timings and speed is wrong, then you will have problems. By setting everything to AUTO, Enabling Cool n Quiet and C1E support... your computer will run quieter and be more stable.
There is no reason to adjust any off the settings you have there unless you are into overclocking and know the consequences of each change and how they effect performance and other system components.
Is that fan dirty? Did you reapply thermal paste adequately? If the fan is dirty it will run faster. If the thermal paste isn't great the BIOS might think the CPU is hotter than it really is and adjust the fanspeed to max to compensate.
Perhaps it is just time to change the heatsink fan to an aftermarket one.
Only if the PSU fan is what is loud. Your CPU fan will not be louder because of the PSU.
Also, changing from one board to another won't increase fan speed also unless it isn't mounted well. Take off the side panel, turn the computer on, then roll up an old newspaper or magazine. Stick it to your ear and listen around inside the case. See if the loudest noise is the PSU, CPU or GPU. Then you will know where the problem lies.
If the CPU fan is not dirty and the heatsink is mounted properly, cool n quiet are enabled and the CPU fan is the loudest thing in your case, then try to find an aftermarket CPU with a large fan and heat pipes. But if the most noise is coming from your PSU or GPU, then you have other fans to clean.
^ Make sure the CPU fan is plugged into the CPU fan plug and not the case fan plug. Also make sure it's not plugged in backwards or something. If it is getting constant power then it will always be full speed.
