Windows 7: Fans speed

Fans speed

Hello, I don't know if this is the right place to post it but here you have it.

The thing is my two custom fans are quite noisy. They're plugged in the motherboard so you'll be able to turn it down. They're using 12V each and 1350 RPM. Now, how to turn these down? Should I just turn 50% speed, and expect they ain't that noisy?
Screws are tight by the way.

The question is, should I turn down the RPM (if possible), or the Voltage to 6V if possible. I'm not familiar with BIOS, so please detail your guide

Cheers!

hi there
i would invest in a bay fan speed controller if you have a spare drive bay mine is a sunbeam it controls 4 fans with four knobs with led lights for each fan blue for high speed red for half speed as you turn the knob down/up the light will change color to let you no the speed. ebay is a good place to look you must have good shops in Denmark?

Quote:
4 channel rheobus is the ultimate in fan control. With the ability to variably alter the voltage to your exact specifications, this offers advantage to our line of switched baybus'. The LEDs supplied on this unit are ultra-bright blue, and red according to voltage being put through the channel. Low RPM is Red color, high RPM is Blue color, changes at 7V.

Don't forget that each channel can provide 20 total watts of output... so you are not limited to four fans on this unit. You can power as many fans as you want, as long as you do not exceed 20W per channel.

I could, of course.
But is it possible with it?

Is there any danger in doing this?
Will the RPM have 50% too?
How to recognize that it's the right fans (maybe checking on the RPM)? Because i'm not sure it'd tell you the Model - As it's a Yate Loon

Best Regards,
FredeGail.

leave the bios if you are not sure you don't want to damage anything, you can use software to called SpeedFan Download SpeedFan - Access temperature sensor in your computer

read the instructions on how to use it before you try it and see if you are comfortable with it

Quote:
If you need a tool that can change your computer's fan speeds, read the temperatures of your motherboard and your hard disk, read voltages and fan speeds and check the status of your hard disk using S.M.A.R.T. or SCSI attributes, then you came to the right place. SpeedFan is the software to go. It is fully configurable and you can create custom events to handle every situation in an automated way. SpeedFan works under Windows 9x, ME, NT, 2000, 2003, XP, Vista and Windows 7. SpeedFan works fine on 64 bit too. The relevant driver is now signed with my digital certificate. And this all costs you absolutely nothing!

SpeedFan allows you to have a deeper view of the status of your computer. Almost every computer includes support for hardware monitoring. Accessing digital temperature sensors is really useful. If you are trying to figure out why your pc hangs when under heavy load or after some hours of usage, SpeedFan might help you to find the real cause. Very often it is a poor power supply, or an improperly installed heatsink that lead to behaviours that we tend to associate with errors from the operating system, but that are not. SpeedFan automatically searches your computer for interesting chips: the hardware monitor chips. SpeedFan can expose voltages, fan speeds and temperatures. On rare occasions, the BIOS doesn't activate such features. SpeedFan tries to enable them as long as this is a safe thing to do. Not only the motherboard is searched, but also some video cards and almost every recent hard disk. SpeedFan can access status info from EIDE, SATA and even SCSI drives, showing, in a consistent way, internal data that can be used to diagnose current and future hard disk failures. This is known as S.M.A.R.T. (Self-Monitoring Analysis and Reporting Technology). At the lowest level, SpeedFan is a hardware monitor software that can access digital temperature sensors, but its main feature is that it can control fan speeds according to the temperatures inside your pc, thus reducing noise.

i use the manual fans with the controller because i feel more in control and not relying on software plus the controller looks good! i power mine from the psu.

when you tun the voltage down the rpm goes down visa/versa its the voltage that makes the speed so to speak.

thanks for the rep but lets get you happy with the fans!

Hi again FredeGail,

If we're talking about case fans and not the cpu fan, then this seems like a lot of hassle just to reduce noise. There's no need to plug case fans into the motherboard, so why not just get a couple quiet fans with really low RPM's, plug them directly into the PSU and call it a day? You could also see what these fans sound like not plugged into the board... which may be speeding them up unnecessarily?

good Fumz would save a lot of messing around with settings on the fan markings it tells you the db to give you a guide but its quite simple less speed less noise.

Hello
Your motherboard has headers for one power fan and two Chassis fans. The Chassis fan speed can be set to Standard, Silent and Turbo by enabling Chassis Q-Fan Control in the bios. Setting the speed to Silent should quiet things down a bit.
