regular speed fan cpu

[gil]

My pc is quiet enough, but the cpu fan makes you feel. I would like to be able to adjust the speed of the fan.
the motherboard is a gigabyte z77x-d3h and the heatsink is a master cooler hyper tx3/101. card is fan have 4 pin connector, which made me think I can adjust the speed via software.

I downloaded a gigabyte program, but it conflicts with windows 7, just click on the start button to cause the restart of the pc.
:36_1_3:

then I tried with other free tools randomly taken over the internet. Some do not seem to work, (they do not detect the fan of the cpu or do not slow it down) others have such a daunting interface, which I gave up to avoid problems.

Does anyone have any suggestions?

hi, strange, usually the 4-pole fans (pwm) are silent in idle and they only make themselves felt for supported workloads.
I knew a little program called speedfan. Maybe you could use it.

On the other hand, I would assure myself two physical things: presence of a lot of dust between the fins of the heatsink or in the fan, quality/state of contact between the heatsink and processor (e.g. thermoconductive paste). in the past similar inefficiencies had raised a lot the speed of my pwm fan.
Finally, keep in mind that some bios (e.g. those for supermicro server case fans) or the internal chips to the fans (suitable to make them work in pwm), start from rpm not as low as a minimum value. so they also make you feel at rest cpu.

In summary, I:
-I would check dust and dissipation contact
- I'd read the number of bios cpu idle turns
- I'd take my consideration and then think about a program like speefan.

I hope I was useful.

I always keep the computer clean in a manic way.
It is not noisy in absolute terms, but it never settles.
I'll try to study the bios. I've already looked at it, but I couldn't understand having to put my hand.

It is not noisy in absolute terms, but it never settles.

You're right.

read first in the bios the rpm indications of the fans. They are usually found in a section that could be called "monitor sisema" (in Italian.. but bios is written in English ); there should be both fan speeds, and the temperature and tension of the system.

the program that I indicated to you, provides you with a reading of these values precisely linked with the bios or to the sensors of the motherboard (I am not hardware in the matter). Then, you can decide whether to intervene or not.

in some cases, you could also bypass the pwm system, take from the pins on the motherboard right tension and ground (2 pin) signal number turns and leave the fourth pin open (pwm). then bring these three pins to an additional circuit (which feeds on hd connectors) and there with a trimmer adjust the pwm to the cascade fan: manually or with an additional temperature sensor.

all this is usually done for those fans (mother cards) that are not 4 pin pwm.
the patterns, as well as the circuits already made, you find them easily online.

Ultimately, it is not necessary to underestimate the invoice and the fin profile of the fans. Both can make a difference in db between an economic fan and a high moth. :smile:

Hi.

I have a uefi bios version f9. this voice to adjust the fans just can't find it.

 

[Andalo]

In fact it would have been better to ask you immediately the features of your hardware.
Unfortunately, I have no such bios (which is no longer a real bios), but you may see if there are options like:
system information
device health status
You could find the answer here.
otherwise try with the software I told you.

Hi.

 

[gil]

I threw out the configurations of the motherboard without running it. I can't find anything that looks good for purpose.
sin

 

[Andalo]

Hi, I'm sorry. However, it indicates below that machine model uses (in case of laptop) or motherboard brand/model/version; Maybe I can find something.
Have you tried speedfan to read this information?
Hi.

 

[gil]

via this video I managed to change the speed of the fan from uefi on my hardware that as written at first the motherboard is a gigabyte z77x-d3h and the heatsink is a cooler master hyper tx3/101. https://www.youtube.com/watch?v=ouo5qhhw44wfrom uefi the settings are limited, there are several options to increase the speed of the fans, but only one to reduce it. with "silent" configuration I reduced the rotation of about 10%. from the noise you notice little.
However there was an option that seems to enable the use of pwm, perhaps for this reason the software did not work. Now I'll try

hi, writing fast, while having read the first time the details of your card, had passed my mind and read only the last answers:tongue:
I downloaded the manual of your mobo, and in fact there is a section in m.i.t where you find the pwm phase control. I think that's what you're looking for.
the manual is clear about: pg 43-47.
remains at this point to see if the speed reductions that allows you in the various settings set, are such as to satisfy you.
For example, in my supermicro card, there is this option from bios, but the reduction is so exigeous that the noise (we talk about a server case that has a number of pwm fans (cse-743tq) makes you feel much more.
If this is also your case (I hope not), there is only the solution I indicated at the beginning.
that is to break between the connections to 4 poles on the motherboard and the same fans, a circuit that can further reduce the pwm signal (or better than to radiate the impulse of "lighted fan" in the unit of time.
This is in fact the way of working the pwm system: it does not lower the tension, but it sends more or less thinned signals of on.

such circuits, as I told you, also serve to convert non-pwm connections (three poles) to pwm: they are their ceh manage according to temperatures or values you set, the on/off signal to the fans.

However, I hope that there will be a satisfactory impetus for you among the various.

Let me know.

Hi.

as from previous message to your

from uefi the settings are limited, there are several options to increase the speed of the fans, but only one to reduce it. with "silent" configuration I reduced the rotation of about 10%. from the noise you notice little.

programs like speed fun keep not working, maybe it's my fault that I can't use them.

hi, not seeing in person what you can see with the monitor before, unfortunately I can not understand perfectly what degrees of freedom you leave your uefi bios.
If you can't further limit rpm, then you're probably in the case of my supermicro: That's the least.

would not remain that the alternatives (if this is your case) to use external software (if you can't by yourself I recommend asking someone who can see the monitor in person while performing tests) or a circuit made specifically for the purpose.

for the last case, you can do research with "power pulse modulator". for example there are practical systems to be inserted directly into the dvd/cd housing; below a link that clarifies:

Hi.

thanks to all for useful advice. Hi.
