How do you change cpu fan speeds?

Recommended Posts

How can I change the cpu fan speed ? I looked in my motherboard bios but couldn't find anything ):

 

Mobo: Asus p8 z77 v pro 

Are the Fans are PWM?

It should be in the bios somewhere, but more so it depends on what sort of fans you have and if the fan connections are pwm or not. If you are using 3 pin fans, you either should get pwm (4-pin) fans, or get a fan controller.

According to the information, you should be able to monitor and adjust. But look into your fan types and connections. Your hardware (not the mobo) might be the limiting factor, not the software.

Use the Asus Fan Xpert 2 utility. If it is not installed, it can be found on the Asus CD that came with the motherboard.


80+ ratings certify electrical efficiency. Not quality.

i looked in all the tabs, only thing i saw in the monitoring tab was to set fans to turbo ?

If you want to control your fan speeds, just change the setting from Turbo to Manual.

You shouldn't change the CPU fan speed otherwise it could cause the CPU to throttle

even if i wanna bump the speeds way up? I feel like the fan running too slow right now

Ok no issues hardware wise.

You just need to be able to set it to manual, make sure you click the button on the type right that signifies whether it is pwm or not. Regardless of if done in BIOS, or if you use @brob 's suggestion, make sure you select that pwm, otherwise it will try to control speed through voltage, which can damage those noctuas.

If you want to control your fan speeds, just change the setting from Turbo to Manual.

Oh I found it! Which ones should I change

 

edit : i put the bottom two values to like 50, hopefully stuff doesnt explode 

 

http://i.imgur.com/M5Bqrlk.png seems to be running cooler than before, and not at like 500 rpm

Oh I found it! Which ones should I change

You still have the Q-fan on. I think you should leave it as it is, but if you want absolute control, turn it off and just force on the speed you want. 

 

Those values are:

CPU upper temp - The maximum desired temperature (70c is fine for 90% of cases, if your CPU is problematic temp-wise you might want to set it a tad lower)

CPU Fan Max - The speed of the fan at the maximum desired temperature. (obviously you want it to run at 100% speed at this point, duh!)

CPU lower temp - The temperature at which you want the fan to start rotating. (20c is fine. In a normal setup anything below room temp is fine)

CPU Fan min - The speed of the fan at the starting temperature. (20% is fine. Lower is more silent but at some point you run the risk of there not being enough torque to overcome the rest friction. That's why 20% is often the minimum)

 

In between those values it's a directly sliding scale.

I just gotta say, non-PWM fans can be controlled in BIOS too. The BIOS will just use lower voltage to run them slower whereas PWM fans get 12V all the time, just cut on and off rapidly. Even 2-wire fans can be controlled via lowering the operating voltage.

what does Q fan do? 

It's an automatic mode for the fans. It's an Asus thing. You set the min and max speeds and the min and max goal temperatures and it handles everything automatically in between them. The newer boards support more elaborate fan profiles but your board is linear scale. 

 

So if you disable it, you can only set one speed for the fan and it'll run at that speed until the cows come home, baring no mind to what the temps are. I think you should leave it on since I'd imagine you want your fans to run slower if the temps allow it.

Of course I already mentioned that, hence why I specifically noted the pwm vs non-pwm setting on my prior posts. If you try to control 4-pin pwm using voltage, it can damage the fans and it just isn't that effective. And trying to control 3-pin fans with pwm settings just doesn't work. There is also the question on fan hub connections on the mobo, but in this case, the pro mobo should have all fan connections pwm ready. Since he has Noctua fans with pwm support, all of those above points became null and void.

 

In the end, just make sure the Asus bios recognize the fans as pwm and that it controls them as such.

I've never heard of pwm fans being damaged from voltage control and it has worked very effectively for me for years without burning anything out.  not saying you are wrong but I can't seem to find anything about that being the case.  I would LOVE to know if that is the case though   :)

Heard it mentioned a few times, and on manufacturers websites. It may be entirely brand based, fan model based, or just suppliers claiming it for the sake of removing liability if something actually happens. Either way, better lean more to the side of caution if you have the option to do so.
