Any tools to control a CPU Fan speed ?

[Zenoth]

If it matters to mention, my system's main specs are in my sig.

So, it there a software that'd allow me to control my CPU Fan speed ?

Thanks.

Speed fan? Any options in the BIOS?

 

[jkresh]

Asus board should almost definitely have cpu fan control options, set by temperature. I generally prefer using a fan controller for all fans (even if I use an hsf for the cpu) simply because it allows for more control then any software.

 

[Auric]

SpeedFan uber alles. And disable any such onboard functions as they are invariably lacking in comparison.

 

[Zenoth]

Ok, I've tried SpeedFan and ASUS PC Probe II, both don't work.

They both detect my fans and some temperatures, and I can set a few speeds, but it just doesn't actually work. Each time the CPU hits 50ºC+ the fan goes on full speed and the noise is so loud that it gets over my games and I can't hear a thing, very annoying, irritating and distracting from gaming experience.

I think there is something called Q-Fan in my BIOS, if that's Enabled then would it interfere with SpeedFan ? I think it has always been Enabled, or else the CPU fan would always run at high speeds. Summer is here now, we get hot temperatures, so it takes nothing more than a mere game start to hear the CPU fan all over the house (well, not that much but I can still hear it with my side panels on, and me outside of my room while the door is closed, so ... yeah).

i got the cheap, non sli, non sata2 version of that m/b, in fact 2, and in the bios there is an option to allow the bios to control the fan speeds

 

[Zenoth]

Yes, I noticed that, it's Q-Fan. But all that it allows to is that I can set a CPU temperature threshold at which the fan will suddenly start spinning full speed non-stop at around 5500 RPM or something like that, it's spinning to its maximum potential, it can't go any higher, and the noise is extremely loud. If, on the other hand, I disable Q-Fan (I just tried a few minutes ago), then the fan spins at around 95% speed all the time, again still very noisy.

However right now I think I managed to make SpeedFan work properly. I'm still not 100% sure though, I'll have to run a couple of seconds or minutes of Prime95 just to load the CPU at full and see how the fan speed goes while the temperatures are rising above the threshold set by Q-Fan in the BIOS.

 

[Zenoth]

DARN ... that bloody fan of a b ... grrrrrrrrr.

Ok guys I need serious help. Either I control the speed SOMEHOW, or I just throw it outta the window.

 

[bob4432]

what hsf are you using?

on both of my 939 x2s i have a zalman 7000 copper hs that has the 92mm fan in it. it is pretty quiet on both rigs.

 

[Zenoth]

It's the stock one.

 

[bob4432]

sorry, i have never run the stock one, but i can definately say that the zalman units are nice and quiet and cool good. i use to run my 3800 @ 2.5GHz no issues, and that wasn't even pushing it. if i were you i would put a WTB thread up in the fs/ft section, that is what i did and got my 2nd zalman 7000cu for an exceptional price

 

[Zenoth]

I just bought a GTS last Saturday and I got no money left for PC parts for months. All I need, all I want, is a freakin' software capable of controlling the fan speeds and not just detect the temperatures. So far ASUS PC Probe II and SpeedFan don't work, that's with and without Q-Fan, doesn't matter what I try, the stupid fan spins 100% non-stop.

 

[lxskllr]

You don't have $17 for a hardware fan controller? That would be the easiest way to customize fan speed.

 

[Zenoth]

Yes, I do have the money ...

I mean, not right now, I don't want to spend too much right away. It's just that we suddenly got two hot days in a row over here, and while gaming the CPU temp increased much faster than usual. That stock cooler has always done the job in terms of cooling efficiency, it's just loud, very loud, at 100% speed. And I installed some AS5 paste, which helps a little over the default one (which I removed with some 93% alcohol if I remember correctly). The problem is just the noise. I might get myself a Zalman cooler for it, or not ... I don't know, because I am planning to upgrade the CPU, Mobo and Memory sometime later this summer, or early during autumn.

Meanwhile I think I'll just increase the threshold in Q-Fan. Lowest is 51ºC at which it will kick in. Highest is 80ºC I believe. Of course I won't set it at 80ºC, but I was thinking around 60ºC or 65ºC ? What is a "safe high" temp for an X2 ? Or a CPU in general ? Can it operate at around 65ºC to 70ºC without damaging it permanently ? I know GPUs can sustain some tremendous heat for long periods without failing, and I do know that it's "different" for CPU, but at what extent I don't know.

 

[bob4432]

my gpu gets to 70C, i wouldn't want my x2 to get that hot. it is probably running @ 100% because it needs to

 

[Maximilian]

Shouldnt be over 60*C, low-mid 50's is ok. Now saying itll break or anything, but its generally a good idea to keep it under 60*C.

 

[Zenoth]

I see ... oh well.

I'll set it to something more reasonable like 54ºC.

 

[IdaGno]

For those hot days & until you can afford a baybus fan control unit, or better yet, a quality aftermarket CPU cooler, is it possible, the way you're set up, to remove the PC side panel & aim a small desktop fan in there? I'm sure that would help cool things down, but may not be a whole lot quieter.

(please don't throw it out the window!)

Yes, it's called a rheostat.

Software would depend on having appropriate hardware. Some motherboards (I think MSI, Gigabyte, and possibly ASUS) will controll the fans. My Intel Brand socket 478 Motherboard automatically controls fan speeds on demand.


Otherwise you are best off with a high powered 50 watt rheostat and daisy chain all your fans on one circuit.

In general, I've found that if you can't get speedfan to work, you're not going to be able to get the fan control through any software (other than the mobo manufacturer's) that you want through the motherboard plug.

I've got my cpu heatsink on a sunbeam rheobus, and split out the RPM wire to plug into the cpu fan header. That way I have manual control over the fan and can also read the speeds.

If/when you want to spend the money to control your fans via software, check these out:
