Chipset fan making lots of noise


Recommended Posts

As far as new fans, there is plenty of discussion here on that....there is the vantec option or the evercool vc-re (do a forum search for keyword "twinkling").

 

I'm interested in finding out more about this myself however. I'm trying to avoid replacing my chipset fan, due to it would be a pain to take everything apart AND I'm afraid of messing something up when I do it. SO, I know I can control the chipset fan through smart guardian - you can make it quiet enough by slowing the fan down a good deal. At defaults it sounds like a tiny hairdryer - keeps the chipset at about 40C and spins at 6250 rpm. By lowering the rpm you can pretty much silence it - of course the temp goes up. From what I've read here...the Chipset is safe up to 60C....so I'm thinking I can just turn the rpm to about 3000 and set the alarm to sound at 55C and avoid replacing it. Does anyone do this?

If you want to use the stock fan, just let it idle in bios awhile, and then set your chipset fan to come on full, one or two degree's higher than your idle temp. The stock fan will spin at 3000 rpm most of the time, and is quiet. The whining when it ramps up and down, will drive you nuts after a while though. Just try and get an acceptable mix between cs temps and how often it ramps up doing just ordinary things. Who cares if it ramps up to 6000 rpm and whines, when you're gaming. The stock fan does a decent job, if you can find the right balance.

That being said, the VC-RE is still worth the effort and a better way to go.

Thanks for the input Burleyboy. When I set the fan in bios as you suggest, it runs at 6700rpm and is loud. Is there something specific I need to set to tell it to calm down?

 

I've been experimenting with various speeds in smart guardian with the following results:

 

in full AUTO (defaults) mode---> 6300-6760 rpm, 41C, loud

in AUTO mode w/15 on fan ---> 5444rpm, 41C, less loud

in AUTO mode w/10 on fan---->5114rpm, 41C, same noise as 15

any setting in AUTO mode less than 10 has same result as 10 setting.

 

in software mode 90 setting--->5114 rpm, 42C, can hear fan noise

in software mode 80 setting--->4327 rpm, 43C, still can hear the fan slightly over system noise

in software mode 71 setting--->3660 rpm, 45C, starting to not notice fan noise

in software mode 63 setting--->2860 rpm, 46C, can't really hear fan over system noise

in software mode 53 setting--->2280 rpm, 46/47C, no change

in software mode 43 setting--->1550 rpm, 49C, ----

 

[To try and gauge the amount of noise from my comp as a whole, I set the fan speed to 0 and listened...that way I could tell what was the chipset fan and the rest of the noise from the case.]

 

So it looks like about 65 or so is a sweet spot for my system. (I'm sitting about 4 feet from the case right now).

Hmm, if you set it to come on full in bios, (let it idle for 5 minutes or so to stabiliize) at say 2 degrees over what your idle temps are, in bios and then reboot back to bios, the fan speed should read about 3000 rpm. At least thats the way all of mine have worked, even using the 6-23-05 bios. If you can get it to do what you want it to do using Smart Guardian software, thats okay I guess, but I'd sill prefer to use the bios settings to achieve the same effect.

BB, I'm going to reboot and try again....brb.

 

Ok, I'm back....In Bios, chipset fan is idleing at 3668rpm and 44C. So I set it to come fully on at 46C. Save and rebooted...as soon as I get into windows the fan kicks in and I can hear it. I made sure both smartguardian and MBM5 were turned off. Still can hear it. Opened smart guardian and chipset is at a nice 40C, but 6000rpm! What am I doing wrong? Why won't it idle nicely at around 3k rpm on it's own?

thanks for the responses guys (and i wasnt aware this was a common issue). i only had this board for maybe a month before it started making noise - my old one, which i had to RMA, never had this issue in the 10 months i had it.

My vote goes for the VC-RE.

1. It sits no higher than the stock fan, thus does not interfere with video cards, etc.

2. It does a better job of cooling the chipset - most report a drop of at least a few degrees C

3. It's pretty quiet

 

BUT it doesn't really twinkle :P
