Okay! This is driving me nuts! Really want to sort this stupid thing out

[AdladUK]

Hello,

I posted a thread a couple of weeks back about my CPU cooler (Arctic Cooling Freezer64 Pro) making a really annoying noise when idle. It's sorta like the noise a hard drive makes when it's in use.

The thread for reference is http://forums.overclockers.co.uk/showthread.php?p=10432890

Having tried everything I could think of I decided to order a new cooler. I picked the Arctic Cooling Alpine 64. Mainly because it was a nice cheap replacement (only about £6).

Having installed the cooler with no problems whatsoever I am now totally ****** off to find the same annoying sound is back. I know 100% it's the CPU cooler as well. Because when I unplug the CPU power cable (for a couple of seconds) the noise disappears.

Please help Overclockers

Motherboard is an Asus M2N-E SLI

CPU is an AMD X2 4000+

Both without any overclocking

Stupid answer, but is there maybe a wire touching the fan and its rubbing making the noise?

No, absolutely nothing is in the way of the fan. I have made sure of that

2 different fans. Both making the same stupid noise. Both under the same circumstances.

I think maybe it's some voltage setting on the motherboard in the BIOS? But I wouldn't know what to change. And I just reset the motherboard BIOS to default, and the noise is still here

Sounds like one of the finns could be bent and is vibrating when the fann spinns up , tale of the cooler and have a look at the finns . It may be that you just have to bend one of the finns back .

m8 this is a new cooler. The old cooler was doing exactly the same thing. What are the chances of that?

And when I installed this one it seemed perfectly fine (build quality wise)

Sorry fella only thing that comes to mind the way you describe the noise . If its the second cooler that is doing then either the cooler is fubar , my above solution , a wire is causing it or its not seating properly .

That's the point though, both coolers are making exactly the same noise. So I really don't think it's the cooler.

My best guess is some sort of voltage setting on the motherboard, but I wouldn't know where to start with that.

As I mentioned in the old thread the noise is only made when the computer is idle. When I play a game it goes away.

Surely it should be the other way around?

what setting have you got it on in the bios

Hello,

Vcore Voltage = 1.29V
3.3v Voltage = 3.31V
5v Voltage = 5V
12v Voltage = 11.96V

CPU Temperature = 26C
M/B Temperature = 31C
CPU Fan Speed = 2070RPM

Get your head in there and have a good listen to find out exactly where on the cooler this noise is coming from.

Can you wobble the cooler?

Anything else wobbable that may be affected by the cooler?

As said, ensure all the wiring is clear and non-wobbable?

Check for general wobbliness?

Sorry, I have an affinity for the word wobble at the minute.

Good luck and hope you get it sorted.

Wooble wooble wooble.

I can't specify where on the cooler the sound is coming from. But it's definitely the cooler.

Yes I've tried "woobling" it around, and it has 0 effect

Thanks anyway

sounds like an unbalanced fan. getting the same thing on two different coolers is unlikely, unless artic cooling are using shoddy fans which, for £6, isnt impossible is it.

I really don't see how it could be unbalanced. I fitted both very carefully, and they both went on very well.

The replacement fan was £6 (the one I have in now), not the original. The original was an Arctic Cooling Freezer64 Pro, and that was like £15

Some fans do not like PWM Control and make a funny noise. (aint sure on set up of your mobo but used Asus and them coolers for customers.

By this do you mean the "optimal" "silent" "performance" setting option in the BIOS?

If so, I don't think it's that. I've tried every setting (even turned it off), and the result seems the same every time
