Whats the next step from here?

Post by kattisavan » Tue Sep 07, 2004 1:00 pm

I have switched every fan in my case, changed to zalman passive NB and VGA.

I removed my fan-grills.

Modded my PSU with a duct.

Removed my loud disks.

Only have a seagate 7200.7 now, with rubber at the screws.

I thought i would be satisfied then, but i can still hear my computer 4-5 meters away. =(

I cant figure out whats the loudest thing now. I gather its the sound from 3 Adda fans running at orginal Volts.

What to do?

Buy fanmate, or install acoustic damping... or something else?

What do you suggest.

Did you remove the fan grills?

ADDA fans are known to be quite good, but particularly undervolted. While your suggestion of FanMates would be good, the cost of three FanMates may already add up to the cost of a decent 4-channel fan controller that you could mount into a bay. With some intuitive cable management, front mounted fan controllers are much handier than the FanMates because you can let them run very slow/quiet when just idling or doing some simple task like WWW/IM/e-mail, but then when it's time to turn the heat up, like gaming or some other intensive task, just a twist of the knob will elevate fan speeds that little bit to provide the additional cooling you'll likely need. FanMates, being mounted in the interior, are not as convenient, and in some cases, not as quiet, since it means you'd have to leave the fans the a minimal speed that's safe during heavy load, so the times the machine isn't loaded, you're dealing with extra noise.

Actually, if you could please provide some more system specifications, we'd be better suited to ascertain what solutions would be optimal for you.

I will, however, admit that you've already taken quite a few very good measures (swapping out for passive components and ducting the PSU were definitely smart!), so you've got a good start already and it only needs a little more work. I'm assuming, of course, that you're not running something like a 9800XT and a Prescott 3.4! :P

Try a fan controller. Cheap, easy, simple.

Thanx Edward, that seems like a good idea.

My system specs are in my signature.
Radeon 9600pro - not varm at all :)
my two 120mm Adda - Is running at 1000 rpm, and i used fan speed 4.0, and found out that they are more silent when at 800 rpm.

And my PSU - Antec Smartpower 350W with a 80mm Adda, was much more noisy than my 120mm Adda.
It ran at 1850 rpm, i changed it too 1000 rpm and it was dead silent.
So it seems like a good idea for a Fancontroller :)

My case is not vibrating much cause i only have one seagate hd, mounted with rubber at the screws. When the harddrive is working hard i hear it easily. At idle its almost silent.

The CPU - Artic Cooling TC
Its running very slow, only 530-630 rpm in windows :)
And 1500- 1800 at load. So I consider it not to be a source of sound.

I think Ill buy a fancontroller then, but which one is good? But isnt Adda already undervolted to much for the fancontroller to do a good job? And can I still controll my Arctic Cooling, which is temp controlled?

And what shall i do with the hd?

I can think of three options for the hard disk, in increasing order of expence...
1. Put it in an enclosure such as those made by silentmaxx
2. Replace it with a good old spinpoint P
3. Replace it with a laptop HD like the spingpoint M
Or combine 1 with 2 or 3 for even more quietness!

If you are able to control every fan through software like fanspeed, then there isn't that much point in getting a fan controller. Plus, if you find the system still to be noisy even when you have them turned down as low as you can with fanspeed, then getting a fan controller will not help at all. In fact, your system could even become even louder. Many controllers will not go below 5V, while software can be set as low of 0V.

Mine does. Goes to 0V. Vantec Nexus NXP-300 series.

I didn't see the part about how he has it on software control.

You shouldn't need to replace the 7200.7 HD. Have you read the sticky in the storage section? Suspension makes a huge difference to every aspect of HD noise, both with "quiet" and noisy drives. It is cheap and easy to do.

If he can use fanspeed to control all his fans, then using a fan speed controller (even one that goes to 0V) will not help with noise.

Yeah I had not realized he was already doing that, since he originally said...

Problem is, I don't yet have any other suggestions.

I only used speedfan to check if noise would go down, I lowered the rpm, and it worked on all my fans.

Speedfan can only silence NB and CPU fans, so I can only use Speedfan on 1 FAN at a time, cause the CPU is connected, and the NB is a passive fan.

So if there is another program that can silence all fans then my problem could be solved, but i dont think there is.

So I will be buying a Rheobus which can change fans from 12V to 0V.

Isnt it the smartest thing to do?

I still have theese questions though: Isnt Adda already undervolted to much for the fancontroller to do a good job? And can I still controll my Arctic Cooling, which is temp controlled, with the controller?
