Fans too loud...

Schpasm · 07-04-2009, 12:52 AM

first of all thanks everyone, i got my computer all fixed. Brand new computer desk, brand new 24" inch lcd, beautiful lighted case, and bazooka 2000w speakers..

amazing... and also super comfy chair lol.

Thanks all!

Question:

My fan (120mm) is way to loud in the case. My brother is sleeping and he is complaining. Now i heard there are fan controller (hardwares), but is it possible to use another solution until i order one?

i heard something about speedfan, but that only monitors the temperatures...

If that fan is not plugged into your motherboard, the only other solution would be to buy a fan controller (they cost around $20).

Speedfan can change the fan speeds for fans plugged into your motherboard.

It is plugged into system fan 1, i tried changing the speed but it didnt work. I dont if its through configure or you have to do it from teh "100%" part.

Anyways, i removed it and I put an old fan 80mm, and my temperature went down 3C-4C lol. Its also more quiet

If you have a 3 pin to 4 pin adapter, you can do the usual 5v,7v mod to reduce the fan speed.

Schpasm, most fans that come with cases are complete crap. You should get a cooler master r4 series fan. They are 19dba.
I know the fans on my Raidmax case are the worst I've ever seen and I only just ordered two of those fans myself to replace them both.
The non-LED fan on the back of my case is pathetic - I can hear it yet still can not feel the air behind it!

19.9dBa is what the CM R4 fans are rated for at 1200RPM, they go up to 29.9 at max which is 1800. I can't wait until mine get here and I suggest you simply replace them first, many fan controllers are unreliable, the design has never been perfected.

Replace your fan with one of THESE, they are literally the quietest fans made. They are pricey, but 78 cfm of air for only 14dBA.

If you want to add a fan with out having to worry about any type of controller the go for the "THERMISTOR" style fan. One of THESE is rated between 6-14 dBA, with a cfm rating of 24-72.

I have yet to come across any fan that has the same performance and to noise ratio as these fans....call me a fan boy...idc

I've heard that the silenX fans were crap, but the person could have been biased.

Your board might have an automatic fan control (some of the Asus ones have it and the gigabyte has it for at least the CPU fan)

You could as Burton said do the 5 V mod or you can go for a PWM fan like the arctic cooling ones; they let you daisy chain multiple fans together. You can also go for a fan controller (some are digital, some are manual). so you really have a lot of options that you can go. It just depends on how much you want to spend.

Silenx had a major bad rep at SilentPCReview mostly for their less than honorable promotion methodology. Basically posting on their forums as their customers to promote their products and bash others. Since then, they have been placed in the same category as Monster Cable, Bose and other products that spend more on advertising than on quality of product.

The above is just one of many such threads on SPCR. With this said, it seems Silenx is trying to live down this past history and they may be trying to make better products now. Not sure but even SPCR is starting to become less negative towards the company.

Still, I think I will stick to other brands like Scythe, Coolermaster, Yate Loon and or Nexus. JMO though.

I only recommended the fan because I have 4 of them, and well they are quiet and do exactly what they are supposed to do.

To each their own though...in the end it is your money

Zenshi · 07-05-2009, 07:36 PM

To be honest, if they are quiet and push decent air, who cares what the reputation is. Maybe I should start looking at them closer. Thanks for the info Cyclonite.

Just thought I would share this, I read this online somewhere a while ago and decided to try it. My case had a ¼” grate over the fans and I cut the grates out to make an open whole, my case got about 7 degrees cooler and with 6 fans it got noticeably quieter. It makes a slight hum like an older TV does when it’s on.

I haven't ever done this myself, but I've read about it on other sites. You just need to downstep the power you are providing the fan. It will run slower, but at 120mm, they are likely already moving in far more air than the system strictly needs.

All you need to do is remove the 5v pin from the connector, and I remember reading somewhere that you need to swap it with the ground line (the wire closest to the yellow 12v wire). Someone more experienced in electrical engineering should be able to explain to you why this step needs to be done.

Anyway, the end result is that your fan runs at 7v instead of 12v. Now you could do that trick with the 12v line instead, and end up with a 5v fan, but I doubt that would be enough juice for the fan to start - maybe to run at, but definitely not start.

I'm pretty sure you connect the ground pin to the +5 V and you leave everything else.

The voltage is a differential and so +5 V is the new ground (or 0 V) so the difference is 7 V. Your fan ran at 12 V because the difference between the +12 V rail and ground had a 12 V difference.

This ^^

It's coming back to me, just very slowly :).

If someone does that to 5 or 6 fans, is it possible their power supply may become less stable?

**Duke3d87** · 07-10-2009, 07:10 AM

if your powersupply has stability problems with 5-6 fans (that's like 15-20ish watts?) you have some serious problems. Generally, i would say no.
