    Fighting the pc noise
    By leoku January 15, 2001, 02:32 AM

    Now I have had Windows 2000 installed, running happily with 128MB and all the action, strategy games, doing unfinished office works at home,etc.. Everything looks so nice and shiny... Except the noise. Steven Jobs hates cooling fans since their noise makes him nervous. My office computer is an old Dell and the overall noise level is way lower than mine. What is the secret here ? Is there any whiper quiet power supply, cooling fans, etc. that can reduce the noise level ? How do I measure the noise level of my pc ? and what is the definition of "whisper quiet" ? I want to fight the pc noise, and can anyone suggest ideas ?

    Get bigger speakers and play the mp3's louder!

    Either that, or line the inside of your case with that sound deadening material that you can get at Car audio shops or Best buy...I hear it works fairly well...

    By Triton January 15, 2001, 03:58 PM

    Is there a noticeable different in the noise that the power unit on the backside of the computer does? And can you change it?

    Mine sounds like a blizzard!

    By DJ Machine January 15, 2001, 05:07 PM

    Ducting always works...which is taking bendable plastic tubing the same diameter as the fan, attaching the tube to where the fan is..and having the tube end somewhere farther away from you.. so the air comes from the other end of the tube, not right where the fan is.

    By ua549 January 15, 2001, 05:25 PM

    I'd replace any sleeve bearing fans with ball bearing fans before messing with ducts and accoustical materials. Also, a larger diameter fan blade running at a lower rpm can move just as much air as a smaller diameter blade running at a higher rpm. It can be difficult to get the CFM air flow specs from a PC parts vendor. I usually deal with an electronic parts shop because they are used to dealing with parts specifications.

    By tu2thepoo January 15, 2001, 06:03 PM

    don't sleeve bearing fans make less noise than comparable ball-bearing fans though?

    By RLX7 January 15, 2001, 08:54 PM

    No, ballbearing are quieter and better(last longer)!

    By tu2thepoo January 15, 2001, 09:10 PM

    i know ball-bearing fans last longer, but i read that sleeve bearing designs typically emit less noise than ball-bearing ones. it might've been outdated information, though, it's been a while since i've read up on it.

    I did an extensive research on the internet today about the quiet fans. I ran into a company called quietpc.com (a Finnish company), their cpu cooling fan and power supply boasts "near silent" quietness. I ordered the cpu fan (called Radial Fin Cooler), but hold off the power supply since I am not sure its spec is for US/Canada. But there are lots of people in the US who ordered the power supply.
    I believe there must be something we can do to create a silent pc but current information simply point to a different direction (noisy ones).
    I will report the the result as soon as I received the fan.
    By the way, has anyone heard of the Agilent's ArctiCooler ? Has anyone used one ?

    By tu2thepoo January 15, 2001, 09:45 PM

    sunon's supposed to make 80-90mm case fans that are the most quiet around. never tried em, but that's what everyone says on this forum

    By IL96 January 16, 2001, 09:16 AM

    This has been discussed before on this forum. You can use search feature to find the discussion.
    As far as I remember the best itdea to cancell out the noise was to put a microphone inside the computer and a speaker outside. So that the speaker outpputs 180o (degree) shifted sound. Just like noise cancelling headphones do.
    Putting quiet fans may be expensive, and might not help. Because harddrive and cd-roms make a lot more noise. For ex. when my 50x cd-rom spins up the cd, it sounds like the computer is about to take off. :-)

    By ua549 January 16, 2001, 11:15 AM

    Interesting. I have a Pioneer DVD-115 and an IBM CD. Both are so quiet I can't hear them when running continuously, only a slight whirrr during start up. My power supply fan was very noisy. It was easy to replace with ball bearing fan for less than $15.

    The PS 250w & 300w units available from SilentPC are for 230 volt input power only. The 230w unit will work on 110 volt mains.

    The noise level is less than 26dB.

    I received an e-mail from quietpc.com stating that I will need 300W power supply, which is currently not compatible with North America region due to the recent modification by QTechnology. quietpc.com is trying to get it back to its original spec but it won't happen soon, so I am out of luck. Other then this quietpc.com, where can I find the quieter power supply ? PC Power and Cooling power supply is not as quiet as advertised, is there any other company making quiet power supply ?

    How do you do it ?

    By ua549 January 16, 2001, 05:25 PM

    I did not do anything special. The drives have always been quiet. My case sits inside a large armoire designed for computers (390 lbs. of fine cabinetry) that helps keep things quiet.

    For the power supply I removed it from the case, opened it up and replaced the fan with a quiet ball bearing model. It was a very simple procedure.

    Thanks for the tip. I looked at their website and the product was quit interesting. Kind of pricey though.

    How do I know if the fan is of the ball-bearing or other type ? Is there a fan specifically for power supply ?


    By *-SiNcErE-* January 17, 2001, 06:14 PM

    I would suggest these following products:

    1) enermax powersupply, these guys have heat sensors to keep rpms at minimal when the case isn't hot. and they have see-thru ball bearing fans which are very quiet.

    2) sunon case fans, I've got 3 of them and the only sound they emit is the sound of the wind.

    By LethalWolfe January 17, 2001, 08:13 PM

    I just built my first comp 2 weeks ago and I like hearing the fans. They say, "You wonderful, handsome, intelligent man you! You built a computer! You are a god!" but mostly they just go, "wwwhhhiiiirrrrrrrrrrr...."

    Anyway,
    I know that doesn't help make your machine any quieter, but maybe if you looked at the fan "whir" a different way it wouldn't bug you as much.

    Sincere where can i get these parts and how much would they cost. My computer is loud as hell and i want it quieter.

    By lil_mary January 17, 2001, 09:13 PM

    Well, I covered the power supply fan's output on the back of my computer with a thick notepad. It quietened the noise by about 75%. But it started to smell funny after a while....

    hehe

    By TechChic January 17, 2001, 09:26 PM

    Hmmm, get one of your speakers get a mic and then take the mic record the sound. flip the signal 180, then replay it and have it do it for like 10 seconds and make it so it loops. And you kill the noise

    the enermax 330watt would be around $40
    the sunon fans are under $10 depending on which model (cfm) you want.

    they're pretty common in any overclocking website and not too hard to find if you do a search. and if you live in Toronto, I could get you some no problem.

    Has anyone here actually done this? I've heard this twice now in this thread. I know it's theoretically possible but has anyone here actually done it?

    By Pakman117 January 18, 2001, 12:08 AM

    Yea, that would be really sweet. How much does one of these microphones/speaker thingies cost? Dang, I'd love to get rid of this humming.

    By CajnDave January 18, 2001, 12:52 AM

    Like SiNcErE said the Enermax is very quiet. I just installed a 430W Enermax Whisper power supply. It has an intake and exhaust fan in it and both are ball bearing fans. I can tell you it is as quiet as my old 250W with one sleave bearing fan.

    By 256K January 20, 2001, 12:30 AM

    This may sound funny but true. I have an Athlon Slot A system. I started to hear a whistling coming from the system, very faint but loud enough to get on your nerves. SO tonite I opened up the case and ran the system, I remembered a post on Anandtech awhile back. One person had the same problem narrowed it down to air flowing in between one vent on the heatsink. Sure enough, my problem was the same. I put a small piece of plastic there, not large enought to cause heat or eliminate ventilation and the noise is gone!!!!!!!!!!!!!!!

    I received the Radial Fin CPU cooler last Saturday and installed it immediately. The overall noise was knocked down quite a bit and if disable this new cooler fan and reboot the computer, the noise level does not change. So it is the power supply and the front case fan that cause the noise. The cooling is outstanding, cpu constantly remains between 34C to 37C even after hours of 3D gaming. I tried to stick my ear to the cpu cooler, but barely hear anything. This is NOT QUIET, IT IS SILENT.
    The company said the voltage-switchable(for North America), ultra quiet power supply should be available around mid February. I am waiting.

    Frankly, Where can I find the information for Enermax Whisper power suppy ?

    Where can i buy the sunon case fans, i also have a fairly loud case. Also, where can i find psu fans?

    By leoku January 26, 2001, 12:15 PM

    I did another research last night and was totally blew away by how many silent coolers out there but no one knows about it. ArctiCooler from Agilent, Molex Radial Fin, LAC Augmented Fan Heat Sink,or Thermaltake Orb among a few. The review I found so far all point to the better performance with silence of these coolers.

    On my quest to silent pc, I am so disburbed by the fact that most of cpu cooler in the market are directing users to noisier configuration by exaggerating the effect. Global Win, Alpha are the culprit and can provide far better performance than those technologically advanced solution at the same price.

    I have installed Molex cooler and I love it. I am in search of silent power supply, probably from Enermax or Q technology, but not PC Power & Cooling's. Getting a silent pc will make music sweeter, clearer and, since I am running Windows 2000, keep my computer 24/7. I do not want to play games on an aircraft engine.

    Oooops. I made a mistake there, here is the correction.

    Global Win and Alpha are the culprit and can't provide far better performance that those technologically advanced solution at the same price.

    Once again. I am on a constant quest for silent pc.
