Hello miker: A really cheap and easy way to quiet these stamped metal grills and also get more air flow is to simply bend the arc sections with a pair of needle nose pliers out to 90 degrees away from the back of the PS case. This presents only the thickness of the metal to the air flow and it reduc...

Hello: I read this test a while ago; well before I had come upon this site. And at the time I found it frustrating partly because it sets out to be a "scientific" test, and then in the end, it is so vague and inconclusive. I'm glad for the description of the method -- I'd bet a dime against a $1 tha...

Hey BTG: Here's what you get with the Google translator; Engishish: http://translate.google.com/translate?u=http%3A%2F%2Fwww.noiseless-cooler.de%2F&langpair=de%7Cen&hl=en&ie=UTF-8&oe=UTF-8&prev=%2Flanguage_tools This one will work, as well: http://tinyurl.com/403x You can click on the TOC on the lef...

Hello:

If there is barely room for the fan -- where will the air come from? I hope that you have a hole with a grill for it...otherwise it'll get noisier and not blow a whole lot.

To expand this thread a bit, here are all the 120mm/12cm fans that are for sale on NewEgg.com in alphabetical order: Enermax Adjustable 1500-2300RPM user adjustable $13 + $6 shipping. The fan is clear (woo woo!) and it comes with a wire grill (it's gold color!!) and it has a screw-type potentiometer...

How many folks out there have some nice quiet systems, and also run distributed computing programs? (SETI@Home, Folding@Home, Prime95 ?, etc) Pondering how well quiet cooling works with continuous 24/7 100% CPU load. Right off the bat, let me qualify my response by saying my machine is not quiet. I...

Whats the cfm/db spec on these fans? I did some digging on the link that Ralf posted, and here's what I got: 119mm SQUARE x 25mm (4.69" SQ. x 1.00") LOW-NOISE BOXER™ FANS PLASTIC IMPELLER AND VENTURI Type Connections Bearings VDC Watts rpm cfm dBA Stock No. 4710NL- 04W- B10D00 Lead Wire Ball 12 1.4...

Hello Gandalf:

This article at Dan's Data is a pretty thorough look at this subject:

http://www.dansdata.com/power2.htm

I'm glad you have started the recommended fans -- it may not be all scientific and such, but with some feedback and cross referencing of our experiences will very likely be quite accurate and reliable! What it may lack in objective measurements (for now), I think it can make up for with breadth. Thi...

Hello randyharris: There are three case with some isolation, that I am aware of: one tested right here in pages: http://tinyurl.com/3so3 is the Antec Sonata which is promised early in January. Another Antec case, similar to the Sonata, with (much?) more restrictive fan grills but you can Dremel your...

Hello:

Here is a brand of fan -- Silencer, that I have not seen mentioned in these pages:

http://www.pcpowerandcooling.com/produc ... /index.htm

I'm not sure why the 92mm version only has an additional 1CFM , but with an increase of 3dB, but the 80mm is pretty good.

Hi Ralf: I also use Opera 6.01 and Zone Alarm Pro, so I guess that I have not shut off the warnings about 3rd party cookies, or something. They are getting excluded -- it's just that I don't get these warnings from any other page on this whole site -- just this one. I wanted to point any conflict of...

Hello: This is off topic, but does anybody else's firewall kick out warning for about 5-6 cookies when they come to this page? If I had to guess, since Rod also sells Pabst fans, he might be trying to see who comes to see his system -- because when I go to his web site, I also get these cookies! :ev...

Hello: Given that most Thermalright heatsinks are rectangular as far as the top where the fan attaches, and how an 80mm fan overhangs them, I would have to guess that a fan blowing up would not not work well. However, with one of those 60mm to 80mm adaptors, they might work better this way. Can anyb...

Hello: From a post from "Copenhagen" over on the Storage Review forums: ============== The reason for this is that the rest of my system is rather quiet (around 17 dBA adding the noise produced by all moving parts excluding any form of drives). I only have 3 fans in my PC and all are of the very sil...

Hello: If you plug a "real" ATX power supply into a Dell motherboard, you will cook the motherboard! UNLESS you use something like this: http://www.endpcnoise.com/cgi-bin/e/dellconverter.html?id=kjk3Rvz2 I have not used these folks before, but I happened to see this Dell adaptor when I first visited...

The only thing that can work along these lines is a headphone type setup (and the Bose units used to cost a lot less, BTW -- like $70-80 IIRC). Because in order the cancel a noise, the "antidote" MUST be exactly 180 degrees out of phase, and since the sources of the various noises in a computer case...

Hello skidoodle: If you're saying that a 1/2 sheet of 3/4" plywood only costs $4, then you need to tell us the name of your lumber yard! Last I checked a full sheet (4'x8') of 3/4" AC plywood was around $40, so half that plus the charge to cut it in half might be $25-30. If you want a nice veneer (s...

Hello jojo4u: So, the IBM 180GXP 60GB is the quietest at idle and seek with AAM. (BTW, what does AAM mean specifically? I'm assuming it's the quiet mode.) And it beats the 'Cuda IV (the next quietest) in transfer speed by 42MB/s vs 35MB/s. The 'Cuda IV is quieter in the "fast" mode, though it is slo...

Hello:

Where can we see what these adapters look like?

From looking at it, I would not be so sure that this one will work very well. The thinness of the two vertical elements wouldn't seem to be able to carry much heat up to the fins. Also, they appear to be set one over the other and how are they fastened to the base? Soldered? Welded? I'd want to see ...

One thing that I learned by reading some of the articles on Storage Review is that while somewhat elevated temps don't kill a HD right away -- they greatly shorten their life! So, even if you don't hit 60d (where ever you were measuring it) higher than "normal" temps will do in hard drives, sooner o...

Hi quokked: Having no grill at all is fine for some places, like behind a front panel, but if the fan is exposed to the room, then I'm sorry -- there has got to be a grill of some sort! You know, I've got two kids -- each with ten fingers! ;-) Actually when bending, you need to be careful/creative t...

Hello Ralf: Did you put something over the edge of the cut round hole? It looks like some sort of rubber/plastic edge protection. If so, it to reduce noise, or "just" to cover a sharp edge? I'm glad you mentione this case: I have been eyeing it on New Egg, and those grills were my only reservation. ...

It seems to me, that one category missing from both the Recommended section and from the forums, is Quiet Cases. While I'm posting, here's a Cheap Trick for quieting those stamped metal grills that are all too pervasive: take a pair of needlenose pliers and bent the arcs outward away from the fan. I...

Okay, Alpha recommends that you mount the fan to pull air through the PAL8045. Dan's Data (dansdata.com) says that this gains you about 5% better cooling. It seems to me that better cooling can be quieter... Why is it better to pull the air through a heat sink? Several reasons, I think: 1. The cool ...
