<i>Okay how would I put pax mate on my cpu fan? Will this stuff melt if I put it along the sides of the fan between the heatsink and fan?</i>
I would hold off on using it with the CPU fan until last as you bring up a good point. I myself wouldn't think it would melt but I will run some tests and let you know. You can also e-mail Akasa at
http://www.akasa.com.tw and ask them what the behavior of the foam is like under high heat. I'm really sorry to be bringing this up so late but within the first 1-2 weeks you will have a smell from the Pax Mate. Most people get used to it, but again, I'm sorry I forgot to mention this earlier. I believe it's sound reducing properties way outweigh this smelly period though. The smell is kind of like what closed-cell foam smells like if you've ever smelled it. <i>Edit: It actually smells very strongly but only up close. I can't smell anything wafting through the air. But if you are using huge strips then you probably will. Melting also shouldn't be an issue with these.</i>
<i>Hmm okay lets say I add the Panaflo fan.. Would that take up two 5.25" bays? If you head over to
http://www.noisecontrol.de/info/infmenu_3.htm you can see a few pictures with the fan mounted on but not sure if it will take up two slots... not even sure how the fan is mounted on the no vibes..</i>
I just read the site. Looks like you have to buy a special version of it which comes with both the fan and mount, and in the U.S. they only carry the regular version (takes up 1 drive bay by the way). Do you have a thermometer somewhere? Over the next couple of days try measuring the ambient temperature try to get a good idea of how hot your drive will be. Remember that to determine this, just add 20 C to the ambient temperature and see if it's higher than 55 C. As long as where you live is below 35 C on hot days you can get away with no cooling at all. Also the No Vibes III actually seems to expose the drive to more air on the sides than a 3.5" enclosure will, so it should be a tiny bit cooler from that too.
<i>Well if you say the more fans the more sound pressure builds up? So then would it be better off leaving the case panels off? Then the sound pressure can expand out in open air instead of being inside a case?</i>
Actually it's not like that. Having the case on will actually reduce sound pressure going into the air because it has to pass through the case before it can pass to the air (remember sound is essentially vibrations, and anything can absorb vibrations). So obviously taking the covers off the side will increase noise. I've been suggesting Pax Mate the whole time because it adds yet another layer that the sound must pass through before it can reach your ears. By the time the vibrations that cause sound are done passing through 1) the Pax Mate attached to your fans, 2) the aluminum in your case, and 3) the Pax Mate attached to the case, it will have dissipated a lot. Actually, if you had 6 feet of dense aluminum surrounding the fans, you might not hear the sound at all. It doesn't matter what it is, having objects between you and the source of the sound obstructs and reduces sound. Like I said, the cellular foam helps capture the sound that usually causes the case to vibrate, thereby reducing overall sound.
<i>Yeah there's a noise difference with the hardrives off and on... I hear a high pitch coming from the drives since it's spinning so fast..</i>
Thought so!
Most of that sound will disappear. People have no idea how quiet 48 db actually is when it's measured in hard drives, a) because the sound is mostly contained within the chamber of the hard drive, and b) because most users simply have it screwed very tight to their case so it rattles the case like crazy.
<i>The pax mate will help with noise but it can also help contribute to heat...</i>
This was something I heard before. Akasa actually says that it will increase case temperature by 1 C. But if you read some of the reviews, some have reported 1 C increases (but never above 1 C) and some have reported no temperature increase at all--there probably is some, but it's not a real threat. There's a <A HREF="http://www.overclockercafe.com/Reviews/Akasa_Sound_Mat/index.html" target="_new">review here</A>. Unfortunately I couldn't find a better review because viper lair's review disappeared recently. I have an aluminum case, and I've noticed no huge temperature increases by using vibration absorbing foam.
<i>Well not you got me thinking because watercooling will need maintenance while fans don't except a quick vaccuum job...</i>
