Silverfox Posted July 18, 2007 Posted July 18, 2007 I think he knows what he's doing. Sure, but I just figured that with that much cash at disposal, a dedicated amp would have been a logical choice. I'd also be intrigued to see how/which soundcard is intended for use (assuming that a soundcard solution is intended) edit: after seeing the forum in question, it makes a little more sense now, but this isn't a "conventional" tactic, hence my conventional thought Share this post Link to post Share on other sites More sharing options...

That explains why he's using a speaker amp. Share this post Link to post Share on other sites More sharing options...

LivingGhost Posted July 18, 2007 Posted July 18, 2007 (edited) I do my research. It'd be interesting if there were a headphone amp that could power them, they need about 7watts, I think. And it appears as if Nexus fans ARE rebranded Yate Loon fans, or at least the 120mm Nexus is a YL D12SL-12. Edit: That Corsair PSU is a rebranded Seasonic with modular cabling, so it looks like that is my new PSU.

Silverfox Posted July 19, 2007 Posted July 19, 2007 Edit: That Corsair PSU is a rebranded Seasonic with modular cabling, so it looks like that is my new PSU. Correct. I have one (as well as a Hiper 580w Type R), so I can vouch for it being almost silent. If you are looking to get almost totally silent...you'll need to think about a quieter hard disk too - the Samsung Spinpoint is excellent!

Bleeble Posted July 20, 2007 Posted July 20, 2007 http://www.silentpcreview.com/article8-page2.html Nifty. Now I know what to do when my hard drive cage fills up. One thing I was wondering, though, is what temperatures did he get with sandwiching and suspending? He didn't provide any numbers.

Guest ecthlipsis Posted July 20, 2007 Posted July 20, 2007 I didn't read the other posts, as I'm really tired, but even if they mentioned this I will 2nd it. Get Nexus fans. Their website is www.stopthenoise.com, if that's any indicator. By far the quietest fans on the market. I use only Nexus in my PC's =D Share this post Link to post Share on other sites More sharing options...
Silverfox Posted July 20, 2007 Posted July 20, 2007 Re: hard drive suspension. You'll still hear a whine/read noise on many drives, no matter how well mounted they are Plus, that guide is hella old in terms of the drives used - 30GB and 40GB?!

Silverfox Posted July 20, 2007 Posted July 20, 2007 It's still used a lot. Indeed it is, but 20/30/40GB drives are not You might find no need for it with newer and quieter drives. It'd be a pain for me (not necessarily you though) because you'd not be able to move the PC much without drives slipping about Share this post Link to post Share on other sites More sharing options...
markiemrboo Posted July 20, 2007 Posted July 20, 2007 (edited) I do my research. It'd be interesting if there were a headphone amp that could power them, they need about 7watts, I think. They actually don't need 7 watts. The maximum power handling of the headphones are 1W. The confusion is coming from the fact that a loudspeaker amp is typically designed to drive 4/8 ohm loads, whereas the headphones in question are 120 ohms "nominal". A higher impedance load would mean more voltage swing and less current draw. Lower impedance would mean less voltage swing (relatively speaking) but more current draw. A loudspeaker amp rated at 1W in to 8 ohms would simply not have enough voltage swing available to drive the headphones to anywhere near max volume, and so would start clipping. Very simplistic example: 1W @ 8 ohms = +/-2.83v and 0.35355A / 353mA 1W @ 120 ohms = +/-10.95v and 0.09129A / 91mA So you need about a 10W @ 8 ohm loudspeaker amp to drive them to about 100dB simply because: 10W @ 8 ohms = +/-8.94427v A 10W amp will be able to swing +/-8.9v in to a 120 ohm load without clipping. It will not ever actually be using 10W, but still <1W. Unless I am missing something it shouldn't be difficult to design a headphone amp, or find a headphone amp, which can swing +/-10v and be able to supply ~100mA of current (plus a bit more for headroom perhaps). edit: it's actually surprisingly hard to find a headphone amp that'll give 1W in to 120R Guess it's because 99.99% of headphones need like... 10-100mW or something to reach the same sort of level, so there isn't really much of a market for it Edited July 21, 2007 by markiemrboo Share this post Link to post Share on other sites More sharing options...
