High Performance with Absolute SILENCE

Guys, thanks for the replies.

But I would like you comment on the setup.

What do you think? Sub-30 dBA @ 1m? Or not?

For the latest version of your list? Nope... I think the GTX285's, at least, would send it over the edge.

I'm confused.

In reviews of the X-Bit Labs, the GTX 285 get the same good accoustic characteristic of the GTX 260.

In dB calculator [ http://www.cesva.com/servi/?lang=prt&pag=dbcalc ], using the nine noise spots (HDD x2, VGA x2, PSU x1, fan x4) in 20 dB each, the result was 29.5 dB (remeber you that the question is about idle system).

I'm sorry for the errors of the language. I only speak portuguese, so, for me, is very hard to express me in english.

Just until someone more knowledgeable in sound characteristics replies, dB and dBa are different things. db is not the same thing as dba. A dba is a measurement to more accurately measure the loudness, db is the log based measurement which isn't what you think. EG 30db is not double the noise of 15db, its many times more.

Personally, I wouldn't buy a gamer oriented headset. A normal high quality headset will do the job of gaming just fine, along with better music and movie capabilities. That is, if you don't need one with a microphone.

The Xonar DX is a good sound card. I wouldn't recommend anything else, so it's fine.

In terms of noise, The other SPCR members have more to say than me. I think it's pretty quiet.

Looking better...

are you planning on suspending that Hard Drive?

lb_felipe · Post by **lb_felipe** » Fri Jul 10, 2009 5:05 am

Thanks for the reply.

In principle, no.

The P183 has a good HDD fixation system and Caviar Blue 640 GB vibrates little.

But I can see doing this in the future.

This last list is MUCH better !
although my personnal experience with enermax isn't great (had a nexus before that was better), it's a good choice.

lb_felipe · Post by **lb_felipe** » Fri Jul 10, 2009 10:09 am

Thank for reply.

I and my wish lists...

I expect ever learning more.

Your personal experience surprised me. SPCR recommends this Enermax. It, together Seasonic M12D, is better SPCR ranked.

What's Nexus you speak? Value 430? It is little output power wattage rated.

frenchie · Post by **frenchie** » Sat Jul 11, 2009 12:03 am

Yes, that's the Nexus I was talking about.
Maybe I just wasn't very lucky with the Enermax, there are lots of people out there who are very happy with them (includong MikeC !). Also bear in mind that if one day the Enermax fan starts being noisy (my case) you can't change it, they have a special fan.
But once again, most people like thos PSUs a lot, so I'd say it is a good choice.

hum, obrigado.

Between Corsair HX620W and Enermax MODU82+ 625W, which is do you recommend and why?

Thank you very much.

Thank you very much.

If I remember right, SPCR liked them both...I would probably buy whichever one I can get on sale at the time of purchase.

lb_felipe · Post by **lb_felipe** » Sat Jul 11, 2009 8:11 am

Thank you for replying to me.

Does Corsair HX620W take advantage of the fact that its fan is easier to be replaced (not a special fan)?

yensteel · Post by **yensteel** » Sun Jul 12, 2009 9:04 pm

The HX 620's fan isn't exactly normal because of it's tiny fan connector. You will either need to do some wiring mods or buy an adaptor.

lb_felipe · Post by **lb_felipe** » Mon Jul 13, 2009 12:20 pm

Thank You!

What is most appropriate for this silent PC, MODU82+ 625W or CP-850?

As an aside, if you're building a gaming PC, your monitor choice (HP LP2475w) is strange.

It's a superb monitor (I have it myself), but it's more of a high end office monitor. Although it'll do fine on games, you can find far cheaper monitors that will perform better for gaming purposes.

lb_felipe · Post by **lb_felipe** » Wed Jul 15, 2009 1:21 pm

Thanks for the advice!

I chose it because the LP2475w has a IPS panel derived, low acoustic noise, HD support, very low input lag and zero ghosting.

Will not only gaming, despite being the principal.

dB(A) is based upon dB, just that it add a frequency filter, resembling the characteristics of the human ear. 30dB can be the same as 30 dB(A) for certain frequencies where the filter is 1. (see http://en.wikipedia.org/wiki/A-weighted)

since the noise of fans is usually low frequence, the dB(A) is much lower than dB for the same system.
