Yep. MP3 sound quality is definitely not for HiFi enthusiasts. (Then again, if you're a real HiFi nerd then not even wav format does it for you, since few hdds and computer D/A converters can compete with a really good cd-player. So stick to the silent computer nerd thing.) Nope, with an external D...

Have to give some feedback on this. Let me start by agreeing that extreme audiophiles can be every bit as moronic as any other fanatics. Be it fine wines, SUV cars or religion. But discussing something that never really interested you can be tricky. Pardon me for saying that some of the posts here a...

The V series need no cooling. No fan. No worries hanging it inside the case. It rules!

Well, what do you know. I run a Raptor and a Samsung as well. (Raptor 740, Samsung V 160, Barracuda V 120.) As you can see I have HDDs of every speed. The Raptor @ 10.000 need lot of cooling, which adds up on the noise problem. The Barracuda need standard cooling. The Spinpoint V @ 5400 need no cool...

Having used my DDC for a while I must say the noise it makes is rather irritating. Be warned. It takes a lot of heavy dense material isolation to quiet this pump.

Just a note on the DDC pump: It must be isolated because it makes a rather irritating sound. The Eheim is much quieter, but bigger and vibrating instead. Get the DDC wrapped up in something heavy (dense material stops sounds) and you'll be fine.

I've built lots of quiet air cooled systems and own (and constantly fiddle with) a mad-scientist-experiment water cooled machine with twin loops, cooled HDD, automatic fan control and all kind of weird shit like an alu case acting as a heatsink itself. These are my recommendations, might be true or ...

The specs given says it starts at 9V and runs at 8V. Mine starts just fine with 8.

Why not build air ducts from the intake funnel to the parts that need cooling? That way the fans in the internal case will help your Papsts and the problem with hot air in the PSU section could be solved. Get that air to where it's needed! To do this effectively you may have to ditch the internal ca...

I run these two pumps in two separate loops. DDC: 12 Volts. No need for relay, no 230 V in w/c internals. Probably very reliable. (Used in Apple system.) Small. Pumps very good in a restrictive loop. Amazingly smooth almost no vibrations. Rather quiet. Eheim: 230 Volts. (Standard.) Extra PSU load th...

Boring background: I have divided my w/c system so that a 1048 propelles a loop through cpu - rad 1 and another loop through gpu - rad 2. For those in doubt, rest assured splitting the loop is the answer to most choking of the pump problems. The third loop along the alu shell, for passive cooling, i...

Ooops.
I stand corrected.

New scientist article
Cooligy.com

Cathars article is excellent and well worth reading. His conclusions are a bit off for SPCR though, because Procooling serves the o/c crowd mostly. I believe the numbers serves as final proof that all this endless talk about flow rate is just a nerdy waste of time. Unless you're at the overclocking ...

Cheap and effective is to use what cars use: glycol Nothing grows in something that poisonous, it inhibits any corrosion activities and helps make the water less conductive. Dirt cheap too. I use 1 part glycol to 3 parts distilled water plus a miniscule pinch of detergent to counter the remaining su...

Nice post, chylld! Some thoughts: Any heatercore with fins set narrow work best with high cfm fans such as the ones they use on overclocking tests. For silence, use heatercores with less air restriction or it will create a noise even with a 4412 at 5V. (I use 2 x 4412 at about 4V and it still makes ...

Anybody tried Dvorak for swedish (or other non-english language)?

I'm sensing that the headline for this thread attracts overclockers chiefly. I'll take the liberty of changing it from "On overclocking" to "Do you overclock?"

You are absolutely right, Bluefront.
But unfortunately this is not the reason for disliking him.

Noticeable whine (with case closed, about 1 meter away): None, but my case is internally isolated. Otherwise I surely would have heard just a little whining, so I voted "whine" in the poll anyway. Noticeable whine (with ear next to harddrive): Oh yes. Model Number: SV1604N Supplier: Mycom.se Month o...

Some people might need o/c, however in my opinion there are plentiful other sites out there catering to this and the SPCR forums are better off sticking to the silent business, save the "Not silent" thread. Btw, professional mean exactly the same thing in swedish: professionell yrkessmässig, skickli...

Bush actually got 2 non-US votes!? I wouldn't be surprised if he was polled the most disliked person in the entire world.

I started a new thread about this in "the silent front" section.

I want to go and vote!

Isn't it funny that at SPCR we find both overvolterers and undervolterers fiddling with their CPU's to optimize performance? Say what you want about overclocking, but from a silent point of view it's plain folly unless the cooling system is truly state of the art. Correct me if you think I'm wrong, ...

A piece of foam under a 1048 is not enough if a 200 rpm Nexus is the reference, believe me. If you want silence, hang the pump in elastic cords, use soft silicon tubing near the pump, isolate the case internals. You shall then see the light.

I'm not completely sure that you can accurately say that you can't do watercooling more quietly than aircooling. You may say that the quietest rig is one with a thouroughly damped pump and totally passive rads and you would probably be right. But other than that, I think you're right about everythi...

Just remembered I also at the time appreciated the opportunity to be able to move the w/c system to my next generation computer. But that means scrapping the old one or buying new coolers anywway. New coolers for the old computer makes no sense, since you can bet your ass there will be new coolers o...

Well, I agree with you all. Water cooling is better than air cooling for overclocking purposes. The problem is that w/c has a reputation of being the holy grail of silence and people here continue to ask questions like "I wanna w/c for silence, which extreme rad should i hook up on wich industrial g...

My project settled down som 8 months ago and I haven't been around here any much lately. Some perhaps valuable experienses have been made: Having the case act as a heatsink still rocks. Since the Raptor is stuffed into a sound dampened water cooler and the case is internally tapestried with heavy so...

1911user said it. This holds all the more true if you w/c for silence. The choice is big rads or powerful fans. All this talk about flow, northbridge blocks and shit is only for overclockers. Not to mention the ongoing hunt for bigger, louder pumps. Unless it's totally suspended in the case it's bou...
