Project: PrometheusCU - Update #1 - Dec 3rd 08

[S_G]

Wow, that's a pretty good deal for $135. Never heard of the Zen Head, but I've heard great things about Decware in general. Let me know how it turns out for you.

Oh, and what headphones will you be pairing that up with?

[matsta31]

+1 on head phones !

It'll run my HP-1000's, RS-1's, and (soon) K-701's. Head-Fi has the ZenHead ranked at the 7th best amp in the world - so for $135 you really can't go wrong. It's also said that the corssfeed filter is unequaled - I'm a man who loves his soundstage so that was important.


I got my package from Sidewindercomputers.com. I HIGHLY recommend this eTailer - I made this order at about 10pm on a Sunday evening. Gary, the owner, personally responded via email and thanked me. I then amended the order at about 1am, and again Gary immediately responded with the revised quote. Thanks Gary!

I got my Uber Fans!

The AFB1212GHE Revision C Grand High Speed is our newest king of 120mm fans. This dc fan motor provides over 240 cubic feet of air out of a traditional design that has been highly refined and tuned by Delta's fan motor team. Comparisons with our other high end Delta parts show it has modest power requirements for its ability to move so much air out of the standard 120x38 millimeter form factor. It does lack the directional blades which we've all come to know as Delta's patented design, which helps airflow move more consistently straight out of the fan housing. However, as noted in its lower decibel rating, it will also lack the high pitched whine that accompanies directional fin fans. The AFB parts can be undervolted slightly more, but apparently cannot be overvolted as much. For power users adjusting the voltages on these parts, it will be a welcome change.

All 6 fans actually hover.
6 in a row run at 19-21dB at min and 67-71dB on MAX (~1 away).
Even at min setting the row throws over 85CFM at any point (~5cm away).
They have a power spike of ~40W and pull 29.4W at 12V
Which means I need to have 270W of power overhead just to turn on my fans, and another 180W to keep 'em running.

The fan controller - the build quality is nothing to write home about but I'll straighten out the components, clean off the acetone, add new heatsinks, and make a new frame.
I went with this controller because it's the only controller -that I could find- that can offer up-to 45Watts per channel.
Most 120mm case fans will draw no-more than about 2-3W - so a low wattage controller will more than do you.
The Delta Fans I'm using however draw 29.4W w/ an on spike as high at 40W so they need more beef!




Also some arctic silver TIM and TIM remover - some of which will be used in this project... most will go elsewhere.


Lastly a free gift from Gary - this little treat which I rather enjoyed because I happen to love little metal machinist rulers. =)

Oh, god, those fans... There's going to be blood everywhere!

[Langer]

Considering that my new fans frighten me, it occurred to me that someone might get hurt.

So I decided to add redundant safety protocols, just in case:

A bit direct, but effective!

[dragoonxx]

don't forget to get a Decapitation Hazard sign as well heh

UPDATE:

Today was an intimate day between myself and my scroll-saw. =)

I started making some carbon accents from .8mm sheet - I had a few of these sheets left over from an earlier project. Their intended purpose was the outer shell of the Acer Ferrari series laptop ;).

I popped out the stainless steel - and cut out a replacement on my scroll saw:


I made some more carbon covers for the I/O and the RAM.


And another for the RAID card, because it's PCB was green:




I also covered the ATX plug with a little cover - because I wont be needing it:


A little overview:


I made little circles for all the fan motors as well, but I forgot to take pics. I'll take some with next update.

Tune in soon for more.

wow that looks awesome

This project is beast!
