I call it The Fortress.

Inspired by:
“Blessed be the LORD my strength which teacheth my hands to war, and my fingers to fight: / My goodness, and my fortress; my high tower, and my deliverer; my shield, and he in whom I trust; who subdueth my people under me.”

Was a bit to lethargic to take out my better camera, so just took pictures with my phone.

Here goes.


Front - Without Flash:


I know I know, the white DVD-rw is killing the look. I have to, blacken or chrome it. Trust me.



Front - With Flash:


Cut out the thin wire mesh. in front of the HDD rack. Thats is a Thermaltake 120 mm Green, 0.8A 88CFM I was inches away from unriviting and turning that rack 90 deg to a more conventional flow style.



Bottom



Cut out part of the Mesh for a 92 x 38 mm 140Cfm 2.5A fan. Running it on 7V. Added a grill so it wouldnt take in any paper if that was nearby.



Proc - Intel q9550 Lapped


Went for flatness. High Finish is actually not necessary.
Made a 2-3 deg difference on load.
Running it at 3.8Ghz presently.



Back Wire Management



An Ultimate 700 has tentacles roaming about. Hiding them was a challenge.

The sata cables have been improved. But well, after the pic :(



Rear



Cut out the steel mesh for better airflow.
Will exchange that black tape with silver lining ( shown in side panel image below) later. Will also add a grill.



Back - Panel


Chromed :p



Fan with grill. Blowing onto the CPU region on the MOBO. Grill not cut. Still. Made 5 deg difference on Load.



Notice the slits cut out at the HDD region. I figure exhaust there would help. The HAF 932 always has the lowest HDD temps. Perhaps this is why.


3 Empty 5.25" bays

Previously was running a 120 mm x 2 Push pull setup.
Air flow was bad. Went through my physics book and realized why. Minimum distance between fans required.....



Instead got this 92x38 monster, up and running at 7V.

Notice the wire management. Zero obstructions. Flattened the IDE cable and all others with it alongside the casing. Used tape and zip ties to tight it up a bit.

Great wind tunnel.


Will try and replace this with a 120 mm similar speed monster.






Top



Cut out the steel mesh and have 2 140mm 1200rpm 60 cfm aerocools blowing downwards.



PCI Card covers



REmoved all unused PCI covers since I use positive air pressure. The wind tunnel and another fan below could use directional exhaust.



Power Buttons for the 92 mm noise machines.


Used a drill machine, and sandpaper to make holes for these.



HDD Rack Cooling.




Dont worry, dusted it before permanence.
To ensure better flow over HDDs.



Just have 2 at the moment. Will have 4. 4 x 1TB WD Blacks.

2 x 2 Raid setup intended.





Inside

Yes im a big wire management freak.



You see the Cool It Domino. A push pull config on the radiator. Using a intel HSF fan to push into it.







That fan is cooling the Northbridge. Northbridge's thermal pad was removed. Used as5. 10deg decrease. My NB was running maddeningly high :S


You can also see the intel HSF fan clearly in this one. Its with two legs only, cut the legs that would have touched the radiator.


Side Panel Inside.

Okay I spent quite some time on the side panel. Had to cut 3 holes in it. I like an airy machine. I dont mind dust, I own a blower and I have weekends off ;)




Notice the small hole, thats a PCI slow blower picking up hot air expelled from the Vid card. Might get a Dual thickness blower (Dual PCI slot) soon.

The transparent fans are TWO CM 39 CFMS taped together in a single direction. They exhaust air out. From the VGA card.

I consider it a feat to idle the 9800 gx 2 at 52 Degs celc.


The black blow hole is a 140-120mm adapter. and two 40 CFM CM fans taped together in a unidirection. Cooling HDDs ( NOW get the side slits ! ) and also providing Me a fancy looking thing on the outside.



Also usually keep my wallet and cell phone on it so .. Its handy.



The 120 mm green Thermaltake 88 CFM cools down RAM, as well as the Aerocool from above.

Things to buy would be. 2 1TB WD Blacks. And perhaps Corsair Dominators. Not that DHX arent good. But there is this FSB wall that I am hitting. I have a feeling its a DRAM speed wall.


Things to do. Buy thin 2mm acyrlic and drill a hole in it for the window ( need the hole to control the Domino ALC).

good work mate. and 140 CFM is insane! i wouldve put that on exhaust but i see you prefer a positive airflow.

also the aerocools should be exhaust non? since hot air rises..

Convection currents for steam (hotter than this air) are 15-20 cfm.

That and... I have an AC right above the pc. I much rather turn that on, when I render or game.

Even on AC off, the temps are somehow better this way.
I did have these fans the other direction in the start.

Mobo would rise too much this way. Going liquid cooling for the cpu meant that the heatsink design for the mobo would fail. No air moving there. Needed air to move around there.

:p Well I do have a DSL modem mod planned. Damn thing runs too hot :p

also, did cutting out the honeycomb grills make a difference in temps? and what exactly did you use to cut em?

those aerocools are seriously badass. i like.

To cut out the honeycomb, I used cutter pliers. Smoothened edges out with a file, and then sandpaper. And then Tape.

Difference in temps, dont know. Cut the honeycomb out as soon as I got the fans. But yes DEFINITE increase in CFM.
Look at it this way. CFM is rate of flow of gas (velocity) in a fixed area. Restricted that area and you will get less CFM. These honeycombs are atleast 1/3rd of the total area.

good job there bro, i m pleased that u lapped ur cpu as i did and took the risk for cutting some degrees from the max temp. Well y ddnt u get a perfect finish btw, its not that hard. and how far did u go with sandpaper grits?

Ali, I went till 1200, but I didnt use water. I go for perfect. Polish never really pays off. You over compensate and loose flatness. And I was tired :p


I did chrome the other panel. :p Ask shajeel what happened. A fly came and sat on my bloody paint job. And then two mosquitos. The chome can only lasted two panels. I removed the bugs and then sprayed chrome only to realize that the spray had gone grainy (end of can). ARGH. :p

So yeah.

As for the Excess of blow holes of fans. A 9800gx2 machine with raid :p

You NEED cooling :p

I personally like the idea of a wind tunnel popping outta the side of a casing. Its like those muscle car intakes. I'll spend more time on this once I feel dissatisfied. For now, just need to get the 2 black 1TBs. Somehow they are short all over the city. (and lahore too). And then its a rest.

Hmm Okay. So ive worked on the side panel. The one I sprayed black. Ive sprayed it black, pics will be up in a few days.
As for my infamously hated fan tunnel that juts out the side of my casing. It not has a closed box look, and will soon be painted.

Will show you pics soon! Cant seem to find the data cable for the phone :S or the bluetooth dongle.
