Recently I decided to upgrade my "power" machine's video card, so I took the opportunity to snap a few pictures...
Intel Pentium 4 Northwood @ 3.4GHz
2x 1GB Crucial Ballistix PC4000,
Asus P4C800-E Deluxe 875P + ICH5R
HIS Radeon X700 IceQ 128MB GDDR3 AGP 8X
M-Audio Audiophile 192 24-bit/192kHz 4-in/4-out
Western Digital Raptor 10k RPM 74GB SATA
GUP SmartDrive 2002 Copper
Plextor Px-716SA Dual Layer DVD-RW SATA
2x Nexus 120mm
The machine is running at stock speeds and voltages all around, with memory configured dual channel, PAT enabled, and showing 2-3-2-5-1T. Both Nexus 120mm fans are at 12v - I had originally intended to slow them down, but the machine is more than quiet enough now so why bother?
NOTE: Though I have no pictures of it, the side pannel on this case was replaced with one from a 3700BQE that I ordered from Antec. The major differece: No VGA vent or TAC duct.
Here you can see the wiring and setup inside:
Pretty standard, really. The only thing of note here is that the heatsink's fan is set blowing up rather than down onto the motherboard. I tried it both ways, testing temps and airflow patterns (using the incense trick) as I went. It turns out that the temperatures on the CPU, northbridge, and motherboard were identical. From my observation the upward direction seemed to create a more focused airflow pattern, so I left it set that way.
Here is the front of the case without the bezel:
Some modifications here. I cut out the front fan grill and replaced it with an aluminum filter screen. I then covered all other openings with aluminum ducting patch tape. The only openings left are where the bezel attaches and a small gap around the SmartDrive. This was deliberate to allow air to pass over the fins on the drive enclosure. I should also note that the power and hard drive LEDs were swapped for bright blue ones. With the machine being so quiet I needed to be able to see if it was on, and the stock dull orange LEDs just didn't cut it.
The case from the rear:
Notice the silicone EAR fan mounts, grill removed, and rubber trim. Also visible here is the exhaust port for the video card and the connectors on the Audiophile.
The system was tested using 2x Prime95 24hrs, Prime95 + CPUBurn 24hrs, 3DMark05, 3DMark05 + CPUBurn, and Memtest86+ 24hrs. The temperatures listed under "max load" represent the highest temp observed at any point during testing. The ambient temperature during testing was ~23C. Temperatures were monitored via SpeedFan and Asus AiBooster.
I don't have an SPL meter handy, so I can only offer my observaions. The machine is sitting in the computer compartment of my desk with the intake approximately 3ft from my ears. I have removed the front and rear covers from the compartment to allow for propper ventilation.
At 3am last night I noticed that I could hear my cat bathing on the other side of the room clearly, but could not hear any noise from my computer. Quiet enough for me
Here are some photos after it was all set up:
So what does everyone think?
