Here's a Scythe Ninja duct made using only what was included!
I kept pondering what I had lying around that would be the best fit for the least amount of work, and finally settled on this.
The system is an Athlon64 3500+, Asus A8N SLI Premium, XFX Geforce 6800GS w/ Zalman VF-700Cu, Samsung 250G SATA2 Spinpoint, powered by an Antec NeoHE 430, all in an Antec SLK3700AMB that held my previous P4 system.
There's a 120mm intake fan on an FM2 running between 5 and 7 volts, and the 120mm CPU fan attached to the motherboard CPU fan header. The VF700-Cu is on the 5v leg of the adapter.
Prior to ducting I had very good temps, but wanted to see if this would improve the VGA temps some by flushing air more directly out of the case. Now to test.
Update: test temps!
* no exhaust fan
* cpu fan at 1440rpm (so says Speedfan)
* intake fan turned all the way down on a FM2 (5v?), Speedfan says 0rpm
* ambient room temp 22c
* temps are taken from nvmonitor, except hd which is taken from Speedfan
after about 10 minutes of burnk7.exe at high priority
after about 15 minutes of idle
after 15 minutes of Quake 4 demo play, 1280x1024 all settings on high
Update: thumbnails and better pics
I've tested isolating the hard drive using an oval gel wrist wrest, and I can now easily dampen what's left of the vibration in the side panel with my fingertips. I'm on my way to get some Stretch Magic.
