After quiet cooling for 2 x Opteron 270's

Hey all,

After quiet / near silent cooling for use on a Tyan K8WE (S2895) with 2 x AMD Opteron 270 processors.

Mainboard:

Note: Backplates are in use.

Thinking something from Zalman and looking for ideas.

The system is annoyingly loud now, and have 80mm to 70mm tunnels on the stock copper heatpipe heatsinks that come with the Opterons with Panasonic 80mm fans on them. (It is quieter than the stock 70mm with similar CFM airflow, but still too loud to use as a home PC).

Also after passively cooled PCI Express Graphics x16 video card, thinking:
- nVidia GeForce 7300 GS/LE
- nVidia GeForce 7600 GS/(GT ?)
- nVidia GeForce 6600 GT
- nVidia GeForce 6200 (TurboCache acceptable, but I'd like to know the specs and final performance before buying).

My last 6 vido cards, inclusive of my current Radeon X800XL, have been ATI, and I am looking to change back to nVidia.

This system won't be used for gaming much longer (its single thread performance isn't that great anyway ) and I do not want an ATI video card running on a nForce Pro chipset.

I'll build another gaming machine in 4+ months, and see what the scene is like then, with plans to upgrade it (game rig) to a DX10 GPU by April 2007.

Cool.

Ended up ordering 2 of these:

; for weight reasons.

2 of the copper ones would weigh to much

The SilverStone, upon having a closer look, positioned the heatpipes on the outside edges of any fans (they would get no airflow over them), and if active cooling ended up being required it would've needed 2 x 60 mm (loud, high pitched) fans.

Within 2 weeks my PC should be quiet / near silent.

I hope.
