fanless graphic card for Mac Pro?
I currently have an ATI Radeon HD 2600 graphics card in my several-year-old Mac Pro. The machine has been periodically freezing up the past six months, with increasing frequency, usually displaying graphics glitches (green and white checkerboard pattern, etc.) on the lock-up. I'm guessing that there's something wrong with the graphics card, overheating might have damaged it or perhaps something as a result of a sudden power outage we had last summer while I was on the machine. It's also possible that the machine is simply overheating as a result of adding a 4th hard drive last summer, up from the 3 I'd been using all these years. (A 2 TB Western Digital "green" drive selected specifically because it was supposed to sacrifice some performance in favor of cooler operation, btw).
Anyway, I would like to buy a new graphics card for the Mac, and my #1 requirement is that it be a fanless graphic card, because this computer's primary use is as an audio workstation, so I am willing to sacrifice performance in order to keep the machine as quiet as possible.
Besides trying another 2600, can anyone recommend a similar card, perhaps newer than the 2600, that would fit the bill? If you don't know of any fanless video cards, can you suggest one that, while having a fan, is notably extremely quiet?
Also if from the symptoms I described you think I'm off target in my belief that the video card is the culprit here, feel free to suggest other causes for the problems I'm seeing.
Thanks.
Mac Pro, Mac OS X (10.5.8), 6 GB RAM, 4 SATA drives (500/1/1/2)
