Atto R380 & PCI Fan noise

Just updated my Atto R380 to the latest driver. Flashed the card with the latest firmware and downloaded the latest Atto config tool. Running the card in an early 2009 8 Core Mac Pro. (OSX 10.6.4) Now I find that the PCI fan is running at 3000 RPM all the time. I called Atto teck and they said to try SMC Fan Control, however I cannot get this to work on my machine.

Is there a way for me to bring the PCI fan back down to 1500 RPM like it was before I updated the driver? OR am I asking for trouble if I lower the fan speed and just need to move the CPU to another room. Or think about getting a different card?

Can you replace the fan with a low-noise version that moves a similar amount of air? We spent a couple of days replacing all the fans in our edit suite computers and even some dedicated gear, like our waveform/vectorscopes (which are rack-mount devices that use your NTSC monitor instead of having their own dedicated one). It's amazing how much it reduced room noise. In two suites, we already had the computers in homemade isolation boxes (which also have vents and exhuast fans), so those rooms went from being annoying to almost silent. In the third, there's no isolation box but the difference in noise is still amazing.

We also have a two year old Apace vStor shared storage system and it's ONLY downside is how loud it is. It's in a large closet in our building (that also has sound absoption foam on the walls and door interior) that houses our phone and all networking gear, and I swear when you open the door it sounds like a jet sitting on the tarmac. When I brought this up to the guys at Apace and mentioned we replaced all the oem fans on our HP and IBM workstations with low-noise or silent ones, they asked for more info and that's one of the improvements they made to the unit.

BUT...heat is the number one enemy of hard drives and computer components, so it's important to maintain airflow numbers (or at least keep them close) compared to the original fans.

Oh yeah...fans are WAAAY cheaper (about $6-$10) per than buying or building your own sound isolation boxes. The ones I built, while MUCH cheaper than the commercial ones... still cost about $250 when all was said and done...and while they look pretty nice too, they also took me about a day and half to build...far more time than it took to replace the fans in each suite.

All of ours were in IBM and HP workstations as well as a couple of rack mount waveform/vectorcopes. I believe I got the fans from a place called EndPCNoise.com but just google silent PC fans and you can find a bazillion choices. All you need to know is the mm size of the fans you're replacing, the thickness of them and roughly the amount of airflow they move. You can typically find all that info right on the fans themselves. You also need to check the number of pins they have (usually 2, 3, or 4). Almost all the fans can be bought with whatever pin connector you need.

Hey, I have an R380 card, and had a similar problem when I upgraded to Snow Leopard. My Mac Pro under Leopard was very quiet, but when I upgraded to Snow Leopard, the PS fan in the Mac ran at about 1500rpm, instead of half that speed on Leopard. It took a while to figure it out, and I got help from the guys at Sonnet (I have a DX800 RAID). Here's the first email where they identified the problem, followed by the email describing how to fix the problem (and I did indeed fix it). Here's the first email:

----------------------
Helmut,

We don't really need to see the video as you've discovered a bug that ATTO didn't know about. My contact at ATTO got back to me about 30 minutes ago just before he was leaving for the day and explained what was going on. I just haven't had a chance to send you an email about it. The ATTO software installs a service that revs the fans up a bit to compensate for the increased heat folks found in G5 machines. This was adversely affecting the ATTO card in those machines. They discovered a hardware fix for this heating problem so that service was no longer needed. ATTO's software is supposed to remove it so the fans will go back to normal operation. For some reason, that service wasn't removed in your machine. My guy at ATTO is waiting for an explanation of how to remove it from the software engineer. It will probably involve deleting a plist file of some sort. He said he'll try to get that to me tomorrow. He wanted to call me today to let us know that something was being done.

So you've discovered a bug and hopefully ATTO will send me a fix tomorrow which I will pass along to you. It's strange that yours has been the only report of increased fan noise. Or at least the only report I can remember.

Now here's the second email which I followed and solved the problem......

Helmut,

Left a message for my contact and had this email waiting for me this morning:

Have him delete the file /usr/sbin/fan-controllerd

He may need to be root to do this.

The plist item is /Library/LaunchDaemons/com.attotech.fan-controllerd.plist

So delete both of the above and that should restore your fans back to normal operation. Email me back if you are having any issues with the above.

Hope this helps!

THANK YOU HELMUT!!!! I owe you a beer!

Yeah that worked like a charm. I could not find the file user/sbin/fan-controllerd so just trashing the plist worked. THis is great! Now the PCI fan is back down to 1K rpm. SO much better.

Thank you so much for posting

Best,
Chad

Any updates on this? I just installed the R380 and have the loud fan noise, but don't see the plist files mentioned.
Thanks
