How can we read/adjust the fan's speed? I've read (quoted below from Netgear forum) that four (4) different fan speeds of 2000, 3000, 3500 and 4000 rpm are available, but I didn't see them in the r47090 webif GUI (nor stock), and couldn't find CLI commands to change them either. The dd-wrt GUI settings under the Services/Services tab can turn the fan ON/OFF at the set temperatures, but seemingly at only a very slow speed (barely perceptible with wet finger to sense airflow, although flashlight at just the right angle also confirms spinning versus stopped).

T(High-H) - This means that when the temperature reaches this thresh hold the fan will kick in at at faster speed 4000rpm
T(High-L) - This means that when the temperature reaches this thresh hold the fan will kick in at at faster speed 3500rpm
T(Low-H) - This means that when the temperature reaches this thresh hold the fan will kick in at at faster speed 3000rpm
T(Low-L) - This means that when the temperature reaches this lower thresh hold the fan will kick in on the lowest speed 2000rpm

I guess I will have to revisit this, especially after I de-brick this AX120 I now have in hand and BS gets things sorted and can start posting test images.
I was chasing one AX12 too...interesting, do they have a wall mount option or only desk, as well as those have a fan too, i guess its a must...as a desk only option those ax12 doesn't have very cooling friendly design...as R9000 has...
I'm tempted to cut off some side plastics on my R9000, and leave it only with that metal mesh on the top...but so far wall mounted, using only 2,4Ghz radio with fan nonstop working R9000 doesn't get hot at all.. _________________ Atheros

Sorry to raise this necro-thread from the dead, but is there a way to manually toggle the fan on the r9000 to see if it actually works?
I just recently updated to r48081 and tried setting my fan temp triggers to 30c/20c. It doesn't appear to be turning, but I haven't rebooted the router again since the reboot for the firmware upgrade (do I need to?).
Well crap, never mind. I guess it's running. For some reason I thought it had a HUYOOOOOGE fan under that mesh grill, but it's just a tiny little 40x10mm job in the middle of massive heatsink. And yeah, it's almost completely silent.
First time loading ddwrt, the defaults were 60/50C. Confirmed fan does work with a lower setting. And then reading those who have it running all the time?!? I'm confused.
Being a retired senior computer repair technician I know heat kills. BUT mechanic movement (friction) also kills. So a balance is the best solution. So I've always placed an external high-quality 12-18vDC running at 5V near the hottest device. Much easier to replace.
This also helps hot external USB flash drives tremendously. Let it run 24/7/365. Just enough air flow but super quiet. Fan practically lasts forever. Replace every 3+ yrs because of dust buildup. Typical: 32/35/37 (cpu,wan,wan)
Anyone know what "normal operating temperature" is? Likely it's way way above 32. _________________ Current: NetgearR9000 r48865
