Nighthawk M1 custom fan
Hi everyone. Just wanted to share a little fun setup I made out of boredom. I found a spare slide switch and a 5V fan in my electronics box and also a 2 AA batteries socket connected in serial. I soldered it together and insulated the wires in a coating and stuck it beneath an opening in the lid and positioned the small fan inside the square, where the Li-Ion battery was supposed to sit before I detached it. It now runs on 3 volts providing a refreshing stream of air to aid the logic board in receiving its heavy loads from the telecommunications network. :) You could actually make it spin faster by using three or maybe four AA batteries without burning out the circuitry (I have tested it with as high a 12V battery, and it did tolerate that for several minutes). You could even get a 9V battery and a just slightly larger fan, or you could perhaps use a tiny lithium polymer battery and make a compact solution completely inside the device itself by using up the dimensions from the hollow battery compartment! I have noticed that the modem gets really hot when you pull torrents down for hours and some report that the DC current will decrease in case of overheating and start to drain the internal battery down to zero, while others report that using a fast charger (2.4A and up) without internal battery will less likely make their modem reboot, so for those people, this could be an adequate option to avoid removing or poking holes in the cover lid and mounting a regular sized cooling fan.
Moving CPU fan connector to IO card from Mobo
I am working on my Biz Pro system that died after a couple quick reboots following a power outage that lasted longer than the UPS did. When researching the issue, I found this article: https://kb.netgear.com/12240/Service-Action-for-x86-ReadyNAS-Pro-CPU-fan-speed-control# It mentions some systems were wired wrong, i.e. the CPU fan connects to a 4-pin connector on the MOBO, and instead, should be wired to the IO card to get fan control based on CPU temp vs. running at full speed. The article doesn't explain how to connect a 4-pin connector with 4 wires in it to a 3-pin connector, i.e. one of the four fan wires wouldn't be connected. Surprised that detail was ommitted from the article. I am guessing only 3 are needed, ground, power, and a third one for the speed setting. The system fan mounted on the back has 3 wires, red, yellow, black. Presumably the red is hot, black is ground, and the yellow for fan speed. The CPU fan wiring is blue, green, yellow, black. If I don't get this figured out, I will plug the connector back where it was and pretend I didn't see the article :) Thanks
ReadyNas has died? Only works the fan at full speed...
Hi, I have this NAS RND-2D since some time ago and now suddenly only work the fan when I turn it on. None of the leds or network are working, only works the fan at full speed. As soon as I connect the power cable, the fan run at full speed until I unplug it off again, doesn't happen anything else, Even after 10-15 no LEd lights up. I have tried others HDD, pressing all the buttons and reset, but I continue without any difference. I will really appreciate any help to fix it or know if my ReadyNas has died... Model No: RND-2D Model Name: RN10200-100EUS FW: v6.0 Thanks for your help. All the best.
