This little nas does have all the attributes of a standard computer. IMO, this is a fine piece of hardware, as it always is with netgear but the software, downside is pure crap.Īfter a first try with readynas OS 6.1.6 with has been ported to older hardware by community, I was steel unsatisfied, less but still crappy. Seeing it's really reliable I decided to build a home made nas with motherboard and disks, migrating data from my old netgeat readynas rndu 4000. The user likening the fan noise to a hairdryer is 100% accurate.I'm following for few month now this fantastic project, and it's time for me today to bring contribution.įor 3 months now, I'm testing xpenology both with trantor boot and gnoboot. I'm only drawing 19W of PoE, though it was also this loud when it was sitting by itself on a glass shelf in a cold room with only the power cable plugged in. The casing is cold to the touch, the temperature near the intake fan is 79.8 degrees F, the exhaust air is 81.3 degrees F, and I can hear the fan whine in every room on that floor. I have mine (24 port POE) in a well-ventilated laundry room on the second floor of my house. This fan is still unacceptably loud under firmware version 1.0.4.
Often those switches are within an office where it could be a problem it is too loud. Is there any official solution for the loud fan? What a joke! They ship devices with an undocumented firmware release. The file or changelog were never added and it's been close to a month now.
Pretty sure you have to be cloud managed to get it still. I wonder if anything is planned with new firmware releases to fix this bug. I have purchased 1930 24G PoE +370W JL684A and it is very loud as well. I would definitely change my order if this were fixed. Is this still a thing? I intentionally bought the 8-port for home use over the 24-port due to the reports of intense fan noise 24 hours a day on the bigger switch. It's been almost 6 months since I started this thread and it does not seem that Aruba is listening. The noise get annoying real fast and I have since switched back to my older Netgear switch. My POE devices draw less than 30w combined and it still sounds like a hairdryer on high all day. Still an issue as of the latest firmware, v1.0.2.0_125.
#Readynas fancontrol no pwm generator
Now I am planning to rebuild my own case, set the fan to the left top, so the airflow is as normal and the PTC / NTC measures the outtake temperature and I am planning to build (or buy) an small frequency generator (NE555) to simulate a solid and higher fan speed to the Switch to let the switch be in normal state. But at this moment the 1800rpm are totally overdosed with this 12cm fan and you can hear it and see in its power consumption. When I pull out the PIN 4 (PWM control for the fan) the fan accelerates to its maximum speed (1800rpm) and the switch goes back to normal state. Now the NTC / PTC is only measuring the intake air and can not react on the switch load.Īlso the problem at the moment is, the Tacho signal is so low due the low fan speed, that the switch interprets the fan as defective and displays an error (red blinking light and fan error in the logs). Normally the airflow is from left to right, the fan blows the air out of the switch and the NTC / PTC next to the fan can see how much heat is produced by the switch and can control the fan speed. Only thing is, the air flow goes into the other direction.
This fan runs at approx 1000rpm and generates much more airflow than the small 4x4cm fan at much more rpm does. It is blowing there inside the switch and the air flow is coming out on the left side through 2 holes. So, I decided to build my own upper case with a 12cm x 12cm hole on the top right with an arctic cooling 12x12 4 pin PWM fan. The connector's pinout is compatible with any mainboard / intel fan (4 pin PWM).įor test purposes I Connected an genuine intel CPU fan and it also runs normally. Next to the fan connector there is an PTC or NTC (blue, very small part) when you touch it (and warm it up with thefinger) the fan speed increases.īecause the fan does not change the rpm during boot (as it do on old, solid HPE Switches) I am sure the control circuit is a dedicated and analog circuit and the os of this switch can not control the fan speed rpm. So it's loudness reaches from very very loud to very super mega loud! I disassembled the switch and the part number on this fan shows that it is build for 4000 - 10000 rpm. I ordered this switch for me and myself and for me the fan was also too loud.
