So for a while now I've been happily using a Noctua for my system fan (temps read rather high when the aircon is off) and a Zalman for a CPU fan (runs great). This is all on my RNPP (see my sig for details).
I decided to swap the Noctua for a Noiseblocker NB-eLoop B12-4 Ultra Silent Bionic Blade Fan because it can ramp up to faster speeds and push more air. I updated to 4.2.23 just before doing this fan swap, let the RNPP reboot and saw that all was fine.
I plugged the Noiseblocker into the same port ( http://i.imgur.com/pytAE13.jpg ) and after starting the NAS, the new fan spins up just fine. I go to the Health page and for some reason the Noiseblocker stops spinning randomly with the error "FAN SYS failed" and "out of spec" ( http://i.imgur.com/64foOaT.png ) and I can see the old issue whereby Health reports FAN SYS, FAN CAS and FAN CPU. I went back and re-installed the ToggleSwitchProCPUFan_1.0-x86.bin addon twice and finally FAN CAS disappeared (see previous screenshot), yet the NAS keeps turning the Noiseblocker off.

Is the Noiseblocker honestly 'out of spec' in terms of RPM/power draw for the RNPP? I wouldn't think so!
I wouldn't mind a fix that led me to use USB/external power to keep the Noiseblocker running at full speed since I can live with the added noise.

Judging from what a quick Google search showed, your new Noiseblocker fan draws 320mA at 12V. That's more than FAN2's 250mA max, so yes, it's out of spec.
The Noctua fan you switched from draws only 1.08W at 12V; its current consumption will remain within spec across its entire RPM range.

Well, that certainly wasn't what I was expecting. But thanks, at least it clears up what is going wrong.
Now I need to find either something like this ( https://dx.com/p/usb-2-0-to-sata-ide-5- ... lack-10113 - it shows an img where its got sata-->molex, I have molex to 3pin) to power the fan externally OR an alternative fan that can push this much air at 250mA or less.
I would think that the RNPP could simply provide 250mA and the fan run at the speed it can with the given power, since both the RNPP and the fan are variable.
When I replaced the fan in my Pro Pioneer power supply, I chose to power it directly from one of the 4-pin power-supply plugs so I could experiment with its low-noise adapters without having to open the PSU case every time. The Noctua NF-R8 fan came with an appropriate adapter; you can find one by searching the web for 4 pin to 3 pin atx fan. Shouldn't cost more than a couple dollars.
The only thing is, if you do it that way you'll no longer have variable-speed control for your case fan, so you'll have to run it at its maximum speed (and maximum noise level) all the time.

Well, the ReadyNAS designers chose the stock fan because it provides sufficient cooling at low-enough current... And with variable-speed control, it'll probably be quieter than the single-speed Noiseblocker fan most of the time.

Yeah, it's unfortunate that it doesn't work that way. And even if it did, you wouldn't be able to lower the fan speed without overtaxing the resistive fan controller. Best to switch back to a lower-current fan like the Noctua or the stock fan.
Why'd you switch from the Noctua to the Noiseblocker in the first place? It wasn't clear to me from your initial post in this thread.
I needed more case cooling as my temps were crossing the 65*C threshold, I live in a hot climate and having 33* ambient temps is not unusual. While I'm using an air cooler in the room (cannot run the aircon 24/7), I needed a bit more cooling in the RNPP case.
I haven't had a chance to look inside the RNPP, does the Power Supply have a spare 4-pin Molex? That would do the job for me, since I have a 4pin-3pin adapter already, or at most could source it quite easily.
My concern lies in that I'll be going from a 2 pin to a 3pin, hence I will be making the assumption that Yellow-->Red, Black to Black, White will have no connection. White is the Signal connection.
Just to clarify, I'm using the Yellow/Black pair from the Molex because thats the 12v side of the plug. The Black/Red is typically the 5v side.

In all fairness, the new setup ought to run a bit warmer due to the change in position of the NAS, but can't argue with results! (So long as they're accurate).
