Fan replacement for Akitio Node?
I've finished swapping out the PSU Fan with a "SilenX IXTREMA Pro IXP-52-11 80mm x 15mm" Fan. Made a massive difference with sound. Its fairly easy to do, You just need to be handy with a soldering iron to wire the new fan in place. I can't even hear the PSU anymore. The only fan I can hear is the fan on my RX480.
@DANgerous25. Nothing to install really. SFX format PSU is standard size that fits in Akitio Node. Unscrew and PSU slides out. No special tools needed. No need to open up PSU.
I chose Corsair SF450 as it was modular PSU that can accommodate 3 PCIe cables (one PCIe for Akitio Node and 2 PCIe for MSI GTX1070 gaming X). It is rated 80 plus Gold so it runs cool enough that PSU fan doesn't kick in ever. It only came on once during stress benchmarking. This PSU comes with 2 PCIe cables so I requested and received 3rd PCIe cable from Corsair. All PSU designed to use with motherboard will need "power-on" jumper with paper clip or pre-made jumper tool from Amazon. Just attach jumper tool to 24 ATX cable to power on PSU. This simulate power on-signal from computer motherboard and turn PSU on.
I also replaced stock Sunon fan with Noctua NF-S12A FLX fan yesterday. It is really quiet (17.8 dB at 63 CFM air flow with max speed setting) vs Sunon fan (29.6 dB at 55 CFM air flow) and moves more air than stock fan in Akitio Node. This fan can run at slower speed but I dont find it necessary. You do need a 3 pin to 2 pin fan adapter cable.
These are what I used.

I was thinking of replacing the stock PSU with the Corsair SF450, but it seems to only support two PCIe connections? Which slot are you plugging your spare PCIe cable into?
This is Fan.
Thanks to @Chocomonsters' advice, I've now received all the parts and I've successfully replaced my power supply, and also added a ThermalTake LED fan for good measure. Here's how it looks without the cover on!
Apologies for the PDF, for some reason the site won't let me upload as a JPEG even though the filesize is only a few hundred Kbs.
It has two PCIe and one EPS/SFX12V connections that are interchangeable. I obtained extra PCIe (6+2) cable from Corsair which can be connected to EPS/SFX12V. I used PCIe connected to EPS connection for powering Akitio Node and two PCIe to power GPU.
I found the fan noise a little loud so I ended up replaces the fans as well. Instead of soldering, I bought an adapter for the PSU fan and front fan (I couldn't find these adapters easily anywhere else). For the front fan, I used a be quiet! Pure Wings 2 and for the PSU fan I used a Cooler Master fan. I thought about using the SilenX fan, but I found a lot of negative reviews about the build quality. The replacement fans work very well and it's very quiet now. Loudest fan is now the GPU fans (and when laptop is not in use, PSU fan is very quiet).

This is interesting that people complain about the PSU fan being louder than the front fan, I'm beginning to think my front case fan has a defective bearing. It's not a typical bad bearing sound, but it is definitely the loudest part of my Node and isn't a fan noise but more like a "purr."
I tried running with it disconnected to see if the GPU would maintain its cool, but unfortunately it did climb over 80C and with the fan plugged in it runs in the high 70s under load. I guess I'll be buying a replacement. Also good to hear about the PSU replacements, I may do that down the road but for now I don't mind the PSU fan noise.

@drax392 I agree: in my Node, the front fan is definitely noisier than the PSU fan, also with a constant "purr". I think under load, the PSU fan gets quite noisy as well though. I will replace both fans in time.
I replaced the original front fan in my Akitio thunder 2 with a dual noctua fan setup at slower speed,
the "siren" went silent and I have better cooling as well.
Noctua is highly recommended.
