Now I am actually replacing Akitio PSU.  

I am looking at Corsir SF450 (SFX format).  It is 80+ Gold certified so it should run cooler.  It also has 92 mm zero RPM fan mode and should be silent during low and medium loads.  $90 price tag is steep, but worth it to rid of this loud PSU fan.

Only question I have is that I am not certain if the fan will line up with Akitio Node's PSU fan opening.

Thats not a half bad idea, My only gripe with the node is how loud it can get when everything is at idle. if you look at the tear down of the node that @itsage did and compare the PSU to the one you want to replace it with, it does look like it would match up but it is a little hard to tell without the measurements. Would be keen to try this mod out too depending on how you get on. Would you replace the front fan too?

I'd like to know why enclosures makers didn't consider to use TFX PSUs.

Ok.  It works great.  Fan cutout on Akitio Node and fan on Corsair PSU are both standard so they match.  

Unless I am running game, neither my GPU fan (MSI GTX 1070 gaming X) or Corsair PSU fan run.  Only fan running is Akitio Node front fan, which isn't too bad.  I will replace that with standard Noctua fan later.

Costs $ but silence is worth more to me....

EDIT:

These are modular cables.  It only ships with 2 PCIe cables so you will need to obtain one more if your GPU needs two cables.

@chocomonsters Thanks for the update! Glad to hear it worked out well, I think I will do the same in the next couple of weeks. In regards to replacing the front fan, How would one go about choosing a fan? I am keen to go with a Noctua fan, However I am little confused as to how it would all connect up? I see on the Akitio Node PCB that it has a 2 pin connector, however on all the fans I've looked at have a 3 pin connecter. Would I need to get an adapter or would i just be better off cutting the wires and connecting them up with the new fan, as I wouldn't need to worry about the 3rd pin in the connecter. I am complete noob when it comes to PSU / Fans etc as I've only owned Mac's so have never really had to look into any of this. Any help would be greatly appreciated.

@chocomonsters Looks great! I'm starting to rethink the power supply fan again. I really hate that it always runs.

I'm curious how you actually "turn on" this power supply since the ATX connector that sends the "power on" command is not used. Is the power supply always on when you flip the master switch on the back? Or are you using a paper clip trick?

I have ordered Noctua 120 mm NF-S12A FLX and 2 pin to 3 pin fan adapter from Amazon.  Will let you know how quiet it is once I get it.

NF-S is for universal case ventilation and quietness (NF-F is for heatsink and NF-P is for in-between).  PWN is for 4-pin control so useless for our use.  ULN maybe too slow and low ventilation.  FLX has 17 dB/A and 8dB/A.  

Just use 3 pin to 2 pin converter.  3rd wire is for a speed signal which won't be used in Akitio Node.

@chocomonsters, not sure but have you replaced the entire PSU?

The Node's standard PSU comes with a 12v 80mm slim fan. I replaced the fan with a SilenX Itrema slim 80mm fan. It's very very silent. Note the fan needs to have a height of 15mm instead of the standard 25mm or it won't fit.

The label on the PSU states "with fan sensor control", my guess is the voltage is going up depending on temperature. I measured the voltage on 3,6 volt without anything plugged in. Too low for the fan to start up but it started turning during benchmarks and stayed on after reboot. After cool down it shuts off.

To replace the fan you can easily open the PSU with 4 screws. Oh yes, please don't try this at home kids. The SilenX fan comes with a 3pin plug so I soldered the wires to the 2pin plug. You could also get a adapter ofcourse, but space is limited inside the PSU.
