How to silence your d8b's PSU

[zetell]

Fractal Silent Series fans... dead quiet. I've had them in my D8B since the summer 2013 along with a CF drive assembly. I'll definitely have to agree, the IDE disk drive is anything but quiet.

I've also done the CF card upgrade and everything is dead silent. When I did these upgrades (change of fans and CF card) 5-6 years ago I was happy with it.

But now I've started to think it may be too little cooling coming from the fans as they don't really move that much air.
I don't know which fans you have installed, but I checked the 50×50 and 80×80 fans from Fractal and they don't have a larger air flow than the ones from NoiseBlocker.
Maybe I'm overthinking this, but it would be interesting to hear if anyone have experienced any issues after installing these low-flow(but silent) fans?

I've done another temperature check as my previous figures were from memory, my studio is around 23deg, I've had the desk running for two hours, the temperature inside is 35c.

Here's the gauge, has anyone seen one of these on a CPU, just wondering if it was a later fitting?

[zetell]

No, new to me.
Would be a nice and handy feature ti have though.

Is that picture showing the HDR?

[Phil.c]

Yes, one of my HDR's above it, I have three.

I ended up with a "NB-Multiframe S-Series M8-S3" fan for the power supply.
Found the datasheet for the original fan installed in the d8b PC and the airflow from that is 65 m3/h.
The M8-S3 from NoiseBlocker is 59 m3/h, so it's only 10% less.
For the CPU I installed a Saunon fan (MF50101V1-1000U-A99). Airflow for this is 23,6 m3/h. It do make some sound (still less than the original ones), but I could not find a fan providing enough airflow if I went for a supersilent type. Maybe a more silent model/brand will show up in the future.

I ended up using a Arctic Cooling Copper Silent 3 / copper lite cpu cooler.
It's the biggest and quietest cpu cooler I found that works with the CPU unit. I did replace the fan with a 80mm noctua fan - plenty of airflow, and dead silent - no chance that will overheat
It's a bit too high for the HDR though, unless you do as me, and find a different location for the small pcb board above the cpu socket.

I also used an old Acrtic Cooler fan with 80mm diameter that I had laying around, and printed a fan adapter from 50mm to 80mm using a friend's 3D printer. A larger fan can produce more air flow while remaining silent - you just can't do that with smaller fans. So a mechanical adapter you can 3D print yourself like these really helps.
