The Zen of Air Cooling

…and don’t have a cat.

I have a 22 LB maine coon , 10 months old, named Archer

no issues with him tearing things up, → he loves music, classic cars, motorcycles , daily walks on a leash, and Italian food.

The factory short tiny heatsinks are poor at dispersing heat, just like the gigabit chip heatsink (see above in the thread). So I found a company that made them specifically for this board in a more effective size/ design

I modified / edited / rebuilt the CPU heatsinks
I made from scratch the gigabit chip heatsink
I bought, premade, the mosfet/voltage regulator heatsinks

This just reminded me of the “seeing eye cat” stories on arfcom

so I added the upgraded heatsinks, overall result nothing too spectacular, those components are running 7-12C cooler, so I think it was worth the effort:

combined with the edited/improved cpu coolers, the cpu heatsinks have a a full copper plate to completely cover the supersized 9684x’s footprint

The copper plate is 5mm thick

heatpipes and fin adhesion was improved

more fins were added to the full 120mm

combine with 350-3000 rpm phanteks t30

and outcome (quiet silent and cool running, even under load its not obtrusive)

If you ever decide to go with a 140mm tower cooler, the Sanyo Denki 140mm 9RA fans are the best “quiet” fan available on the market that can still scale up to high performance.

Compared to the brand new Noctua NF-A14x25 G2 fans just released, at 1250rpm a 9RA1412P1G001 is quieter, makes 40% more static pressure and 15% less airflow; although behind a heatsink’s finstack the Sanyo is also going to flow more air than the Noctua too.
On top of that the Sanyo scales to 230% of the airflow of the Noctua and over six times more static pressure at a louder volume if needed. The downside is the Sanyo costs about 50% more than a Noctua and is thicker.

Noctua fans overrated, still good but not otherworldly, the real magic is their heatsinks

I don’t mind it THICK, ….my T30’s are THICK

Noctua is definitely overpriced and over rated

I too was a believer for many years, - took guts to venture outside of the zone and look at what was out there….

I’ve even found some Chinese 120mm that are similar blade design as the new noctua and the same sort of material but also ship with the second fan inverted and counter rotating for the same cou cooler set up

Yep, nictua overrated and overpriced

Looks like a nice fan indeed - and it’s not even poo poo brown (a plus)

Sanyo is very common inside servers and switches, for a reason, I assume.

Yes. I don’t think I’ve ever seen the 9RA fans in “normal” computer equipment though, supposedly they are targeted for use in medical equipment that needs to be quiet, which conveniently overlaps with home PC needs.

Yeah I’m using some in one of my home servers.
Unfortunately I didn’t properly check that I’ve ordered the correct product code the last time.

The one in the front ends with product code G0011 (non ribed frame) the one in the back ends with product code G001 (ribed frame). Problem was fixed with oscillating tool :slight_smile:
