I recently got an s7 antminer but I haven't been able to run it full speed due to how loud the fans are. So this got me thinking, could I build a box that channels out the heat and reduces the noise enough to run at full power?

Here is the general idea i have:
-A wooden/plastic/*some material* box. It will be large enough to hold the s7 with some airflow room.
-On the inside of the box, I will have some foam acoustic panels.
     -Yes i know what your thinking. "Wont the foam cause the heat to be even worse?" well that's where my next ideas come in.
-Some duct venting inside of that box to bring the hot air directly from the output of the s7 fan to the outside of the box.
     -This duct can then lead to outside to dispose of the hot air.
-Some more duct that will allow the s7 to draw cool air from outside of the box.
-All of the above ducting will have bends and be sound insulated to allow airflow and still minimize noise.
-There will be additional fans on opposite sides of the box. One for intake and one for output. These will help to cool the inside of the box for heat that escapes the two main fans.
     -Just like with the main s7 fans, these additional ones will have ducting and sound insulation to minimize the noise.
-All the intakes and outputs of the fans can be grouped together accordingly so it can have one large intake and one large output.

Does anyone here have experience with something similar to what I am thinking? Any advice you care to share. Potential problems. Any input can be helpful and would be greatly appreciated.

They can be very loud especially with the stock fan .

I had a single G839 Noctua NF-F12 Industrial PPC 3000RPM PWM 120mm high performance fan on some S5s I was running a while back and they were pretty effective at cooling and were much quieter than the stock fan .

Hi Guys

Based in the UK and have a few S7 miners, one fan is starting to make a noise so i had a quick look on Ebay for one and was SHOCKED to see only US stockists at a stupid price !!!!!

http://www.ebay.co.uk/itm/Replacement-Antminer-S4-120mm-Fan-4500rpm-20in-cables-4pins-connector-/231569988051?hash=item35eaa599d3:g:xysAAOSwpdpVXtT5

Is there a cheaper option ?

Anyone advise ??

Thanks

Can i use the delta fan tfc1212de 3.9A on antminer S5 or the 3.9Amper its so much for S5 controller?
How else controlling this fan for only 3.000-4.000rpm and not full load at 5.500rpm?
Thank you!

I started mine up today and it was like you had turned on a vacuum cleaner- heck, even my vacuum cleaner is quieter. I had to put it in the basement and powerline it in the end, but are these units supposed to be so loud? I had a hard time even being in the same room as the miner. At first I thought it was my PSU making the sound but I noticed a few seconds after I plugged in the power to the PSU the noise would take over, and air was running through the miner.

It's really not an issue for me as I can plop it in the garage or basement and it'll get much much more quiet, but it's just a tad bit annoying.

So i recently acquired an antminer s7 with bitmain's apw3-12-1600-b2 psu and immediately realised that it was loud. a bit too loud for my liking and i wanted to, somehow reduce the noise level, to make it bearable for me and the people around me.

I could possibly purchase 2 fans that'll have similar rpm, airflow, etc. I'm looking at the noctua nf-f12 pwm industrialppc-3000 as a candidate. another way is to build a noise-reducing cabinet (much like the one constructed by the one showcased in Fitzy's post here: https://bitcointalk.org/index.php?topic=1194785.msg13157846#msg13157846)

I'm no expert in the bitcoin mining community so help would be appreciated, thanks!

The 6000 RPM delta fan and the Ultra Sleek Vortex 14 are in totally different classes, it won't work.  Delta is doing 210+ CFM at max speed, the vortex only 98CFM.  There is almost nothing comparable to Delta fans on these things.

There's a fan called the Scythe Ultra Kaze that runs at 3000 RPM, pushes a ton of air and is slightly quieter, but it only works if u have the non-autotune S9 and can downclock the frequency a bit.

Has anyone ever tried to use another fans to reduce the noise? I thinking about use some Prolimatech Ultra Sleek Vortex 140mm, I know that its 166 m³/h instead of the 188 m³/h from the default ones, but I'm talking about 18 dBa at full speed!
