So, one of the reasons I finally created an account after so long of only lurking is that I'm thinking about buying some mining rigs. Thing is I have a "personal" desk as a masters student in my uni and could leave a pc there (with free energy of course), but the room has other 12 desks and people can't be bothered with the noise. Of course some noise would be ok, but it had to be something annoying only at very closerange.

But would using 2 cards in a silent case for example: 1) be really silent; 2) manage to be kept cool enough; 3)be worth the trouble?

About 3) specifically, I was thinking about, for example 2 rx570, which according to whattomine, profit is about 30% higher with free energy, in the long run it's a lot but if the costs of making the rig really silent and cool (good silent case, coolers and eetc), if even possible, be too much it's of course better to keep the mining rig at home.

I was thinking about this case for example,

Anyone has had experience with this?

You can go with a good case which is sure to have minimal noise. Corsair is one of the best brands but that case is a mid tower.If you truly want a super silent performance with up to 4 graphic cards inside I recommend you the Enermax Thormax Full Tower case.

Just google it as I am at work and I am using the phone because spies are all over me as in any other company I think.

well I was thinking about something more lowprofile, of course I don't want people to know I'm mining there, so I need a good case that looks more like an office case. THis Carbide silent series has a full tower too

But wouldn't putting more than 2 cards be exponentially louder and hotter for a closed case? I said only two simply because of that, but I don't really know it to be honest, can't find any tests about this,

Dude, are you quite sure that will be a good idea?  a good silent case can cost you a lot, like 150-200 dollars, are you sure that spending such amount for money is a wise idea?  literally you are thrown away  half of rx570 card?
The best option is to set up an open rig, the fastest and cheapest way to start farming

Some way, You may lower noise levels on GPU mining rigs. However you can not make it "0"

I do not recommend any mining rig, even small, in your bedroom.

Because noise makes people feel very bad and anxious. You will lose more than you make.

So, those Full-tower case are camouflage plus to reduce noise that produced by the card, right? You were doing the right thing for those two things.

But,
You will be troubled by heat. That standard case not designed for mining process, even if your cards use a water cooling it wouldn't help, instead will cause noise that produces by radiators fan.

You need an open-air rig for mining (like above said), nor a lot of fan for the closed-air rig (with a good airflow system of course)

You have to water cool the case and the heat will not be a big problem , both corsair and enermax cases offer support for cooling radiator. In a full tower you can put up to 4 cards but I suggest max to add three to keep the noise at a comfortable level.

Nah, Water cooling needs a radiator and radiator fans. I believe those fans would produce enough noise to mess up OP's camouflage.   :D

But yeah, I agree that OP needs to test it. Will be better, but It will cost more.

get a Vega Liquid and you will be fine

Watercooling is a good solution (but expensive).
The other solution is to try with GPU max fan speed limit and temperature limit (in claymore or afterburner).

Try to have the max distance possible between GPUs and add silent FANs to your case to have a good fresh air flow.
You will probably not get max hashrate as the temperature limit setting will drop it but this is a silent solution.

Also hide your connection by going through a VPN.

Happy mining,


admin@rigproxy.com

He said "of course I don't want people to know I'm mining there".
So he wants to mine stealthily without being discovered by others or university network admin.

I am also curious about it.
Would be better to explain it in general (not related to op's case). Since you have those kinds of service, right? As far as I know, using VPN will increase latency, means more steal shares, right? May you can explain more, besides what I told.

The VPN will indeed increase the latency affecting the time to get job, time to deliver share and also time to restore connection if your ISP network quality is bad. So more stale share probability I confirm.
Assuming the university has probably a good connection to internet and considering the will of OP to keep its mining rig secret, I could only encourage him to use a VPN despite the counterpart of latency (because of a longer network route and the VPN transport layer added over TCP/IP), risk of more stale shares, ....

Rigproxy.com is not a VPN solution but a proxy. When you go through a VPN (online pro service, or at home with RPI/linux) or any other tunneling solution, the admin can only see your VPN target IP.
If you connect directly to Rigproxy, the network admin may know that you are mining so using rigproxy won't help for privacy and was never made for this purpose.

There are many ways for the school administrators or network admins will find out what you're up to. As a masters student, don't risk wasting your education. Just mine at home and avoid the hassle of dealing with the repercussions. Mind you, mining without paying for electricity is stealing. Stealing is a crime.

Big like for that

Ah, I thought there was something new on VPN using, while mining. So, that was only for hiding us. It may relate to OP's condition that wants to be a silent miner.

OP
How about the room size, by the way? Those two cards are more than enough to heat a small room. 12 desks, right? Maybe 13 with you, seem like isn't too small. I'm sure people near you can feel it. Day by day more heated than usual.  ;D

Did you plan to run it 24/7?

I never tried such, so can't say, but not in doubt of its possibility.

Noise is very relative here.

For some a RX 470 can be silent and for others noisy.

For some an Antminer S3 can be noisy and for others quiet.

If you want it to be as silent as possible only way is to get a water cooled setup. However that takes up tons of space.

However water is the best way to remove heat, since it has excellent thermal properties.

Worth the trouble, probably not. Although the free electricity is definitely an advantage. The trouble is not in building the rig and making it silent, it is if somebody from the University finds out you're "stealing" electricity for profit because you're mining cryptocurrency. I'd say that risk alone is certainly not worth it.

Very well said. Ask yourself if you want to risk your education for a little money.

Silent mining is possible.

Take 6 x 1050ti KalmX, PCI-E Powered Riser, a nice power supply and 3 low noise fans.
For the CPU (G4400T or some others) you should take the arctic alpine 11.

Each 1050ti KalmX needs 66 Watt, but depends on the coin.

You will have to deal with 400-500 Watt Heat....

Silent mining is ez, basically you have 2 options:

1) Watercool your rig so that the radiator is placed outside of your room (I'm using this solution with my reference R9 290 cards). Only PSU and CPU fans are making noise. (May add pics later)
2) Submerse your cards in mineral oil. This will provide you with almost 0dB solution but your GPUs will be SOAKED in oil (very hard to clean off later, also some plastic parts will corrode away/become extremely fragile).

thanks for the answers guys, I'm currently doing some stuff but I'm going to reply soon

I will soon be releasing a number of free bitstreams to mine with FPGA's with better ROI's than GPU's, and if you want silent mining you can use the Nexys Video card (XC7A200T FPGA).  Be warned, you can only mine Keccak (Smartcash, Maxcoin) and SHA-224 (Bismuth) profitably, but the card draws minimal power, needs no fan, costs $490, and makes around $2.11 per day at today's prices which is more than many GPU's.

Sorry, i think you can not mining in silent. Because what as i know, mining need powerful rig if you want get more income. But if you need just for education, its okay you run silent mining.

you can easily silent mine. I have fractal define XL case with 2 gtx1080 and it is soooo quite. But I had to cut the power limit to 61%  :-[

Mine monero or sumokoin. They have energy efficient algorithms, which means no heat.

Also remember to bios mod your gpus

30% fan should be enough

Edit: Consider getting vega gpu, they are better on all cryptonight algos.

Not a great idea, you could be expelled.
You want a silent case? Go hydro, I mean liquid cooling.
And if you can shell out the cash then maybe try some Nzxt cases or the Obsidian Series or the deep silence cases. But mind you, they're all pricey.

You'd ideally want to reduce any rattle the moving parts make. DIY solution, loosen the screws & stick a small flat layer of eraser in there and tighten the screws. Instant silence.

What miner are you using with your FPGA?  How many watts does it use?

Nexys video ($490) burns around 15W, makes around $2 per day; Avnet KU040 ($975) board burns around 30W, makes $7-$18/day,  Xilinx VCU1525 & Bittware XUPP3R ($3995-$5895) burn 80-175W and make $25-$120 per day depending on the algorithm.  I programmed the FPGA's myself and forked an open source CPUMiner build and adapted it to communicate with the FPGA's.  I'm planning on releasing the bitstreams in around 4-6 weeks.

Would you please allow PMs from newbies, I have some questions to ask about these FPGAs. You mentioned in one of your posts that you are doing Groestl at 1.95GH/s with a VU9P FPGA, what are you getting for SHA256d?

I modded my profile to allow PM's from newbies.  VU9P does SHA-224/256 at 10GH/s, which is useless for bitcoin but profitable for Bismuth (SHA-224).  Not sure why you would even want to do SHA-256.

Sry I'm a piece of shit ;_;




Holy shit that's nice. Any more tips about that?



NICE bro, that's i wanted to see here, someone with real experience in this.

how's your hash rate and profit?
