I wouldn't remove the bottom metal stand - it keeps the boards firmly in place. Thinking about changing the stock fan though, the noise is driving me crazy now with 4 units

The stock fan is very noisy, any 7 blade delta fan is better. If they could just change the fan connector to standard PC PWM socket, it will be much easier to mod

The metal stand below the fan can be removed, it contact directly with the fan and amplify its noise

Regarding 2.6.1 firmware...
CGMiner reports greatly exaggerated hashrate results....
For example, the last 3 days, cgminer shows an average of 1770GH, while the miner is 1432GH in 'asic stats' page and pool reflects just 1430GH's as well....

This wasnt a problem w/ previous firmware / old cgminer 4.7.0 version...

Fan:
However as its a propietary connector to the daughterboard in the SP20, you either have to cut the connector off the stock fan and wire it up to the new one, or you have to connect it to the PSU directly

sure, it is proprietary? What's the name of that even smaller kind of connector?


it may be a vga type but I have seen  more then one of them.

Anybody knows what kind of fan Sp20 has? 38mmX120X120mm or something else? I can look up myself, of course, but don't want to stop the hashing.
Thinking of putting either delta or Scythe ultra kaze in place of the stock fan; i know someone even put gentle typhoon, but i need to support just 1200gh/600-650w.

>snip image<

I've used a Scythe ultra kaze but they are only 130CFM which is fine if you are underclocking.

Any of the Scythe high CFM fans will work, the black high speed GT's or the even scythe kaze jyuni 1900rpm

But yes its a 38x120mm fan but you can use a 25mm fan if you want.

I've currently got the Ultra Kaze on one of my SP20's

However as its a propietary connector to the daughterboard in the SP20, you either have to cut the connector off the stock fan and wire it up to the new one, or you have to connect it to the PSU directly like I did:

Thanks. Did it help? I am not sure what % of the sound (72db at fan 20 for the stock fan) is caused by the fan itself and how much is caused by moving the air through the metallic grille/sieve. The stock fan is supposed to be just 61dB, but SP20 produces way more than that (up to 72dB close by).

Yes it helped, the fan itself or rather the bearings are what make the metallic noise the stock fan makes. A kaze ultra at 100% is much more bearable.

I'm seriously considering dremeling that out and taking a new measurement.

I have considered making the holes bigger with a drill bit.  I am going to wait until the oldest one is past warranty.  What is warranty 90 days?

I could have sworn it was a 30 day warranty, but I'm having trouble finding that on their site.  We may need to ask in the official thread.

I recall it being a 90 day warranty..

Right.  I added westhash (as I'm in the US) as my first pool, and add a high price per TH in my password so I don't miss opportunities to mine at a higher market rate.  This way when crazy things like Payoin come along and boost the market price to 500+% your miner switches automatically, even if you are asleep!

My regular primary pool goes in the second pool slot, and is used until my price threshold is exceeded at westhash.

I hope this helps!

yeah, i had that, but then miner periodically connected to westhash even when it was in third position (maybe it was on S5, not Sp20) and the whole setup got frozen once every 24 hr for some reason. Once i removed the westhash, everything was back to normal. Maybe just a coincidence.

I can't speak to the S5, but I've not had any issues with running WH as the first pool on my SP20.  I've been running it with that setup for a couple weeks now.

I normally mine at BTC Guild, however the payment system doesn't work too well if switching from time to time, curious as to you other pool?

Stopped mining at BTC Guild for long. Was thinking of giving it a try again. May I know what is wrong with their payment system now ?

Guild is a great pool, however it's PPLNS shift system encourages regular mining without swapping pools.. I was wondering if someone who used Westhash and a backup had a better option..

put nicehash first on your list   use a high price in the password spot on your  pool section

use p=0.0199  you will only run  if price is over 0.0199    that is a very good price to mine at if price is lower you drop to your second choice on your pool list.

you could use this one for second:

https://www.f2pool.com/   this is paying 0.01097974 BTC / Thash/s  that is about  0.2194 a day for 20 th

or use my favorite :

https://mining.bitcoinaffiliatenetwork.com/index.php    this pays more then any other pool but can be slow to pay.
