Oh my god, you seriously cannot begin to understand how happy finding this thread has made me.
I CAN TURN THE FANS Down (sshhh) I have had 2 L3+'s (and an S9 - but that HAD to be forced elsewhere) literally 15 feet from my head 24/7 - it was like someone feeding a sentiant AI into a digital mincer. It has almost been worth the chronic migraines and liver failure (due to quantities of paracetamol for debilitating headaches) just to lay down here with the fans at 30%. You know like having to go after a realllyyy long bus journey.
God bless however mentioned that the fans could be adjusted. As you may of guessed this is my first venture into mining and I nearly sold them for real cheap today (or was going to spend $600 on custom sound deadening cases).
so from 4720 rpm stock to 3480. Amazing. Dropped the frequency (Kenneth) down to 350 to be on the safe side, highest chip temp is 54c after 90min. I think I can put it up a little but will hold on another couple of hours. The S9 chips are up around 80c afair, but not sure if I'm comparing apples with apples.
Few things I've noticed - most intresting first, see Bitmain have launched a whole A.I division... I didn't really give much though to the S9's chips being 16 nanometers, until I googled what a nanometer was - a human hair is 80,000 - 100,000 nano meters! How the hell do they make something that switches 1&0's only 16 nanometers??! I can't imagine. I can't imagine it being done without Chinese state assistance. No ICO's, No Exchanges, but max out the mining and spin off A.I tech... conspiracy theory Thursday. Surely creating a wee machine 16nanometers for mass production is pretty astonishing? I think so, but then I have just figured out how to turn the fans down after nearly 2 months so perhaps I'm not fronting the bell curve.
A lot of people holding major beef against Bitmain. I don't know why really. The only thing they have done on me (which is really sloppy actually) they labeled my most recent L3+ as 1640 - no currency symbol. And it cost 1540 odd. So being UK I got hit with customs in £'s or GBP, which ran me an extra $150 import tax.
I am yet to get my 4th and final miner (S9 - 2xL3+ 2XS9) between 10-19th Jan, so won't praise them to quickly (esp after something so stupid as misspricing without a currency symbol - I will try and claim it back, but it won't be fun). But in fairness the 3 have arrived working, when they said. I'm not sure Bitmain can be held responsible for the pretty disappointing returns I'm getting on Pro-Hashing - 2 both at 419mh only made $32.98 lnite.
I'm having a real problem on Prohashing with my average miner effeciency, mid 90's, low as 88%. Currently 97.56%.
I wonder is it because I'm getting paid out in 4 diff coins (LTC, GULDEN, ZCASH, VERT) or because I'm runnin 2 L3+'s of a 20 PCI, 1600w Bitmain APW+++? 240v at the wall here, no wattage meters, but maybe my slight overclock pushed them over the 1600w's? If so would you recommend picking up a 3/400w PSU to power a hashing board or 2?
Even so, my prohashing figures are way below nicehashes daily projections. Tip for Chris? Yes. Make your site give me more coin please or I'm off. Are others getting better numbers?
Read about this Miningrigrentals. Sounds great if it's legit. Many here using it? Seems pretty new. But minimum regular payouts could well make it worth the nicehack risk if it is paying out even 15% more.
Beyond that hello
Thank you so so much for saying about the fan thing. I was nanometers from selling the pair below cost today.
All the best
