Should I quit or keep on fighting?
-
Thanks for the suggestions, guys! :)
The window is already open, but it’s not enough.
I’m not too keen on the oil cooling because of the problems it can give when you need to remove it.
I like the idea about a “rehearsal room”.
I actually put up a bunch of boxes, pillows and a sleeping bag to catch some of the sound, and it helped a bit.I will probably order some heavy, acoustic curtains and see how much they can do :)

[/quote]Wouldn’t it be cheaper to reduce intensity by one and see how the fans behave?
Also I keep my fans relatively silent by allowing a target temp of 78°C, overheat 80°C and cutoff 82°C
I noticed on my card, that the fans are relatively silent, when running below 50% of max speed

[/quote]When I drop them by one, the lose a lot of speed. But actually, it’s not a bad idea. During night, I will drop the intensity to keep my flatmates happy until I find a better solution :)
Thanks! :)

Hi I don’t know a great deal about mining, but you really shouldn’t quit this, you came to mine some crypto and you aren’t just limited to feathercoin, get what you can while the getting is still good. These break even estimates don’t take into account future values of the currency…

In the test is that the vegetable oil is better than mineral oil coolant and air.
As vegetable oil is not derived from petroleum, does not attack the embedding in plastic components and oil components. Then it can be removed more easily the vegetable oil.
The components are not going to ever wear, it is impossible to wear submerged in oil.:)

Also keep in mind, you could always sacrifice some kh/s for undervolting + downclocking + lower noise + lower power consumption.
example: R9 280x’s may run @ ~1.07v 1000mhz/1250mhz with -g 2 -I 13 hashing @ about 680-690kh/s
fanspeed @ 50% temps @ 65-70°C (ambient 20°C);)

^ that is a sound plan

look into that thread, If i remember doing my calculations correctly you should be able to ROI faster optimizing for power due to your crazy $/KWh…
I run 2 settings, the first is an optimized all out setting getting me 740KH/s per 7970 and the second is my quiet power optimized setting 660KH/s that drops temps about 12c. -

That sounds good :)
But doesn’t vegetable oil get bad faster? Well, I will read about it a bit more and consider again :)[quote author=nimmneun link=topic=5844.msg43109#msg43109 date=1386784585]

I’ve been trying to undervolt. It seems that the core voltage is locked on these XFX R7970 cards, so it’s not so easy. The idea is good, but I just haven’t found a way yet.

[/quote]I have been reading and learning from your thread. Very impressive results!
But as mentioned above, undervolting didn’t go so easily for me. In Afterburner, the voltage is locked, so I did a combination of Afterburner and Trixx. After that, the speeds started dropping over time. It’s back to normal now, except it’s hashing somewhat slower than before. Around 667Kh/s per GPU. Anyway, I think I know the process of getting it back up, so I just need the time to do it.
Any clues on how to unlock the voltage clock on those XFX R7970 would be appreciated :)

Well, i stay go ahead and continue. Try explaining the situation to your roommates, and offer them some shares in your already built rig, theyll be interested then and will start to actually take interest in the mining rig instead of blaming you for the noise :p.

I see your point, which S2 Bergen also made earlier in this thread. I’ll see if I can spread the love for mining ;) -

[/quote]yes undervolting will drop temps alot

my rigs actually are serving as my heater in my apartment lol

I know what you mean. The heater in my bedroom is off during the day while my daily PC is mining :P -

This is exactly what i do. Because my wife doesn’t like the fans, personally find it soothing, I work in a server room a lot. Typically run my cards at 75degrees, at 650Kh/s fans at 65 or so. Anything above that and the noise gets excessive for the spouse.
