Is that your bed next to an SP20 & a S5? Do you sleep with industrial ear muffs strapped to your head? 
That is dedication. Definitely could keep a eye on it that way though. I personally keep them out of bedrooms
You stop being able to hear it after a while, its surprising what level of noise can become the baseline. Its also a lot easier because miner noise is perfectly level.
improving your mining power by up to 15% by simply running an additional script and light weight software package
That's a pretty bold claim right there. So a stock S5 will get 1328Gh by a script?
Overclocked yes. Im running poolside averages of 1280-1320ish on the units.
Whenever you post your next resource, please make it exceptionally clear that overclocking will void a user's warranty.
As far as I can tell - Overclocking DOES NOT void the warranty. There is no statement on the website - unless I am blind (possible) - and all the manual states regarding the OC/Frequency is:
4.2 Frequency Modification
You are able to modify the frequency value through ‘Miner Configuration->Advanced Settings‘.
The default frequency for the AntMiner S5 is 350M.
No where does it state that by going above default voids the warranty. I would think from a legal standpoint that denying a client RMA because he/she OC'd the unit has no legal justification - and certainly can't be imposed retroactively.
Perhaps Bitmain should add that to it's site or manuals - for new orders of course.
