Hello gentarkin!I think your idea of fan fail message on the lcd screen is a good idea because i use lcd screen.But i have a question :Is there a possibility to change the way that the cubes are detected by the controller?I still have problem with my titan who isn't working anymore since 2 months now just because cubes are not detected anymore.on the four cubes ,just one recognized by the controller in the dcdc's average temperature  column but not in the temperature column of the status page.i can't fix the problem and have no idea anymore....

I LOVE IT!!!!!!!!!!!!!!!!!!!

Hello vegas and thanks for your quick answer...i will try this evening what you write in your last post and PM you the results.thanks again.

I think this is a good addition to notify of fan failure and in my case of unattended miners its great to have over heat protections built in

Gentarkin and I have talked and decided to focus more heavily on developing the premium version. The free version will always be atleast 1 version behind from now on. The premium version users will always get the latest version , the minute its released. V.99b will be released very shortly to the premium users. My website is in the middle of changing host providers, so its down for a few hours. When v.99b is released I will post it on my premium page and email everyone that has paid for a premium version.

V.99b will include the following changes and will be released soon:

Major changes in this release:
FAN-FAIL protection - The way this works is, if any die DCDC's are detected 10C over the user specified temp threshold(and DCDC protection is enabled) OR DCDC's are over 115C(and DCDC protection is enabled) then those dies will be shut off & bfgminer restarted. A warning in big red letters will be thrown up on the STATUS page of webgui, also if using the LCD, its message will switch to "Poss. Fan-Fail!". Both the STATUS page message & LCD message will say what cube(as labeled per webgui advanced page) was flagged as having a possible fan failure.
To clear fan-fail message on status page & LCD... a reboot of the pi will be needed.

there is no way to physically detect an actual fan failure as it seems there is no sort of fan monitoring control on these boards, so thats why I came up w/ the rule based fan failure detection.

Minor changes:
1. More options in DCDC dropdown menu
2. Added wall watts estimation to ADVANCED page. Assumes 85% PSU effeciency plus power required for pi, controllerboard & fans.
3. Replaced default KNC version message on LCD w/ GenTarkin's Mod version information

Minor fixes:
1. Refined hostname(minername) handling & backupname file handling
2. Removed bfgminer.sh from git & builds to avoid overwriting peoples custom command line arguments for bfgminer.

Thank you. We were dividing our time on both and less was getting done. We had to come to a decision on what to do. People still will have a free version, but it will take a backseat, and the premium version with all the latest goodies will come first.

Just want to thank you and Gentarkin for continuing to improve this mod!  I have installed the latest premium V.99b to all 3 Titan Controllers and they are all running well so far.  I do noticed a bit more hashrate fluctuation, but that's probably expected since it has been hot where I am at and the new software is doing a better job of keeping the cubes at a safe temperature.

May I make a suggest for the next firmware release?  How about adding some kind of scheduler to turn off bfgminer/mining at certain configurable hours, when it is hot or when the electricity rate is at the highest during peak hours?  This is more for future consideration if Litecoin difficulty continues to rise faster than the norm.  We can turn off mining when it is unprofitable and turn it back on when it is profitable.

Im happy your happy w/ the firmware! Thanks for your purchase!
Im already testing code for the next release of v.99c =)

Regarding ur suggestions:

Thats quite easy to do, power off the rig... LOL =P

No, but seriously... my code already has temperature adjustment built in, hence the DCDC threshold setting. It will autoclock up down for you =)
A schedule of turning off & on is really not needed. I used to think I could outsmart elec company by mining during offpeak hours and not much at all during peak hours. In the end all calculations came out extremely close.... so really, thats kinda pointless.

Ive had several requests for scheduling features or clock settings scheduling based on expected temps. It takes way more work to impliment then I think is worth it. I think may people forget that the temperature based clock is already built in, and the other folk dont really think about what they are asking .... in the end its like asking someone to reinvent the wheel.

I do appreciate the suggestions tho =)

Just a heads up to all who use my firmware:

Next release is already planned and in testing...
New features:
1. implimented KNCminion webgui interface extension w/ link on status page
2. Auto bypassing of dies that cause soft hard reset spamming
   *note: once a die is added to the list for auto bypass that means its "health" will no longer be monitored. MEANING... no further attempts to reset it will be made if it stops hashing.
   *note: when a die makes it on the auto bypass list a message will appear in webgui ADVANCED page showing you which die and offer an option to clear all the dies in that list.
   *note: when issuing the clear command, those dies very well may make it in that list again, the clear is mostly designed for those who swap around cubes on their controllers.
 
3. other misc fixes n stuff =P

What if I just set it to enable this by default rather than an option? Would that be a problem?
