I think that's Tarkins site but he may be on vacation still

Hey BE CAREFUL OUT THERE.  I'm calling a scam alert until I hear otherwise from GenTarkin himself.  I assume if he had put up this website and it was legit, he would have told us about it.

It looks like someone over on LiteCoinTalk paid money to this site and hasn't gotten anything in return, so unless GenTarkin tells us it's legit... scam alert.  Spread the word. 

PM with link ?

I'm selling a batch 2 never used titan miner on eBay if you guys are interested.

yeah it helps

the hottest it got here last year was 105f and tarkins mod throttled it down for a few hours

The fan guards are  rusting, which is what got me looking for a solution and I found the conformal coatings. To be honest the boards look fine, just dirty. I guess I'll take them apart, clean em with alcohol, blow them out, and take it from there

I already bought the stuff, maybe I'll do one cube -- see if any adverse effects.

here's what I got http://www.amazon.com/gp/product/B008O9YGQI?psc=1&redirect=true&ref_=oh_aui_search_detailpage

and http://www.amazon.com/gp/product/B005DNQX3C?psc=1&redirect=true&ref_=oh_aui_detailpage_o04_s01

thx

Hrm. Conformal coating does keep out the crud but does keep in the heat; I can see a 20c difference between having a thin layer of conformal coating on the water block to Neptune chip interface, sanding it off really dropped the temps.

Honestly though I don't think environment is that massive a deal with these kinds of units. Unless you're really running it in a dirt farm, or got the thing submerged in crummy water it shouldn't be that terrible. I had some thoughts on pictures of another company's miner that was refused RMA due to "environment damage" and thought "that's not unusual". Besides if it's a really corrosive atmosphere the fan will probably seize first, which will overtemp the device.*

A properly conformal coated board though can take a lot of environmental damage: I once fixed an electric car controller that had a leak from the water plate inside the controller box. Literally covered everything with oily, antifreeze laden gunk. Cleaned the boards, cleared out the fault maker (the pre-charge relay) and the board fired right up with no problems.

However in that case you have 400 volt DC lines on the board, and that kind of voltage will bridge gaps caused by gunk. 12 volts? Not so much.... .6 volts? Really not so much.

What do I use for home electronic repairs? TechSpral Fine-L-Kote SR silicon conformal coating spray. Light coat is all you really need.

Hope this helps.

* Then again I saw discussions about another that had been rne in in a closed room in a 110+ degree day in the Australian outback and they were complaining that it was throttling. No AC no nothing. Um.... that's what is called "way outside parameters". Too many manufacturers build for a 68 degree data center, which is not what the typical home has (there is a big difference between how much heat a radiator can dissipate between 70f and 80f)

Lightfoot, any thoughts on applying a conformal coating to the titan PCB?

I run mine in unconditioned space and I am near salt water, do you think it is a good idea to apply in this situation?

risk vs reward, some loss of heat transfer vs protecting circuit from the environment -- I won't be applying it to any heatsinks, just the pcb -- I know from soldering this board that it is pretty tough, maybe conformal isn't necessary, ie a lot of work for minimal reward -- what do you think?

Yes, that is it. It's actually a pretty busy little bee all things considered.


They are very similar boards, so what works on one should work on the other. Just sanded down and re-mounted the water cooler block, it's holding a nice 44c, which is actually 56c as read from the bottom of the board. Top temp on the bottom of the board is 68c under some of the DC-DC supplies, they do dump a lot of heat into the board planes.....

just to make sure the FPGA chip is the 'frigging' big chip on the Titan board right? (likely but not like they are labeled)





(the large chip ..square...on the right side of the pic above.....I assume that it is not a 'hidden' chip under the pi controller and daughter board....)


er make sure the 'water cooled' neptune project also works with Titans...you'd get more action out of the expense of making a Titan water cooled then a Neptune at this point in time..just saying

Thanks! Hm. This one is running at 50c, which is actually quite warm. Maybe ones that blow up run hot, I'll have to wait till I get another one.

In the meantime I now know what blows up Neptunes and probably titans (Note: NEVER move a hot or running unit, let them cool first) and can fix blown Neptune boards that don't talk back to the controller. It's a bit of a bitch to do, but for a blown Titan it's probably well worth it.

Now back to working on the water cooled Neptune. Having conformal coating on my water blocks (used to mount them on backs of boards) is cutting the efficiency. Likewise the chips run hotter than the temp sensors say, watch out....

Well I 'fondled' my Titan fpga chip as you asked in the above post. (I feel dirty)

It is cool to the touch...no real heat at all on this chip. This is true of BOTH my Titans.

So I guess 'neutral heat" is what I'd say neither hot nor cold and barely warm at that

imho it is Innsilicon out of china...making a push at scrypt data halls *just a guess I've no real clue*

(that or knc has made an 'evil' titan data hall or two..and is not saying...hey I really, really hate those guys ...everyone is entitled to "one' zonky

conspiracy theory ..don't ha know

Which

Company put

Sooooo
Much

Power

At litecoin diff

I knew it would come to this.....folk on the thread have now resorted talking others into 'fondling' their KNC Equipment..(hey what you do in privacy with your  titan miner is your business.....but really...to post such asic porn crimes in public!) ...I suppose soon the 'compromising photo's will surface" ..alas .the shame and horror..this thread is 'doomed'




hubba, hubba

Quick question for anyone listening: Can you touch with your finger the FPGA chip on a running Neptune/Titan controller board and tell me if it's cold or warm? If warm, how warm?

Thanks and happy holidays!

you mean 'clone' the bottom 6 port Titan Card? is that even 'doable?' (also epic if possible)

me...as far as projects ..got the thermal paste/heatsinks (self-stick) and the better fan (swedish guy titan fix video on this thread) soooooo....now just have to 'man up' and take the cube apart i suspect is slowly losing it due to heat....was all at 325 setting on adv page now only 2 dies..other 2 are 250 and 275 respectively....i try to up them heat shoots up above 95c (ie a 'clue' to repaste I think)

projects, projects and never any time

again any titan owners in midwest usa with xcel energy look on the back of your bill for discounted elec for home heat with electric to save some cash (115 a month saved by me for 5 months...) check my pm's under my name or look back on this thread (don't want to go too off topic) but very very happy fellow I am tripping over such..i would ASSUME that other elec utils offer such on winter heat look and ask around imho

Haha, well i've got plenty of titan LCDs, don't really need them anyway.

But yeah if anyone's willing to send a neptune/sha256 knc board my way I can risk my pi and bridge to see if the controller is basic or complex. In the case of it being complex i'll just clone it as a last resort.

you need me to send a spare Titan LCD or not in issue you can pop yours off? I also have a raspberry pi B+ 512mb 'supposedly' the version you are supposed to use (according to a knc tech on knc forums back in the day ..for what it is worth)

you do realize you will be a 'god' on this thread if you pull this off right? (many bridges sold...so many bridges....ie example..was told on this thread many times I could take my KNC OCT Jupiter (or saturn/mercury) or NOV Jupiter and UPGRADE them to a Neptune...thus the only thing I need is a frigging bridge and a pi and viola I have a spare TITAN controller (or if you have a trashed Titan controller you now have some hope)..my god 'recycling' old Jupiter boards even a 4 port board like mine to a Titan board would be frigging epic!

me ...I'd like the 3rd controller just to use for 'a couple' problem cubes I have to play with off by themselves w/o mucking up the other systems..I could
reboot away and dork with them some w/o taking down or power flipping a hole 'titan' unit as such (or offline)

anyway it likely won't work ..but maybe if it DON'T blow up....could give the coders a clue on wtf is going on for maybe a future fix?

(ah stuff to break ...i like it...would be much better with 3 of us and a few beers for courage thou...just saying)

Hey, I can take a hint. :|

lol I'm all for the idea, I have an extra pi and am willing to use a bridge up on a neptune for trials if someone is willing to send me their working neptune controller board (even though it most likely won't work, but we can't confirm either way until we try it).

we need someone brave (hint) with many titan bridges (double hint) to track down a Neptune board (most likely to work) and I can contribute the PI (too lame to use my 1 bridge) and  just see if one of these W/O A TITAN CUBE will not sit and act proper under the KNC Tarky Titan GUI etc (i can also toss in an unused Titan LCD to see if that comes up AGAIN WITH NO CUBE with nice tarky titan info)

at that point we can double dare each other for a few weeks to donate a Titan cube (even with only 1 die working) to test this completely

or am I simply in OZ with the rainbows and unicorns and someone braver then myself has tried this already with a big fat 'don't work'

I probably would man up and try it with my OCT Jupiter board that supposedly you can upgrade to a Neptune board..but we'd be better off on the
above test with a Neptune board imho

(why do i get the sense I'm going to hear the sound of crickets..on this idea....'deafening silence is my likely result to this post)
