I never heard of this app. Searching the forums brings up zero results (aside from your post). That should be a huge red flag.
I see no source code.
I see no contact info about the developer.

I see no reason anyone would want to run this executable code on their machines.

I voted spend. I try to save a bit, but as with other currencies, I am better at spending than saving .

 I try to fund my bitcoin "farm" expansion solely with bitcoins mining revenue. Electricity cost is not a factor for me, so anything I mine is profit, I spend most of that in acquiring more mining hardware. Started with a single 4870 (yes, ouch), now I have ~2 GH spread over 3 machines with ample empty PCie slots, that I plan to fill in the next months. This way, I cant really lose. If bitcoin value plummets, I still have hardware thats worth something. If it explodes, Ill be able to generate some actual revenue until difficulty catches up, and some coins saving.

Lol, talking about low expectations.
My HTPC runs ubuntu. I just checked the uptime.


So it has been 7+ months since the housekeeper pulled the power cord or I updated the kernel. In the 3 years Ive used it, unplanned reboots: zero.

No. Though I see no reason it wouldnt work, Id still be dumping the heat in the shed where I dont want it, and not in the water where at least it has some uses. Also I dont have a spare fridge and its very bulky and probably beyond my skills.


I would pump the oil with a ... pump . You could use most water pumps, if it can pump water, it can pump light oil. A large aquarium pump might do the job, but overheating is something to pay attention to. I dont know how hot the oil will end up being, but assuming 50+C, thats not something all pumps will like. So , Im looking at this pump:

http://www.ebay.co.uk/itm/High-temperature-100C-Water-Oil-Pump-w-speed-Control-/160526138814

As for the number of GPU's; I only have 5 atm, but I plan on expanding that in the coming months. Im waiting for HD 7xxx0 cards to go mainstream and hoping 5xxx cards will become cheap secondhand.  But for now, I started work on a small bath that will hold 4 or 5 gpus max. Depending on temps I get, I might scale that up, possible by "daisy chaining" several oil baths using the same single pump and radiator or add more if need be.

But I actually suspect the above pump combined with a car or motorcycle oil radiator will be overkill for 10 cards, it might handle 100+ cards. After all, the oil radiator on my bike is no bigger, its only air cooled and my bike produces 80+ KW of power. Granted not all of that heat is dumped in the oil, but much of it is.

But Ill only know for sure when I have tried.


Its a concern yes, certainly if I wanted to use pure mineral oil. All I have found here is hideously expensive. If you live in the US, this would seem good and cheap:

http://www.amazon.com/Durvet-Mineral-Oil-1-Gal/dp/B000HHLUE6

Ive not found anything remotely that cheap here.

For vegetable oil, its not much of a concern, its really cheap, though it will also depends how long it will last before it needs replacement. If it ever needs replacement, who knows? I dont .

 Since the amount of oil would have no real impact on the temperature theoretically, I plan on minimizing the amount. Currently working on a small 25L prototype. When my extender cables and a spare motherboard+cpu combo arrive I will plunge in a single old nvidia card with no oil cooling just to see what happens. If it doesnt overheat with just a single ~100W, I may even keep that running for a few months  to see how the videocard, fans and the oil cope.


Pumping dirty pond water with leaves, needles, fish poop, gunk, algae and what have you through a radiator is asking for trouble. Its gonna clog in a matter of days, at most weeks. I see what happens in my filters, its not pretty.  

Nothing against cablesaurus, but the extenders they sell are the exact same one's you can get on ebay... for a fair bit cheaper.

Good to hear the pool operator wants to know what the miners think. I suspect thats more than what Luke did before casting his (miners') vote(s).

That said, I have no real opinion on the subject. I got no clue what its about. Maybe if someone could give me an executive summary I might form an opinion, but absent that, my second instinct is to trust Gavin above Luke.

And I disagree on all accounts. I disagree "instability" plays a role (*). I disagree that they will have a bomb; even US intelligence agencies say they are not working on one. I disagree they could not be stopped if ever they changed their mind, which they can not do in secret.  And Im not even sure if somehow they got nukes, it would be so terrible. Not when North Korea, Israel and particularly Pakistan and India have them. Iranian Mullahs may be religious nuts, they are neither suicidal nor genocidal. They would have absolutely no reason to use them first. None. I would worry more about the Israeli arsenal.

(*) if anything all the warmongering, sanctions and threats -not too mention, terrorist attacks inside Iran-  to counter a non-existent nuclear weapon program are causing instability and inciting Iran to develop nukes if for no other reason as M.A.D. self defense. If you really dont want Iran to have nukes, then keep them in the NPT, rather than deny them what they are explicitly entitled to within the NPT and at the same time give them every reason to leave the NPT. A 6 year old could understand that, clearly the issue isnt iranian nukes.

Lol. I might try that, if there were any side panels. Or top or bottom

Thats the most ridiculous definition of unstable I ever heard. By your logic, China is extremely unstable, Saudi Arabia is one of the least stable countries in the world, while Pakistan would be fairly stable.
really 

BTW,  I think you are wrong about the level of resistance against the Iranian regime. Its not the most popular government in the world, but certainly not the most hated either. Its far more popular than the Saudi or Bahreini dictatorships for sure.


Unstable to me, means risk of violent conflict. Absent a military action by the US or Israel, I see no such threat whatsoever. Iran is at peace with its neighbors and has been for decades (aside from Iraq, thats fairly recent). The only thing that really makes the region so unstable is US and Israel.


You tell me, you brought up stability up as a reason somehow for denying Iran their sovereign rights?

8 BTC sent for 6 cables. Will report when I receive them.

Oh. So that makes Saudi Arabia, Bahrein,  Russia, China and a gazillion other countries also "unstable" then?
I never said Iran was a model democracy. Even though it actually is compared to most US allies in the region, but it isnt by any sensible definition. What does that have to do with stability, or for that matter, this topic?

What is unstable about Iran? Its been the same regime for 30+ years. The only war it has been involved in, has been a defensive one against a US sponsored invasion by Iraq. There are some protest, but quite frankly, possibly less so then there are in the US. Whats unstable about Iran? Its not because the US tries everything it can to destabilize the regime that its working. It isnt.

You have PM

You said "the US thinks..". Have any evidence that US wants Israel to dismantle its nuclear arsenal?

I just did a small test, mixing vegetable oil with light paraffin oil; the parafin oil does float on top, but if you stir the fluids thoroughly, it seems to mix. An hour later I cant really say I see a layer of parafin oil floating on top. Bummer .

Oh it seems the entire poll is actually linked at the bottom of the website I linked. I highly recommend everyone to look at it, it may help many of you to better understand Arab sentiment.

Anyway, here is one I was referring to, and that should catch your eye when you call Iran an international pariah; while their puppet regimes may tell you differently, arabs themselves disagree:

I see no reason why that wouldnt work, but boy, sure sounds a lot more complicated than buying a $40 oil cooler. In either scenario you still need tubing, a pump, oil container etc. It would also take up even more space in my shed for no apparent advantage. Perhaps if you have a water source and no filter or pumps to use, then your approach might make sense, though Id probably still prefer to just put the radiator straight in the pond or swimming pool or whatever.

Also dont underestimate how difficult it is to make a pressurized vessel of any kind. Ive had a smallish commercial pressure filter once, with a 19mm in and outlet.
when I accidentally hooked up the wrong (too powerful) pump, it exploded. Water pressure is nasty.

So you think its a better idea to allow only one nation to ignore non proliferation treaties, have nukes and threaten its neighbors with it? Not just any nation, one of the only remaining apartheid regimes, a terrorist sponsoring state ran by warmongering crackpots that actually are crazy enough to use it offensively.

I saw a poll a while ago held in the middle east region about the issue. Almost no one there considers Iran a threat to stability or peace, quite on the contrary. Overwhelmingly they see Israel and the US as a threat to peace and stability. When asked if they would consider the region more or less dangerous if Iran acquired nukes, the majority now say it would be positive, even in Sunni states, go figure. Here, I only found these key findings:

They have been stopped from developing nukes, if ever they did, nearly a decade ago.  Why doesnt anyone listen to US intelligence agencies when they say something diametrically opposite of warmongering and lying politicians and media? Go read the national intelligence estimate.

Its no different than with a submerged radiator. Assuming your ammo box has equal thermal transfer characteristics as an oil cooler, which I doubt considering the thickness, coating etc, all that matter is surface area and temperature difference between the liquids.  A radiator has a huge surface area for its volume, while with your approach, surface area is directly linked to the amount of oil and scales rather poorly with it (cubic root) .

Mind you, Im not saying it wouldnt be enough but I fail to see the advantage, particularly since I wouldnt be able to flow nearly as much water through the "containing container", so Id have higher water temps (and evaporation).  The rigs will be above pond water level, so I cant use gravity feed, I need pump fed. Since you cant pressurize the container, you need gravity return. Unless I plumb at the very least 50mm water return pipes to the shed, thats going to be a serious limitation on flow rate or cause headaches with the water level. To give you an idea, I use 130mm return pipes in my filter, and with my pump capacity even that creates a 10+cm increase in water levels in the filters. Now I dont think youd need anything like the kind of waterflow I have through the filters, but it sure doesnt hurt, and I already have it, so why not use it? The higher the flow, the lower the water temps.


Not sure what you mean by protect. Protect from what? Take a motherboard with a few gpu's (probably using extender cables), turn it upside down. Drop the cards in an oil bath. Even if oil would splash on the MB or PSUs or, or the oil creeps up, it doesnt matter. Ill probably prevent this by creating a lid over the oil box though, mostly to prevent dirt from getting in.  I will wire the cables through the lid and seal it (and may use PCIe power extender cables that are fixed in the lid, so the psu cables plug in to the lid), but thats not even necessary.


Here is sketch made by the 5 year old in me to explain :
