[Types of hardware] Litecoin mining - 1st Step

[Hashcesar84]

Recent years show us a "boom" of cryptocurrencies and technologies, during 2014 ASIC came and bitcoin took off to the moon over 1200$(GOX).
What about 2014? I believe that's only the beginning Almost every cryptocurrency's value will increase, next one is Litecoin
2013 has been a good year for litecoins, they start grow nicely over 45$ at first days of December and now around 25$ each, not bad.

Could we expect a suddenly boom of litecoins over 100/200$?..yes of course! this is Time to start mining.

What's best soluction?

What i think is GPU AMD 7990, R7990-6GD5, with motherboard ASRock crafted for mining with 4 entries for GPU; good cooling. Windows 7 e cgminer 3.7.2.

5376 Kh/s in a litecoin "ASIC".

do you have better ideas?

7990's generate a lot of heat. I have 2 in a water-cooled system with 2 480 rads and I still can't max out the hash rate because the temp starts going way up.

maybe with a open and bigger case  and adding some fan you could improve your performance productivity.. how many litecoins are you mining daily?

He's using water cooling and massive radiators.  The thermal density is just too high with those cards (or maybe he has high ambient temps).

he needs more ventilation... and more distance between GPU

Reread....he's WATER COOLING

looks like u cant read ...  ventilation in water ?

I can see this will be a pro thread

More ventilation for your water-cooled cards dammit!!!

I have 3 cards so this is an ASIC!!!

sorry guys I thought it was possible add some ventilation in addition to the cooling system  maybe at the bottom, I'm so noob about cooling systems.

Anyway is it the problem which stops people mining litecoins?

I opened one side of the case to let more heat out and added 4 better 120mm fans to cool the 480 rad on the top. Now I am maxing out the 7990's at 720KHs per gpu core and my temps are 62C to 64C. Much better. From the 2 7990's I am getting about .8 LTC per day. This is my gaming system however so I sometimes do stop mining so that I can play Call of Duty. Before water-cooling my best temps were 89C to 94C.

If you can tolerate the noise from 5 gpu's in a open case I think R9 280's air-cooled would be a better option than 7990's for LTC mining.

I am designing and building custom enclosures for GPU mining

If you have no clue what you're talking about then why are you trying to answer questions on the subject?

I was just giving an advice and if I don't know about cooling system it doesn't mean I can't speak about it, it is a forum where people learn to mine.
I'm an electrician in the refrigeration industries and I think I know what I'm talking about, now I've readen about water cooling system and I know that chips exchange heat directly with the water for the entire surface, anyway 1 fan at the bottom can help to have a change of air.

Which is better for summer running of a small rig farm:

* Portable A/C unit until ambient temps drop
* Fixed A/C unit - residential type
* Rent container with refrigeration built-in - like on the back of a truck for moving meat in cold storage

Refrigeration units generally don't work too well unless they have been specifically designed to work with circuitry. Moisture in the air tends to form frost on the boards, which is not good..

Good point. Was thinking that the heat from the cards and a turned down temp would just give a nice chill on the cheap.
