Seller refunded 2BTC, due to a mistake on my part. Great service, great person to deal with!

Thank you very much!


Hi,

Yesterday, I forgot to deduct 10% from the gift card value. I will appreciate if you can refund me 2BTC.

Thanks.

They have all sold. Thanks again to my lovely buyers.

I'm doing exactly what you said.
I lost a card a few months ago to condensation. I wasn't home and the Internet went out. The cards got very cold and condensation happened. The lost card was using an XSPC block, all EKs were OK. For this I try to no longer use XSPC, they sure have a condensation problem.

It comes from the river, it goes to the river. I believe is better than to run the air conditioner non-stop.

brilliant idea, really   Roll Eyes

How do you deal with the condensation?  Faucet water is much colder than ambient temps

I am not saying he is doing this but with a heat exchanger you can make the GPU loop any temp you want.  Keep GPU loop's flow fixed and adjust the cold side loop (the cold water -> heat exchanger -> drain) flow so that it pulls enough heat from the hot side (GPU loop) to cool it down but keep it above ambient.

Yes, luckily I have free water.

Yes, I do.

You just run the tap water all the time?  Shocked

I guess you have free (or flat rate) water?

Just cold water. Here is a pic:

Hi,
I have a similar setup, with 12 cards (9 5970 and 4 5870) working flowlessly for about 1 year.  The diferrence is that I ran them in series. I'm using a Koolance heat exchanger connected to the cold water line. Will soon add 5 more cards.


Just to clarify Ciuciu, is your exchanger right b4 the water heater?  (preheating) or you just use cold line to cool the loop?


631  Other / CPU/GPU Bitcoin mining hardware / Re: (Updated w/ pics) Watercooled Rack of Servers - 50% completed on: April 27, 2012, 03:30:09 PM
I use no radiator.

Gotcha.
What do you use for the radiator?


The cards are in series. I have only one heat exchanger.

Running those plate exchangers in series? or the GPU block?

Because the former would ABSOLUTELY kill the pressure. I dont think thats good for the water heater at all.

I'm cheap so i will try to make those exchanger myselft.. Tongue yeah i know. Its the same parallel channels design. But i'm thinking of having at least 5 of them in parallel loops.

Yes, you right. First card is at 20C last at 40C. To lower the temperatures I can increase the cold water debit, but I want to keep the noise down.

Connecting the loops in series would allow higher temps to be dumped into the heat exchager right? The higher delta T the better. But it also means that your rigs run hotter or at least some of them do. Which might create more energy consumption due to the worse switching efficiency of higher temps on GPU.

Yeah, the heat was driving me insane last summer.

Awesome.  First I have heard of anyone else doing this.

Son,

If you look how old my account is you will shut up, which you should do anyway. If somebody is not as chatty as you are, doesn't mean a thing.
There are a number of free escrow services we can use.



No proof pics from someone who just got out of newbie jail... Roll Eyes

Good luck.
638  Economy / Computer hardware / Re: [WTS] GIGABYTE 5870 VIDEO CARD on: April 21, 2012, 11:35:39 PM
It was sold to me as new, but I can't be sure.
All original packaging is included. It is under warranty, until February 2013.

Thanks.

new? used? including all original packing if used? warranty?
