Main computer mining rig
-
Looking at around 850GBP for the cooling solution.
1x Cooler Master HAF Stacker 935 cabinet
2x HW Labs Black Ice SR1 360 Radiator (should handle 600w each)
6x Noctua NF-F12 PWM 120mm fan
1x Swiftech MCP655 waterpump
1x XSPC Acrylic Dual 5.25" Reservoir for Laing D5
3x EK Waterblocks EK-FC R9-290X
Then 3x 290X == 1200 GBP
So total im in for 2050GBP
Looking at coinwarz i make around 18$ pr day (subtracted the electrisity) it will take 6.5Months to reach ROI, 4,5 if i add an fourth card.
However this ROI could go up and down depending on how smart i mine/sell. Also i then would sell my 7990 which should bring in around 400GBP (its that dry out there, sold my 7970 for 250GBP…)
The difference here is that this will be my gaming rig, and basement “heater”, not like my rigs in the caravan than just heats outside >:D

This sounds like such a fun project. Have you considered Yate Loon for your radiator fans over the Noctua? They are usually much cheaper and similar performance*. Any plans for the loop design?
* It’s been a few years since I last purchased watercooling gear.

No i havent, just looked up Yate loon 120mm, their 1/3 of the price.
Kinda worried about the noice level though, spec says 40DB
I really love those noctua (used em in previouse build, and their wisper silent), but that was the version not meant for radiators.
I need something that runs faster, warms more, and are more silent. Im going crazy sitting next to my 7990 maschine (yes i do NOT turn of mining when sitting there, did it once and it got damn cold!, and no money:P)
-
Think im gonna skip the reservoir, dont see the need for it after looking at this one:
-
Yeah the Yates are something like 1/3 of the price but something like 90% of the same performance. If I remember correctly it’s static pressure you are after for a radiator fan. I’m sure there will be some comprehensive reviews out there comparing the two.

I will google a bit, cause it would be an high powersaver.
85GBP removed just for replacing the reservoir with an T-Line setup (also more space free’d up!)
Would be another 90GBP cost reduction if i went with the Yates instead:)
Any more tips is much appriciated!
Not to sure about if its the best rad (cooling/silence vice the web says yes)
-
I’ve got the 240 ;)
-
Gonna replace with the Yate Loon D12SH-12 120mm fans! huge savings, and ill just throw in an fan controller frontpanel.
That way i can turn it down while gaming/programming etc, and turn it back up when the GPU’s run with load O0

240 what? the radiator?, well whats your take on it?
-
sorry… the 240 version of that radiator. Yeah, it’s served me well, but my loop had nothing on it like you are planning haha
-
A couple of changes so far:
Total now is 732GBP for the cooling solution.
plus an additional 150GBP for the case, and 1200GBP for the GPU’s
Man i need bitcoin value to rise so i can cash out some funds:P
-
3x Sapphire 290X has been ordered :P
Gonna start off just having it on extenders stacked outside the case! cause today morning it was -5 degrees outside and im FREEZING!
Then i can take me some sweet time in regards to setting up watercooling properly
-
I’d like to look at building a main computer miner, my PC just sits there most of theweek. Is it possible to have the mining program work as a screen saver and kick in automatically when idle and suspend on wake? Can mining be paused/suspended easily? I’ll admit, I’m a virgin miner, I know nothing.
-
Im sure you can set up scheduler of some sort in windows for this, never tried it though.
I just shut down cgminer and start it up again when leaving computer.
However my greedy ass has started to let it be on while using it. cause i want ze money.
Gotta say, looked a bit more into the 290X series, its proper redicilouse.
They say you should have an 750W psu, yet they supply only 1x8pin and 1x6 pin power connector for it???
So this card can at max pull up to 300W+ (according to measurements during load), yet it is only supplied with a total of 225w from PSU.
The rest it gets from the mobo. Thats 75W below on ONE card! and thats the max of the mobo without extra power connector for the pci-e
So when i have 3 of these cards, I’m actually maxing the mobo on the first card, since i have an Asus Maximus Xtreme V mobo with 6pin connector for the pci-e i have enough for the second card to.
But still I’m 75W overloading the system? And they call the mobo Quad ready my ass!!!
Proper pissed off, i cancelled my order, but found out thart ALL the other 290X cards on the market has the same config with 8+6pin. so i reordered.
Gonna send Asus an mail about this so i get it black on white that their mobo doesn’t suck.
-
Whaa?
-
Whaa?
What don’t you understand?
I have had several burned mobs and 24 pin contacts due to overdraw of power from the pci-e slots.
Heres what happens (this is caused due to the power supply to the slots that has an overall limitation of 75w gets surppased…):

Its real dirty and actually quite the fire risk. So i find it amazing that AMD sends out an 300W card, but only supply it with connectors able to handle 225w! 75watt short out of the get go!
Not to mention the manufacturers of mobos that claim to have quad gpu support, but yet don’t properly feed the slots with power to handle such an amount of cards!
-
No, that’s what I don’t understand. The logic behind shipping a card that relies on the motherboard so heavily on a motherboard which is Quad ready.

Yup, its freaking impressive. And it goes for ALL the 290X versions, including the “super” models with tri-x fan. for crying out loud my 280X sapphire toxic has dual 8pin, still their 290X version has 6+8
-
Don’t ask me how many ATX plugs I’ve burnt on the mobo because I’ve forgotten to power the GPU’s :-[

Yup, and thats what pisses me off. i know exactly what happens when pushing to much power out of the pci-e slots. and i have had warranty fights before on this matter!
Still the mobo manufacturers state they support 100% quad GPU, and AMD says you need an 750W psu, but still only supply the card with support for 225w (when the card pulls 300+, measured on 290X standard edition!).
Its the end user that gets burned on this, its a big fire hazard! Not to mention how many PSU cables have gotten destroyed, its not easy to get replacement of those 24pins or those 8pin connectors!
Im gonna fire away an mail to my computer part supplier that i bought the mobo from (they denied me the last burned mobo i sent in). Gonna have them give me the thumbs up first. And if they don’t then ill require refund for it, cause its obviously not delivering what it is promising.
Soooo what they are saying is that it will support 4x 290X (since they havent specified GPUs it involves).
That means 4 x 319w, thats 94w pr card, which again is 376w needed to be supplied from the pci-e ports
So if we look at my mobo with supplied 75w connector extra on it, and that those pci-e is specified for total delivery of 75w, so thats 150w in plus.
That just leaves 226w in under demand.
That shit is gonna be in flames in NO time… need to rethink the whole think :(
