That is another long debate, same debate about push or pull fans with radiators.

Here is a good read I got from overclock.net that I also believe to be true (but everyone has their own opinion):

"When a fan spins, air passes from behind to the front through the blades. The blades rotate and a pressure differential is generated between areas of the forward facing and backward facing surfaces. Because of this difference, air is thrusted from behind to the front via the blades. Key point is: higher pressure in the back, lower pressure in the front. Air molecules are accelerated from behind.

So, when a fan is used to pull air, its rear is obstructed and it is relatively more difficult to develop a higher pressure zone. To be more precise, it is harder to develop that pressure differential.
Contrarily, if a fan is used to push air, its front is obstructed but its rear is clear. So it can formulate a higher pressure zone relatively more easier."

In other words, what I get from this is that the fans will be able to pull in more air from the outside and force it into the PSU better, versus, the fan trying to pull obstructed air from the inside of the PSU to the outside.

My understandings could be wrong, feel free to enlighten me peoples.

you do know its easier for the fan to suck out air than push air right? reversing the fan prolly wont be good for the psu

TB85 is available on Newegg but limit 1.

Glad I grabbed that TB250 when I did, Newegg is already out of stock of them already.

Does this X370 board run 6 cards? Anyone spot any Ryzen 6/7 PCIe boards that can be used for mining?

much apologies guys, i've been really super busy, replied all pm's & will reply as they come along.

there will be some shipping out today as i promised by today. running all over town to get lots fo stuffs & nego's has been going on.

just got keys to my new dc, workshop, playground, warehouse ... lots of work to do from there on.

some fun pics, yeah i'm here spamming again . . .



1 for me without the 1080 but with 32gb of ddr4 ram



this is really a very BIG GPU



THICK & LONG too

 

cool fan design & HUNGRY for lotsa POWER !



everything seems to be BIG, Long, Thick & huge in AM4 stuffs



it booted up !

SORRY for the spam, i had to build this overnight to get my monster pc up, replaced my 3730k 6 core 2011 rampage 4 extreme.

*OP delete as needed & also please PM me your mailing address*
*philipma, sorry for the dealy, really tied up running around town, stuffs are already in the box*
shipping from me to USA is pretty fast afaik. let's see.

Happy mining to all, most pm's replied.

For anyone that wants a quick fix on the HP server PSU high pitch noise. What I did was reverse the fan, so it pushes air, instead of pulling air. Helped with the noise a lot for me.

Should be good as its' made for mining and same design as the TB85.  Only difference is that it uses LGA 1151 CPU vs 1150 and DDR4 vs DDR3 RAM.  I just ordered 1 to play too.

Does anyone have any information about this board? It looks like a brand new Biostar board for a 6 GPU rig.

I just purchased one for my first rig, so I guess I'll find out how it works.

thanks bud  I wil give you a shipping addy in pm

@ Phillip - A couple of weeks delay due to Tytanick wanting to unload V1 first and V2 of SRR pricing is not confirmed.  Would hate to send you wrong pricing info, I'm antsy waiting for my SRR too.  My guess is I can't place the order until another week or two and arrival ETA is end of April.  PMing you now.  I will send you a nice care package so you can play with Pico and server PSU as it will take a while from Asia.  =)

you have confused me  quite a bit
I thought you were shipping a package of gear to me.

no worries if you changed your mind.




@ yslyung
  

let me know when you get the srr's as I am going to need a setup for 8 pc's



edit I hate the spring  I always mirror image shit.


@ yun9999   let me know when you   have the   srr for me

@ yslyung    let me know when you ship the  gear to me-------   ie breakout board wires and pico

Hey guys, after reading through the entire thread, and been monitoring it for a while, you've made me want to take the jump into a real first rig. I currently run a 3GPU rig in my main computer, just using a whole regular computer setup to power/run it, with an added box fan to cool since it's in a semi closed (1 side panel off) case. I want to make the jump into a full 6 GPU rig, and was wondering if anyone had any suggestions on what to buy. I know GPU's well, so that's not an issue. I searched for all the boards that are in this initial post, and none of them are available for any decent prices anymore. So I'm stuck right at the gate with what motherboard to go with. It would be nice to get some information on a mobo and risers to use, plus a power supply. I see this talk about using a server supply and a pico, but honestly I'm lost with that. My thought would just be a 1200W EVGA platinum for PSU.

So I guess my question is, what mobo + risers do you suggest for a first full rig, and is a 1200W EVGA platinum a good PSU to go with it? I plan to use 6x RX470's for it, with undervolting. Currently I have 2 RX470's both running at about 110W each.

I would also like to build my own open air case for it, does anyone have any suggestions for designs or where to look to go find some?

I love the seeing everyone's builds, and hope I can get one to show off here as well. Thanks for any help guys.

Edit: This is my current board in my regular PC, from my understanding, this thing can run 5 cards with the expresses and risers?

I can offer the free warehousing  and perhaps ship it to 1 person who will handle the group order or something but I don't have the cycles to be mailing things out to each individuals.  I don't even have time to finish building all my rigs here which is an opportunity lost of $15-20 / rig.   It may make more sense for him to partner up with Hawkfish or someone similar for USA distribution as Hawkfish have many sales channel, Amazon, Ebay and direct.  Yeah at $30 / breakout board, the total cost after PSU, Pico, and cables and the value is diminished a bit compared to ATX with the better resell value.  I already have a bunch of these HP PSU and Picos so for me, doesn't really matter.  I just want to use them but I don't want any loud noise.  Those Antminer days are long gone for me.

30 dollars for the breakout board is just a tad over what I would pay for one, then you gotta add shipping from where he is located, if he managed to bring costs down to 20 dollars plus shipping, I would buy from him

@yun9999 will he be shipping any to you for US shipping?

@ Phillip - Seems you're attracted to high pitch PSU noises.  Haha.  YOu will need a breakout board from YSYLUNG to fix that issue.  Don't get the ebay one! 

Okay   @ yun9999  waiting for   the srr when do they come in.

@ yun9999

I pulled trigger on this

looking forward to using your gear with it.

theres nothing to explain as of yet, thats a special setup

!!!! You can explain how you do to have as much gpu?

You have a picture of your installation because 15 gpu I am curious to see how you do.
