So friedcat finally came through with the original heatsink. Noticed that the PCB was discolored under the BE 100 chip. This thing is definitely too hot with the new heatsink, even with active cooling I would say. Now with dual proper heatsinks, we'll see how it goes.

Cool, is there a picture of it somewhere? Got a link?

There was photos of the old heatsink, but friedcat removed them. Maybe someone else has posted them?

Can anyone confirm that the PCB gets discolored by the heat with new heatsink and active cooling too?

If you make another GB at 0.99 BTC make sure you ask for the old heatsinks!

HW/A 0.2% so far!

Ein GB wird nicht mehr benötigt werden.
Die Miner werden in De auf Lager sein.
Direkter Versand, keine Mindestbestellmenge

Das ganze Projekt ist schon in trockenen Tüchern aber es ist eben noch nicht alles endgültig geklärt.
Die Tatsache ist friedcat auch bewußt. Deshalb war ich über das gestrige update auch erstaunt.
Hab auch erst davon erfahren also meine PN box geflutet wurde....

-----------------------

you can buy directly, no GB, no minimum
they will be in stock within the EU.
shipping will be from Germany with DHL
oder registered priority mail

But friedcats update was a little bit surprising for me.
Because there are still a few things to clarify.
Must first talk to him and my business partner
so pls give me a few days, thx

--------------------

@rupy
can you take a pic from the discolored PCB?
0.2% is really good, at what timeframe/accepted shares?

@btctr4d3r
I will replace your miners, but please use another hub this time  Wink

Thank you yxt!  Cheesy

Can you guys please help me find a decent USB Hub with EU power plug to order? Had a really bad experience with the last one I bought.

@yxt   bei wem auf Lager? Bei dir?

Der Preis/Unit dürfte ja nicht mehr als 1,1BTC sein incl. Versand nach Dtl. & Handlingfee.  Sehe ich das richtig?

Nein siehst du leider nicht.
der Zoll will schonmal 19% Einfuhrumsatzsteuer 0.99 -> 1.18 BTC + yxts Marge (die muss er auch mit 19%) versteuern und dann noch der Versand.

yeah not so easy also blew up a powerplug of one hub.

good working for me:
logilink 10 Port Hub with 3.5A powerplug feeded with 6 USB eruptors each.
14 Euro on ebay inkl. shipping


there are some hubs locking the same on ebay but there is one Problem plug is only 2.5A (and not a good one!)
be carefull!

Ich denke nicht, dass da noch die Einfuhrsteuer dazu kommt, da die Dinger ja bereits hier in Deutschland auf Lager sind.

Ich bin mal gespannt auf den Endpreis, aber ich glaube nicht, dass es mehr als 1.1 BTC pro Stick wird.

That one looks exactly like the one I had and fried 3 USB eruptor's, but mine had no brand.

Searching in eBay there is not many options with EU power plug :S

I use a 7 port logiLink hub, but only with 6 miners and downlink to another hub.
With 7, two are to close for my preference. 3,5A PS with EU plug.

can post a pic today or tomorrow.

--------

Irgendwie müssen die ja in die EU kommen, den Zeitaufwand hatte ich bei dem GB unterschätzt, ist doch einiges an Arbeit.

Preise stehen noch nicht fest. Aber wir werden versuchen die Preise vom Kanadischen Reseller mitzugehen.

3a powerplug each - should be fine with 5 in it

for D-Link I think the plug is doing what they pretend to
soyntec - don't know this company.

I think yxts 7-Port Logilink has the same plug as my 10 port version...

this is mine:

maybe yxts:

HW/A is 0.3% with old heatsink. I think we have a real problem! You guys should REALLY care, your investment is burning up!

0,3% is good also, up to the 1% range is ok

I talked a few times with friedcat about the heat.
He is sure they can handle it.
But as i wrote here a few times I recommend cooling..

Can you please take a picture from the discolored PCB?

yxt, ich habe hier drei defekte USB-Erupters... trotz externer Kühlung (USB-Ventilatoren je 5 Sticks 1 Ventilator, das Setup 7x)
Wie soll denn die Garantieabwicklung aussehen ? Denke Du hast den direkteren Draht zu Friedcat.... ;(

Falls sie von mir sind sende sie zurück und du bekommst neue (schreib mir davor aber bitte eine PN),
ansonsten muss man mal schauen

Ist bei dir auch etwas verfärbt?

Can you take a picture of one of yours instead? There is going to be alot of hard words on the forum if these start to fail because of bad heatsink design. The problem is my chip had 0,9% HW/A witout HS, I'm pretty sure that would be higher if I add that new flat HS.

Edit: maybe it was premature, the HW/A is now up to 0.5%...

Still can someone look at their PCB?

I'm temporarily putting a fan on mine just to try and prove my case.

Ok, nm, still climbing, with fan, and two heatsinks... there seems to be no correlation between heat and HW?!
