just thought id pop this on here to give you all a little laugh..

decided to change the cooler on the 2pac. (yes, i know warranty goes out the window lol)

got an old heatpipe cooler from an old socket7 AMD CPU, drilled the mounting holes into the baseplate, and popped it on with some liquid metal thermal paste. seems to work a treat Wink

GOOD CRAFTSMANSHIP--

How hard can you drive the 2PAC now?  I'd be interested in the specs.  Did you use the stock screws?

I have plenty of oversized CPU coolers, and I just bought a Peltier kit on a whim.  Peltier kits were a big deal (for CPU cooling) for a while circa 2009, but problems with frost and condensation did them in.       --scryptr

im using the stock screws, being a copper base... the stock screws were strong enough to tap the holes.
im  running them at 250mhz still, but its alot more stable and drawing alot less from the usb hub (probably why its stable now)

once i get a few days out of the stick stable.. ill ramp up the voltage a little and try 275.  i seem to have lost the silicone lottery a little, as this stick needs more volts that others have mentioned to get is stable Sad

at least i now have the cooling to keep the voltage under control Cheesy

will post updates as and when they arrive

ps, might use the old cooler on the back of the stick using some of those thick heat pads you usually get on gfx card ram Smiley  just need to find longer screws with the same thread

Sweet project. I plan on keeping the same physical dimensions (though screws may need to be moved depending on chip specifics) for all future sticks. The NewPac heatsink is identical to the 2Pac's. Any gear built for one should keep working on any newer build without a lot of changes.

The screws are M3 thread, shouldn't be too hard to track down. If you get in a bind on long screws, I have a whole case of about 50mm length bought for R808 assembly before that project shut down.

i will keep updates flowing on this sidehack..

as for what scryptr posted.. this has made my head go all silly.

I remember back when i had my old socket 478 P4, with a 200w TEC and a custom water loop (taken from a fish tank and a aircon exchange radiator)

now, i want to get myself a 2nd 2pac if i can get one cheap enough in UK (as i might possibly kill it)
i will get a 15x30mm TEC (about 30w), powered by an old laptop charger i have laying about.

pop an old heatpipe cooler on the top of that, and the stock 2pac cooler on the back. seal it all up with silicone glue to stop condensation.

will probably need to use tension clips to hold it together, as the TEC will block the bolts :/

will remove the 5v feed from the USB port and solder in a 5v 4A charger instead that i have so i dont have to worry about not enough power getting to the unit.

once thats all done, i can crank up the voltage, and see how far it will go hahahah.

not practical, but going to be bloody fun anyway.... i miss the oldskool computer setups.. this will be fun ^_^

once i have a TEC and a new 2pac, ill make a new post with my step by step journey.

ok, small update.
found the TEC, a nice 15x30mm unit that can displace 17.8W of heat. the 2pac at 1.55v will be about 14w of heat (a guesstimate)
this TEC will fit nicely between the original mounting bolt -the center bolt. so mounting shall be easy.

Have a 2mm copper plate to put on the chip side of the TEC to spread the heat too.

Dont think ill bother with a back side cooler as the TEC will pump enough cooling to the chips anyway.

this is going to be totally impractical and go against the reason of having a 2pac (silent, power efficient mining), but its gonna be fun lol.

Behold, the RockMiner U10 USB stick miner which is definitely not a knockoff.


image taken from "the manufacturer"s website

If you happen to see these for sale anywhere, make sure you politely piss all over the seller for distributing what is branded as a unique device but is in fact a relabeled duplicate of my 2Pac. They copied the board exactly (at least the visible layers), and even the product photo on the website appears to be a painted PCB with my green-stick parts photoshopped over top of it. You can see green reflections in metal surfaces. I have received exactly zero credit for this product and only became aware of it today when 419mining spotted an Amazon listing for it.

Hopefully they don't steal anything else of mine anytime soon. I like getting paid for doing work and so do the Gekko assembly minions.

The "behold" is sarcastic, because it's not new at all. If it was new it would be in its own thread but it belongs here because it's a 2Pac with a new coat of paint.

I edited the post to fix the image tag (filesize was too large) and make truth more apparent.

You have any cases of fans left from the project?  I'd like to purchase 20 fans or so if you have them for my R808's

Those black ones are the EU versions, made by sidehack himself. I have one.

It should also say bitshopper.de, which is the EU reseller.

What you told me is that someone in UK was selling NewPacs. Completely different, and they only exist in green. Europe's 2Pacs are supposed to be black, and should name both GekkoScience and bitshopper.de on the back.

WOW. What a ugly scam!

Btw. 2Pacs are official GekkoScience built ones. Also the ones sold in UK, FR, ES, IT, etc. The are black and carry the additional bitshopper.de label plus my WEEE Reg.no.
Everything else is a scam.

Just wait a minute. I'm working out details with bitshopper (the only authorized/legit Euro seller) to stock some NewPacs over there. They might cost in the same neighborhood but can run between three and five times the hashrate.

lol, calm down sidehack.. was only in jest..
you're doing an awesome job with these newpac/2pac sticks.. just a lil moan about europes pricing, not what your doing. ^_^
please dont think it was aimed at you.

(PS, the TEC cooled 2pac is already in progress. just waiting on a few parts)

I didn't think it was aimed at anyone. I was just letting you know that NewPacs would be in your neighborhood soon so if you were looking at buying something you should wait a bit for the better one.

duly noted sir sidehacks.
ill use my 2Pac to rig up the mounting plates and tune the cooler... then once the newpac is in my neck of the woods, i can transplant it to the new stick.

I am getting sick repeating this again and again: NOBODY CAN LEGALLY SELL IT IN EU FOR 40$ if not making a HUGE LOSS. LEGALLY means fulfilling of ALL legal requirements.

Transportation, Customs, Import VAT, WEEE Registration and warranty, EMC testing and certification for CE mark, warranty for packaging regulation, ...

Of course you can import a 2Pac yourself (and declare it as chewing gum in customs). If you are lucky you get it for $40 + transportation without all this crap I mentioned before.

And they plan to add more regulations over the next years instead of less. And for what? For the sake of BIG corp. who can easily fulfill all these ridiculous regulations.
Go and say thanks to your local EU delegate.
