Hey guys,

i just obtained a few heatsinks for myself for additional cooling of different things like raspi or Bitfury chips passively.

The heatsinks have a size of 11,5x11x5mm and a 3M glue sticker for mounting on the chips is already attached.

I would sell a few of them in lots of 16 pieces(for mounting on 1 Bitfury board), i would ask 0,1BTC for 1 lot excluding shipping. Iam located in Europe but depending on the amount of heatsinks, shipping wouldnt be so expansive to anywhere i think.
New offer:
20 pieces of heatsinks for 0,1BTC

EDIT:

Just saw that also ASICME, a chinese avalon clone manufacturer uses similar sinks for testing purposes ;)

32 pieces are left

this makes 0,25 BTC including shipping for them.

Anyone still in need?

still 32 sinks left here :)

maybe soon also full heatsink plates

I would buy some if you can tell me for sure that their height does not interfere in any way with an adjacent h-board (for example when using a starter kit with multiple h-boards).

My face when you get this stuff cheaper than I could, even though I live a relatively short drive from their global headquarters...

So Foofighter did you read my post? Have you tried them with an adjacent board and not just standalone?

Hi,

not tested so far, had no time, just came back from vacation.

Ah ok, hope you had fun! :)

Why would they add heat sinks to the TOP of an Avalon board?
The packaging of the Avalon chip has the chip die bonded to the bottom side of the carrier, and rejects heat out the bottom of the chip.
Which is why they have those large thermal via's on the bottom of the board. There is a air gap between the die and the top of the chip carrier.

Adding heat sinks to the top of an Avalon doesn't do anything. It just costs money.

you are right, the back side is prefered but from temp measurements there isnt so much difference between both sides in temp.

I ordered new heatsinks because many people asked for it, should have them in hand in 1-2 weeks.

So Iam open for new orders here.

cheers

First few hundreds are sold.

See here a picture of 1 of my hashing cards:

Hey guys,

if there is interest I could also offer a few of those full heatsinks:

they are custom reworked by myself and I have only a handfull of those at hand now for personal useage mostly.

Iam also not sure if the fit in a fully populated Rack as the have a height of 15mm, I would probably only use them if you have only a handful of cards and always a free slot behind a card with this sink.

Pricing would be 0,12 for each piece excluding shipping

cheers

still available

Are ther any heatsinks that use holes on bf board for tight fit?

see 2 posts above?

Yea, but it uses only two middel screws, isn't it?

its totally fine to use only the 2 middle screws, in my opinion.

The sink plates I have are not big enough to use all 6 holes.

Price reduction!

I will now offer every package including 20 Heatsinks instead of 16 for 0,1BTC

So also your power regulator can get cooled accordingly and you OC potential and life time will increase

still available

cheers
