Good luck in the upcoming Havelock IPO Smiley

That is interesting video right there...

Those chips don't seem to get the Novec vapourizing much. Speaks well to the SP10 as an air cooled unit. SP30 board be keen to see that.


Quick introduction, since this will be my fist post here. I am a work colleague of antirack, and I am the one that have been doing the setups for this "lab" tests.

I have been running the SP10 for quite a while now, it works great, just not very optimal circumstances for the boards as they had to be placed horizontal and heat dissipation side down. Hence also a bit tricky to get a good recording of the action, if you so will.

Short explanation: Unlike AM Gen3, we designed the our 1st gen ASIC (Hammer) to dissipate the heat downward, which is far better for QFN package, in our opinion.

I am pretty sure same goes for the BE200 ASIC, but I leave that up to you engineer guys. My comment was of course not meant be negative in any way, just explaining the situation of this tests. I also intentionally kept the ASCI side up to make it look more interesting then a big copper plate. Hopefully soon I can show some boiling action of both sides in a better way.

You could see a lot of action (vapor bubbles) escaping through the mounting holes and out from under the edges of the board as the vapor builds up under the board it makes for an interesting show but obviously this is not the normal configuration. If it were a vertical setup you would have that rolling "boil" look I suppose. It just bet the SP10 board so well designed that in comparison to a smaller pcb of a higher density with 'older' hotter chips is comparing apples to dragonfruit with the SP10. They don't really need to be in Novec with those Hammer chips, but if you had a much smaller blade maybe that would be required. It be great to get some numbers on the SP10 especially can you overclock the snot out of the Hammer chips in the Novec even laying flat? Or do we all have to wait for Inside Bitcoin Hong Kong to learn more about the potential? I can't wait to get to Allied Control and check all these things out.

Curiosity!
