Thank you very much KNC!!

All four Noveremmmbbberrrr come late, but all is working perfect.

Everyone has 670 to 672 +-1. You are the best!

Now you can offer an other firmware so that we can have 1 Th/s per Machine.

If you develop one i will pay 1K for each machine.

thx

Just received my November Jupiters and there is damage. Here's the email I sent to support:

I just received my November batch Jupiters and 2 of the ASIC chips are extremely hot, reaching over 86C in a very cold room, which cannot be kept cold as it is the living room. The other ASIC chips vary in temperature from 38 to 57 degrees.
I removed the heatsink from the hottest ASIC to re-paste it and as you can see in the pictures provided it has been severely damaged during transit.
The base consisting of 4 copper pipes is supposed to be perfectly flat, so it has perfect contact with the heat spreader of the ASIC chip, but the pipes have been misaligned and bended and currently they do not sit at the same level as seen in the pictures.
The original metal plank that sits directly on top of the pipes has fallen off even though it is not supposed to as it is glued to the pipes.
Because of the uneven contact surface the whole heatsink is tilted backwards.

Also recently I bought an October Jupiter from (Phoenix1969) from Hawaii and it also arrived with one of the heatsink damaged it the same way. Until yesterday I was convinced it was damaged by being dropped as it looked impossible for such damage to happen during transit, but now with the units I have received directly from you it is obvious UPS are at fault. And his unit was packaged much better than yours - 2 separate boxes and a lot of thick bubble wrap.

The ASIC chips + boards are fine - it is just the coolers that are damaged. I have already ordered a replacement cooler for the Jupiter, not received directly from you, but would need to order 1 or 2 more for the damaged ones you sent me. I will appreciate it if you can pay for these or just sent me replacements.

Thank you.

THink that's bad? All ya gotta do is buy new heatsinks  , here's mine:

oh shitttt

exactly why they need to put foam or air packing into the case for shipment. sigh.

If the units were damaged by shipment, via dropping or whatnot, and the heat pipe moved out of place.. why not just move it back in place? Am I missing something? The force of the drop moving the pipe can't possibly be much more than a few pounds.

True. Mine are easy to fix. I just have to leave the window open until the new coolers arrive.
I wonder what have UPS been doing with the package. Play football?

Look at how big the difference is in temperature:

I tried forcing the pipes by hand to allign so they make a flat surface, but they are not moving and I am afraid that if I apply too much force I can do even more damage.
I might get a small hammer, put a piece of rubber or other cushioning material and hit the end of the piper on the top of the cooler downwards.

Yeah try tapping it with something heavy like a hammer or a wrench or something. You could put a flat piece of metal against the pipe, it would help line it up automatically when you tap.

If that doesn't work, it wasn't damaged in shipping, it was likely defective to begin with. This is based on simple physics.

That's a precision machined surface.  You will never be able to get it flat enough by hand.  Just buy a new cooler, and hopefully, get KnC to reimburse you for the damaged one.

It's simply lapped/flattened, it's not measured on a micron level. You could use a flat piece of steel (CNC'd flat preferably) to align it.

I suspect it was like that from the OEM though, and not through shipping.

no hes saying its actually bent, its hard to see in the pics but i know what he means. the pipes would barely contact the chip

Could you use the flat bar (on the processor side) and the integrated bracket that came unglued to make a sandwich around the heatpipes?  Then use a c-clamp or locking pliers (vise-grips) to squeeze all four pipes back into proper alignment?

[vesperwillow]

Henchman24 kindof gets what I'm saying. Even if it's bent, it can be re-aligned. And if it can't be realigned, it was likely not damaged in delivery, but a defect from the OEM.

[CYPER]

I think "bent" wasn't the best word to use.

Some copper pipes are slightly off level = not even surface.
The surface of each pipe is completely flat = no damage there.

So tapping them on top of the cooler might make them move downwards, thus alligning them on a horizontal plane.

I might try that a bit later.

Just use a full tube of thermal paste! That'll fix it right up! lol

Mine was damaged as the front screw on the support bar wasn't screwed in, so the heatsink has free reign to bounce around. It's already back on it's way to KNC.

I wonder what kind of people work at the factory. How can you forget to screw everything right or leave the plastic cover on and still apply thermal paste all over it. Even a blind man will feel the plastic being on and remove it.

They're not looking to catch these small misalginments. They're likely popping the stuff together, and turning it on for like a minute to make sure it "seems right". They were under a huge deadline.

This is part of the reason I believe KNC is making such a vague prediction of the next shipment. They know the crap they have to face with the new product, and they want more time to get things right.

After bending them back mostly right, you will still need to sand/lap the bottom. Be careful not to sand it down too much, if that gas in there escapes, its game over. Actually, that may already have happenend if there is only the tiniest of cracks. Ive ruined a fair number of GPU coolers trying to bend the heatpipes on a certain type of cooler to elevate them above some high caps on my cards. No visible damage, but cooling performance was terrible and you could simply feel that some pipes no longer got warm like the others, despite perfect contact surface.

or you could just buy a new one.
