Looks only like a very poor photographer's job! crap lighting....

That area in the middle gets no airflow.

Probably going to be impossible to re-glue any heatsinks that fall off.

No, i did that before on my B3 4.86, i made a thermal glue with AL2O3 from reading orginal elecolit MSDS.
if you want to know how is that, i can provide pictures again
it tooks 4 days, 54 chip re pasting is very hard work.

like that , this is my thermal paste 6 times higher thermal conductivity from bitmains black shitty epoxy. 3 times higher then B1 white epoxy.
and also i remove chip cover too.

I used a dot of superglue on two heatsinks on an earlier batch and not wanting to wait weeks on end to ship the hash boards back during Chinese holiday.. Still running strong at 700freq and no issues

I got one for you. PM me your bitmaintech.com user id.
edit: now I have no coupons.

I'm hoping that the one fan version of Antminer S7 is April fools only.

About these coupons, can they be used with hashnest or only for physically purchasing a miner?

I guess that's where the fan motor is.

I think the $115 coupons can only be used on HashNest but the $100 coupons can be used on the regular site. Maybe someone can confirm?

My initial thought as well but looked so questionable I *did* save the pic to look more closely at. Save the pic and zoom in to the 3 o'clock position where the clean area ends. There are literally clods of dust growing in the heatsinks. This better be an April Fools stunt....

The $115 is only for hashnest

I'd love to have one ..

[fvineyard]

So I have a question about using a coupon. I have one listed on my account, but it is not clear how to apply it to my order. There is no place to enter that I wish to use a coupon. Is this automatically applied at checkout or what?

Thanks!

You should see the option to apply it in the checkout.
