Something to look out for when i put the thing back together, either way, EVGA's choice here is an interesting one. Can anyone
confirm whether the blades spin clock-wise or anti-clockwise ? mines in pieces atm lol. I assumed it was clock-wise like usual.
The blades are clearly inverted, and not in the typical orientation you find on standard clock-wise fans. So I'm thinking its anti.

 Just when ya's thought you had another bone to chew on eh, sorry fellas !

Just stopped my 1070 fan while it was running... Counter-clockwise is the answer.

Thanks Scarlet-Tech. Ok so that means towards the heat sink. Do you know much about why EVGA went with the reversed blades ?

Not sure at all. I had actually inquired about counter rotating blades, one going clockwise and one counter-clockwise like they do for dual prop air craft, but I don't think it would work the same for GPU's. I, unfortunately, do not know enough to understand the engineering choices.

I would think with the swept blades that it would reduce noise as the leading edge makes its way through the air, rather than a flat edge causing noise. That is just a guess though.

I know Gigabyte does that with a few of their 3 fan cards. The center fan spins in the opposite direction to the other 2 flanking fans.

Hi DSP1,
 
I can confirm that we are on the same page here.  
 
The thermal pads are in no way required and completely optional as mentioned previously, but if a customer would like us to help them with exchanging their card through warranty to install these optional thermal pads then we are willing to do this even though they are not necessary.  We just want our customers to be happy with their product and if lower temps are preferred then we we willing to help with this.
 
I can confirm that Jacob is one of our product managers and he has access to all of the ins and outs and anything that he says is true.  I am just trying to explain that the cards are running within spec and not overheating without this optional mod.
 
 

How can you say you are on "the same page", and at the same time you are saying something different?
 
Quote:
In our discussion with EVGA's Jacob Freeman on the phone, we also learned that EVGA would replace users' cards at no charge to the user. An owner would have to send the device in to EVGA in order to receive a new device with the thermal pads pre-applied.
Quote end.
 
Clearly I read NEW in that quote.
 
Your sentence quoted here is inconsistent. You are basically saying "exchanging their cards"
and "help to apply" in the same sentence. So unless "help to apply" is a mistake, you are not
"on the same page".
 
The way you say it, AVGA is applying thermal pads to the cards your customers are returning, and
then returns them. At the same time you say that the cards gets exchanged, and since you are "on
the same page" as Jacob Freeman, the cards will be exchanged with NEW ones. 
 
I certainly don`t want my cards replaced by used ones that have been abused to the braking point 
by another customer, just to have my cards fail after warranty expires due to degraded components
caused by this problem.
 
Understanding that the cards will be replaced with new ones, will we be offered cross ship?
 
You need to clarify this...
 
 
Cheers :)

Just quoting you because you are involved in this mini discussion about pull/push.
The FTW Hybrid fan is in pull mode, drawing heat off the sink and blowing into the case.
Review by Gamers Nexus commented on this. 
So are both fans on the ACX 3.0 pulling air off the sink or are they pushing air into the sink?
If they are pushing air into the card with the blades being reversed (in pull orientation) that would be rather stupid.

The fans pull air from the bottom of the case, into the fan, push them into the core heatsink (all of the fins and such) then onto the heatspreader. Hopefully that makes sense.

All gpu's flow air the same way with these two designs in the picture.. I just tested it on my 1070... With a M&M's wrapper.. Judge me, I don't mind... I held the wrapper in front of the fan and it sucked it in. I put it next to the edge of the cooler and it blew it away... It was a very technical test, I promise.

zotac 980 amp extreme (not core version) has very unique cooling design. it does has push and pull fans at the same time.
