Late reply to the thread 8 question about Zotac - I'm starting to have fans fail on the few Zotac mini cards I own.
I can NOT recommend most of their cards (or the NEW model EVGA stuff) due to their use of "fancy name" sleeve bearing fans and the resulting FAST FAILURES on those fans.
I'm more than a little ticked off at EVGA lately, as they're moving across the board away from their long-time use of GOOD ball bearing fans to JUNK - first it was the bloody G3 power supplies, now their graphic cards....
I haven't ever used a Zotac brand GPU, however I am aware that they are more on the cheaper brand of aftermarket GPUs.
Regarding the sleeve bearing fans, are those similiar to those of the Gigabyte Windforce series type of fans? They were notorious for failing constantly due to the bad design and always allowed dust to come inside the bearing and caused them to fail prematurely.
I have RMA'd a bunch of them only to get the same issue about 6-12 months later. What I found is best for those fans was to take some floss and put it around the fan blade and pull the blade off, and you can see the bearing and oil it with mineral oil and it'll last another 6 months or so.
Basically I got so good at it because of the frequency that they failed that its possible to perform it while it was still on the rig. So maybe try and pull the fan blade and try to reoil the Zotac GPUs instead of RMA'ing them.
zotac amp extreme isn't cheap, it is the top tier of the lineup, clocked higher and better cooling. i have 1 1080ti aorus extreme, fans are working but i think the cooler design is sub par compared to amp extreme, i used liquid metal on it and put 2 PWM fans and it's very cool now.
amp extreme - top tier of zotac have 'sturdy plastic' fans, that's why i was able to pull it off while it was still mining. and being on a riser helps because the cable moves when handling but not affecting the gpu-socket connection (unless gpu is screwed-steady just like in a typical case).
December 2017 hack was probably an inside job--->sell high, refund through repayment program
just like cryptopia hack February 2019 hack--->buy low, refund users in fiat with a lot of deductions(hack, expenses etc.)
they all stink of inside job, they know stuff, they know how things work and they think they can get away with it...with so much money on their hands it was irresistibly tempting.
if they are gone, someone will simply replace them.
