Well it doesn't take an official or unofficial review to tell me what I'm holding in my hand is what exists. It is what it is, nothing more nothing less. 2 for 2 were crap in horizontal mount so I guess it's good for them I wasn't an official review site isn't it. Anyone and everyone is welcome to roll the dice on anything, the op asked and I merely shared my own real world experience. 100 great reviews doesn't make the product I personally received any better. I already spoke of others who've experienced the exact same I noted, it doesn't have to be a reviewer to exist. The moon doesn't need a scientist's official seal of approval to see what's right in front of someone's face either. Hopefully the op will get perfectly fine fans. Not sure why it's so hard to believe that they have the potential to run poorly in a particular orientation, other fans have similar issues as I stated before. It really doesn't have to do with whether the bearing is of one design or another, just that it failed in the orientation I tried to place it in. I never said the phanteks would wear sooner, which is the common association with sleeve bearings in a horizontal orientation - premature wear.
Argue how wonderful the fans you received were all day long doesn't change the conditions the phanteks fans I received exhibited. It's a fact that some aren't up to par and take for what it's worth. In at least one user's experience, 2 for 2 with the same issue.
My only comment about their lack of displaying information proactively was it tends to be a matter of hiding something. Noctua and others go out of their way to be transparent, phanteks chose not to. It's not about how difficult the information is to obtain. If you have a new product different enough to label it something apart from everyone else (as in not just ball bearing, dual ball, sleeve), to actually give it an acronym as noctua has their sso and sso2 - why wouldn't you explain why and how it's different? If nothing else clue in those who you submitted product to for review knowing full well it was being reviewed and advertised to others.
Same reason some products are sold and advertised as 'all metal construction' and others sold as 'rust proof'. Why, because calling it what it is, "plastic" doesn't sound so fancy and they're not quick to tell it like it is. Mattresses, same thing. Check a sealy or serta sometime and the construction diagram of vague wording like 'durable long lasting material' or 'airflow foam' - aka cheap eggcrate crap and no densities listed. Go look at a quality made product and they list the specs for all their materials and don't use cheap fillers as a means of corner cutting. Companies know the market, know the questions people ask and what things are important to them and it's no accident when things are kept on a need to know basis rather than proudly displayed. That's all.
It shouldn't have to be argued when someone shares their personal experience as if what actually took place somehow did not or is in any way invalid. The op can take it for what it is, just a shared experience and didn't cost them anything so they're not out anything. I wish them the best and my only intention is to help. If it weren't I wouldn't take the time out of my day to post. Maybe phanteks have incredible fans suitable for all positions but if that's the case then quality control needs to step it up so someone who receives one of their cases doesn't receive defective products. For me personally it wasn't worth the headache of rma'ing since they did work in the orientation I'm using them in and noctua had better quality fans for roughly the same price since I was looking to add additional fans anyway.
The rubber grommets on the corners of the retail versions are a nice touch but any anti-vibe pads should be nothing more than a precaution. If a fan vibrates that horribly, first off it's defective. Second, if it has as much vibration as mine had the pads wouldn't have helped. In contrast the noctua's had no pads either (redux) and are hard mounted with screws and no vibration is transferred to the case. There's no vibration at all to begin with.
