Again, start reading and stop ranting. That's what I was talking about that you didn't read before.
YOU may have started talking about this "narrow" side bullshit that's frankly to stupid to even think about because no one knew what the fuck you were talking about. Narrow what?!?!? There's only 4 POSSIBLE ways to mount your cpu cooler... ALL four ways will work in cooling down your cpu... ALL four ways will still radiate heat once the system is turned off. Heatsink orientation does not apply to efficiency once the system is off and in passive form.
Explain to me again how you think this heat rises shit works again with the narrow side and shit?!?!
I will dumb it down even more for you.
What I think you were referring to was how much "better" your cpu cooler would radiate heat when the PC was off... When in fact it will radiate heat just the same in any position.
So according to YOU, the radiator will radiate heat "just the same", in ANY position. That means EXACTLY the same heat dissipation regardless of position. IF "any position", THEN radiate heat "the same".
The 212+ has a wide side where the fans mount, right? and there is a narrow side where the fans are now mounted, right? You have seen one of these before and paid enough attention to them to see that they are not a perfect cube? One side is wider than the other. Do you understand that much so far? You haven't understood that much before this post so I am making it clear for you.
I then said, if that were true, then the fan, which is normally mounted on the wide side of the radiator, could be mounted on the narrow side of the radiator (remember, it's not a cube), and it would cool "just the same". And that is not true. The fan speed is the relatively same. The ability to cool at the same rate is NOT the same.
Yours wasn't a new case. Yours is a modified case with fans were there was not intended any to be in the original design. Therefore, the statement doesn't apply to your case.
How do you know? Your ASSUMING that my case isn't new or can' be bought as new. Your ASSUMPTION is where you are getting into problems and still not binding the statement to any set of parameters or conditions using adjectives.
How do you know my case didn't have indented fan slots in the optical drive slots? Again, you are ASSUMING.
Even if they weren't designed, you did not bound your argument in saying stock or modified cases. The original sentence structure still oriented in an ALL or NONE logic set. "in new cases", What about modifying the new cases? would it still matter? But since you didn't set any parameters, its still a simple no, "it won't matter". It only takes one truth to invalid your original rhetoric.
What defines modify? Does adding a case fan consider modification, even if its part of the original design? Even then, what defines new? What if the design is old, but can still be purchased at a retailer, is it still considered new? What if the new case is actually just a modified old design? Then couldn't you say that all ATX cases are based on the AT standards from the 1990's, 1980's and even older?
You said you mounted the fan in the 5.25" drive bays. You said "in the 5.25" drive bays". If they are "in the 5.25" drive bays", then they are not mounted to indented fan slots. Drive bays are designed for drives, not fans. I didn't need to assume that your case wasn't designed for it. You already stated that fact.
In my setup, I actually have two fans in the 5.25" drive bays pulling air in from the outside directly to my cpu cooler and have seen a 1-2C difference.
