Fan noise on the rMBP isn't as bad as the Air, subjectively.

You can google the objective measurements though.

FWIW I have a 2013 Air 11" and a 2013 rMBP 13"

I ran 'yes > /dev/null & yes > /dev/null & yes > /dev/null & yes > /dev/null &' on both and let them sit for five minutes. Pegs all 4 cores.

After about a minute the Air's fans hit what sounded like full speed, and the keyboard became warm to the touch. The rMBP never made any noise for 5 whole minutes and the keyboard became 'not cold' in one very small area.

I'm really excited about the new rMBPs. I'm leaning towards a spec'd out 15" since it will be replacing my macbook and my imac. I think the main thing I'm waiting to see is if they go with nvidia or amd for their discreet gpu this year. I've been burned by ati/amd cards a few times that I want to avoid them if possible. Why did they switch from nvidia to amd in 2015 for the 15"?

I've seen the fans on my rMBP top out around ~5.8k RPM each, I wonder how fast that little thing on the Air goes. Up for another test, Morales? I don't have an Air anymore.

6,500 RPM, 75 degrees celsius

YouTube HD on an external 27" ACD, importing 25GB of ROMs into OpenEMU, and that yes > /dev/null thing 4x

The keyboard is pretty warm. Not hot to the touch, and the wrist wrests aren't noticeably warm.

6500 RPM with that tiny little thing, jeez. No wonder it whines. They should put a gearbox on it and have it sputter between shifts like you're blowing off a turbocharger.

It's worth noting that the fans in the rMBP are different from the ones in the Air. The blades are supposed to be much quieter and were custom-designed by Apple for near-silent performance or something like that.

I can attest that when I stress out my 15" rMBP, I'm much likelier to notice it in the subsequent performance hit or via the temperature of the chassis than because of fan noise.

Definitely a big change from the polycarb MacBook and MBA that preceded it.

I don't know if I buy in to the Apple distortion field thing. They're simply higher diameter with bigger blades than spin slower, cooling something with a larger heatsink to begin with. The Air has one tiny fan with tiny blades that spins fast.

:anecdote zone: I'm guessing you haven't gamed much on it, as my 2014 15" rMBP roars like a jet engine when I fire up D3, Starcraft II, Civ Beyond Earth, or even Day of Defeat:Source. It definitely gets warm also, but not even putting an active cooling pad underneath it allows the fans to run slower.

Maybe. I still feel like it runs a bit quieter at max blast than my Air did and a lot quieter than the OG MacBook and also takes longer under strain before the fans spin up to audible levels.

With the BlackBook it was like 'connect second display'...3...2...1...'whrrrrrrrrrr'.

It'll be so discreet it won't even have one :rimshot:

Actually some rumor apparently pegged 15s for mid year I think? Main (or only?) technical reason I could think of would be to wait for Polaris (or Pascal if they went that route). As for the switch, I'd guess a mix of pricing and trying to wean people off of CUDA to reduce reliance on Nvidia stuff.

They did asymmetrical fins or something, but I forget if that was meant to change the volume as much as just change the noise to be less noticeable/annoying.

They did. I'm not even sure the asymmetric blade fans went into the rMBP first but regardless they're in everything now.

They do help, and yes it's about making the noise less noticeable. It's basically the same idea as spread-spectrum clocking: you've still got the same total noise energy, but instead of the frequency vs amplitude plot looking like one tall (loud) spike at a single frequency, you get a bunch of smaller quieter peaks at several frequencies close to the same center point. (IIRC the explanation for how this works is that a lot of the noise a fan makes is due to the rotating blades pushing air past fixed surfaces like the spokes that fix the fan hub to the frame. With blades evenly spaced there is just one frequency at which blades have close encounters with a spoke or whatever, with asymmetric spacing you can spread the spectrum out a bit.)

Also Apple sometimes seems to switch GPU vendors just to throw the one that's been mostly out of their product lines a bone. I'm sure Apple would love to have two x86 CPU suppliers they could ping-pong between too, but AMD has never been competitive enough (during the x86 Mac era, anyways) to do that.

It's not quite so much about making the noise less noticeable, but rather as you also put it, changing the frequency of the sound the movement of air produces as it passes through the fixed opening areas of the fan, in order to hopefully be a more "pleasing" sound to the user, but not necessarily quieter. A traditional symmetrical cooling fan with fixed fan blades will have an equal effective opening area between each blade such that as the air speed through the openings increases, the pressure wave propagation due to the differential pressure on each side begins to increase, resulting in an equivalent change in the pressure wave between each effective opening. So it isn't so much that it's air flowing past a fixed surface that causes the sound, but rather just the effective opening area per everyone's favorite Velocity = Flow/Area, and using a form of Bernoulli's equation.

As you indicated, Apple's asymmetric fan design attempts to change how the noise is generated, by utilizing a varying degree of effective opening areas along the entire circumference of the fan assembly. At a given rotational speed, they can deliver more airflow at a lower velocity through the larger opening areas with a resulting lower pressure wave propagation, such that as the fan ramps up in speed, it's a less objective sound we hear, but not necessarily a quieter one.

I work on pump stations and reservoirs a lot, and the above principle comes into play regularly on two areas I have to deal with. One are reservoir vents, where during air exchanges, we have to make sure we're providing enough air flow into the reservoir to prevent a vacuum condition from collapsing the roof or top of the reservoir down. The vents also have to have bird or insect screen on them, so I have to balance the airflow requirement into the reservoir, with the effective opening area of the vent(s) due to the reduction in area the insect screen causes, and then balance that against the fact that above certain velocities through the vent, the air pressure will propagate a sound wave that could be at a pitch and tone loud enough to disturb the surrounding neighborhoods. So in this case, I can't take Apple's approach (since we're limited on how small insect screen can be in size, and making it variably smaller would only worsen the issue), so we take the largest acceptable screen size, determine the highest velocity we can get through the screen without hitting the frequency target, and then increase the vent accordingly to meet that target velocity.

The Apple-similar approach is working on vertical turbine pump bells, where we can see micro-vortices due to the speed of water through the pump bell's basket openings. The baskets are usually installed with pitched blades to break up cavitation, but micro-vortices can develop outside of the pump bell as a result and potentially break apart the floor of the pump station wet well. So I can add a second basket design onto the pump bell with variable openings and pitched blades that allow variable velocities not only due to the effective openings but also over the pitched blades themselves. The blades then also serve to break up the vortices, although this element works of the design is really mostly applicable to water since it's a semi(mostly)-incompressible fluid.

The angle of the pitched blades on computer fans with the little notches/etc. that you see companies like Noctua use are an attempt to simulate that rapid change in velocity and the re-distribution of air stream paths over the blades to minimize the droning hum of air. I will say that, as I mentioned above, my rMBP roars like a jet, but it isn't necessarily the most objective fan noise I've ever heard, just noticeably loud. Which is what Apple went for and I"d say mostly succeeded with.

I'm gonna replace the DVD drive on the MBP with a 2nd SATA drive slot and put in my old HDD.

How do I go about using this as a 2nd drive on the MBP? I now have an SSD installed as my main drive with OSX installed but the old HDD also has an OS on it. I'm reluctant to wipe the drive for timesaving but do I have to do that?

Or can I have two drives with the OS on them and use the 2nd as more storage. Not really sure how that works, thanks!

You could hold ALT during startup and choose which drive's OS to boot from, but why maintain two disk footprints? Wiping it would take all of a few moments unless you're zeroing it out fully.

Oh, okay, not expensive storage. Well, don't keep it as dual-boot, back up your music library... copy it to your main drive if you have to in the mean time, or plug in an external and literally copy over the library. Then wipe the hell out of the second drive. Keep it as a data storage drive, fine, put your photo and music libraries there (make sure it's backed up), but there's no reason to keep the OS around.

My old late 2013 15" rMBP did the same thing and it had a NVidia GPU. It was eventually replaced for free due to Apple Care. I think Apple products just run a bit too hot due to the form factor.

I want to get a 12-inch MacBook to replace my first gen 15" retina. I pretty much only use my computer for work now, and that consists of safari and PowerPoint almost exclusively. I don't need the processing power of the quad core i7 anymore, I need the lightness and size for traveling.

I've been looking at the geek bench scores for the Core M in the current MacBook, and the new Skylake Core M and the new one doesn't really seem all that much better.

Should I still wait for an update? I don't absolutely need it right now, but if I can get a current gen 1.4/512/8 for 12% off refurbished and not miss much with the Skylake architecture I'd do it.

Probably not for OS X, but they probably will be supported in Windows 10 and later, since eGPUs will be ideal for firms that want to provide 3D modelers/drafters/designers/etc., since you could pare a decent i7 PC notebook with an eGPU and replace numerous mobile workstations, etc. and allow the eGPU to just sit on a deck and be connected as needed.

So I'm pretty hopeful that, with Boot Camp, we'll be able to take even a Retina Macbook, run Boot Camp, and have a decent little gaming machine with an eGPU in the future.

The Mac Pro Video Issues program? Well, it's something to the effect of this:

some big ol corp posted:

Apple has determined that graphics cards in certain Mac Pro (Late 2013) may cause distorted video, no video, system instability, freezing, restarts, shut downs, or may prevent system start up. Mac Pro computers with affected graphics cards were manufactured between February 8, 2015 and April 11, 2015.

In addition, the machine has to meet any combo or singular conditions: not powering up, distorted/flickering video, kernel panic/system crashes, or no video out.

No indication as to whether it's specific to the D300, D500, or D700. If a machine tests as bad, you gotta swap out BOTH cards. It's a pretty tedious procedure, too, the MP has to be put in a special stand, you gotta use special templates to apply thermal paste, use some weird calibrated torque tools...
