MacBook Pro over heating after upgrading to OWC Aura 480 GB SSD?

HI

I upgraded my MacBook Pro with a OWC Aura 480GB SSD recently. I completely wiped it and installed MacOS Sierra everything was working fine and after a day or two my MacBook Pro started heating up! I installed SMC FanControl to see the temp of my system it shows 55 to 60 C (131 to 140 F) always even when I am not using anything. I tried SMC reset and still no use. CPU usage is normal and RAM usage is normal. I have 16 GB RAM.

What can I do here? Reset the system again??

Answer this question I have this problem too

Is this a good question?

To start with your system is not running overly hot here. What maybe confusing you is your system was running before you upgraded was cooler!

Lets backup here a bit...

When you install a fresh copy of OS on a clean drive and then install your apps & data from a backup the OS needs to do some background tasks.

The biggest one is indexing all of your files so the search tools are able to work. This is by far the biggest process which will heat up your system for a while. There are other processes depending on your systems configuration and the Apps you are running.

Lastly, the size of the drive maybe too small! This is a common issue when upgrading to SSD's as the amount of free space they need to run efficiently is a 1/3 for the smaller drives (256 GB and less) or 1/4 with the larger drives. If you're on the tight side you may want to do some house cleaning. I mostly see this with the older HD based systems are upgraded.

Even after upgrading SSD and couple of days later .I see the same issue .I can feel my MBP heat near the track pad and backside of the MBP. At first I though because I am doing all this Backup and Restore thing it is happening.But when I use it for regular use I can feel the heat. There are no background apps running .I tried a fresh install of MacOS without installing any application and just using safari and I still see that MBP getting hotter.

I think you'll need to give OWC a call: OWC Customer Support to see what they have to say.

Just make sure you hit all 4 keys the same time - with no delay between any key.

Hope it helps...

Make sure that your SSD is properly seated.

When you insert the SSD blade into the slot, the gold connector shouldn’t be exposed. If you can see a good portion of the gold connector, the heat from the connector will dissipate into the MacBook Air.

This is because the connector is a metal and the electrical conduction generates heat, warming up the metal. Because the connector is exposed in the air, there is no heat sink to absorb the extra heat. This extra heat will not properly escape the MacBook Air or MacBook Pro and will cause overheating.

Below is an image of a properly seated Aura Pro X SSD Blade in a MacBook Air. There is minor exposure of the gold connector. This picture uses the included Thermal Pad. The Mac Pro uses a heat sink which can be purchased separately.

WARNING

Very carefully try to push the SSD in further. If you push too hard, you risk damaging your Aura Pro X or your MacBook Pro or MacBook Air. It might help to remove the SSD first and then push it back in.

Here is a photo of the connector. It is the gold part on the left side of the image. This connector should not be exposed when seating the SSD into the slot.

Not sure where you got the idea the connector interface was a heat sink.

There is no validity to your statement. True, the connector interface needs to be fully seated. If the mount screw is in place then the Apple blade SSD is seated correctly.

Hey Dan,

You are correct, the heatsink is a separate issue. The heatsink model is:

AURAPROXHS

https://eshop.macsales.com/item/OWC/AURA...

This is required for the Mac Pro and not the MacBook Air.

However, the SSD will screw in properly with the T5 screw even if it is not properly seated.

The difference in just one millimeter will expose the connector and allow the heat from the connector to dissipate into the MacBook Pro.

To clarify, there shouldn't be any exposed gold connector when screwing in the T5 screw to secure the SSD.

You need to carefully push the SSD in all of the way, otherwise you risk overheating.

Again the gold contacts are electrical not thermal. As long as you have proper electrical connection the depth of the insertion is not an issue.

FYI: The mounting screw sets the depth. I've put in 50 or so in and never had any issues with the blades connection. There is a bit of play by design.

As far as the heat sink that is only needed in the 2013 Mac Pro trash can systems. It is not needed in either the MacBook Air or MacBook Pro systems. The Mac Pro pushes the SSD hard hence it gets warm. The Air & Pro's are not able to push the SSD to the same levels and as such don't need the heat sink. Besides, you will damage the drive from compression from the bottom lid pressing on the drive via the heat sink.

Hey Dan,

Thank you for the clarification on the Mac Pro and Heat Sink. I updated the answer to replace the error.

The electrical contact is exactly what I am describing.

It's possible to fasten the T5 screw on the edge of the hole, somewhat exposing the electrical contact. The heat generated will warm up the metal next to the contact, and that portion of metal is exposed to the air.

Maybe I'm mistaken, but on my first attempt to insert the blade I did not push it in all the way and observed my MacBook Air using the following terminal command:

sysctl machdep.xcpm.cpu_thermal_level

machdep.xcpm.cpu_thermal_level: 128

It was running hot even though I wasn't doing anything processor intensive.

I then pushed the SSD blade further into the slot and it solved the issue for me.

by

No heat created or dissipated from the gold contacts of the connector. The design of the connector is designed to touch the mid-point of the blades contact pad. As long as the contact is properly touching with no resistiveness in the electrical pathway there is no possibility of heat creation.

If you look at the edge you'll see some pads are different lengths this is by design as you want ground to make contact first and power last. So if you fail to insert the connector to the point the contacts make contact then you can encounter odd problems. Just like you encountered the system won't have the needed connections. But thats not a heat issue thats a basic failed connection issue.

Review the comment in Thomas's post below on why your SSD is running warmer that you think it should.

I got two of that same model and used them to upgrade two MacBook Airs, one 11” and one 13”. Both run a lot hotter than before (I never noticed those machines getting hot at all, before), and unsurprisingly battery life has also taken a big hit, cut almost in half. The upgrade was months ago, so whatever indexing might have had to happen is probably finished by now… These are just weirdly power-hungry SSDs, and it’s annoying enough that I’m thinking of replacing both, despite the expense. Not recommending this brand to anyone!

Depending on how full your drive is you can encounter over heating. This has nothing to do with who's SSD you are using. The issue is the garbage collection and wear leveling the SSD needs to do. So if the drive is overly full the drive needs to work a lot harder to move things about.

As a rule of thumb you want to leave 1/3 of the drive unused if the drive is 256 GB or smaller. For 500/512 GB drives I try to do better than 1/4 and for 1 TB drives or larger 1/4 to 1/8 left unused. This allows the OS to have the needed elbow room for Virtual RAM, Caching and Paging.

As far as the OWC drives they do run a bit warmer than the Samsung drives. The reason they do is they are using dual channels across the flash chips to offer better performance. The newer Aura Pro X SSD runs cooler.

Here's a bit more of Virtual RAM

The bottomline is free up space! The SSD will run cooler!

I used those drives to replace the original, smaller drives. The new drives are half full.

The issue of space is not true. I have the 2TB version of OWC Aura Pro X SSD and I am having tremenous oberheating problems. I have done all pram vram all possible resets. I thing OWC is just a crap company. Any other solutions?

I would recommend if you have such a bad issue you talk with OWC to see whats happening.
