Hi guys!

So I was very excited to get this new Macbook to replace my older MBP. I know this guy has no fans but it feels its getting rather hot when on my lap for example. I don't have any demanding apps open like photoshop and I don't do any video editing etc. I pretty much had Pages, Keynote, Mail, Messages and Safari with a couple of tabs open. Just wanted to know if anyone else can report similar situations.

All in all it works really nice, I love the keyboard now (I didn't think I would) and it's pretty snappy.
Macbook Retina 1.2ghz 512GB model (Gold)

Thanks!
 
Amazon instant video heats mine up on the bottom quite a bit. I don't care though because I don't see any issues with performance. Doing things like web browsing and typing documents mine doesn't get warm.

Make sure you're using the HTML5 Player version. That should cut out the overhead from silverlight/flash player.

I also have the Gold Model, I more so notice the heat in the center of the Speaker Grill. It does indeed get very hot depending on the load (Especially when Compiling Software or testing AI algorithms.), to the point at which it will throttle down. I've recorded temperatures into the 114F range on the surface with my Thermal Instruments.

Matter of fact, I've gotten it so hot at one point I had a red burn mark on my stomach while lying in bed without a shirt on. The Macbook 12" uses its Chassis as a Passive Heatsink, even with the Core-M being such a low TDP SoC it's more than enough to be able to creep into the 80c range if conditions permit.

How do you make sure you're using HTML 5 instead of Flash on player? And on You Tube for that matter.
Thanks.

Dont install Flash, or if installed uninstall it ASAP, unless you need it for something critical.

Youtube can run in HTML5? problem is I see many news sites among other things request the flash be installed to view. Is there a way to get certain things to play HTML5 vs flash? Thanks!
 
Mine doesn't even get warm, it's cool to the touch, and that's while running videos from iTunes, Netflix, HBO and youtube.

But mine's the 512 GB storage version, not sure if that matters or makes a difference.

Yeah I have the 512GB 1.2ghz option. I mean the entire laptop isn't warm, it's mostly just in the bottom center area where the logic board would be. I guess it's normal.

Which browser are you using? Safari, Chrome, IE, Opera, FireFox, etc? If you're using Chrome it should be HTML5 out of the box. I've been using Youtube as HTML5 since the Developer Access in like 2013.
The amount of overhead in Adobe Flash player vs HTML5 is mind boggling.
 
After following some advice from people around here, I uninstalled flash completely in my usual browser (safari). That way, any sites that would auto select between flash or html5 will not have the option to use flash. I also installed an adblocker for the first time (ublock), mostly because I wanted to keep things zippy and maximise battery life. Doing all this has probably made a small contribution to keeping things running cooler too. If I ever do need flash for a specific site I just open Chrome, because it can run flash without needing it installed (which was again some useful advice from here).

In any case, my machine honestly never gets significantly hot even when caning it hard. I think the processor choice has something to do with this. From what I've read (mostly the big anandtech review of the MacBook), it seems that the 1.3 model somewhat ironically runs coolest. I was worried about getting the 1.3 because I thought the opposite would be the case - that for a pretty minor speed improvement, the payback would be running hot, chewing through battery and throttling down more. But in my experience it hasn't been like that at all. I guess maybe because the base model is working toward its upper limit more often, perhaps those machines can get a little toastier?
