rMBP high temps & fan always on w/Safari

[axlvtt]

Hey guys:

I've been having an issue with Safari lately on my MBP 15-inch retina laptop. On idle my CPU sits at 50 degrees, but when I open Safari it jumps to over 100 degrees. I am using Chrome right now and the CPU is at 52 degrees. Does anyone know what the problem is?

Most likely, Flash. For Flash-related issues:

• Find your Flash version and make sure it's the latest version available. Never install or update Flash from a pop-up on a website. Always go to Adobe's site to get Flash or updates.
• Install ClickToFlash (Safari), Flashblock (Firefox) or FlashBlock (Chrome) to control which Flash content plays on websites.
• Try using the YouTube HTML5 Video Player to watch YouTube videos, when available. (May impact fullscreen viewing. See link for details.) Some have reported better performance with HTML5, while some have reported worse. Try it and find out what works best for you.

Use a dedicated browser for porn and a different one for surfing, will make your life a lot easier. Oh, and stop using flash.

Are you talking C or F? If C, then here is your problem:

Correction: that's only one possibility, which doesn't apply to the majority of Macs in use. That is the fallacy in the title of your thread that you linked: it does not apply to all, or even a majority of Macs.

Flash will consume system resources and drive up heat, no what thermal paste or other cooling methods are employed. There is no need to mess with the hardware in order to keep Flash under control. The apps mentioned earlier will help control which Flash content plays.

This is good advice. This is what I do. I don't even install flash on my system anymore. Why would I when Chrome has its own flash built in?

So for any flash videos I encounter, I open up Chrome. For the rest of my browsing experience, I use a proper browser like Firefox/Safari. It's really surprising how fast Firefox/Safari is when Flash is not installed on the system. Try it out.

I use Flash regularly on mine with no lag at all. It also doesn't trigger the dGPU at all times, sometimes only the iGPU does the graphics output.

I've noticed this at times, and haven't checked into it more - it may be that non-HD stays on the integrated, with HD on the dedicated GPU.

Don't have any issues with my 15" RMBP.

However as soon as I got it, removed and re-applied the thermal paste then installed flash blockers.

Did you happen do to any before/after temp testing?

Its been my experience that any savings in re-applying thermal paste is small at best.

I'd like to know what temps you were running before removing the thermal paste and after.

 

[Lyshen]

Good question, sadly I don't have an answer for temps before and after.

Once i got it, only things I did was verify it was a Samsung display and not a Sandisk SSD, then did the thermal paste.

I know Apple uses a lot of thermal paste (seen lots of Retinas and cMBP/Airs with loads of paste), that's why I wanted to reapply it even though I doubt it make a huge difference. Plus on a Retina it's very very easy to access.
