Hey guys, so iStat tells me my CPU is at 85 degrees and I'm really not doing anything at the moment other than browsing. I'm wondering if I should be concerned...? My MBP is only about a week old.
 
Either way its not too hot for the processor. Is your MBP well ventilated? Are your fans running? Do the sites that your browsing on have a lof of flash content? Look at your CPU usage on iStat, what does it read?

Um, it's in celsius. So this is not too hot? I was concerned 'cuz all I'm literally doing right now is browsing. Tells me the fans are running at ~2000rpm.

The processor can withstand temps up to 210F. Your at 185F right now so you have a bit of a ways to go before your close. What kind of website was it? Lots of flash content?

First thing to do is check Activity Monitor (in Applications -> Utilities) and see if anything is using a large amount of CPU. This will be the primary cause of any additional heat.

Second, where is it sitting? On your lap? On a flat desk? Proper ventilation makes more of a difference than many would believe.
 
I did check activity monitor and there doesn't seem to be anything taxing the system. It also tells me CPU usage is only 6% with the rest idle. Oh and it's sitting on a desk right now... Should it be at 85 celsius with barely any CPU usage? :confused:

Welcome to the world of hot running macs.

They've made the "acceptable range" wide enough to accommodate hot running. They've setup the OS to shut it down before you watch it melt. Nice eh?

Anything in the background running? See what processes are going on.
If this is yoru first mac you may find that it runs hotter than youre used to.
 
What model MBP do you have?

I have a 2010 MBP 13" base model, and if I have, say, a dozen tabs open, plus a few applications, but not really doing much to speak of (and no flash, etc.), mine runs with the CPU between about 48ºC and 53ºC Fan around 2000 rpm.

Last night I was Skype video chatting with a friend and it got up to around 75ºC (or maybe a tad higher) and the fan was around 3900 rpm. I closed everything except Skype at it went down to something like 65ºC and 2900rpm.

He has a 2010 MB (so basically same exact machine as I do, but the plastic one with a bit less RAM), and his regularly runs about 5-10ºC cooler than mine (if we have basically the same things going on). So there is some variation.

Mine's a 2011 MBP 13" i7 model and I got it barely a week ago. Your temps seem like what I would consider normal. Even the 75 wouldnt have seemed out of the ordinary for me, but I was surprised to see 85 when I literally had 2 tabs open on Chrome :s

Thanks for all the replies guys, I appreciate it. This is actually not my first mac, but I really wasnt too sure this was normal so I thought I'd get some MR opinions :)
 
something is def wrong were you just performing some big tasks then stopped? the only time mine has hit +80 degrees c is after gaming.

Nope no big tasks at all... I was at my schools library with some free time, so I booted it and was browsing and had about two tabs open when I just randomly checked my widgets and noticed the temp. Could this have something to do with the fact that it was sitting on a wooden desk? Think I should take it in to the Apple store?

I think that's pretty hot for just sitting there.

Thats hot. Mine doesn't even get that hot while gaming and all graphics on high. I'd return it. In comparison mine is 34°C browsing, using iTunes ect...

It's a known issue that some MBP's run too hot.
 
I was just watching a video on VLC and had one tab open on Chrome and the CPU was at 55C ... I realize 55 is not thay bad but it seems high considering im using like 10% of my resources.

Normally I wouldve returned it immediately, but I figured the 85 could have been a one time thing. Should I just take it back at this point with these temps?
