Temperature of Computer

It feels like my MBP has been running fairly hot lately. this has been for like 2-3 weeks now.
I usually have Activity Monitor, Mail, Chrome, iChat, iTunes open.
i dont know if my stats are normal or not though.
it gets hottest right around the charger port and above the F1-F4 keys.
is something wrong? it gets old feeling this huge amount of heat radiating from the computer. especially on the keyboard. typing on a hot keyboard isnt fun.

its also been fairly laggy lately. things take longer to start up. beach balls like hell. and just over all stutters.

usually when i check the stats RPM sits around 2000+ and CPU around 150F
 
Mine is doing the same thing, running about 7 degrees warmer overall. Called apple and they suggested i spend money to put it in their shop to have "thermal glue" added
 
id be okay with the heat if i couldn't feel it as much.
every time on this computer my left hand feels so awkward since its so hot.
that corner literally hurts to touch.
 
Those temps seem normal ... under normal/lite load it's 70ºC+, and can reach near 100ºC+ when it's warm in the room and i'm encoding and usage is maxed out.

That said, you're 158ºF seems pretty normal seeing as the 150's is around 65-70ºC
 
so its the fact that its alluminum that it hurts to touch? like right now its at 162F and holding my hand there does cause pain.
 
I usually am in the 117 - 133F range under email/browsing conditions. However, I'm also undervolting using CoolbookController and I think that contributes a wee bit.

The case probably isn't 162 degrees.

You can run SMCFanControl to cool it off. I have my fans run at 3000 RPM all the time. I also keep my MBP on a passive aluminum cooling pad that typically keeps it 5-10 C cooler.

Those temperatures are degrees Fahrenheit. Which means the temperatures are alright, but could be lower (assuming the computer has been idle for a while now).
 
I know, but if the CPU is 162F, it's not likely that the case is also 162F. Otherwise when the CPU was 90 C (as some people with 13" Unibodies experience), the case would actually cause burns.
 
It does seem quite warm, for the same model my temps are CPU 112, enclosure base 79-85, heatsink 104, fan 2000 rpm. All in F.

I'm a bit surprised your fan is at 2500 rpm. Mine never moves off 2000 rpm when the computer is idle. Maybe you have some rogue process exercising the CPU? Although it doesn't look like it from the CPU level in your iStat.

On the whole it looks like your Mac is working fairly hard... harder than a computer at idle should be.... Odd.

That's the thermal grease, metal loaded gunk which sits between the CPU and the heatsink, to carry the heat away from the CPU better.

Good thermal grease reduces the temperature difference between the CPU and the heatsink, especially when your CPU is working hard.

One way to tell if your thermal grease is "good" or "bad" is to work the CPU hard (eg Handbrake, or open 2 x Terminal windows and type yes > /dev/null into each one) and look at the CPU and heatsink temperatures. On a few MBPs I've looked at the difference is about 20-25 C (maybe 50 F ?). If your difference is WAY bigger than that, you may have a thermal grease problem. Otherwise I doubt that sending it to Apple would make a big difference.

But I don't think the OP has this problem, his CPU and heatsink are within 18 F (about 9 C) of each other, OK so his computer is idle not working hard. It would be interesting to know what happens at full load.
