The title says it all. It seems like it's running a lot warmer compared to Leopard.
do you have any concrete numbers to compare?
Have you tried installing smcFanControl?
No. I can feel it while resting my palm on the palm rest. Normally on Leopard, I won't feel hot or cold.
I'm running smcFanControl, and my temp is running 12 - 17 degrees Celsius warmer than it was before the SL update. Not good.
me too, I have the umbp 2.4 usually the fans would start to kick in when i reach 70 C on the CPU (throttle automatically to 3000 - 4000 rpm), now it starts when i reach 85 C....
Perhaps spotlight is indexing?
Good thought, but Spotlight isn't indexing on mine.
My UMB used to idle at ~50. Now that's ~60 or so.
Can one see if Open CL is being run and the graphics card is used more and giving thus more heat?
Woah 10 degrees? That's a bit much for laptops! SL sold out in all the stores in my area today, so maybe not being able to buy it was a good thing
I'm at 70C with absolutely nothing open but Safari....
CPU is 72C now...with 9% load...wtf
How's the battery life? More heat=more power=less battery life...
Not sure I'm plugged into the wall. I tried switch back from the 9600M, CPU is still hot, restarted, everything.
Mail & Safari only programs open, and I'm running at 65 to 72 degrees Celsius. Before the "upgrade" to Snow Leopard, I was running around 50 - 53 degrees Celsius.
My blackbook battery has taken a hit, but I'm going to let it calibrate a bit for the next day or so, and see what it looks like then.
Same problems here After installation, my umbp runs ~15 degrees warmer without anything open (73c). SmcFanControl running knocks it down to 63c, but it shouldn't be this hot. The indexing finished awhile ago.
That's the first thing I noticed after install
2.4 mbp 4gb ram
Before SL: average about 43-45C with Calendar, Mail, Adium and Firefox
After SL: average is 60-63C with the same app open.
PS: comp runs warmer with every new update for the leopard
So after taking the plunge and installing SL (just a regular upgrade install) I found that yes, CPU was sitting at 65-70 compared to the normal 55.
After one reboot and at least a half-hour of just idling, cpu temp is steady at 44, so it's running even cooler than usual! This is on a SR 2.2Ghz MBP that idled at 55 on Tiger and on Leopard. I also gained around 12GB extra space after the install.
okay, you guys and gals are starting to make me think twice about installing SL when it comes to my house next week.
warmer CPU temps is definitely not good. I think I'm gonna sit back and hold off on my install until I start hearing something better. I only spent $10 on my SL disk so it's no biggie if I don't use it.
Definitely running hotter in SL...
I have a 2.5 Mhz C2D (Macbook Pro 4.1) and just by browsing the web my CPU temperature climbs to 65 to 70C.
Right now, for some reason my GPU temperature is 73C.. I'm not doing anything that would tax the GPU, just browsing the web.... No flash, no videos, etc, just browsing.
Mine is also running hotter. I used to idle at around 46-48C and now I'm at 57C with nothing going on but Firefox and Transmission
Mine's running cooler. In Leopard, its ~50 deg C idle, now in SL, its ~38-45 deg C depending on ambient temp
Mine was running ~10C hotter right after I installed SL (and it's required reboot).
After rebooting again, I'm down to about ~1C warmer than Leopard.
Wow - looks like I'll be holding off on an install as well. What I don't understand is that, given this is by no means an isolated thing (judging by the number of people in this thread alone who have experienced it), why on earth would Apple not have noticed it? Or am I being unreasonable?
Roll on 10.6.1.
