    I was wondering if any of you have your MBP on continually and how it does with heat and performance. I am thinking about buying one to use as a mobile media center PC, namely sort of what I would use a mini for to hook up to my 1080P LCD TV (WoW on 52"!) but be able to remove it and use it around the rest of the house/travel etc. So, when it is hooked up to the TV I would like to just leave it on so that I can wake it up with the remote or bluetooth mouse/keyboard. I have heard about heat with these units and wondering if anyone has problems leaving their laptop on all the time.

    I restarted my MBP for the first time in weeks today, it seems to do just fine. However, I am constantly using CS2 and some other rosetta apps., which seem to be causing some strange issues with cache. I have to delete my caches once a week or so to keep everything running snappy and clean.

    My MacBook Pro is on 24/7 and it's fine, the only time I restart is when software updates require a restart. I use SMCfancontrol (1.2.3) and set the fan speeds to 4000 RPM and it is still very quiet but it keeps it cool when I'm only listening to music and doing some web browsing. When I start encoding files and have that going for several hours it gets quite hot and gets to about 170F, I've had it running at that temperature for over 8 hours straight before and it's still fine and I didn't have any problems from doing that.

    I leave mine on 24/7. No problems here, even running Visual Studio via Parallels and downloading with 20 open connections on Usenet.

    If you are asking I would recommend downloading a helper app instead of manually doing it. Cacheout X is a great easy to use cache romoval tool that only removes caches.

    Also try booting into single user mode (command s at start up) type in "exit" followed by the return key. Once the computer boots back into OS X restart the computer.

    Applejack is another app, that is run out of single user mode. Applejack works great, has a bit of an advanced user stamp on it because it has no GUI. However, it is well worth learning to use as it works wonders.

    Count me in as another one whose MBP is always on, albeit sleeping while I am at work. While on and in use, I've never had it get overly hot. I can't say the same for my PB 12" which, in some rae instances, would get stupid hot.

    I've had many things running silmutaneously and so far, so good. *knock on everything*

    i've left mine on over night, etc.

    one or two times i woke up to find my computer unresponsive. The HD was powered down and it beached balled...after moving the mouse and pressing keys he HD did not power up. I just restarted it and it was okay. Wonder what happened...

    My MBP gets ALOT of usage per day. Sometimes it gets 12 hours or use between using it to study, slack, plug it to my TV to watch and leave it on to download. It gets hot at times but I don't care since it's not on my lap while I'm doing intensive things with it. I have rarely had any problems with it, none in the past 3 months.

    To anyone who makes the mistake of using cache cleaners.....,00.shtml

    While this program is the worst of the lot, I have very low expectations from the rest of the shovelware community.

    Lets first get something straight.... there are ppl with CD and C2D. Apparently the CD (which i have) gets really hot just for simple, normal use and i really dont like it. The C2D apparently does not get as hot. But still gets hot when doing intense stuff. but normal use ... the C2D should stay cooler (correct me if im wrong).

    Also there were some issues with the CD earlier with thermal paste etc.. which im sure many of you know about already... And the C2D had a redesigned heat removal system making it more effective.

    I suppose that the MBP in general is pretty lousy with heat dissipation. My old PB was awesome... never got hot at all... ever lol.... (except with video editing). oh well... lets hope that the next mbp will be better.

    I had a CD model, and upgraded to the C2D the day it came out. The C2D definitely is cooler.

    I leave mine on all the time, pretty much been on since I got ill effects.
