    Hi there, i just got a 'nearly new' 15" 2.16Ghz Core Duo MBP from work. It's a great machine, i upgraded from a Powerbook G4 1.25GHz so it's a massive jump in portable power.

    It also has a 100GB 7200rpm HD inside.

    I've noticed that it's not that quiet, though, and the fans constantly spin. It's quite hot. On the PB, the fans would be off until you ran the CPU at 100% (or near) for a while, then the fan would come on. However the fans are always on here. When pretty much idle, they were both @ around 1000rpm, like now the mbp is sitting on a table with quite a few apps open but not much going on other than itunes and me typing this message. Just a second ago though, my CPU temp in istat was at 80+

    There's a pic of my istat info attached.

    Does this look normal? Or is my machine running particularly hot? I guess the core 2 duos run cooler. Plus i have the 7200rpm drive.

    Thanks - i tried a search but it was hard to find info on this specifically.

    seems fine to me albeit looking a bit on the "hotter" side

    A little bit hotter than usual considering that you're not, at this time, doing anything intensive (8% CPU Usage).

    Perhaps it's down to the 7200rpm drive? In fact maybe the whirring i'm hearing is the HD and not the fans... it is coming from the left hand side of the laptop, which is the hotter side... i assumed that was where the cpu's were though

    Wow, 48C? What component/part was that temperature for?

    Thanks

    Interesting. My MBP 2.16 C2D is always around 1999rpm and with regular use varies from 48-53C. Do something challenging and it'll go to 73C before the fans even pick up...

    Hi - how long have your mbp's been running?

    I just turned mine on 5 mins ago and it's running cool (attached), but i expect it to rise...

    When i took the pic earlier, it had been on but pretty much idle all night and all day

    What you have seems to be normal. Core Duo runs hotter than Core 2 Duo chips.

    Not sure if anyone has recommended this to you yet, or if you are familiar with it, but you should download and install Fan Control.

    http://www.lobotomo.com/products/FanControl/

    You can set the base speed of your fans, which is usually lower than OSX will run them, and you can set it to your ideal temperature range and it will control the fans accordingly. Keeps mine quiet most of the time and cooler when I use intensive programs.

    My MBP, same model as the OP, could be used as a grill surface for a short-order cook. I use smcFanControl to boost the fans to 2800 RPM when running on battery, 3200 RPM when running on AC and 4500 RPM when the charging the battery (with the machine on, of course).

    My wife's MacBook, on the other hand, stays nice and cool.

    Does anyone know if my mbp will get quieter if i put arctic silver on the cpu?

    I have to take the machine apart to replace the screen bezel - does anyone know if it will drop below around 1000rpm per fan when doing normal web browsing etc etc?

    Or is 1000 as low as it'll go?

    Here's mine, 2.16ghz Core Duo. Makes virtually no noise at all.

    I've owned the same machine (2.16 CD, 7200rpm HD, 2GB) for over two years, since it first came out. It's hot, no two ways about it. Like another poster, I've used Fan Control (the prefpane, not the app) to boost my fan settings. Fan Control is temperature based, not rpm based, but at idle my fans are usually between 3000 and 3500 rpm. It definitely makes noticeable fan noise, but it's far more comfortable for me to have a cool case and a little more noise.

    Temps are usually 40 C at idle and can climb to 90 C under load. Despite the high temps the machine has been rock solid.

    If you try to keep the fans from running you'll just fry the processor. :eek:
