Hot Mac

[sawman]

My macbook has started running hot for the last day or so - with the fan on almost continuously.

I'm down to my last 8GB of disk space, is this related or have I got some other issues

Advice please

Are the vents clear at the back? I know if i use my one in bed the covers block the vent which makes it run a little warm.
Also is it on charge or downloading this also tends to make them warm.

even using it on the kitchen table the fans are kicking in after 3-5 mins, cpu temp is 75-80 degrees.

normally its running for a good while before getting to that temp vents appear to be clear

Sounds like junk that gets built up in the vents over time.

You could try compressed air otherwise it may need a strip down to check the fans are working correctly and maybe it needs a clean.

Unless you're an I.T. person I'd suggest seeking some help because as you very well know a mbp is a expensive bit of kit.

Check to see whether you've got any processes running flat out first... a MBP will happily run its CPUs at 70-80˚C and fans at full pelt if you've got both cores loaded 100%.

Use the Activity Monitor, or top in the unix terminal if you know unix, and see whether you've got things running that you didn't expect.

If the machine is idle, and the CPUs aren't working hard, and you're still getting the high temperatures and fan, then go with the 'clean it out' approach. But check first that this isn't just 'normal' operation because something has got borked and is running at 100% CPU.

and i thought this thread was for a Mac that had 'fell off the back of a lorry'

Cheers Cyberface, my vodaphone dongle software was hogging 75% CPU - sorted it out, all nice and cool (and quiet)now
