I have just downloaded
iStat Menus which let's me know how hot the CPU, Hard Disk etc is getting.
I was wondering what sorts of temperatures you guys are seeing particularly with CPU and hard disk.
I have a 2nd Gen 2Ghz macbook with 2.5GB RAM
I'm using a new disk (200GB 16mb cache 7,200rpm Seagate) that is usually at 36 degrees.
Currently the macbook is under load and I have the following:
84 - CPU A
66 - Heatsink A
65 - Heatsink B
32 - Enclosure Bottom
56 - Northbridge 1
61 - Northbridge 2
47 - Membank A1
42 - Hard Disk
So what do you get? Will running for hours at 80+ degrees kill my CPU?
