I'm running Folding@Home SMP version on a new Thinkpad X220 laptop since I can't use it for daily development but find it useful to run a MySQL VM. Since its just sitting there I've been running Folding@Home for the past 4 days (mostly) straight.
However I'm starting to get nervous. I recently needed to recharge the battery but now the fan has kicked in. Getting worried, I installed lm_sensors
in Fedora Linux and checked to see where I'm at (I added the degrees in celcius for those of you in other parts of the world)
acpitz-virtual-0
Adapter: Virtual device
temp1: +197.6 F (crit = +210.2°F) - +92.0°C (crit = +99.0°C)
thinkpad-isa-0000
Adapter: ISA adapter
fan1: 4627 RPM
coretemp-isa-0000
Adapter: ISA adapter
Core 0: +199.4°F (high = +186.8°F, crit = +212.0°F) - +92.0°C (high = +86.0°C, crit = +100.0°C)
coretemp-isa-0002
Adapter: ISA adapter
Core 1: +195.8°F (high = +186.8°F, crit = +212.0°F) - +91.0°C (high = +86.0°C, crit = +100.0°C)
Yikes, those tempratures don't seem like something I should be running the laptop all the time, but I'm not sure.
Do I risk damaging the laptop with tempratures that high (both with and without the battery)? Can I run Folding@Home for long periods?
I've had similar problems on a Thinkpad tablet. On my system, it will shut down spontaneously when it gets to 100°C. – Mechanical snail – 2011-08-03T23:17:47.590
In general, high temperatures will reduce battery life, but obviously only if the battery itself gets hot (rather than just the CPU). – Mechanical snail – 2011-08-03T23:19:08.073
