My laptop is Acer Aspire 4741G:
- CPU: Intel Core i5 460M(2,53GHz)
- 6 Gb RAM (Kingston DDR3 2gb+4gb)
- 320 Gb HDD
- NVIDIA Ge Force GT 420M (1 Gb)
Tried Ubuntu 10.04, 10.10, 11.10, 12.04, here are the results:
10.04 - no overheat, usual T=50-55C - only troubles in installing Video drivers for GT420M
10.10 - no overheat, usual T=50-55C - only troubles in installing Video drivers for GT420M
11.10 - proprietary drivers for video are just fine, but overheats(T=60-70 C)
12.04 - proprietary drivers for video are just fine, but overheats(T=60-70 C)
for 11.* & 12.04 - when just installed - temperature is almost normal(idle t=55-60, when watching video's t=60-65 C).
After about 1-2 days(installed: Chromium browser, Mozilla Thunderbird, PCSX-R, qBittorrent, Skype, SMPlayer.) the temperature went up till: idle t=65-70C, working t=70-80C(Note-the temperature goes up after 1-5 minutes after booting computer, and i don't start such programs, as qbittorrent, Skype, SMPlayer, PCSX-r etc).
Tried to re-install video drivers, no luck, temperatures are all the same: idle t=65-70C, working t=70-80C(also in idle found, that some of the screenlets are lagging, & videos have mistiming glitches, which could be solved only by restarting the application). P.S.: Needless to say, that laptop is always in my hands,or on table, & there is always 1-2 inches gap between bottom of laptop, & any surfaces.
P.P.S.: I have Windows 7 dual boot on this laptop & temperatures in Windows are MUCH different(idle= 45-55 C, working= 60-65C)
