I tried all versions of xedgers nvidia drivers 331, 340 and 346 and all of them get my machine temperature up to 95 and even more as sometimes my machine switches itself off and that happens even with almost no application running the other thing is when I try to run chrome my machine switches itself off right away after that I just noticed when I have nvidia driver active that gnome-keyring-daemon go nuts it uses up to 80% of my cpu and after a while all of my cores are used up to 100% That doesn't happen however when I have nouveau driver active instead the temperature is really normal and nothing of things stated above ever happens My OS is Linux mint Rebecca 17.1 and I've the latest version of kernel 3.16 This is the output of lspci -vnn | grep VGA -A 12 VGA compatible controller [0300]: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0126] (rev 09) (prog-if 00 [VGA controller]) Subsystem: Dell Device [1028:0491] Flags: bus master, fast devsel, latency 0, IRQ 53 Memory at d2400000 (64-bit, non-prefetchable) [size=4M] Memory at c0000000 (64-bit, prefetchable) [size=256M] I/O ports at 7000 [size=64] Expansion ROM at <unassigned> [disabled] Capabilities: [90] MSI: Enable+ Count=1/1 Maskable- 64bit- Capabilities: [d0] Power Management version 2 Capabilities: [a4] PCI Advanced Features Kernel driver in use: i915 00:16.0 Communication controller [0780]: Intel Corporation 6 Series/C200 Series Chipset Family MEI Controller #1 [8086:1c3a] (rev 04) -- 01:00.0 VGA compatible controller [0300]: NVIDIA Corporation GF116M [GeForce GT 555M/635M] [10de:124d] (rev a1) (prog-if 00 [VGA controller]) Subsystem: Dell GeForce GT 555M [1028:0491] Flags: bus master, fast devsel, latency 0, IRQ 54 Memory at d0000000 (32-bit, non-prefetchable) [size=32M] Memory at a0000000 (64-bit, prefetchable) [size=256M] Memory at b0000000 (64-bit, prefetchable) [size=64M] I/O ports at 6000 [size=128] Expansion ROM at d2000000 [disabled] [size=512K] Capabilities: [60] Power Management version 3 Capabilities: [68] MSI: Enable+ Count=1/1 Maskable- 64bit+ Capabilities: [78] Express Endpoint, MSI 00 Capabilities: [b4] Vendor Specific Information: Len=14 <?> Capabilities: [100] Virtual Channel
In general, temperature control in laptops is the responsibility of the system firmware rather than the graphics driver, because cooling is handled at a system level with interrelated cooling parts that combine cooling of the GPU, CPU, memory, and other components. It sounds like your laptop's cooling is inadequate to handle the heat generated by the GPU when it's running at full performance. I would recommend verifying that all of the fans are working and that the system is free of dust and other airflow obstructions.
I have tlp and indicator-cpufreq installed nothing helps my fans are running ok and as I stated when I have nouveau active the temperature is as low as 58 it only goes crazy whenever I activate nvidia driver May be it's a little bit better with 346 but the issue with chrome memory utilization still persists which is definitely something to do with the driver.
