Asus n71vn overheating on games

I have a problem about my cpu overheating when I have any games on. On normal use my cpu is about 60*C but when I run any game (that uses lot of cpu) I have something like that:
-Fan works slowly till reaching 98*C
-At 98*C Fan changes to fast speed
-At 100*C Computer have a 5 second freeze (cpu disabled?) and fan slows down
-After 5 seconds fan goes back on slow speed, cpu on 90*C and temperature goes up (cycle starts from begin).

How can I change it so fan goes on full speed on lower temperature?
Sensors output (after 5 minutes of playing a game):

[hubertnnn@asus ~]$ sensors
acpitz-virtual-0
Adapter: Virtual device
temp1:        +98.0°C  (crit = +105.0°C)

coretemp-isa-0000
Adapter: ISA adapter
Core 0:       +91.0°C  (high = +105.0°C, crit = +105.0°C)
Core 1:       +90.0°C  (high = +105.0°C, crit = +105.0°C)

I think Its becouse of that high=105. Can I change this?

Re: Asus n71vn overheating on games

If you've ever have ran this laptop on windows? If you have, have you had the the same issue?. My best educated guess is it would be a glitch in the BIOS or a problem with acpi. I would start by looking into weather this is common on this laptop in linux or in windows, If your BIOS is outdated or users reported problems with it, or looking to see if there are any acpi related problems  with your specific laptop, and if you can change the fan speed with one of the acpi fan tools in the aur . In the mean time. Don't play games. you could be doing damage to your system

On windows it also was hot but not that hot and fan was working a bit faster (I feeled the air stream stronger than now). As I said, I think It tries to keep cpu on higher temperature than it shuld, for example, If I am not gaming at about 70*C fan shuts down completely (or at least slows that I dont hear it at all).

Re: Asus n71vn overheating on games

my best guess would be an acpi problem. I'd go from there

Re: Asus n71vn overheating on games

I think I found half source of my problem. If I read this document correctly (http://www.mjmwired.net/kernel/Document … ernors.txt) OnDemand governor choose between my minimum and maximum speed depending on cpu usage. Minimum (800Mhz) is too slow for games so when gaming I have constantly max power (2.53Ghz). I changed to conservative and now games use 1.6Ghz and temperature stays at about 80*C (a bit better) but It looks like it never uses max power, or at least I havent seen it switching to 2.53Ghz.
Is this configuration ok?:
