Inspiron 1545 fan

Hi, I have just received my new 1545 and installed Intrepid on it (not insterested in vista at all) and to my surprise i noticed the fan stays completely off until the temperature reaches around 65C and then stops when it drops to around 55C (i think). I dont know if this is normal; but it worries me quite a bit that the temperature always goes up and down because of the bursts of the fan (as opposed to a constant low level spin of the fan). I tried i8k; the fan speeds are displayed... but adjusting fan speeds fail no matter what... at this point i have a few options: - ask some Dell engineer if such fan behaviour and system temperature is normal and trust him/her - wait for some hypothetical BIOS update to allow fan control (either thru i8k or BIOS settings) - wait for some hypothetical patch to i8k - pray the laptop doesnt burn itself to death due to a sily BIOS/i8k problem - send back the unit as faulty - buy a laptop cooler (urgh... especially on a new machine) any ideas ?
