cpu fan @ full speed all the time...!?

[mikeyagii]

hi, i have a little problem here, my cpu fan doesn't want to work at full speed all the time, its full speed 6500rpm and now its running 3183rpm and when the heat start to increase the fan follow until it reach 6500+rpm... regardless if i choose cool n quiet or user mode (full speed), i disabled cool n quiet but no luck...

so to make it work at full speed all the time (or at least i thought it will), i connected the fan directly to the power supply so it will be no more controlled by the motherboard but the problem remained the same, the fan start at 3183 and when the cpu heat-up it increases gradually to 6500rpm!!

what is controlling the fan speed this way!? does the fan itself has a built-in chip to control its speed!? i'm confused.

is there anyway to get my cpu fan works at full speed all time?

i want the fan to work this way to keep the CPU cooler at idle and also because i have overheating issues when at full load for hour or so and the summer is coming and this will make the temps even worse

i'm idle at 31C and on load it reaches 50C and this is in winter, what will happen in summer, where i live the summer weather is hot (at 36C - 45C) and in winter its (from -1C to 17C) so the cpu is already hot when the room temps are about 15C, what will happen in the summer, i assume that the cpu will be idle at 42C or so and on full load maybe 60C+ (my cpu can handle maximum of 55C then i will most probably burn according to TCaseMax v1.17)

so i want the fan work at full from minute one to keep things cooler

my spec. is in my sig. - the fan is the stock one that came with the cpu.

thanks a bunch in advance

your running a 1.8GHz cpu at 2.66GHz, thats quite an overclock there in your sig. congrats! have you backed off a bit on the voltage bringing it closer to 1.5v or less? the fan is a 3pin connector and you connected it directly to your power supply, so without me opening my case looking at my stock fan, i would say yes, it has a therm. mounted on the top near the fan's motor. blue'ish thingy. have you happened to dust out your case/the heatsink of the cooler? that can be a reason why the temp ends up so hot, you have 2 options after that, get water cooling, mod your fan somehow? or get another heatsink, one where you can controll the fan speed perhaps with a switch.

thanks mate

well yeah when i was overclocking i tried to keep the voltages down as possible but to reach the highest overclock possible, i had to set the voltage to 1.69v...

at 1.5v the cpu will not pass 2.46GHz

in fact, i didn't yet had the chance to clean the heat sink but i will soon, i took a look at it has some dust on it but no that much, i think this will get the cpu cooler by 1C or so, but i need something to cool it more

i've considered once water cooling but then i decided not to go for it cause its a bit hard to implement, expensive, a bit risky if a leak happened it will be a disaster and cause i didn't have a serious overheating issues

if i just could make the fan start at 6500rpm! i think this will keep it cool, but when it reach that rpm the cpu will be at almost 50C, this helps not to let the cpu go any higher but not good enough, the cpu should be maintained at lower temps to make live longer

thanks mate for your input...
