Fan speed does increase for a reason.....heat. Check you BIOS settings and verify that the CPU temp is not getting too high. Desktop computers are dirt magnets. It is common for the CPU heatsink to get clogged with dust and dirt. This will reduce cooling and increase heat, eventually to the point that the fan will speed up. Get some electronic duster (canned air) and blow out the fins on the CPU heatsink. DO NOT remove the heatsink from the CPU. There is a special compound that is on the heatsink surface that allows proper heat transfer from the CPU. Removing the heatsink means that this compound is disturbed and would need replaced. Most users do not have this compound and thus should not remove the heatsink to clean. If the heatsink is so clogged that you cannot get the dirt out with canned air, you may be able to remove the fan from the heatsink, depending on the fan/heatsink design. Then you can use a brush to get into the fins to clean them.
I have found that if the room temperature near the computer is too high creates a problem. If the processor is being used at a high rate that will influence the temp sensors and cause the fan to run at the "speed" you hear. (It is on all the time, just different speeds). Other heat producers may not have clean fans or fins, for example display adaptor or power supply. or but unlikely, the
cpu fan interface is not well seated or no heat transfer grease. You didn't change the processor did you?
BIOS speaker is broken, and you hear high pitched beeps? Hmmmmm,..........
CPU temperature in normal............ What is the CPU, and what is the temp? Hey, I gotta know so we are on the same page here, lol!
Me? Those repeated high pitch BIOS Beep Codes indicate a CPU problem. I would remove the Heatsink/Fan combo, and replace the Thermal Paste. (Following Anti-Static Precautions, and cleaning the CPU, and Heatsink, of course)
Also make sure the Heatsink is sitting flat. Yes, I know what you stated about Speecy, and Core Temp, but I would try it anyway.
Still no? CPU is sounding Taps, and telling you goodbye.
so your reported figures show that the unit is operating as planned
the closer to ambient temp the shorter it runs for
the further away from ambient temp the longer it runs for
when the desired temp is reached , the compressor will stop but the fan will continue to run to circulate air past the thermostat so that it will switch back on when the room temp reaches too high temp
and that is why it is recommended to set the temp at 25 C as that is the most economical temp to run it at
there is no such thing
but there is if you told the ambient temp there and did not
PC can be in 0F to 95F , environments.
we can not guess where you are or the temp there. can we.
this is called normal temperature RISE over ambients.
and what the PC is doing now, idle or gaming or what.?
HD0 138 degrees Farneight and Temp1 is 149F.
a goal is 50C or less. your at 65C
65C is ok gaming, ,
all PC's on earth last longer cool that is a fact.
and 90C the CPU shuts down to keep from blowing up.
50C is 25c rise over 25C ambient. see that?
if in a Cabana at 120F ,48c the temps go wild and it 90C and the PC self shuts down. fans screaming
are you fans screaming?
BIOS runs the fans and all fan paths must be kept lint free.
at 25c room 50 is not bad.
my gaming PC runs 30C on HDD 1,2,3,
and GPU is.32C
and CPU is cores 37C as I type now. (i have 4 fans in sys)
My PSU (DPS) is 31C
laptops run hotter, and is mostly caused by users crying like babies
on fan noise. so the maker underclocks the PC to cool it
I run fan over-rides on mine to run 25% more fan RPM to keep it cooler. and last longer./
50C is not bad or wrong, NO CPU runs at 25C, ever, to do work(means clocking it) burns power in the CMOS logic.
just like a car but way worse there. no room temp super conductors yet, my 1/2 joking
a desktop works 10x better and can be actually made better easy
Yes.... over heating can and will cause a system shutdown..
Download and install speedfan ( http://www.almico.com/sfdownload.php ) It will most likely tell you how hot things are really getting......
Depending on what cpu you have, you may have a thermal paste problem, you may need to remove the heatsink and re-apply heatsink thermal paste to the bottom of the heatsink and reseat ontop of the cpu. This will void any warranty if you PC still has any left.
Generally you will see core temps around 50C with a stock fan and no overclocking, that is if you run fully loaded 100% cpu usage. But this is all highly dependent on what type of cooling you have. A program like GIMPS Prime 95 will test your processor. The max temp for most of the Pentium 4 series is 85C, but to know all the details we need to know which core you have. Wikipedia would help you determine which core you have, or you can download a program that will tell you. http://en.wikipedia.org/wiki/Pentium_4
CPU usage generally depends upon what application(s) you are running. There are some apps that barely utilize the cpu, and there are others that are resource hogs that peg the CPU near 100%.
CPU temperature will also vary, depending on the load, and numerous other factors. For example, the ambient temp will affect the CPU temp - when it's cool in the room, the CPU temp will not be as high as if the room temp is warm/hot. Other factors include the type of HSF, the number of fans in the system, and the case itself, as some are better at dissipating heat than others.
So, to give you a better idea of what temp is normal for your setup we'd need much more info about the system. But for reference, 40 celcius is a pretty good CPU temp, particularly if that is under load.
