Solved CPU Temperature 45 C When Idel state

May 4, 2012 at 05:10:44
Specs: Windows XP
Ok guys i have an AMD Sempron LE - 1100 running at 2.00 GHz

from 1 week i noticed my CPU temperature is 45 C and even increasing when idle state

any i got this temperature info from BIOS and not from any third-party application

my system temperature is 40c any Fan running at 3400 RPM

Is it normal or too high for CPU to get this much temperature at idle state?

if not than please assist me with som suggestions

Thanks!

ANYTIME your CPU heat sink is removed all of the old thermal compound must be removed and new thermal compound needs to be applied properly. Look here for the proper method for your CPU:
http://www.arcticsilver.com/methods...
On all motherboards the CPU fan port is near the CPU and is clearly marked "CPU Fan". Other fan ports are marked "SYS_FAN1" etc. or similar. The system or general fan ports can be 3 or 4 pin but the CPU fan port is 4 pin.
Making sure you have decent air intake low in the front and a good exhaust fan high in the rear will take care of your general heat build up which is keeping all of your components warm. If you take care of that and properly reset your heat sink then you should be much better in the temperature department. While it is great to have your CPU running in the low 30C's (or below), do not expect this under load or when overclocking though. Your CPU:

Shows you can run in the mid 50C's+ but lower is better.

You have to be a little bit crazy to keep you from going insane.

A 5C temp difference between the system & CPU is about right, but 40C is awfully high for a system temp. What is the avg room temp? How many case cooling fans do you have & how are they configured? If you can lower the system temp, the CPU temp will drop accordingly.

My room temperature is about 23 - 27 C most probabbly

I have two fans in CPU the one is in powerbox and another on CPU which is a AMD stock heat zinc...

and what do you mean by "How they are configured?"

and also my HDD temp. is also high i think, its 49 C

I downloaded a application and see what it tells

I can't view your photo. I'm at work & that site is blocked. But it doesn't sound like you have any cooling fans installed in your case. At minimum, there should be one exhaust fan in the rear. Does your case have a location for a fan to be installed?

Ok i got it,

i don't have any fan at back in my case but as my pc remains on 12 hr

so i removed the side case since 2 months as i doubted that my cpu may get too hot

and one day it will die and nowdays also side case always remains open i never

screw it up, so it should make a difference as the whole right part remains open

and cpu fan can absorb air from that side isn't it or i have to install a new fan?

And yes it seems like there are two slots at rear for installation of exaust fan don't

know perfectly but there are so many small holes together forming a round shape

For proper air flow install a rear fan 120mm if there is room or at least 80mm fan set to blow OUT (exhaust) of the case, Then make sure your front vents are not blocked by dust and if needed, use a can of compresses air to blow out dust from all internal parts. fans, heat sinks, vents, etc. Then close the side of your case so that the air can make a complete circuit in low in the front, over components, and out high up in the rear. The power supply's fan will help, but it is not enough by itself. Rear case vents are typically a rough circle of holes with either 4 or 8 holes in the corners for mounting either an 80mm fan or a choice of the 80mm or 120mm fan sizes. You should have a spare fan port on your motherboard, but if not then use an adapter to a Molex connector from your power supply (many fans include this), but attaching to the motherboard port is preferred.

Thanks a ton..!! to both of you.
There is no front vents in my case & it fully packed
but having 3 slots for DVD CD it will be ok if i remove one!!

One thing more that i just checked in my BIOS and its telling me that

SYSFAN @ 3244 RPM & CPUFAN @ 0 RPM WOW!! i mean how can this be

possible i can see my CPU fan is working fine and even how can a CPU can

survive without a fan & heat sinks? Is there something wrong with my BIOS or

sensor?Or CPUFAN stands for case fan & SYSFAN stands for the one on my processor?

If it is so than i doubt its showing 0 RPM coz' i don't have rear fan!!

Your 1100 is being slightly overclocked. If you are running a retail HS/fan that shouldn't be an issue.

Are you connecting the CPU fan to the CPU header?

The above evaluations are probably on target. Appears your entire system is running hot.

Most cases don't necessarily have a defined front opening for air but there should be a space between the front bezel and the flat metal on the fron of the case proper. Air can be pulled in there.

Do you have a top or bottom mounted power supply case?

If you say you don't have an additional case fan then CPUID may be picking up the wrong sensors. Check in the BIOS itself.

"from 1 week i noticed my CPU temperature is 45 C and even increasing when idle state

CPU temp at idle is a bit high but being the reading is from BIOS then the CPU is running at high and not being rolled back as it would be in Windows so that may be the cause.
Install Speedfan or HWMonitor and check the temps there at idle,light office type work (or browsing) and heavy work or gaming and see what your temps are overall.
A front fan is not needed but a clear path for air to enter in the front, preferably low down is required.
Your CPU fan could be plugged into the wrong port, the signal wire to the fan that allows the motherboard to read the RPM may have a break in it, or the motherboard's ability to sense the RPM may be damaged.
If the rear exhaust fan controls the temperatures then do not worry about the RPM since it is probably running at full RPM without sensing. If the fan is noisy, you may want to get a manual fan speed control for your system.

Yes @othehill i have a overclocked CPU but that should not make any more difference as there is a slight increase from 200-211 from bios

@Fingers now i'm worry about the sensors also, can you please markout the exact area in a picture of MB that where should be the 4pin pluged properly so that my MB can determine the RPMs.

And i purchased a rear fan from a website but it says it will be delivered with in 6-7 working days

I remember once before a month or two i opened my heat sink to clean it up as pc was shutting down automatically due to overheating of processor and after cleaning problem was solved!! but when i took the heat sink from the processor its obvious that the bond of thermal paste between the processor and heat sink is broken and i didn't applied a new one, may be thats why it remains hot,is it?
But what about the system my HDD is @ 45-50c and i think its too hot for HDD this is my new one because old one failed due to heat.

When playing games processor temperature increases by 6-10c it reaches to 51-52 never seen it to 55c, HDD reaches max to 50c

Your CPU fan should be connected to the header marked CPU fan. Should be located close to the CPU.
