hi my newly assembled pc which has a 2.4ghz processor on a asus p4pe m/b 512 ram ddr 333 and 3 optical drives and one hhd etc the temp goes up 62 c in matter of minutes i have read that the heat sensors may be reporting the wrong temp any there is no danger on the cpu since the heat sink is normal hot ....but i wanted to ask how disable the beepings alerts which bucks me :(  . can any one recommend me a 6000 rmp fan

what is making the beeping? do you have a program running in the background to monitor temps? if so, change the options so that no warning is issued
why do you need a 6000 rpm fan? is the program beeping because the fan is under 6000 rpms? you should be able to change that too...

i had a program but i unistalled it but the board makes those warnibg beeps notifying me of overheating is there an option to disable this monitoring from the bios. in the bios the temp is 52-60 celcius :( is the sensors giving me the wrong temp

It sounds like you might have a poor mating between CPU and Heatsink.  I would suggest you shut down, remove the heatsink clean everything up nice and shiny with some alcohol.  Check the thermal pad on the heatsink.  If it's damaged, even a little bit, get rid of it and put in thermal grease in it's place.  You can get thermal grease at Radio Shack and most computer stores have it.
 
The instructions for applying thermal grease are here:
<A HREF="http://www.arcticsilver.com/arctic_silver_instructions.htm" target="_new">http://www.arcticsilver.com/arctic_silver_instructions.htm</A>
(It doesn't matter what brand you use, the process is the same.)
 
When reinstalling the heatsink, be very certain all clips are firmly seated in the motherboard side of the assembly.  A loose clip will cause the heatsink to sit askew.
 
Also... some, not all, Intel heatsinks have a plastic cover over the thermal pad.  This will of course cause heat problems.  Check to see if it's been removed (if it was there in the first place).
 
Finally... Whatever you do don't just go turning off the temperature warnings as someone else suggested.  It's telling you there's a small problem before you have a really big problem.  The goal here is to fix the problem... not ignore it.

It's unlikely the sensors are misreading the temperature.  Intel sensors are pretty accurate as a rule.  
 
As I said in my other message, I stronly advise against just turning those warnings off or adjusting the thresholds.  The result could be a cooked motherboard or processor... which is exactly what the temperature warning is trying to help you avoid.

but i undertstand that this board might be having some problems from different forums i have read.... they say it might give you wrong readings regarding the sensors so when it gave me a warning that it has reached high temp i touched the sink and it was not that hot it just warm i think i was just maybe 40-45 celcius i can keep my hand on it for a while and its not thet hot ...why is that showing me a 62c but it just felt warm and not that hot .

Cooling systems aren't about the temperature of the heatsink... they are about the temperature of the CPU.  That is what the sensors are reading.
 
The idea behind the heatsink is to gather thermal energy from the CPU and disperse it over as wide an area as possible... thus keeping the CPU cooler. The fan's job is to take the heat off the heatsink and spread it over an even wider area: into the air. The heatsink will warm up a little in normal use, afterall the heat is travelling through it on it's way into thin air. The fan is cooling the sink, so it's not going to get as hot as the CPU.
 
When you get high CPU temperatures it means one of two things:
1) The heatsink is not doing it's job.
2) The temperature is being misreported.
 
Do you really want to take the risk of it being #1?  
No you don't... that's how things get burnt out.  You want to be sure the heatsink is doing it's job first... then you can move on to suspecting the sensors or BIOS (#2) when you are <i>absolutely certain</i> the CPU is not actually overheating.
 
It's just common sense to clear up the worst possible outcome first.  That's how you keep your system from failing.  As a tech who works on this stuff all the time, that's what I'd be doing... making sure it's not the most disastrous possibility before I moved on to some crap about bad readings I'd read in an online forum. I would be <i>extremely reluctant</i> to just go adjusting the warning thresholds because it is very possible I'd be putting the machine at increased risk of failure.
 
What does it hurt to lift up that heatsink, clean the daylights out of it, check the thermal interface, maybe put in some thermal grease and clip it back into place?  You might end up accomplishing nothing... but at least you eliminate the most disastrous possibility before you move on to other things.
 
A little common sense prevention can go a long long way...

hi, so u suggest that i open the sink and apply thermal paste... ? i wanted to know i should apply the paste on the skin or on both ? a bit or toomuch ? and about the temp i will see when it reaches 62c i will shutdown the pc open the sink and see the heat of the processor what do u think ?if i fine the processor heat normal what does that mean  a misreading from the sensor or u think i should update the bios ?(its the default 1002 when the m/b came )
or it can be my vga i keep my tnt2 card is that ok ? man i don't know what to do :( anyway thanks let 1st work on the sink then we can check the other thinks ... but the way what king if fan is good a 4000rpm or more ? any i wanted to change the sink in the first place ...

Ok... I am suggesting basic troubleshooting techniques...  
(please read carefully)
 
Disconnect your computer, put it on it's side on a table, open the case, carefully take off the heatsink...  
 
CLEAN any dust from the heatsink and fan.
 
CHECK the bottom of the heatsink.  Some, not all, Intel coolers are provided with a plastic cover on the bottom of the heatsink to protect it during shipping.  This must be removed for the cooler to work correctly.
 
CLEAN the CPU with isopropal alcohol and a soft cloth... "hospital clean".  
 
CLEAN the thermal pad with a soft cloth.  No alcohol since that might damage the thermal materials.
 
INSPECT the thermal pad on the heatsink for damage or foreign materials. Even something as inoccuous as a hair laying in there can affect the heatsink's ability to cool the CPU.
 
<b>IF</b> and only <b>IF</b> the thermal pad is damaged you need to replace it with thermal grease... Remove the pad from the heatsink exposing the bare metal underneath and clean that with alcohol. Then follow the instructions in this link: <A HREF="http://www.arcticsilver.com/arctic_silver_instructions.htm" target="_new">http://www.arcticsilver.com/arctic_silver_instructions.htm</A> to apply the thermal grease.
 
<b>IF</b> the thermal pad is smooth, clean and not damaged, just carefully put it all back together being very sure the heatsink is sitting level and the clips are done up correctly. Intel's instructions for heatsink installation are here: <A HREF="http://ftp://download.intel.com/design/Pentium4/guides/29859001.pdf" target="_new">http://ftp://download.intel.com/design/Pentium4/guides/29859001.pdf</A>
 
 
The purpose of this exercise is to discover if there is a problem with the heatsink removing heat from the CPU and to ensure that, once reassembled, it's all in good order.
 
The next step would be to test the machine with the newly cleaned and re-installed heatsink.  If you still have high temperatures, your problem most likely lies elsewhere, in which case there are a number of things still to be checked...
 
1) Is the CORE voltage set too high in your bios?
2) Is the fan on the heastsink spinning at the right speed?
3) Are you running something that produces constant 100% CPU usage?
4) Are your case fans moving air smoothly through the case?
5) Is the system (case) temperature high?
6) Are your power supply voltages right?
7) etc.
 
My point --and the reason I jumped into this-- was that the absolute last thing you want to do is disable a safety feature.

i will  check the heat skin in the morning ...so i will just answer you regarding the other things  
1- its set t0 1.52 v  
2-2230 rpm
3- no anyprocess will do this especially caputering and while converting divx movies
4-well it should the temp is not high in the case
5-no its ok  
6-its 300w 230 volts

I am running P4-2.53Ghz with a MSI 845PE2 MB.  The monitoring software shows 49.1deg C to 53deg C on average.  However, the temperature shot up to 60deg C when I was transfering my video on the harddisk to the CD writer once.  Is that a problem?

hi guys i sloved my problem :)(almost) . the beeping that i was geeting is gone :)... the problem was the power supply when ever i do a heavy task i used to get the beeps .. now after i kept a 400w powesupply from the old 300w powersupply it has sloved my problem :) . i also got a new sink a 4000rpm i also helped to reduces the temp by few degrees :) . thank all of you for your help . oh buy the way i just got my msi geforce 4 mx 440 8x and i wanted to know how far was the card overclocked without any problems?
