Why does my CPU rise rapidly in temperature?

    With all the problems and issues Im having with my PC, I also have a strange one, my CPU temperature. It keeps rising in temp, even with the fans on 100%. I really have no idea why. The thermal paste I used is an Artic Silver 5, I have my heatsink and CPU fan working properly, all PC case fans working just fine.

    I went into the BIOS to check the temp. At first it began at 69 C, then it just kept climing up a degree every 5 seconds. Even with the fans at 100%, it still kept climbing up to 80 C, which is unusual since I have no programs running, no graphics card installed or anything else. The cable management in my case is a bit messy but I've managed to hide most of the cables in the back and leave room for the fans to blow properly.

    Could it be a dust issue? I just checked inside and some dust has managed to accumulate. What can I do? It's very unusual for the CPU temp to rise above 80 C when it's not even running any program. Should I get a new heatsink, even though the one I have is an aftermarket Cooler Master? Or does the issue lie somewhere else?

    how's the temp when in windows? maybe it's sensing the temp wrong

    Got a window A/C unit in any room of your house?
    Set it way down low and put the comp in the room to cool way off. Turn the computer on when it's cold and see if the temperatures are appropriate/accurate.

    Odd... I downloaded SpeedFan and the temp Im reading from my CPU is 59 C while my motherboard is 35 C. I think you're right in that the BIOS is not reading the temp correctly.

    You might check for a BIOS update.

    I have an ASUS P7H55 M-Pro motherboard. Would I have to download and install some drivers?

    Replace your thermal paste on your CPU. You might have to much or to little or an uneven spread?

    I believe the thermal paste is fine. I only used a pea sized amount and placed the heatsink on top of it, with the thermal paste spreading out evenly. I don't think that's the problem.

    You really need to spread it across the entire CPU to get a realy good seat use a flat piece of plastic and spread it evenly. Just placeing a pea size dab in the centre does not gaurantee it will spread across the entire face of CPU.

    if you put termal & hsf properly it just fine
    most of time it BIOS fault to read temperature

    you can check it manually by touching the HSF
    if it's really hot then heatsink is hot.

    depends what cpu you use but 59C is quite hot for me (but it still in a safe zone)
    80C is not.

    if you don't understand how to update BIOS well, just leave it that way.
    unless you get problems (like restarting when you run any application, or BSOD) then you might need to learn how to flash your BIOS & check thermal paste on processor.

    i don't think its a driver problem...and i have heard sometimes(when wrongly arranged) many fans result in doing less than one would by itself...so may be u should check it out

    Sounds like bios, My bios reads 50 c for everything so i use core temp to keep track

    updating your bios shouldn't be hard. on my Biostar mobo I just put the bios file on a flash drive, in the root directory (i had tons of other stuff too on the drive, it didn't affect it) and pressed i think f12 as i was booting and it booted the bios updating thingy, i just selected the file and it updated. granted i had a few BSODs at first, that was alleviated when I reset my overclock

    You might wanna look into buying a liquid cooler , you will see about a 20c drop in the bios , I was having a problem like that myself

    Liquid cooling is only as good as the radiator in the loop. If the CPU is being insulated by the thermal paste (or if BIOS is misreading the core temp) then liquid cooling will not fix the problem.

    Also, adding liquid cooling to my rig only changed the core temp by 4-6 degrees, depending on how much I OCed it. Then again, I'm using an Antec 1200 case so I've got exceptional cooling across the system.

    The BIOS reads the temperature data from the same IC SpeedFan should actually read from. So it's probably SpeedFan at fault.

    Try using AIDA64 and check out the "Sensors" part of it.

    Anyway, thermal paste should be spread with a finger, leave an even small strate of it on the CPU and THEN push the heat sink on it.

    Just using a pea of it could also just mean that you're leaving a single glob at the center, which would actually hinder thermal dissipation.

    Important part: if you're using an Intel Core processor (socket 775 onwards) check out the heatsink "plug" things. They need to be pressed in a really specific way to let the CPU firmly contact with the heat-dissipating copper part underneath it. Most of the time it looks like it's correctly fitted, but instead it's not.

    Try wagglying the plug-things. If they do move even of a bit, then your heatsink is not correctly installed.

    By "plug things" I assume you mean the holes in the motherboard for the heatsink to mount on?

    For general information, the correct way to mount a heatsink has always been in a cross formation. Attach one corner first, then the opposite corner for even pressure on the CPU and thermal paste. Then finish the other two remaining corners and check to make sure the heatsink doesn't wobble.

    Just to make sure, I took out the heatsink to check the thermal paste and as Ive said, it was spread out pretty evenly. That cant be it. The heatsink is also firmly attached. I may have to add that this began recently, the BIOS reading high CPU temp. It used to read under 60 C
