    Hi, I havn't been here in a while, but when I started having problems with my computer the first place I thought of was the place where I've seen some of the best pc advice on the internet.

    When I got my x2 3800+ it had that grey stuff that melts when the processor heats up on it. I ended up heating it up and wiping it off so I could take the processor off when it was cold. At that point I had some clear greasy electrically conductive "thermal interface" that I used.
    After wiping the heatsink and heatspreader, I put some on the heat sink wiped it off, then spread a small amount over the heatspreader with a credit card. The processer overheated and rebooted as soon as windows started. I tried again with less grease and eventually though the temperatures seemed kind of high, the computer worked and I left it alone.

    Recently my northbridge died when the fan failed so I just wiped the old grease off thinking It should be easy to get another giant tube and replace it to prevent air bubbles and whatever might contaminate it while it was disconnected. All I could find locally was Arctic Silver's ceramique. I tried spreading it with a credit card and it was so thick I couldn't get it smooth. So after reading the instructions on their website I cleaned it as thoroughly as possible. The first time with 70% isopropyl alcohol, the second time with denatured alcohol. Then I rubbed some arctic silver into the heat sink, wiped it off and put a rice grain sized amount on the middle of the heat spreader twisted it and clamped it down.

    I've done this several times these are roughly average for temperatures I get with speedfan when the computer is idle:

    "cpu": about 1 degree below ambient near 32 degrees celsius

    "core": maybe 5 to ten degrees above cpu

    "remote":~74 degrees

    I also noticed the hard drives are hot @ about 45 degrees



    Remote seems to correlate best with the temperatures I get from the bios and if I try to use the pc it still gets hot enough to spontaniously reboot.

    I also noticed that the fans speed up when the processor load increases, but not nearly soon enough to keep it at a good temperature.

    The other problem is that this:
    http://www.geeks.com/details.asp?InvtId=A8N-LA-WB
    motherboard was apparently manufactured for compaq and didn't come with a backplate. Out of frustration I covered the holes with tape.

    I can think of a few things that could effect the temperature, but none of them seem to me to be capable of having a big enough effect to cause that kind of problem.

    The difference between cpu and remote suggests to me that the heat sink isn't conducting well enough. Which seems to mean that I'm either doing something wrong, I need something better to clean it with, it is permanently contaminated with the waxy interface that came with the processor.

    The ceramique seems incredibly thick and chunky, but it is supposed to be thicker than average.

    The high hard drive temperatures make me think there could be a problem with the case.

    The low fan speeds and disparity between cpu and remote make me think that possibly there could be a problem with the sensors or cool and quiet.

    I don't remember ever haveing so many problems with something that should be so straightforeward.

    Hopefully someone can help

    It may be me but if the CPU temp is 32 how much cooler do you want it? Thats pretty damn good. 1 degree below ambient isn't bad at all. I am a bit confused by what you said that you "rubbed it in" to your heatsink?

    What do you mean "remote"

    As far as the fan speeds go You can turn off the Auto sensing for the fans in the Bios and just have them run full speed all the time.

    Another thing to explore is to make sure the CPU cooler is making full contact with the chip. I know it sounds dumb but really check closely and you can add a bit more thermal compound than a rice grain, it's not going to kill anyone.

    The HDD would be the air flow in your case as I initially think that may be the cause of everything getting hot. What kind of case it is how many fans...

    Not "bad at all"?
    Try "impossible".

    @Lizardcreature...I use Ceramique on everything because it's less conductive (and I'm a slob) and find that it works just fine.
    Your Speedfan temp of 5-10c over ambient seems OK as well.

    Pull the sidepanels off the case and see what the HDD temps do.
    Presumably they will fall and you'll know you have substandard airflow around the drive cage.
    This should be fixed somehow.

    The instruction at arcticsilver.com say to apply some grease to the heat sink and press it in to fill the microscopic valleys in the heatsink that can harbor air pockets, then to wipe it off again.

    I'm not where the cpu temp is taken, but I don't see how it can be cooler than ambient, if it means anything my guess is that it means that the heat is not being conducted out of the cpu core well, core isn't right either, because when I compare that number to what I see in the bios it is a lot lower than the temperatures of ~80 degrees celsius that I see there. If anything in that list accurately reflects the cpu core temperature I'm prettty sure it must be remote, though I have no idea what "remote" is(could it be the sensor on the processor itself?). I guess I was thinking that if the speedfan temps were useless you could just ignore them.

    Unfortunately my motherboard and bios were manufactured for compaq based on previous experiance I felt really lucky to be able to change the date.

    Iv'e experimented with different amounts of thermal grease and nothing seems to work.
    thanks though

    I think I forgot to mention that if I go straight to the bios the temperatures climb steadily untill the pc spontaniously shuts itself off. I'm pretty sure the speedfan results for core are inacurate, though I'm not sure why. I'll try the thing with the case to see what is wrong with that, but I don't think it's related to the computer randomly shutting itself off unless that could be enought to raise the temperature of the cpu core by that much?

    I have never read the arctic silver site. Thus I have never done that. Eh you learn something every day right. Now I gotta take my rig apart

    What CPU cooler are you using? Again I would think the thing isn't sitting on the chip correctly maybe try re-seating the chip and the CPU cooler.and check up really close for any spaces between the copper/aluminum bottom and the chip.

    I reseated the heatsink. I can't see how it's possible for the processor and the heatsink to be misaligned, but with the backplate I can't see anything anyway. Now though, I think I must have trapped some air or something, because now it seems to start near 60 degrees and climb steadily. Nothing seems to change if I take the side panels off. The odd thing is that the fan speed climbs steadily with the temperature. Why would the fan speed stay at a speed that allows the temperature to very slowly and steadily climb constantly. ???

    "Trapping air" is not really possible but improperly seating the heatsink is and that's what I suspect must be going on.
    I'd remove the motherboard from the case so you can check if the sink isn't maybe hitting some component around the socket.

    Thanks for the help. I still can't see what is wrong.

    My retention frame and socket look like the one on page 16 of this manual:
    http://www.amd.com/us-en/assets/cont...docs/31684.pdf
    neither the frame, nor anything inside it seem to be higher than the processor when it is installed. The frame was installed at the factory and I didn't unscrew it because it seemed tight and flush and that would entail removing the motherboard. When the processor is clipped, but not locked with the arm it is capable of moving slightly and i can feel it sliding over the grease. Once it's locked it's immobile. If I take it off the greased is pressed into a circle that almost reaches the edges of the heat spreader.
    The only thing I noticed that I think could possibly affect the alignment are some scratches where the edges of the heat spreader contact the heat sink, and a small misalignment of the clip once it's locked.
    The clip starts centered in the middle of the heat sink and once it is locket it is pressed against one side.

    I can take the motherboard out, but there aren't any components that are higher than the socket.

    Wow this sure does seem odd. scratches and this fear of trapped air need to be ruled out man. Unless you have a gigantic bubble in there leaving the chip without thermal paste I can't see this even being a remote possibility. Do you have another set of clips for the heatsink or another CPU cooler handy? If so try those. Also check and see if the hooks on the clips are bent, not allowing the heatsink to rest flush.

    The only real thing that comes to mind now is maybe your board is somehow shorting and getting hot. When the Computer is running (carefully) feel around and feel if you can tell where the source of the heat is coming from.

    If you have a camera handy try taking some clear close up pics from a few different angles so maybe we can see what is going on.

    Lol, ok I thought I was being paranoid. I can't tell if the clips are bent but this is what it looks like:
    http://i279.photobucket.com/albums/k...on/before1.jpg
    http://i279.photobucket.com/albums/k...ion/during.jpg
    http://i279.photobucket.com/albums/k...1ion/after.jpg

    Moving the arm to the unlocked position causes the temperature to drop suddenly. locking it again causes it to jump.



    Does that mean the spring is bent?

    I'm a little paranoid about removing the only other cooler I have access to atm
