    Quick question: I keep getting very hot temperatures on my PC. CPU Temp's exceeding 80 deg. Celcius!! I need to redo the Arctic Silver 5. :confused:

    Also, do 64-bit machines run hotter than 32-bit ones? I don't quite remember 100%, but when I initially upgraded to Vista 64-bit, from Vista 32-bit, I think the temps increased consistently across the board by about 10-15 C's.

    Does that sound about right??

    Thanks all....:)

    Helps to mention which cpu;)
    If it's the one in your signature - that's HOT...Might want to re-do the thermal paste.

    Again, as Steve said ..................
    Assuming it's the CPU in your signature, 100° C is the uppermost limit so I'd put 80° C well within the danger zone. You can snoop around Intel for more specifics and I would certainly recommend you do so. It would probably be helpful to know which of the two T7600 Mobiles you are using and would be good to know the stepping when you embark on your own research. (what do you think, Pete?)

    Here's a little tidbit from Intel.
    Can we still assume this is your modded laptop with the upgraded CPU and upgraded GPU you've posted about on numerous occasions?

    :rolleyes:

    Yes, sir, it is the T7600. There are two versions of it? Well, it's the 64-bit capable Intel Core 2 Duo @ 2.33GHz, and I'm currently forcing it to 1GHz, due to the heating problems, until I get this resolved. Pathetic as it crazy slow at that rate. Maybe I didn't use enough silver paste last time????

    Check this out: So-called cooling pads, instead of the thousands of cooling solutions out there. What do you think???

    Whatever I decide on, I will replace the silver paste as well, of course.

    Again, do 64-bit machines run hotter than 32-bit ones? I don't quite remember 100%, but when I initially upgraded to Vista 64-bit, from Vista 32-bit, I think the temps increased consistently across the board by about 10-15 C's. You guys say 80C's is hot, and it's not that I disagree, but what would you think is a reasonable temperature for the unit I have in my sig. I have it forced to 1GHz, so it's "only" around 65C. Probably also too hot.

    Thanks again guys! :)

    I can't see why a 64 bit OS would run hotter than a 32 bit OS myself, but then someone will make it blindingly obvious. That is one reason why I hate laptops (they run far too hot, and you can't easily sort the cooling out) :p

    You are way more likely to use too much than not enough. And too much is really bad.

    I actually use a razor too spread paste, that way I get the excess off and its a really thin layer. Did you know Artic Silver actually performs better after a number of on/off cycles. Also, my T2250 runs at about 65C, which is normal for this processor

    80°C is pretty cool for that CPU :)

    Thermal Specification: 100°C

    Mobile CPUs always run much hotter then their desktop cousins.

    Code:
    Latitude D830, Intel Core 2 Duo T7300, 2.00GHz, 800Mhz 4M L2 Cache, Dual Core
    15.4 inch Wide Screen WXGA LCD
    2.0GB, DDR2-667 SDRAM, 2 DIMM
    256MB NVIDIA Quadro NVS 140M
    80GB Hard Drive 9.5MM 7200RPM
    At boot my laptop temps are:
    Core 0: 44 degrees
    Core 1: 44 degrees
    GPU: 48 degrees
    HD: 29 degrees

    After about an hour, those temps rise an average of 25 degrees each and level off.

    Core 0: 52°C - Max 63°C
    Core 1: 54°C - Max 66°C
    GPU: 64°C - Max 68°C
    HD: 41°C - Max 42°C

    Current ambient temp: 21°C

    What program do you use to find these out? :)

    Yea, well, I don't know about this 80C being "just fine" for a computer...any computer.

    I think I remember Vista x64 to be quite a bit hotter when I upgraded from Vista x86. I know and remember because I run PC Wizard and my problem is getting worse. Even at 1GHz, it is now consistently in the low 80's C. How much does the fan suffer as far as collecting dust from running my baby 24/7. Right now, 82C for both cores and CPU temp. CPU Voltage is @ 1.063, with only 35% load on each core. :(

    35% load on each core? What's running when the CPU performance is at 35% ? My CPU never reaches 35% unless an app is loading or I'm playing multimedia. When idle, it backs down to 0-1%.

    Tony, thanks, and yes, I was surprised, too, so I took a 2nd look. Both cores are down to anywhere between 1 and 4 percent once the 24 tabs I usually have open in FireFox 3.1 are taken down, the CPU follows suite as far as the load on each core. Duh me!

    Alright, Arctic Silver 5? Any silver paste? I want to take care of this today, and also clean the fan out. I remember when I first got the T7600 CPU, I asked where I could pick some up, and the answer was always Radio Shack from people over here?

    I was outside of the United States at the time, though, and ended up getting different silver paste from my dad's computer guy. Would BestBuy or Fry's (any fellow Californians/West Coast folks here??) have it?

    It would be great if there was an instructional video or pictures, as all explanations have always said "don't put too much, and not too little ". That's all relative, so I obviously did it wrong, if I already need a fresh layer of paste since installing the CPU.

    Tony, thanks again for making me look twice. Looks like my CPU cores are fine when idle. I am giving this baby to my girlfriend, and want her to have a system where she doesn't have to mess around with making sure to take it down to 1GHz when the temps no longer allow for anything higher than that. What a joke. lol...

    Thanks again! :)

    Thank you! :D

    Thanks Tony. I got the AS5, and everything else in the video!

    Alright, It's 2:08am, I'm dead tired as, and I got Scarface on. I'm going in! :D:D

    Alright, Tony! Thanks again. Called Radio Shaq, and the hottie who sold me the AS5, and knew exactly what I meant, etc. I was impressed.

    Got fresh new layer of AS5 applied, and temps are down anywhere between 15 and 25 degrees! Celucius!! That's a LOT! :)
