Swahili Babel	Posted - 2008.01.08 21:02:00 - [1] Ive been having a problem with my computer. I t has started to freeze completely from time to time (including mouse pointer etc). I thought it was due to dirt and lint covering the openings in the case so I cleaned it all, with no luck. So I dl a little tool that monitors the cpu temp and more, but turns out I have no idea if the temps are high or not. Here is a screenshot from the application. Would appreciate some help with it.

Swahili Babel	Posted - 2008.01.08 21:10:00 - [3] Well, I might have misnamed the thread, my biggest concern is the "Core: 81C". You know what that is about?
ReaperOfSly Gallente Lyrus Associates Enuma Elish.	Posted - 2008.01.08 21:12:00 - [4] "Core: 81C" is worrying. As is the fact that all your fans seem to be moving at 0 RPM (which would indicate a fault with the program if your fans are indeed moving). My CPU runs at ~ 70C under full load and even that has me worried enough to order a new heatsink and more case fans. I haven't used SpeedFan myself, I use Core Temp which seems to be simpler. Can I suggest you d/load that and compare results? By all accounts, Core Temp is more reliable. --------------------------------------------------------------------
Fink Angel Caldari The Merry Men	Posted - 2008.01.08 21:17:00 - [5] What he says ^ Core Temp is the only program that gives me acurate results on my Mobo. Speed fan is showing all my fans at 0 RPM (Hint, I can see them spinning!), and: CPU = 34 Core 0 = 42 Core 1 = 40 Core = 67 Core Temp is showing 58/57 which I believe to be accurate and is in the hot range of normal as I'm overclocked from 3Ghz to 3.6Ghz

Can I suggest you d/load that and compare results? By all accounts, Core Temp is more reliable. The 0 rpm reading is simply cus the fans either probably don't have speed control, or aren't connected to the motherboard its not uncommon to see fan speeds registered at 0rpm but its pritty much a garuntee that theres some fan movement as the cpu wouldn't be at around 43 degree's I'd also debate core temp as been the better tool, core temp seems to have lack of support for a variety of chips out there. Also simply ordering more fans and a new heat sink isn't a guarantee that it will improve your running temperature if the airflow in the system isn't moving the heat away from the heat sink rather than just stirring up the air. Lot of people forget that these days when building their own systems about planning airflow. Sig removed as it lacks EVE-related content. Mail [email protected] if you have questions. -Hango

My case is not what you'd call overcrowded - I built the thing on a shoe-string budget so it doesn't have alot of components to get in the way of airflow --------------------------------------------------------------------
Maltitol Gallente Tides of Silence Hydra Alliance	Posted - 2008.01.08 21:35:00 - [8] Originally by: Swahili Babel Well, I might have misnamed the thread, my biggest concern is the "Core: 81C". You know what that is about? sorry about that m8, i didnt even see that line.. what does your bios say for temps? i say run a really heavy game/prog, immediately quit and reboot, read the cpu temp, take off 5 degrees & that's as accurate as it gets... core and cpu... i dont know why they are seperate. open your case, and run the machine open, see if you get a different reading (as in if it gets cooler) put a huge fan on it see if it gets cooler, if it does, might want to think about a fan for your case... 81 is about the temp when it starts to cook your board. you aren't overclocking are you? have you re-seated your fan on the chip at all? if you have, you may need to re-apply the paste on the fan itself, i ran into that once....

ToxicFire Phoenix Knights Dark Nebula Galactic Empire	Posted - 2008.01.08 21:43:00 - [9] Im pritty sure 81 is also outside the operating range of a intel core 2 duo which im guessing it is. But i can't seem to find the spec right at the moment Sig removed as it lacks EVE-related content. Mail [email protected] if you have questions. -Hango
TheWench	Posted - 2008.01.08 23:13:00 - [10] SpeedFan is funny, on my machine it reports a random AUX temp of 119C as well as Temp1 and Temp2 both at -48C. Whatever they hell they are supposed to be

Whang'Lo	Posted - 2008.01.09 03:05:00 - [12] Well your question is a little vague, need more info. What kind of processor? How long has it been running with no changes made whatsoever? How long does it run before it locks up or is it total random? Kind of shooting in the dark here. Alot of people have had problems with the stock coolers on the intel processors though. I know I got rid of mine. But yeah it has 4 connectors that hold it on the mainboard and if one of them is just a little loose it will cause overheating even though it looks like its connected just fine. But a problem like that would show up not too long after initial build I think. I would say the main reasons for random lockups would be in this order: Overclocking (bad config,overheating etc etc.) Overheating (not always processor could be something else with a heat issue) Old Power Supply not enough juice Bios settings (strange timings) Memory (trying to get too much out of old ram, or junky ram) Ghetto Mainboard Don't taze me bro!
defiler Mad Hermit	Posted - 2008.01.09 05:50:00 - [13] Edited by: defiler on 09/01/2008 05:52:44 Hmm, 81¦ seems a wee bit high. Still, might be perfectly acceptable even in the long run. My suggestion to you is that you run some hungry app(s) in the background to keep the CPU usage at 100% and then slooowly throttle down the fan (just a few percent per minute) until the CPU reaches 85-90¦C or something. If it works, great. Now leave it running like that for at least an hour. If it works then you know your problem is caused by something else. In case you're wondering, doing this will not fry your CPU, or anything else for that matter. If you gently overheat a component like this it will simply fail (or trip some protection circuit) and shut itself down/lock up long before it would suffer any damage. (However, I take no responsibility if it blows up, savvy?) Hmm, maybe it's time to raise the heat a bit. I've used SpeedFan for well over a year to keep the CPU (AMD X2) running hotter than it wants to. If I disable SF it seems that my comp tries to keep the temp below 40¦ which honestly seems a bit excessive - I can maintain 70¦ with a fan speed of 80% which makes it almost inaudible (idle at 50-60¦ with 20%), but maybe I can scratch that "almost" if I let it go to 80¦... What could possibly go wrong? Well, if I leave you in peace on the forums for a while you'll know why. Mad Hermit corporation Minding our own business since 2004

So this may not be a good idea unless you replace your computer once a year or so.
Lilan Kahn Amarr The Littlest Hobos Insurgency	Posted - 2008.01.10 22:58:00 - [15] just make a big ******* hole in your case and install one of those hugh case fans or play with the side open for extra air flow. sitting at a nice 21c full load "Bringing Content to you 1 round of ammo at a time"
Audri Fisher Caldari VentureCorp Imperial Republic Of the North	Posted - 2008.01.11 02:40:00 - [16] make sure you have intake, and exhaust fans... as in pull air in from the top( avoiding dust that settles on the floor) then push it out the bottom. If that doesn't help, reverse the airflow,, but clean the dust out every week or so.

If that doesn't help, reverse the airflow,, but clean the dust out every week or so. i put bounce (laundry) sheets on my intake fans & holes with no fans, never on the power supply, and never on the outgoing fans. makes a nice fresh scent, AND stops dust!

So this may not be a good idea unless you replace your computer once a year or so. Just a quick CMA here... While it is true that high temperatures increases the risk of permanent damage it is unlikely to by itself shorten the MTBF by more than a year over a ten year period. What really damages your CPU is temperature changes. Keeping ones CPU at a toasty 75-80¦ is far better than letting it swing rapidly between 20 and 60. You do have to keep your cooling in check to keep the temperature stable of course, and you have to accept the (arguably rather low) risks before doing anything. I'm not saying that everyone should run their CPUs above recommended temperatures (I pity the fool who does anything just because "some guy on the forum said it was ok"), I'm simply saying that it is an option.
