Well i thought i would post this and give you all something to laugh at or think about.

My computer as most of you know will reboot if i try doing a render in bryce. No refrase that, if i try doing anything in bryce or D|S now it will reboot.

Well after a few drinks and long chat with a tech guy i know he put me onto some software that monitors your cpu, psu, hdd and motherboard temp. So when i got home in a slightly drunken state i installed the software and ran it while i used my computer..

After 20 minutes the cpu alert came up informing me that its temp was on a mere 116C/214F....yes i read it correctly, i even had the wife read it to make sure it was correct. At 1am i rang him and gave him the readings on the program, he told me nicely that i was to drunk to use it and to run it in the morning which i did...samething, cpu temp was on 116C/214F after 20 minutes of using the computer..

Guess thats not a good temp for the cpu to be running at :lol:

Anyone want any eggs cooking while i'm typing this...:m_laugh:

Yeah,.........right now my CPU temp is 22.3C and it's been on for14 hours.

Phew! That's hot Dawg! Time for some extra fans I guess. There have been times,(especially rendering animations) when I took the cover off my computer and used a small house fan to help keep things cooler. Good luck with that! Oh, and I like mine "sunnyside-up".

Wow, 116C/214F??

No wonder your pc was shutting down. Time for a big new cpu fan and heat sink.

Going one better guys, going to replace cpu, motherboard, hdd, psu and case fans on Monday (I hope) if not them i'll be without my computer for a few weeks.

I had an old 233 that was doing that  I thought the motherboard  memory and everything else was gonzo - I put it away for a while; later dug it out and replaced the cpu fan, added an auxillary fan that blew across the cpu cooling fins and got it down to close to 100F.replaced the cmos battery  - Bob was my uncle, Fanny was my aunt and there I was.

worked like new  all for a $2.00 battery  $15.00  worth of fans.

another thing might just be dust bunnies..stray carpet fibers, cat hair, dust in general..builds up over the components like a blanket. Sounds like you might have a fan not running..but at least you can boil up some tea with it..;) A good can of compressed air, or your lungs (if you're a blowhard like me..just don't spit..;) might do the trick, or help.

Forget fan,  I think liquid nitrogen is you only hope.

pakled definately not dust or pet hair. I use a modellers(plastic models, cars and planes) hair brush compressor for removing things like that off components, found since i was a radio operator thats the best thing to use. You only need buy one and it pays for itself with in months

Quote - Forget fan,  I think liquid nitrogen is you only hope.

I would love to use LN cooling system on my pc but at the cost of setting it up over here in Australia it would be cheaper to buy a fridge and stick the pc box inside that LOL

If it's clean and the fans work, sure it's set up alright?  All it takes is a few stray BIOs/CMOS settings for overclocking and whatnot...

Anyhow, I've yet to see the CPU on my compy get past 116°F.

Is there any/enough thermal grease between the CPU and the fan heat sink!? If not, it doesn't matter how well the fan is running, you will cook fast!

Another thing as well if my cpu was running that hot my computer would shut down not just reboot 

PS: the temp you  are seeing now on that software is after my computer as been running for 6 hours continuous with me surfing the net, running irc and checking emails. yet when i started this thread my computer had only been running a short time when i first used that software...

Basically, the fan speed sensors will only work if they're plugged in.  On my machine I have a couple of temperature sensors working and only one fan speed measurement.

Speedfan is actually designed to control the speed of fans (hence the name) automatically, but it makes a very good temp checker.

ok

you gotta go in. 

turn off computer

 take off the case cover

make sure you ground yourself on the case a bolt or other unpainted surface on the metal framework to get rid of any static electricity you might be harboring.

turn on computer

see iff the cooling fins for the CPU are cool enough to touch,

see if the fans arre moving at a good speed or at least feel a breeze from them.

if all is ok you can figure the board is shot or you have other problems not easily solved.

if not turn of the computer, replace the fans and solder the connections using a grounded soldering gun cover the connections with electrical tape or shrinkwrap..

I'm not buying that you can't get these fans fairly cheap unless you're living in the outback.any decent wholesale eletronics outlet will have them.  You should also check the power fan, clean the computer  thouroughly, check the fins for grease the way Incarnadine said.(be careful removing and replacing the cpu)

also check to make sore your  wiring is good and that all connections are solid

you can do it!

If you aren't mechanically inclined find someone who is - a friend who lives close by would probably do it for a couple Beers +parts.

good luck,

-TJ(Thanks for the links Mahray).

Looks fine to me.  Most CPUs run between 50 and 70 degrees C (unless they've got serious cooling). Anything over 70 and you should start thinking about fixing it, above 80-90 really needs some work.

I Actually had a Pc die a few years back, fan wasn't turning, and noticed the CPU fan wasn't turning. It was shorted out from the fan. After a few temp alarms going off, my son raised the temp range, and it fried up real nice..;) (shows what happens if you hand off a PC to a youngster..;)

oh yeah!

another place to check is the setup (cmos bios)that you can access only at startup usually by pressing f1 or del;  on some computers there are options for controlling cpu fan speed . mine also gives you cpu temp but the speedfan app doesn't access this data.

Hmmmm, Crazy Dawg, you wouldn't be one of those notorious "Overclockers" would you?

There's something quite fishy in those results. Okay, CPU fan not working... Still, CPU would go to hell in a handbasket if it went up as high as 116 C. And then, the system teperature wouldn't be 0 C. It simply cannot be below the room temperature. When I set up my old comp again, I installed Intel's Active Monitor and I've been getting complaints as soon as the CPU temp rises to 75 C. Yeah, my original CPU cooler is full of dust and what not, so I'm installing a new one, as well as a new PSU. But the highest temp setting the monitor can go to is 100 C. I'd say something went haywire on your motherboard. Sensors broken or something. A new one is probably in order.

a meat thermometer which you can buy in a grocery store for a couple bucks should tell the story.

place it against the cooling fins with the computer running.- your fingers should not touch the sensor(the long nail looking thing that protrudes from the back of the dial). if it's over the max say Mahray's 70C, its a problem.- there are so many cpus out there that you can't depend on a software program to give you reliable results unless the program was designed for that system - even then you should check the results against a physical measurement at least until you're comfortable that the software is giving reliable results.. bear in mind the fins will be cooler than the cpu.

CrazyDawg,

assuming that's accurate, 48C (about 120F) is ok but at the fanspeed youre running to achieve it is more than twice what it should be. I read last night that unless ti goes over 150F it's ok   The same article said that for example an Athlon's sustained max temp can range as high as 180F somewhere around 85-90C and still be ok

What you were experiencing; the rebooting, is part of the throttling process - clock speed is slowed down if that doesn't work it reboots the computer - it indicates that the chip's safegaurds are working and the chip is probably ok because of that.

I would carefully remove the cpu cooling fins(heat sink) from the cpu and check for grease as was previously sugested - only do this yourself if you are mechanically oriented and can take things apart and fit things together without forcing them. It's sort of delicate work.

Also high air temperature, lack of air circulation and high humidity can severely affect cooling.

a meat thermometer? if so, get one that's non-metallic, it's always a bit dicey sticking conductive objects too close to an electrical circuit (don't slip), especially surface-mount stuff. Still, I give it an A for originality..;)

only thing i could get hold of was a plastic aquarium thermometer which i could sit right on the cpu heat sink. The temp reading i got from that was 42C and after two hours of the computer running the temp went up to 43C.

After chatting with a guy on irc tonight about this problem i am having with the computer he advised me to replace the PSU(power supply unit) because to him it sounds like a power drop from that and that is why the computer is rebooting when a load is placed on the cpu. He asked me to run a test which was easy with programs i had and to see what happened. This is the reason he believes it is happening..he also stated that speedfan is the only software he uses to get computer temps because it is the only "Free" software that is true..

I'll replace the PSU and see if that is where the problem lies, if not then i'll replace other things as i get the money  to.

I guess it's possible - I know the transformers I used to buy at radio shack would go out fairly quick in my old electronics projects.I/ve never seen one go out on a computer but if the power supply fan went out ... 

I have seen video cards go out - but just guessed that was what it was and replaced the card with a known good one to test sure enough over 50 percent of the time but if that were the case  the computer would fail to boot up at all..

Good idea - plastic aquarium fan!

for some reason the speedfan software doesn't hook into the temp sensor on my computer HP pavillion(probably not supported) although I do get an accurate reading in the bios setup. 

CD - I think you've corrupted my power supply as well :(

Does anyone know if the voltage readings various programs show from the mobo are accurate?  If they are, then I'm definately in trouble (-0.45V on the -12V rail seconds before a reset).

LOL don't know but I don't think you would  be posting  if it were.

I noticed the Motherboard Monitor wanted cpu information to configure it. Gheck the link below. 

http://www.cpuid.com/cpuz.php

(I always wanted one of these)

Ah, but I'm posting from uni, haven't been able to keep my main box running for more than a few minutes at a time.  That is, of course, assuming it hasn't fixed itself in the meantime...

Don't be misled by the voltage rails dropping - if things are getting hot their resistance may alter or silicon gates change states. IMHO over 50 C is too hot for a cpu and shows that the cooling isn't right -either the thermal layer (paste or pad) is not applied correctly or you have a duff cooler. If you're using a pad rather then paste shame on you or whoever fitted that cooler!.

Of my 2 machines, my 2800 is running at a constant 42 degrees on load, and the 3200+ is running at a constant 19 degrees on load (http://www.aria.co.uk/ProductInfoComm.asp?ID=19756  ,airconned room 'nuf said)

Mahray,

I didn't see any readings which were out of range but then I skipped over a few.

Ok then check

1-the power supply fan

2- cpu cooling fans

3 video card

4)power  connections

1. hard drive and other drives connections to mb

2. dust

3. external connections

4. software - if only one program is causing the fault reinstall it.

try  opening up the case and running a housefan into the machine like AgentSmith suggested last year

if all else fails you know you're gonna have to talk to a guy about a gismo.

best of luck,

-TJ

I've taken it in to the shop, I have four assignments due next week and I need it fixed.  Their considered opinion is that something is overheating (from a cold boot it actually lasts for about 15 minutes), but now it is a process of elimination.

Thanks for everyone's help :)

I think CD must be a jinx or something, no sooner had I read of his problems - but I suddenly had similar ones of my own!

My laptop got so eager to shut down, and did it so often that I'm now using my husband's laptop instead - mine goes in to London for surgery next week.

well..at least I profited from some of this. Opened up my case, pulled out enough dust bunnies to start Playboy Mansion South (ok, I'm dating myself..;). Thing's running a lot better now..;)

Sounds nice and GlacialTech is a good company. But will that cover your CPU? IIRC, you've got a 3200, so I would suggest something that leaves a bit of margin. Might not mean anything, but still...

Erlik i have the AMD Athlon 300+XP cpu and both my tech guy and his wife said that cpu fan will be fine for the cpu i am using. I was going to upgrade the cpu to the 3200 but since replacing the power supply there is no need to just yet

Attached Link: http://www.thermalright.com/product_default.htm

wildman i would consider that one if i had the AMD Athlon 3200 but since i onloy have the AMD Athlon XP 3000 neither of those are suitable as they aren't for my chip so i'll go with what i was put on to by my tech and his wife.

thanks anyway.

SI 97 is socket A along with some others.If you got your mind set no biggie,cause the limba looks like a good one also.
