*URGENT CPU overheating*

[nehalmistry]

help me, i changed multiplier and frequency and overclocked my cpu from
66 x4.5 to
100 x3

both 300 mhz... but my CPU started to overheat.... then i changed it back and its still happening.... the fan seems to be working fine, and nothing is blocking it.... i dont understand....

help me.... i need to fix it asap...

thx, nehal

I thought there was a time when 2 sorts of K6-2 CPU's were produced, one was meant for 66MHz FSB, the other for 100MHz. Appearantly there was a fysical difference between the two types. Probably the K6-original only was produced like the 66Mhz version of the K6-2, and therefor can not reliably run at 100MHz FSB?

just my guess...

[nehalmistry]

yes, dzeus, you are correct, that was the whole point of me doing that.... but now that i changed it back its still overheating.

What should the temperature of my CPU be

my K6-2 350 never went (sold it a year ago) over 35 degrees celcius.... even with a 100% load.

Is there thermal paste between your CPU and your heatsink? and is the fan functioning properly?

[nehalmistry]

yes, the fan is functioning properly... everything was working fine before.... but now its going crazy.... even when i put it to 133 it goes up a degree every minute....

i dont know about any paste... and i never had any paste on....

I had a similar problem a few days ago. I was switching cases, and after the temp on my CPU was rising by a degree every minute. What happened was that I had knocked the Heatsink lose a little. This wasn't evident by looking at it from the top ( it looked connected fine) finally, I removed the processor, and was able to see the heat sink was not connected properly.

Its commendable that you are trying to make
silk purse out of a sows ear but I think its
time to move on and upgrade...I dont know why
nobody has said this yet unless they dont want to hurt your feelings but these forums
are for giving advice and I can say that this
is probably the best move you can make....

yosh12: uh, im not trying to make a 'silk purse out of a sows ear', like i said i already did overclocked it, then i put it back to normal, im trying fix my fan now, i dont know what planet ur on...

KIL: WHAT IS THE HEATSINK. IS THAT THE BIG THING BETWEEN THE FAN AND CPU. AND HOW DO I FIX IT. I THINK THAT MIGHT BE THE PROBLEM BECOS I TRIED EVERYTHING.

Take a look at the heatsink and fan (yes the heatsink is the metal object the fan is fixed to). Is it perfectly flat against the processor?

Between the heatsink and the processor, is there any heat transfer compound (usually a white gooey liquid)?

It's possible that the fan seems to be working but not spinning fast enough...

And by 'increasing at a degree every minute' at what temperature have you seen it go up to?

i took out the CPU and took of the fan, the heatsink looked perfectly flat against the CPU and i DID see some white gooey stuff. no problems there.

its not possible that the fan is not spinning fast enough. it has been this speed and everything was fine..

maybe this is helpful, yesterday i was playing HL AFTER changing settings to 100 x3 and the fan wires came loose, i didnt know this until the power light on my case starting flashing, i immediately shutdown my computer, went into bios checked the cpu temp, it was bout 75 degrees CELSIUS... after i attached the fan, things obviously got better, but still the temp is still rising, for eg, the temp right now is about 40 degrees, when i starting typing this it was about 37 degrees.

i dont know what's wrong, otherwise i will hafta put in my old pentium-I chip and i don't even know what speed it is, and i will probably run into more problems.

75 degrees celsius for that little cpu?! Think you may have fried it? If not from the heat, then from the 40% bus increase on the cpu....

[dZeus]

If I were you I would get a new heatsink.. they sell them for under $10,00 and those will probably do the job (however, I think the K6-300 was notorious for it's power consumption (=big heat production)

And yosh12, you're not being very nice... Not evryone has the money to buy fast things all the time... for example I have a Celeron 366 right now.... Am I happy when UT performance suck in Win2k? Hell No! but that just is reality, and I will upgrade my memory first (add another 128MB ram.... I have to buy 64MB to get another 128 in my workstation.... why? that's another story)

[nehalmistry]

thats right, im 'not' a rich SOB, and my parents are unwilling to buy me any new sh*t for my computer.

if it was fried, wouldnt that mean it would not even work anymore???????, i mean its running fine, except for heat problem.

i am doing ok right now, i have a cpu cooling program that keeps it to 34 degrees which is ok. but obviously i cant play games.
as soon as i disable the cooling the temperature goes back up a degree every 30 seconds.

dzeus, i dont think its the heatsink that's causing it.

maybe the clips that attach the heatsink to MB are causing a problem, should i try taking those off?

uh Im on the planet earth and you are from??
I wasnt trying to piss anyone off but I see
a few saw it that way...and you dont have to
be rich to plug in a Celery or Athlon....
maybe you should get a job and then you
wouldnt hafta ASK your parents to buy new
comp.stuff...

I was speculating when I said "fried". You pretty much said that you didn't do anything to the hardware, so I assume that is not the problem. The change that caused this to happen was the overclocking. (I'm talking about nehalmistry's computer, not Kii's computer)

So based on that, I am speculating that the overclocking somehow fried/overheated/changed something on the chip that is causing this problem. I'm not an expert, but it is the "logical conclusion"

Even if you aren't a rich SOB, you can replace that k6-300 with a k6-2 500 for $50. (Assuming your motherboard supports it) It is something I would consider because I wouldn't take the chance of that chip corrupting any data.
