My P3-933 keeps overheating! Help!

[Medster]

Hello, I just put together a new system. It's a p3-933 running on a CUSL2. The CPU keeps overheating and I'm not overclocking anything! When I boot up, PC Probe will say my CPU is running at 200F. About 10 seconds later it'll cool down to 73F when it's idle. Even when I go into my BIOS at start-up it'll say the CPU is running really hot. Sometimes the system speaker will beep extremely loud to let me know it's overheating. Counter-Strike starts to get choppy (I have a Voodoo5 AGP) whenever sounds play, and sometimes it'll boot out cause it gets too hot. I'm using a Golden Orb heatsink/fan, and I also have a chasis fan. Can anyone help me out here? I don't know why it's running so hot or what to do! Please help. Thanks.

That's probably just a bug in PC Probe! Did that on my P3v4x motherboard to but it was never overheating!

A couple of questions first of all, is your cpu shutting down completely to where it won't operate? Second, are you sure you applied the heatsink correctly and got enough thermal grease on your cpu? third, the heatsink/fan combo that came with your cpu should be sufficient, and this really shouldn't be a problem, however, on the offchance you got a hot running cpu, try to get an upgraded hsf such as an alpha pal6035, or even a globalwin golden orb. Both of these will cost you between $20-30.

I suppose if none of this works, there are a few more things you need to consider. Do you have front and rear exhaust fans on your case? If you do, go to www.amd.com and go to the support section of the site, there is a nice diagram there of how the fans should be blowing in order to create the best airflow through the case to keep it cool. Yes I realize you have an intel cpu but this is a nice diagram. Air should be sucked IN through the front of the case and sucked OUT the back of the case.

Lastly, how spacious is your case? Do you have a desktop case, mid tower or full tower? Consider looking inside and seeing if the ribbon cables are blocking your airflow. You might need to invest in some rounded ide cables here if this is the case, in order to create some more room. That's about all I can think about as far as cooling issues are concerned. Hope this helps.

Well first of all, it's not a bug in Pc Probe. I just downloaded the newer one, and it's giving the same results as the BIOS also do. The speaker also beeps extremely loud sometimes until I shut it down and let it cool off.

Yes, sometimes the CPU will actually shot down by itself because it gets so hot. I'm sure I applied the heatsink correctly and plugged it in. About the thermal grease, was that the little white block on the bottom of the heat sink? That did get rubbed a little when putting it on. It's still there, just a tad spread out tho. As for exhaust, all I have is the chasis fan in the front blowing into the case. I'm using a mid tower case, and the ribbons are quite messy. I just don't think that it would cause the CPU to be running over 200F sometimes. Thanks for your reply.

What mobo? Might be bios error, or thermal probe broken.
Not possible it's working @ 200F

 

[Medster]

It's a CUSL2 board. I doubt it's a bios error, I've tried 1002 and 1003. It's not a misreading either because all of my games get choppy and are unstable.

Make absolutely positively dead on balls sure that that heatsink is sitting flat on the chip. If there are any gaps between the sink plate and the chip, it does not take much for heat to not transfer properly to the sink. You also want a nice THIN EVEN layer of heatsink compound/grease. Applying 2 much will insulate and screw up up.

What a coincidence, I just stopped by to ask the same question!!!
My PIII 933 on my ASUS CUSL2-C is running @ 50C/120F, straight up no overclocking. Is this the normal operating temp?

 

[Medster]

I'm sure that theres no gap between the heat sink and P3-933. I even ran the BIOS temp test while I pushed down on the heat sink as hard as I could and the temp didn't change at all. The golden orb came with the thermal goop already applied on it, but it got a little smudged while putting it on. I dont know if it that matters. Running idle in Windows it's at about 108F, but as soon as I run anything cpu extensive, like Counter-Strike, Worms, or even copying huge files over the network, the temp skyrockets to 200F! Everything gets real choppy and the system speaker will even beep a couple of times.

Those figures are from the bios, with the system idle.

Alright, I just got off the phone with Intel, and here's what they gave me:

-The idle temp should be at 45-55 degrees Celsius(113-131F)
-The max temp is 75 degrees Celsius(167F)
