how hot is to hot for a pc
 

my comp is at 80 normoly is this realy hot for it or not and how much is

80. . .what? celcius or fahrenheit?



FYI if it's 80 kelvin it's way too damn hot ;)

Hah, I wish my computer ran at 80 kelvin - that'd be sweet. Mmm, subzero CPU temperatures.

Sounds like a case temp in fahrenheit, or the monitor you're using isn't looking at the correct address. What's showing the temp?

Too cold for an operating, air-cooled, cpu in fahrenheit.
Too hot for a cpu in celcius. 175f? Come on baby light my fire.

I wish my eyes worked. Totally missed the negative sign when I was converting that ;)

That's around normal - my system tends to run in that range and there's no need to worry.

Downright chilly.

It's unusual to only have a 10*f temp differential between case and CPU unless it's idling after the case warmed up. Try it while crunching something. Prime95, or folding.stanford.edu tasks work well. Idle temps don't tell you about headroom.

Also, to know what's "hot" you have to know which processor down to the core. There are many specs for the various processors.

Still curious what program you're using to monitor temps.

What's the room temp?

My processor generally runs at 328K normally. Under load, it goes to about 338K. I have even reached 343K, after running my Norton anti-virus scan, Ad-aware scan, Spybot scan, RegistryMechanic simultaneaously.

lol...I guess -315.67 Fahrenheit is too hot for you :p

At 353K, you should be VERY worried about the condition of your processor as it might be damaged. Mine reached 353K when I was messing around with switching a different heatsink on and didn't apply enough thermal paste. It got up to 358K before thermal throttling kicked on and shutdown the computer to prevent damage.

P.S. I don't know why I decided to use the Kelvin temperature scale.
For those who do not know: xºC + 273 = x K. There are no degree marks in Kelvin, just the K. 0K is the smallest possible temperature value, nothing can get colder than that, at zero kelvin, all molecular motion stops. Quick physics/chemistry fun fact there.

Yeah, all procs are different. If you have an Intel proc, head out to...yes, Intel and look it up. You will find max temps posted there.

For my machine, I use the Asus Probe (not Anal Probe) to check the temperatures. I am idling now at 84F for the proc, and 87F for the MB. If I am gaming, the temps get up to around 105 or so, but that is well within range.

Intel P4 has a max temp of 70C.

I had overheating probs a week or so ago, and cleaned the dust from the fan and heatsink and dropped the temp 10-15C. I run around 45-50 after extending playing...

All,

I'm having a similar problem. I recently upgraded my PC from a P4 1.9ghz to a P4 3.0ghz, replacing the motherboard, cpu, a new power supply (Antec TruPower 2.0) and an additional hard drive.

I also have exhaust fans in the case. One is in the front and draws cool air in, while two are in the back and are blowing hot air out. However, I installed the desktop utilities application today and I'm startled.

Processor Zone Temperature: 144F
System Zone 1 Temperature: 111F
System Zone 2 Temperature: 99F

Can anyone provide any remedies to this situation. I know these temperatures are not dangerous, but they are on the high side of normal.

Thanks!

Tornadored,

P4's are hot but you're right, that is a little high. Is that idle or working temp?

Case open or closed? Any cables in the way of cpu airflow?

New heatsink/fan? Clean? Intel or aftermarket? Designed for recent P4's?

Is the fan running at full speed? If it's connected to a temp-controlled power connector on the MB, can you change the trigger temps in the BIOS?

If you installed it yourself, how much thermal compound did you use? Less is better.

Tornadored,

Idle and working, it does not vary much.

Case closed, I worked today on organizing the cables to keep them away from the cpu.

New heatsink/fan? Clean? Intel or aftermarket? Designed for recent P4's?

All new, Intel heatsink and fan.

Is the fan running at full speed? If it's connected to a temp-controlled power connector on the MB, can you change the trigger temps in the BIOS?

I'll check it out.

None, the chip did not come with any.

Thermal pad 775? Which? Max temps 155.8 to 156.4, depending on model.
What's creating the load for working temp?
Nothing under the HSF that might interfere? Wires can get caught and separate the surfaces.
Plugging the cpu fan into a case fan socket that's temp controlled can be bad. Just in case.

775....

The load is not much, I had the software setup as default earlier, and I would just open up IE and get a warning about overheating. Since then I have increased the threshold a few degrees.

Nothing under the HSF, just checked it out.

However I did unplug the fans from the PS controlled plugs and put them on the standard connections. The fans are running faster now. Here is what I have:

Processor Zone: 140F
Sys Zone 1: 108F
Sys Zone 2: 90F

A bit better...

775...? The temp limits vary by a few degrees depending on specific model.

Here's a good specification summary with max temps:

Search for "P4-xxx" where xxx is 571, 670, etc.

I'd want to know working temps. Fire up the http://folding.stanford.edu/download.html client for a couple minutes.

You mentioned there wasn't anything under the HSF. There should have been a small square pad of conductive material. It's protected until you remove the heatsink from the packaging. If you don't have either a pad or grease, or if something got stuck to the pad, then that would cause high temps.

Intel Pentium 4 531 800MHz FSB LGA 775 EM64T

Looks like my max temp is 67.7° C (153.86° F)

As I type this I am running at 140°F.

Under the HSF, I remember installing the processor, and then setting the HSF over top of it. Do not recall messing with anything. Then again, it was last week, and lately I haven't remember what I've done yesterday.

I'll do some folding and post some numbers.

Thanks!

Crunching at 169° F.

I'd hold off on any heavy work for now. There's always some error but 169 is beyond a comfortable fudge factor, assuming you're on the good side. Consider room temperature and what'll happen in the Spring/Summer as case temps rise.

Join the club. :)

I'd check the processor area for airflow. Is there a good exhaust path or is the air recycling? Does the power supply have an inlet just above? Is there a case outlet fan nearby?

If case airflow isn't helping I'd check the processor/HS junction. The stock pad is easily damaged so be prepared with thermal compound. Clean both sides with alcohol and apply a grain of rice sized blob (large rice but small blob) in the center. If this was a problem you'll see some change immediately, though the interface will improve over the following days as the compound settles in.
