Normal CPU temperature

[Klaidas]

Hello,
I was wondering, wha'ts the normal CPU temperature?
I have Pentium 4 (1,7GHz), the temperature is almost always 35C (that's 93F)

[heimo]

Seems low, you're perfectly safe. That's about the same as my Athlon 2600+, 1.9GHz runs at.

Yeah, anywhere between 30 - 38 degrees is normal. Over 40 degrees is abnormally hot.

[chimera]

I have a pentium 4 3.2ghz, overclocked to 3.8, and it normally runs at 58 degrees celsium, and it didn't burn yet:D so basically, below 70=good.

[Klaidas]

What about the cooler?
It says 2560 RPM. I guess that's "rounds per minute'?

That is actually slow. It is pretty normal for the fan to run between 2500-4000 RPM's. Your temp is fine and you have nothing to worry about.

[xequence]

My 700mhz celeron is normally 28-35

[Klaidas]

Thank you all for answers ;)

My 1.6 ghz Sempron, when OC'ed to about 1.8 ghz, tends to run at around 25-30 C.

[5-HT]

Am I right in assuming notebooks would run somewhat hotter?

During use, CPU (PIII that has scaling, but it doesn't function in Ubuntu) tends to be at around 55-57 C.
If I leave it for a while, it tends to stay at around 47 C.

Should I be worried, or is this relatively normal for a notebook?

[WildTangent]

My Celeron 2.4 O/Ced to 2.8 ghz hovers around 35-40 degrees C. My Athlon 64 3000 at stock speed is normally around 40-45 C :\ I think I didn't install the heatsink properly or something, because that temp doesn't seem normal to me.

notebooks are going to be hotter because they dont have big *** fans in them. my laptop actually has 2 fans, plus i use a Targus CoolMat or whatver its called (its a little platform with 2 fans blowing on the bottom of my laptop to keep it cool, runs off of USB). i have no idea what the temperature is right now, but its usually a bit hot, but its normal for my machine.

Thanks for the info.
Well the fan does come on quite a bit (better than never), and I've never had a problem with the system shutting down from reaching the default critical temp set for ACPI, so I guess it's all good.

Umm my cpu is frying!!! can anybody help?

Intel Dual Core running at 50-65 Celsius and it runs just fine. I think you're safe.

[FuturePilot]

Pentium 4 HT @ 3.4GHz running 40C or 104F whichever you prefer.

[PurposeOfReason]

Intel Dual Core @ 2.0 running at a cool 31.9C. Hell, my heatsink fan is only going at 900RPM's. You're fine.

Can't make out the information in that pic... too grainy and small.

MSI boards usually have a good passive cooler, so I doubt you will have any problems in that respect. A couple things you can do that will help.

1. Define the processor and slot type. (# of pins as well)
2. Determine the type of cooler you have. (OEM, aftermarket, retail)
3. Upgrade your thermal compound. (Arctic Silver5 is my personal pref)
4. Increase the case airflow. (bundle wires, use round ribbon cables, remove excess wiring)
5. Make sure you have a negative airflow... meaning, more air going into the case than being pulled out. I follow the rule of 3 inbound fans for ever 2 outbound fans.
6. Add a variable control fan

I've got an overclocked AMD FX2 64 3800 running the cores at 2.6GHz (up from 2.2GHz) air cooled and running a stable 35C.

That is actually slow. It is pretty normal for the fan to run between 2500-4000 RPM's. Your temp is fine and you have nothing to worry about.

What kind of jet turbines you usually use as fans? I always make sure that fans on my PC's run at 1000rpm max..

5. Make sure you have a negative airflow... meaning, more air going into the case than being pulled out. I follow the rule of 3 inbound fans for ever 2 outbound fans.

That's just plain impossible.

1. As long as there are any holes in the case you won't be able to get more air in to the case than what comes out. At least not without a powerfull compressor ;)

2. Axial fans used in computer cooling can't create pressure. Only airflow.

It's usually useless to have any fans sucking air into the case, axial fans just simply don't do that well. Instead it's better to put the fans to blow hot air out of the case, more cool air will flow in automatically. And these fans are best placed on the back or top of the case, as high as possible. The only reason to use intake fans is if you have a case with bad airflow and hard disks placed right after the case intake fan, in that case you could use intake fan to make sure there's enough airflow around the disks.

1 intake fan + 1 exhaust fan create together just as much airflow as 1 exhaust fan alone would do.

Normal operation = 43-48
Kernel Compile = Reaches a max of 75-80
:rolleyes:

But i guess this is what is normal.

[ssam]

xeon 5130 (dualcore 2ghz)
idle 32 C
underload 45 C

i dont know if that is good or bad

[Bartender]

P4, ASUS P5GDC-V mobo, home-built wood cabinet..computer is just idling, checking e-mail etc. Funny thing is, running CPUBurn only bumps it up a few degrees

Speedfan sez
CPU 44C
Chipset 32C
Case 25C
HDD 21C

I have a small fan blowing right on the HDD so it always runs pretty cool. Your ambient temps make a big difference. It's only about 18 C inside the house on a fairly cool morning in the Pacific Northwest.

Out of curiosity, how does one find out the temperature of one's CPU?

[jgrabham]

30 but going up since im about to overclock (Athlon X2 3600)

[cawill]

My Pentium 4 3.4 ghz CPU usually runs at < 60 c, but it went up to 73 c for one moment briefly today, what should I do?

[Gremlinzzz]

mines 60 c
better to burn out than fade away

type this in a terminal and it should output your temp:

[-grubby]

mines usually around 110 degrees

[siimo]

My core duo macbook pro runs at 80-95C regularly.

Strangely it didnt go up - but then neither did my performance by that much. Stupid Asrocks BIOS

[RageOfOrder]

My athlon 64 3000+ runs at room temperature. Literally.

20 Degrees Celcius when idling. Never goes above 30 while under load.

I have yet to check my Intel Dual Core 2.0GHz laptop.

[xen]

My Core 2 Duo @ 3.01ghz runs at about 19 deg but that's with a water-cooling setup. I also have an nVidia 8600GTS in the same loop but the temperature reading on this is always inaccurate

[markp1989]

celeron D 352 3.2ghz idles at around 40 C

[ssam]

I found this the other day
http://users.erols.com/chare/elec.htm

i have just replaced the front 92mm fan with a 120mm quiet fan at the back of the case. (I also experimented with having no case fan at all, and the processor did not get much above 45C at full load).

the 120mm fan is a lot quieter.

this is on a dual core xeon 5130 2Ghz.

[iPower]

intel celeron 333Mhz

34 C fan speed 2857 - 3000 RPM

[voided3]

My core duo macbook pro runs at 80-95C regularly.

Yeah, I have a CD MBP too and I use the program SMCfancontrol under OSX and a targus chill mat. With the fans set at 2000rpm instead of the stock 1000 and with the chill mat on, my idle temps usually are around 49-52 C which is pretty good for a laptop. When I play games I crank the fans up to 4000rpm, but even then it still hits about 73 C. WAY better than stock though. If you're crafty, i've heard of people re-doing the thermal paste on these with arctic silver 5 and losing 20 degrees on their temps... might be worth it if you ever have to bring it in to the Apple store for something just ask them to do it (or do it yourself with some help from the iFixit guides).

[hessiess]

core 2 quad 6600, non stock heatsinc(cannot rember the make)

idles around 19 degrees c, around 30 c full load

[iyad202]

I had a couple of laptops and they all ran on a 45-70 degrees depending on how much processing is done. I had on two that were boiling hot reaching 85 and 90 degrees causing the laptop to switch off immediately. The problem was solved by simply cleaning the fans' path and the little aluminum air intakes.
Worked like new after that. And by the way the idiots in the service center of LENOVO (IBM at that time) in Jordan told me it was HOPELESS! So I had to do it myself :)

according to conky it's 10 degrees c but I don't think it can detect my sensors or whatever properly.

And yes I tryed following the steps it showed after putting in sensors into the terminal.

Pentium 4s are know to run hot. Mine likes to hit 60C easily but I don't let it go above 65. I believe the max is like 75C or something like that. Its automatic shutdown is like almost 200F.

[dracule]

idk like 110* F for my laptop

[Lord Xeb]

You really need to get that thing down. It should not even reach 70....

One of my P4's did show me figures like that (I think I saw flames ones ;-), until I bought this little cooler (http://www.scythe-usa.com/product/cpu/030/scktn2000_detail.html).
Mostly temps are around 35, jumps to 45/50 when CPU has to work extremely hard.

By the way.. high temperatures slows CPU speed, I noticed it's performance has increased big time.

[Lord Xeb]

I have known about this for a while. I have an IBM T43 so there is not much I can do there... When I get my machine built, it will be cooled like crazy. I am thinking of putting an Ultra 120 on it with a fan that does like 80-100CFM :D knock temps down like crazy (I am going to have an AMD Athlon X2 2.6GHz, but it is going to be clocked at 3.0 :D). I will eventually get a air conditioner in my room maybe and put a duct going for it to my comp and letting that cool things down more.
