Whats a good temp for a PC to be running at, mine is currently at 84F.

Computer temperatures are usually talked about in Celcius. This helps keep things simpler. 84F is approximately 28C. This is a very cool temperature, so I imagine that this temperature refers to your system temperature (the temperature of the air that is in the case) and not the temperature of the CPU. I noticed in the pic that you had in the other thread that it did say CPU 84F, but just because it says, doesn't mean that it is accurate. How was the thermal probe (the temperature sensor) installed? If it wasn't installed properly or wasn't installed on the chip at all, it isn't measuring the CPU temperature. If you want to confirm the CPU temp, get Speedfan. This program will access the temperature monitoring chips inside your CPU and motherboard and give temp readouts.

Hardly anyone agrees what temperature a CPU should run at (other than cooler is better that is). I find a range of 40-50C to be acceptable for my system. The important thing is to not allow your chip to get too hot. Different chips have different thermal tolerances. I believe that your chip (AMD Athlon 64 4000+ San Diego) has a maximum thermal tolerance of 80C. This means that damage can occur to your chip if you run over that rated tolerance. In that case, I would recommend never letting your chip exceed 60-65C.

Its at 26 Celcius - I changed the temp from celcius, but changed it back. And yea thats part of the Cool'N'Quit Technology, its connected directly to the CPU ...

You're not reading what I post. AMD's Cool'n'Quiet tech has nothing to do with what you are talking about.

Just because the readout says 26C or 84F or whatever other number next to text that says CPU doesn't mean that it is accurate. If you want to know what your temps truely are (AMD chips have thermal sensors built into the chip itself), download and run Speedfan. If the thermal probe was improperly installed or the readout is defective, the temperature that the display is showing will not be accurate. I know about this since I have built machines that have those readouts, so please trust my experience.

FYI: The reason I believe that the readout isn't accurate is that 26C is way too cool to be reporting your CPU temperature unless your system is watercooled or your room is a freezer.

Just ran Speedfan. And this is what it says.

Temp 1 - 30C
Temp 2 - 26 C
Temp 3 - 27 C
Local - 33 C
Remote - 37 C
Local - 33 C
Remote - 45C

Temp says 117 C. Is that temp of the whole PC? Thats over boilings O_O.

What's a good upper limit for a Pentium IV laptop CPU chip (you said 60-65C for Athlon). Both my fans have quit, and I'm trying to get away with an external fan platform). I have an old Presario 2500.

many different p4 chips ,scroll down to see intel chips see if you find yours .

nice programme that speedfan... but geez internal heat is at 99c.... while others alr between 30-35

hmmmm my CPU it won't show and I deff have an AMD CPU

Im not really satisfied with this programme to be honest... and well it has overclocking mode in it... so I recommend only experienced users to use it!

Thanks, Odie. I'm aware of the limitations and I've stayed far away from overclocking.

Just for reference (using asusprobe), my temps are:

cpu - 35
mb - 19

Using speedfan:

temp1 - 20
temp2 - 36
temp3 - 26
temp - 126
temp - 126
hd0 - 27
hd1 - 28
core - 39
core - 43

I find the 126C temps interesting. I will have to dig around to see what that is trying to read. - Oh - just a couple of unknowns. The second core is my graphics card, the first is cpu - kool program, thanks for pointing it out
