How hot does your computer run?
 

ms. birdstrike's Sony VAIO fan was howling, so I cleaned the dust from the vents and it calmed right down. I then installed SpeedFan and checked the temp on the CPU. 73C.

I then installed SpeedFan on my 3GHz P4 and found it to be running at 127C (no dust inside this one!).

SpeedFan is a cool little utility that displays the output of many internal sensors I only generally knew existed.

How hot does your machine run?

41-43 F normal running.

Consider using a dynamic-switching program. It changes your CPU's clock speed depending on the amount of work it needs to do. (As in, the software tells the computer to supply more voltage to the CPU when it needs to work harder, but tells it to cool off when it doesnt have much work.)

Try googling "Notebook Hardware Control" and it'll take you there. It's free and there is a good amount of guidance regarding how to install it. :)

Are you sure that 100+ one wasn't in degrees F instead of C? If not, that is WAYYYYYY to hot. My laptop runs around 45 or so normally. Fans turn on low at 60 and high at 70. It automatically shuts the computer off around 85 or so.

I use 18kfangui and Notebook Hardware Control (I have a dell inspiron 8600)

Pretty hot. I have a CD MBP.

The numbers posted do not make sense.

41-43F is refergerator temps. probably 41-43C

127C should shut down the system(an hour before). most have an automatic switch that sut them down well before that, and if not, the processor probably will not work at 127C. 127F is about 50C, which is plenty warm.

a few mega-buck mil spec semiconductors will run at 125 C.

My new desktop econo-computors run new AMD processors. I notice the fans are miniscule compared to the old fans on pentiums. I like that. they are very quiet. I presume they use less power, and make less heat.

Now that I'm looking at in the morning, nothing seems to make sense. The laptop was turned on this morning after being off all night and is still claimed to be 73C. My tower is still 127C which I agree is way to hot. I don't think this program is reporting what it claims to be reporting on my systems.

I'll have to poke into this a little later. . .

AHAHA, yeah it was 41-43 C. My bad!

I know you're dealing w/ PC's, but on my PowerBook G4 version, the temp is only calculated upon boot up, so the temp. display widgets don't change unless I reboot. Perhaps your tower is doing the same thing. (sure hope it's not 127C though!!)

do the people giving speedfan as a freeware program sell cooling fans?

I have an Intel Core Duo 2 Macbook Pro and I must say it is not nearly as hot as my brother's late model Powerbook G4.

My MBP is actually not so bad, it keeps my legs warm. I have not yet felt like it is going to burn me, whereas the PB felt like it would burn you.

That's why Apple turned to Intel, Motorola (or whoever was making the PowerPC's) could not deliver a G5 chip for a laptop that would not run unsafely hot.

I have a Gen 1, Macbook Pro and it sometimes gets as hot as 85C, which is 185F.

It typically runs around 60C / 140F.

Wow, I think my laptop is the coolest running among those posted.

I need to clean my vents however, as my fan is NOT happy. But with my Sony VAIO S360-P it runs around 35-40°C which is pretty cool. I think the hottest I've ever seen it run was at 41°C. No burning lap for me! ^

Just got a MacBook Pro Core 2 Duo.

It's quite cool.
The fan is also quite loud. ;)

My previous model Powerbooks were significantly hotter.

Have never used a widget to track the temp of any of the machines I've used, so I'm no help for real numbers.

Yea, mine hovers around 35-38C, and I still think thats too warm for a AMD. Anything over 70C would be damaging to your CPU.

There is some risk running Speedfan. On my Dell Dimension P4D it crashed windows XP (simulated hardware fault and hard stop - something that doesn't happen too often except with bad drivers). Uninstalling Speedfan fixed things. Looks like Speedfan only works with the planars listed, and can do some harm on other systems.
