i found a program in another post called speedfan so i could see my computers temp. It says HD0 temp is 62C and temp1 is 53C. is that hot for a p4m 1.8ghz? it feels hot.

If Temp1 is CPU temperature, it seems OK. If it is motherboard (chipset) sensor, it looks too high. You can easy determine which one it is. Just suspend/resume BOINC and watch for graph. CPU temp with/without load will raise/drop faster.

HDD temp looks too high, but sometimes it can be explained by inaccurate sensor. Maybe it isn't connected at all (it happens) and gives some random value, so similarily you can monitor it running some disk-intensive operations, e.g. copying big files.
You can compare SpeedFan data with BIOS readings. Also you can watch for the HDD temp on the cold machine. Turn it off, let it cool down for 20-30 minutes, then turn it on and check BIOS values immediately. Then boot your OS and check SpeedFan values as soon as it loads. All temps should not be much higher than your room temperature. If you see big differences, you may enter non-zero biases in SF settings.

I would be more worried about your HardDisk then your CPU. Operating temps for HDD is 5-55c. But I wouldn't recommend going over 45c. Remember, the HDD is mechanical, has moving parts. The cooler you keep it, the less chance you have of a HDD failure.

I seem to recall being told that 50 is about the max you'd want to have for your CPU.
Hullo there.

I had a system running for several years & the CPU didn't get below 65°c very often at all. 70 is about the limit.

The exact limit depends on a CPU technology, some can work even at 90C. But 50C can't be the limit anyway, it's too low for any modern CPU (well, I'm not sure about ancient 80x86 LOL)

I installed speedfan and it reports my HHD as 33C and my CPU as 86C for my Dell Laptop.

86C for the cpu is very high, i would try to keep cpu's below 70 (no matter what at what they might still work, they suffer from temperature), ideal id say is around 55C or lower. hdd i would keep below 40C, if higher it would have to be spikes during copy/defrag or other disk intensive tasks.

You need to look up the max die temps for the CPU in question and then leave a 20~25% margin. Each CPU model group will have different specs. Here's a chart of the AMD CPUs from about a year ago and back. AMD

On my IBM T41(1.6G P-M laptop) MobileMeter reports CPU@67c and HDD@32c after running 24/7 for the last 5 days with CPU pegged @ 100%. The laptop is sitting on one of these...

Cooler

The cooler seems to take the CPU temp down 3 to 6 degrees c and the HDD temp down about 1c. But this just brought it down to a tie with my next hottest CPU, an old Barton XP2500+ clocked as 3200. Everything else is is down around 50c (122 F) or lower.

I checked and found my P4 1.8 (same as original poster) was on an Asus P4B266-L board and I loaded speed fan. It states:

temp 1 -128C
temp 2 -128C
temp 3 59C

I don't know what they correspond to and am looking into it.

[edit] I've recently (within last week) took it apart, replace thermal compound, and removed ALL dust bunnies. I'm thinking temp 3 is my western digital WD1200BB hard drive.

I'm not sure cause I have not seen anything to tell me but i'm guessing the red up arrow and the red flame thingy in Speedfan is bad and the blue down arrow and the green check mark is good. Right?
I have one of those "Chill" pads but it works agaist the fan in my laptop because it tries to pull the air down from the bottom of the laptop and push it out the back. Meanwhile, the poor little fan is trying to pull air from the bottom of the laptop and feed it out the back of the laptop!

Well it would seem that those are the real temperatures. when i first turn it on the temps are lower but go up gradually to that point. the hd gets that hot even if im barely doing anything.

Is it possible to overclock a dell? what kind of motherboard does a latitude c840 have?

Temp1 & 2 are meaningless, it's just disconnected sensors, which give 1000000 binary at open input pins. 59C is too high for HDD, it's more appropriate for CPU. Check how it changes with CPU load and heavy disk operations.

Update: After coming home and setting my Dell laptop up it runs without the fan going most of the time. I'm thinking my office may be too warm for it.

From what I know you should really keep your harddisk temp (HD0, HDD, HD*) below 50C... don't know if your readings are correct though. Never seen a harddisk at a higher temp than the CPU...

Basic answer- if the system is retunring valid results & it's not locking up, falling over or spontaneously rebooting then it's not too hot.

You can get a HD cooler for only about $6.95 at Tigerdirect and other places, installed one and the HD temp dropped by close to 10 degrees C, well worth the money, have them all both systems now.

Extra fans to get air into and out of the case are cheap and do a good job also. By keeping tha air moveing and getting fresh air into the case will keep everything cooler. My newest system has a 120 mm fan in the frunt and 80 mm on the side blowing air in, and an 80 on the back blowing air out as will as other vents on the back to get it out. Sometime I will have to check the temp in there with them off, than with them on and report the diferance. With the 2 40 mm fans on the HD cooler it makes an extra 5 that I added.
