Hi All, Does anybody know what is the normal running temp for a 1.8 Ghz cpu ? cause mine is running at 71 degrees,Idon`t think that right !

Definetely not 71c that's high as sh*t, i wouldn't be turning it on or you could fry your cpu.First of all where are you getting those temp readings from..the bios? or some program? if it is the bios it's probably right, then your going to have to make sure you have thermal paste on there and that the hsf is installed flush to the cpu.the normal temps for that cpu or any cpu amd or intel is between 30c and 40c max(normal) but it can go up to 55c with no problems but it could cause damage.60c and your getting real close to fried popcorn lol. if it's not the hsf or the paste it's either case ventilation or bad cpu.if it's the cpu, just buy a new cpu 1.8ghz are cheap these days.

You temperature sensors could be off. Did you install the CPU yourself? Touch the heatsink while in operation - if it's too hot to touch with your finger, something is terribly wrong.

Your P4 would not be fried even without heatsink and fan. It will stop running, but will not be fried as tested by Tom's hardware. AMD will be fried within seconds without heatsink and fan. Yes, your CPU temp is on the high side even with Willamette which has a max Tcase temp of 75C. But, the Northwood 1.8 is 68C. Then, it depends on your room temperature. This time of the year in Texas without air conditioning it could be 32 to 34 C, which makes the 71 C not as bad as it sounds for a Willamette. If your system does not crash you should be fine. Try some case fans if you don't already have.

It still can cause damage(fry)whatever you want to call it..and shorten the life of the cpu.

Nobody keeps the same comp for more than 3 years these days, unlike the 70's, 80's and 90's. A laptop runs close to 100C. I have been using laptops since 1992, never did the processor (fried) damaged from heat. The most often damage or fry comes from spilling coffee while working in the bed. Again, enjoy overclocking, your OS will give you hell a lot of problem before your CPU is fried. Like a human body which gives you hell a lot of pain (warnings) before you "die".

Thanks guys for yr messages, I think i found the problem .....there is no thermal paste between the heatsink and cpu + the cpu fan is running at 4000 rpm i think it should be more ey ?
