What Temp should my P4 3 ghz be running at?

[gaz_0001]

Hi,

my Dad has a P4 3.0 Ghz processor. I recently installed everest onto his pc and it is showing the temps at 56c idle and then at 71c when the computer is run at 50% CPU utilization for about 20 mins.

There is some video camera DVR surveillance software on the pc, and when thats on its constantly at 50% cpu utilization. Thats how i have got the figures.

I checked on the intel website and from what i can see 70c is the max temp rated for this processor. Is that correct?? Because i just dont think it should be running at over max rated temps given that its onyl at 50% cpu and not overclocked or anything!

Thanks

Gaz

Might want to clean the sink of any dust or add better case cooling, is this a Prescott cpu? If so then your temps are within reason as some of those were hotter than supernovas, an aftermarket sink from Thermalright or a Big Typhoon would likely bring temps down though. Those temps you're getting are not abnormal with prescott cpus and stock sinks.

My 3gig northy idles at 40c loads at 63c , thats running cpu fan at 5vts

With the intel stock cooler, I've seen 3.0Ghz Prescott's hitting 85 degrees while under 60-80% load. The earlier prescotts did have some heat issues, and a stock cooler combined with a low quality 'case airflow' can easily cause them to get very hot.

71 degrees is quite acceptable for a full load temperature on a Prescott, but if thats only at 50% load, I would look into improving both the case airflow, and the cpu cooler.

Could I ask what thermal interface material you are using? The only reason being stuff like Artic silver needs replacing every couple of years as it dry's out.

I had an issue with my 6800gt when this happened it was running 120c I just replaced the AS5 and temps came back into line.

Many Thanks for the replys.

I am using some software called everest ultimate 2006 to get my information.

The processor is a Intel Pentium 4 3000 Mhz Prescott.

On idle with stock cooler and 2 x 8cm case fans rated at 27 cfm one intake one exhaust.

temps were 57c on idle, 71c on 50% load constant for 10 min.


Now i have gone out and bought a huge sythe ninja rev b, with the included 12cm fan.

I have the fan positioned so that it clows through the heatsink and directly at the fans that exhaust the warm air.

Ive also bought 2 addtional 22 cfm 8cm fans. Now the computer has a super huge heatsink, 12cm fan on heatsink, 2 x 8cm fans exhausting and 2 x 8cm fans on the intake.......its gone hotter!!!!!!!

I just dont understand!

with the added upgrades.

CPU on idle 59c.
50% load 72c

10 min cpu stability test (everest) 82c - 100% cpu
30 min cpu stability test (everest) 86c - 100% cpu, but around 50% cpu throttling.


Any ideas how i can get the cpu's temps down??

When playing tomb raider it gets hot, and slows down... probably because the cpu is throttling.

I did want to overclock it but i dont think theres much chance of that!

Bad mount definatly, does the heatsink feel hot? I doubt it, reseat it, make sure it makes good hard contact, and make sure you use good paste and not some cheap unbranded goo.

Even with the old intel stock coolers the cpu's never hit above 70 C in the prescott pc's I built, I think you either have bad mounting, or some seriously dramatic airflow.

75 C is the limit usually, 65 people recommend as a safe limit for overcloking, although i had my 3 ghz @ 3.9 ghz @ 73 C very often under 100% load, yet it kept working for ages, in the end I just sold it, this was on a very poorly mounted zalman 92 mm flower something ( very poorly as in carp paste that was completly dry and evaporated when i removed the cooler after a few months), so check your paste and mounting.
