Cpu temp questions

Cpu temp questions please read

I just installes a new heatsink and fan on a amd athlon xp 2500+ 1.84 ghz . the idle temp before was 34 now it idles at 45. It runs well however should this temp be a concern for this chip? I used a cooper heatsink and artic silver5. Most of my computers i can get to idle at 35-39.
I also have a new P4 3.20 that no matter what I do it idles at 54. It is running vista mone basic if that matters. Should I be concerned about this one?
Can anyone direct me to a free site that I can run a program to see these temps at high load? Thank you

You're sure that the heatsink is fully seated and you didn't use ridiculous amounts of the thermal compound?

Heat dissipation is also greatly affected by heatsink fan speed/air flow.

Is the new fan slower or setup differently in bios or connected differently?

The new fan runs slower

are my temps too hot for these cpu's? How about the web site to test temps at full load?

The P4 is not too hot - if that is the Prescott, it will throttle at about 72 C. In fact, most Asus boards supporting the 775 P4 have a lower thermal target of about 50-52 for the Q-fan operation (fan runs slower until temps rise and the target temp is 52 C, so at idle doing little the fan is quieter).

I have no knowledge of the AMD issue.

Those temps aren't too bad, and this may seem stupid but you need to check the simple stuff too: is your heatsink clean? I get mats of dust that totally block airflow and will raise my idle temps for my FX-62 from 35-40C to 50+C. And is the P4 *ALWAYS* at 54C? as in no change what-so-ever (even if you open your case and put a fan on it etc)? because that could just mean the temp sensor is shot.
