I have a pentium D 2.8 processor and it runs way too hot at idle temperatures! It's around 65C when idle and when I surf the internet and such, it goes up to 70C+.
I changed my heatsink already and applied the thermal paste correctly so I don't think it's the heatsink. I believe the problem lies within the cpu itself because I installed a celeron D on the same motherboard and the cpu stays around 40C when idle.
What do you guys think the problem is?

Now I assume that the temp used to be lower. The pentium d was one of the hottest running processors that Intel had (very high power consumption). That being said it's possible that you may have a slow running fan.

Something that you may want to check, is the voltage supplied to the CPU. Too little power may cause crashes, but too much power can easily build up excess heat. The proper voltage should be between 1.2 to 1.4, so choose the lowest voltage that keeps your system stable.
exTI is right in the fact that it runs hot. That chip is rated at 95 watts dissipated. That's a tremendous amount of heat for any CPU cooler to pull away.
Is it possible for you to open your case and have another small table fan or something similar to blow on the CPU? Even a clip-on fan you can get from your local drug store will suffice. Or, would you care to go the route of upgrading your CPU cooler to something more "extreme"? For example, in one of my desktop machines that I built, I bought a Zalman CNPS 7000 Copper cooler which is the size of a softball and weighs almost 3 pounds. Heat is not an issue for that machine. You can see it here if you wish.
The maximum temperature for your core should not exceed 63°C, so 70° is very hot. Good airflow is very important.

Thanks for the fast replies.
Well, I tried to change the voltage in my bios, but I couldn't find it anywhere. I installed a program called speedfan and it says:
+2.5: 1.25V
Vcore: 1.34
+3.3V: 3.25V
+5V: 5.19V
+12V: 12.11V
Fan1: 1739RPM
CPU: 62C
Local: 41C
Remote 2: 44C
Also, the heatsink in my computer isn't the intel one. I already changed it to another one, but maybe this one isn't that good? Should I invest in that zalman? I don't want to buy it, and then it doesn't work still.
Well, prior to me changing the heatsink, the temperature sometimes rose up to 100C and my computer shuts off. It did that A LOT before and I was naive to keep using the computer until I figured out that this was way too hot! Also, the temperature when I first got it were in the 40's.
Another thing I should point out is that when I check the temperature in bios, it starts off at around 64C and rises up to 82C.

have you tried a new fan?

| What do you mean? The fan the blows the hot air out? The heatsink?

I made the assumption like most cpu chips, it has its own fan. But if you have a dell or hp they like to use a larger fan with a large shroud for all air flow. Does it make any difference in temp. if you leave the side off the case? Could it be the intake/exhaust air vents are being blocked?

Just thought of something else. Look in bios and see if there is a way to run the fan at max. There may be a setting for auto or quiet. It may be a bit loud though.

| Well I changed the fan for the cpu because the stock one was overheating my computer to the max. If I leave the side open, it doesn't make a difference at all. I'm using a program called "speedfan" to run my fans at max speed.

Just a word of caution here...
I use Speedfan on my network's XP Pro machine. It's probably one of the greatest pieces of free software a computer geek can appreciate, but...be careful of the temperature threshold you set them at. Too high of a temperature setting, and the fans will slow down and things get hot inside. Not good. If you want the fans to run at full speed all the time, make sure that the "Automatic fan speed" option is un-checked (unless you know what you are doing) or you're asking for a hot CPU and Northbridge. Keep all fan speeds at 100%.
Speedfan is great in keeping the fan noise down to a minimum, but it could also be your machines worst nightmare with the wrong settings.
