CPU temp rising constantly to tj max(85c)

Specs: Windows 7, intel dual core e 2160 1.8ghz 1 gb ddr2 ram
Hello everyone
my CPU temperature keeps rising and rising until it reaches tjmax(which is 85 c) .i use core temperature to determine CPU temperature and its reading is always more than the BIOS temp. reading
i think the problem is my PSU fan because it is not working properly
it doesn't even start automatically at start up i have to manually start it (using a pencil or something) then it starts and runs very slow
my CPU temp at standby is 50-55C and whenever i try to do something it reaches at 60-65 (often at 70) if Psu fan is not running
if it is running (as it is now) temperature is 50-55 (current temp as i type,,, is it right as i have a Intel dual core e2160 1.80ghz) my CPU fan is perfectly fine and my power supply too just PSU fan is not working
if it is the problem is there way to change only the PSU fan not the whole power supply
please help
thanks in advance

If your PSU fan is the only exhaust fan in the system, then you have to replace or fix it. If possible, you can purchase one at Newegg.

From what you said, it seems that dust has found it's way in the fan's bearings, thus causing it to run slow/stop. So, you can try oiling the fan bearings. Check out the link below:

Here is how you open a PSU. Note that you don't have to completely unplug the fan so as to oil it.

Important: Read the warning that are issued in the link above.

Keep us posted.

While the PSU fan problem will have to be dealt with, I doubt it's the reason your CPU temp is so high.

"my CPU fan is perfectly fine"

Maybe, maybe not. Proper heatsink installation is critical. Did you apply the thermal paste correctly? Here's the instructions:

That was about to be my 2nd suggestion.

my CPU temp at standby is 50-55C and whenever i try to do something it reaches at 60-65 (often at 70) if Psu fan is not running

If this temp difference is caused by the PSU fan, then the PSU fan need to be dealt with when possible.

Replace the power supply, you can get a decent one for not that much more money than the fan. This one is $25. after the rebate:

And a fan is what... $6. to $12. or more.

Install HWMonitor and get not only the temps but the fan speeds as well. A valuable tool in evaluating why you are getting hot.

If you want to know now if it is the lack of hot air exhaust from the power supply fan that is doing it (before even changing it), open the case and have a small portable fan blow air into your case. If it is still hot, you still will need to change or repair the power supply, but you have another problem. If the temps stabilize, then it is that your system relies heavily on the power supply's fan to keep your case cool and that may be enough to fix the problem. Personally, I would in this case, add or upgrade your rear case fan to improve air flow and keep it cool as well as replace the power supply.

If the system is on its last leg and you are planning on replacing it soon, do not spend too much on it, but the power supply I listed would be a good base for later building a decent machine as would decent case fan always be useful.

You have to be a little bit crazy to keep you from going insane.
