Heating Problem

[bhupendra2895]

Hi, my system is heating too much.

This is my system specification:-
1)Motherboard:- Asus P5KPL AM/PS
2)Graphics Card:- Palit GeForce® 9400GT Super+1GB (1024MB)
3)Processor:- Intel® Pentium® D Processor 820
4)Hard Disk:- Samsung 80 GB
5)RAM:- 1GB 667MHZ DDR2
6)Cabinet:- Intex(It supports two more fan, which I haven't installed now.)

Is this problem is being caused by graphics card or motherboard and processor are not compatible?

Currently, temperatures are:-
CPU:- 81 C(160 F) Fan Speed 4821~ RPM
MotherBoard 49 C(120 F)
Graphics Card 64 C(147 F)

one thing i know is that the whole solution lie in thermal paste/compound and its uniform thin spreading on the cpu surface.

Airflow is everything (well, unless you're using a liquid cooling system). (And I'll assume you're using the thermal transfer paste properly.) We can't see inside your box, don't know what processor or heatsink/fan you're using, can't see what your wiring layout looks like, etc. Sometimes it's just a matter of using a few cable ties strategically. Make sure that cool air can get in and that hot air can get out (and don't put the box in an area where the hot air is just going to get sucked back into the case).

How I can check thermal paste is there or not?If I would remove the fan above CPU then this would remove the paste between fan and CPU.So I guess I need to buy the paste and then I have to apply it.I don't know how much amount of paste I should use and how to apply?

This is making my system shut down whenever I do lot of computing task.Also my system gets restarted due to voltage fluctuation.

Is unexpected system shut down has anything to do with graphics card and smps(450 watt, 230 V)?

Don't take any action listening to americans. Don't take your heat sink out cause thermal compounds are not so easily available as there in USA.
If you know anybody who owns a computer shop or repair shop or anybody who works there then ask him. It comes free with every heat sink (some already applied, some need a apply). And the compound provided with one heat sink is sufficiently enough for at least three heat sinks. So probably have an extra one for you. They gave it to me for free.
Or search for "Artic Silver" on ebay. It will cost you nearly 900 INR and you can use it 100 times. 9 Rs, huh?

I'll have to assume that you're either blind or developmentally impaired. I am most assuredly not American, and that's easy enough to see even if you have images turned off in your browser.

And that you don't know much about troubleshooting problems like this one -- it is far easier to tie off cables, make sure ventilation ports/screens are clear, and physically reposition a box, then test after each change than it is to jump right to the least likely culprit and spend money you don't have to spend.

I did exactly all this today, all wires in cabinet are tied in one place and they don't interfere with cpu fan.Then I removed cover of cabinet and started my system, I played a pc game(to do some heavy computing) for 1 hour and my system didn't turn off automatically but temperature of CPU increased to 81 C then with cover of cabinet opened I did php programming in ubuntu and CPU temperature decreased to 73 C.I guess problem is with the CPU fan installation.

In your experience if I install one more fan (just like a exhaust fan) in cabinet than it will make any difference.

essellar, I had clearly seen that you are from Canada. But you interpreted my post wrongly. From "americans" I mean all those writers of several articles on the net on "how to apply thermal compound".

It's the common thing for Pentium D CPUs to overheat. My brother had exactly the same CPU (820d) and exactly the same problem few years ago. Cleaning your CPU cooler and some new thermal compound will make things better but it won't solve your problem entirely. The thing is that Intel shipped Pentium D CPUs with standard boxed coolers although they generate more heat. That's why (if you want to solve this problem once and for all) I suggest you do what my brother did, buy a new CPU cooler. He got OCZ Vanquisher few years ago and it's still working fine.

do you have any case fans installed? if it shuts down automatically and you suspect the psu, haver it tested.
