I have 3.2 ghz p4 now, and temperature is around 80 c if I open tabs, normally around 67. Also I have 2.8 ghz, with that temperature is around 40 c. Maxtor hdd's temperature is maximum 42 c
.

For example if I open a lot of tabs or videos, ram goes low and computer starts not to respond and maybe a few seconds freezing. I will buy 1 gb ddr ram or more to solve this problem but what about cooling? IS that cooler necessary ? What will I gain if I use 3.2ghz instead of 2.8 more than having high temperature, I cant see any difference maybe because of 1.5 gb ram.

Should I buy new rams or new cooler or use 2.8 ghz?
 
Pentium 4 systems tend to run hot but yours needs to run much cooler. I would remove the cpu fan, clean off the paste from the heatsink and then reassemble with new paste. Read up about how to do it and apply new paste between the heat sink and cpu - not too much and not too little. You can buy small kits quite cheaply (eg on eBay). Take your time on this, do a good job and things should run far cooler. If the temperature doesn't drop substantially try again.

It's just possible that the fan is clogged with gunge or that airflow is restricted in the case so check that out first.

The Arctic Cleaner kit I had in mind has two plastic containers of fluid to prepare the heat sink, some cleaning towel and Arctic Silver 5 paste plus instructions. You can stick extra fans inside the case but it's air flow through the case that makes the most difference.

Ram installed will depend on the OS and what you use the computer for. I'd suggest 2Gb is adequate for XP 32 bit.

Aim for a temperature around 60c for the cpu. I worry when my P4 gets over 70c and so I don't use it for cpu intensive activities like gaming or video editing. It's been in regular use for 9 years.

You would perhaps do better to save for a modern system rather than splash the cash on the one you have.
 
Yes I would like to buy a new modern next year, but probably I will buy a laptop, not a desktop so I need this computer , I will left nights open.

Temperature was 60 64 c with a few tabs open, I opened 4-5 more video tabs and now it is 80 c.

Rams cost around 20 30 dollars, with that money I cant buy any used motherboards that support core cpus or ddr2 ddr3.But I spent too muchg money on this stupid system. 1 gb ram, 1 cooler,fx5500 gpu,a psu. Maybe I could buy a better system with that money
 
The temperature problem, Maybe it is because, my case fans can not make its work. It is stock fan, behind. And no more fan. And case is surrounded tightly, just a few cm s from sides and 5-6 cm s from up. And I took off case side parts.

Inside case

case outside, same dirty

I changed its location to left after taking picture the place of external haddrive and sound power machine in the picture, Its back is open and sides are now free. But not much changed.

What about putting the fan in the reverse position in the back of case, you can see in the picture, so it can blow air inside, now pulling air but there is warm air to be pulled?
