CPU core temperatures

First of all Hello!

I Have Intel Pentium E2200 core 2 duo
running at its standard speed/not over clocked speed

my problem is that few moments ago my pc video card was running at temps 60-65C
with load and 40-55 in idle so i was getting worried in getting my video card fried so i off my pc and started removing the video card and cleaning the fans of it

after cleaning it i decided on cleaning the CPU fan( the fan that is on the top of the processor ) but i cant access the sides so i removed it and placed it back after it i opened my pc and started at doing my games ( i opened 2 wonderland online windows) and it consumes 100mb of ram each when i started it suddenly my processor temp gone into 60-80C" usually it was 45-50 C" so i turned off and made sure that my cpu fan was placed perfectly it was placed perfectly so im inquiring here on what to do with my cpu temps should i buy cooling fans that can be put additionally inside/outside ?
btw cpu idle temp after cleanin was 37C"
before cleaning it was 40C"

Sounds like the cooler didn't seat properly and/or too much heat sink compound. Remove, clean and reinstall is the first thing to do.

When you put the CPU fan back, did you first properly clean all surfaces and use new thermal compound (one pea size blöp in the middle of the CPU). If you did not do that, your problem is normal.

@Gewb i did put it back properly and made sure it doesn't come loose or something

@whs yup cleaned all surface of the cpu and the fan as it was full of dust
thermal compound was still present in the surfaces but not sure if i should put more as its kind of dry or something like that

and its summer in our place right now so its kind of hot but not this hot in my cpu

anyway i've tried burn in tests and captured screenshot of speedfan with the cpu temps
was wondering why is it that its burning test doesnt increase my cpu temps but doing other things does increase it

EDIT: But playing wonderland online does increase everything in my CPU load=100% CPU temp=70-80C" before i cleaned my fan it was not like this

i didn't touch anything at the processor slot though just brushed it a little and made sure it was fully locked
i only touched my cpu fan

Anytime you remove the CPU's heatsink, you have to replace the thermo paste as the stuff that was there has been disturbed and may have developed gaps and air bubbles from using the old stuff.

Basically what happens is when you apply a new coat of paste it's soft and will melt into micro grooves and create a sealed surface. Now later on you remove the heatsink again and pull those sealed areas up - well because of heat and other factors the old stuff that was there has hardened and thinned out so now there's nothing there to fill to gaps you opened by removing the heatsink. Thus you'll now need to remove the old coat and reapply a fresh new coat to properly seal those gaps again, and thus get your temps back in line.

Hope this helps.

oh okay ill buy it somewhere in computer stores ill find some tutorials to apply it since i dont know how ( im not the one who assembled my PC) what kind of thermal grease should i get?

in cleaning the thermal grease remains should i scrape it up? including in the processor area as when i opened it there was dried grease in it

-thnx

How to appy thermo paste - Google

Best thermal paste on newegg? - Overclock.net - Overclocking.net

I prefer MX-3 but bear in mind this debate can rage forever. It's sort of like asking which soda tastes better

You can also get it at Radio Shack - e.g. Arctic Silver ceramic

I suppose. Just about any thermo paste will do. You just need to make sure it's good for use on processors as they generate a lot of heat.
