like the title said im getting 90c while gaming in games like heroes and generals.pubg. and dota 2.
case its not mencioned because its not gonna help. its generic .its one of those mid tower office pc.(it has 1 tiny 6cm fan)

the cooler its stock.(already check its not bad mounted). it has a white thermal paste puchased for 1 dolar.but they told that kind of thermal paste was for pemtium computer. dont know

should i buy and test something like a artic o thermaltake thermal paste. or going directly for an aftermath cooler?

So 85C with the side panel open with stock cooler and stock clocks. I would consider getting some Arctic Silver 5 and doing a cooler re installation after properly cleaning off the old paste. With an Intel stock cooler I'd aim to keep things below 80C under load. I'd also dust the case completely and clean the Intel cooler grills.

I'd also invest in some more fans. If you drop 5C with the side panel open then you need to get some more air flow happening in that case. It's not just your CPU at stake, your graphics card and hard drives all have reduced like span when operated at hot temps long term.

After all that if you aren't below 80C then I would get a cheap aftermarket fan such as a Cryorig H7 or a Hyper 212 EVO. These coolers...

The stock cooler is performing about where you'd expect it to, the paste will make next to no difference, what you have is a problem of airflow, the cooler doesn't have enough fresh cool air to work with, you need to get at least one 120mm fan as an intake an at least one 120mm fan as an exhaust. Nothing else will make much of an impact.

asking airflow to my case would be something close a miracle . do you suggest aftermath cooler like cooler master 212 . or a new case with like you said 12cm fan?

If your cooler is mounted well, I expect to see 10-15c. over ambient.
90c. under load seems high.
But, I would not worry too much.
The processor will slow down or shut off if it detects a dangerous temperature.
That is around 100c.

Your parts are not power hungry.
Any cooler needs a source of fresh air to do it's job, so your case matters.
Take the case covers off and direct a house fan at the innards. If that helps, look to case cooling solutions.

In case you need to remount your cooler, here is my stock instruction on how to do it:

----------------how to mount the stock Intel cooler--------------

The stock Intel cooler can be tricky to install.
A poor installation will result in higher cpu temperatures.
If properly mounted, you should expect temperatures at idle to be 10-15c. over ambient.

To mount the Intel stock cooler properly, place the motherboard on top of the foam or cardboard backing that was packed with the motherboard.
The stock cooler will come with paste pre applied, it looks like three grey strips.
The 4 push pins should come in the proper position for installation, that is with the pins rotated in the opposite direction of the arrow,(clockwise)
and pulled up as far as they can go.
Take the time to play with the pushpin mechanism until you know how they work.

Orient the 4 pins so that they are exactly over the motherboard holes.
If one is out of place, you will damage the pins which are delicate.
Push down on a DIAGONAL pair of pins at the same time. Then the other pair.

When you push down on the top black pins, it expands the white plastic pins to fix the cooler in place.

If you do them one at a time, you will not get the cooler on straight.
Lastly, look at the back of the motherboard to verify that all 4 pins are equally through the motherboard, and that the cooler is on firmly.
This last step must be done, which is why the motherboard should be out of the case to do the job. Or you need a case with a opening that lets you see the pins.
It is possible to mount the cooler with the motherboard mounted in the case, but you can then never be certain that the push pins are inserted properly
unless you can verify that the pins are through the motherboard and locked.

If you should need to remove the cooler, turn the pins counter clockwise to unlock them.
You will need to clean off the old paste and reapply new if you ever take the cooler off.

so i would hit 70 with the 212x. and less with proper fans?

do you suggest aftermath cooler or new case with more fans.

is this overclocked? 90 seems abnormal to me. what are idle temps, they should be in the 30s.

although you say it is seated probably, i would take the mobo out of chassis, inspect closely the HSF installation. and regardless i would thoroughly clean cpu and heatsink and reapply TIM according to specs IE) very very thin layer!

90c is too hot even for a stock cooler under load at stock clocks. Uninstall the cooler, clean the paste, reapply the paste, and reinstall the cooler. If you want detailed instructions on this we can provide them.

If you are overclocking, revert all overclocks until you have a better cooler. Intel coolers are not designed for overclocking.

If temps don't improve, open the side panel of the case and see if they do. It could be an airflow issue.

If that doesn't help, replace the cooler with an aftermarket one. Cryorig H7, Coolermaster 212 EVO are cheap coolers, outperform the stock coolers, and are afforable at under $40 USD.

Ok, so then you have a cooler problem.

- Remove cooler. Clean all old paste off with isoprobl alcohol 90% and a lint free cloth. Clean CPU cap until it shines. Apply a small vertical line of thermal paste on CPU, then mount cooler. Plug into CPU fan.

- Clean the cooler with compressed air as well as the PC case. Try running the PC with the side panel removed.

If you still get CPU temps in the 90C area then replace the cooler although cooler replacement should not be necessary to get temps below 90C on an Intel stock cooler unless it's not working properly or badly mounted.

well .the cooler has been already clean and dismounted and remounted like 2 times .

Assuming the installation has been performed correctly and you get 90c load temps, see if the temps are lower with the side panel removed. That will tell you if you have an airflow issue.

If that doesn't drop temps down below 90c, replace the cooler with an aftermarket model like the Cryorig H7 or 212 Evo.

We have some missing information.
1. What is your ambient temperature.
If it is 20c. then 45c. at idle indicates a problem.
If your ambient is 30c. then 45c. is ok.

2. Can you provide a link to your case?
Or, at least a photo or description of what the fan arrangement is.
Without that info, I have no idea if your case is supplying sufficient air for the cpu cooler to do it's job.
Even the best coolers can not do the job if your case only has a dinky 80mm exhaust fan like the old cases did.

3. Humor me with a few checkpoints on mounting the cooler:
a) How much paste did you use? If it was more than a rice sized drop, you used too much and it is acting as an insulator.
b) look at the back of the motherboard. Can you see all 4 pins through the motherboard and locked?
c) If you nudge the cooler, does it wiggle?

The stock intel cooler is a very simple device.
Nothing can go wrong with it.
If the fan spins you should be good to cool a i5-2500 adequately.

it has space for 2 8cm fans . but it have one installed.it have also a white thermal paste. but they told me "thats for old pemtium" . so i took it off .

1.ambient temperature is 21
2.it have space for 2 8cm fan at the back. it has 1 installed
3now it doesnt have paste. it has a white thermal paste that i put months ago but until now it only has managed to decrease like 4 o 5 degrees

c.i believe its very well adjusted. it doesnt wiggle if i try to nudge or take it off

And what did you replace it with?

And to quote myself:
The stock cooler is performing about where you'd expect it to, the paste will make next to no difference,

http://www.tomshardware.co.uk/thermal-paste-comparison,review-33969.html - as you can see there is nothing in it, so your shop doesn't know what they are talking about.

The answer is really simple, there is not enough air flowing through your case, you need better airflow in your case, more intake than exhaust, intake at the front, exhaust at the back. You MUST run with thermal paste.

It would really help if you read the suggestions instead of just doing random things which will make it worse.

i think i have only 2 options
1.buy a second 8cm fan and put it on the back, and other 8cm and put it in the case cover. so it blow air to the gpu and cpu

2. or just buy an aftermath cooler.something like a hyper t2,t3,t4 or deep cool 300

Did you try removing the side panel of the case and seeing if that helps with temps? That would give you information (airflow) instead of guessing buying PC parts.

Also even if you have the best CPU cooler if you have no thermal paste the CPU will overheat.

i found out that i have thermal paste.i will try the side panel idea.
