So i got a new cpu stock cooler (for my i5-2400) and i've installed everything probably correct
And i check idle temps and its bouncing from low 40's to high 60's
is there a fix for that problem?

P.S My gpu seems to be fine at idle (30c)

Specs

i5-2400
Gigabyte H61M-S2P-B3
Gtx 960 2 gb (asus turbo)
8 gb of ram

Likely, you did not install the stock cooler well.
At idle, you should see 10-15c. over ambient.
Check the back of the motherboard, all 4 pushpins should be through and locked.

You will need some thermal paste to remount it since you should not try to reuse what was pre-applied.

A poor installation will result in higher cpu temperatures.
If properly mounted, you should expect temperatures at idle to be 10-15c. over ambient.

1. But is it in fact idling ?

When you start your PC, arrive and windows and you are sitting there doing nothing, that doesn't mean that your PC is doing nothing. If you monitor CPU speed thru the entire process, you will see that:

a) In the BIOS, your CPU is operating at full speed as rge CUs down clocking features are not initiated until you arrive in Windows.

b) Once you do arrive in windows, it can take 2 - 5 minutes for the CPU activity to 'chill" and drop down to idle speeds.

c) When testing, I would suggest running HWiNFO (sensors only) and placing it on the right side of screen, extending the window from top to bottom so you can see as much info as possible. Watch the CPU speed ... right after boot mine sits at its rated speed (no boost or OC) for a bit and then drops down to 800 Mhz. I wait about 3 minutes after that to record idle temps.

2. The stock coolers come with a pre-applied thermal pad, so applying paste isn't necessary. But if you re-used another cooler,make sure that cooler is appropriate for that socket and that you cleaned the base and CPU thoroughly before properly applying new TIM.

----------------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.
