The motherboard name would be much useful, as that is what determines the fan speed and power. I'd try to check the BIOS settings to see if there's anything concerning fans behavior at shutdown

In the motherboard BIOS, can you find any option, looking in every menu, concerning fan behavior at shutdown? Also, can you confirm that the fans never stop after you shutdown the PC or does it just take a couple minutes or so?

well i did it once i did a shutdown after 8 hours they were still working

Ok, I see; what about the BIOS options?

[LionSpeck]

Also, what brand and model is your PSU?

[zivisnotziv]

Thermaltake Litepower GEN2 450W

and in my bios i didnt see anything not ok

From my understanding, the fans and LEDs stay on because either the PSU keeps on giving power to the 24 pin connector to the motherboard even if turned off, or either the motherboard doesn't give the PSU the command to turn off. Can you try and reseat the 24 pin power connector of the motherboard?

[zivisnotziv]

how do i reset it

[LionSpeck]

To reseat it, just unplug it and plug it back in

[zivisnotziv]

that will take a while cause i have to open the case but does it have good chances to work cause when i turn off the pc the fans are working but at lower speeds

It may work, I can't say for sure; the reason for the fans' lower speeds may be because the CPU is turned off and its temperature is near ambient: this is, if the motherboard doesn't turn off. If it does and the problem is the power supply, which does not receive the command to turn off, it's because the motherboard isn't giving no more PWM signal to control the fan speed, so they work at their lowest speeds. Either way, I'd check the 24 pin connector to be sure there's no false contact or dust that can cause the issue

thanks ill check it 

[zivisnotziv]

so unplug and plug to try and fix it ?

[zivisnotziv]

Anyone else suggestions pls i need more before i try them

Two suggestions:

1.) Update the BIOS

2.) (Assuming Windows 10): Start > Settings > System > Power & sleep > Additional power settings > Choose what the power buttons do > Change settings that are currently unavailable > un-check "Turn on fast startup" then click "Save changes" and try shutting down to see if the issue persists.

i did the second option already and didnt work how do i update the bios tho

and does it have any risks with it
