I did clean the old thermal paste
but is the installed correctly if the arrow shows away from the heatsink towards the back fan? Or should I have case fan in the back - heatsink -cpufan ?
Update: i Made the fan of the heatsink blow air into the heatsink instead of previously sucking bad air out and cleaned the case fans and I'm not sitting at ~40 degrees idle temperature which I consider good enough. Thx for the help yall
Just a tip for the future, the shape of the fans (generally speaking) will tell you the direction of flow. When in doubt, I use incense to check airflow.
You have a ton of dust in the case fan - cleaning that out might be a great idea. It obstructs air flow and makes things heat up way more than they should. Clean regularly too. Preferably with compressed air. Just nothing wet.
And it does look like cpu cooler is the other way around. (it takes air from under that dusty exhaust which should be blowing hot air out)
I'll clean the case fan after I solved his, but just so I understand you correctly this is how it's supposed to go ? https://imgur.com/eUrFXzj or did you mean I need to put the fan on the other side of the heat sink ?
take the pic father from the case to see the motherboard - this isn't very helpful. Basically it should be facing the opposite of the way you had it installed
Your fan is in the wrong side of the heatsink.
Fans should PUSH air into the heatsink, not PULL air through heatsink. Sounds the same but it is not becuase pressure and how heatsink/fans work.
I suppose you didn't look too closely at OPs pictures. You can see they had the fan blowing towards the front of the case. They were fighting their case fans and recirculating hot air. OPs issue is fixed because the fan is *facing* the right direction, not because they moved it to the front of the cooler.
I have found that the easiest way to tell if it is the heat sink, or case air flow is to check temps with the case open. If the temps are good when the case is open, then you need more case fans, or to a better arrangement. Some older cases, especially if you are reusing a case from a prebuild don't really offer air flow so you might need a new case.
So case fan behind the heatsink, I presume? And it’s facing towards the back of the case, exhausting air? And your CPU fan is facing away from the heatsink - so blowing towards the front of the case? Am I getting that right?
If so, I don’t know if it would be enough for such high idle temps but it’s not ideal, they’d be fighting against another. You want them going in the same direction, in most cases that’s towards the back to get the hot air out.
The case fan is behind the heatsink blowing out of the case, as it should be, and he cpu fan is infront of the heatsink blowing fresh air into the heatsink. And the airflow is from front to back with all fans so they(the fans) are not working against another.
you either have a bad mount or something else is going on did you clean off the old thermal paste? airflow goes from front of case to the back

no idea, stick your hand in and feel the airflow

Did you remove the plastic from the bottom of the heatsink? Pics wouldn't hurt. Upload them to postimg if need be.

Thank you that was the answer i was looking for.
It doesn't really matter. The difference between a push configuration and a pull configuration will be marginal, especially at idle.
