im sure if i had the time id find the answers im looking for but i dont have the time to search it. recently did my yearly flush and fill. after i got it all back together i noticed idle temps in the 30c range and while i game 70-80c.  i know these cpus are known to be a tad hot but i dont remember the temps being  this high before hand. Im trying to determine if i need to drain the loop and redo the paste or am im in the ball park for this cpu. sorry if this seems noobish but ive been worried about this. 
 
 
System specs: MOBO: EVGA Classified Z-690
CPU: i9 12900k
GPU: EVGA XC 2080ti 
RAM: Corsair Dominator 6000 ddr5
PSU:EVGA Supernova 1300
 
Cooling system: (2) EKWB Cool Stream 360mm rads.  dont remember thickness. 
cpu block: EKWB Velocity 
res: singularity computers Protium pump/res co,bo
coolant: XSPC EC6 opaque red
Tube: monsoon PETG 
Gpu block: EKWB vector
Fans: Noctua NF-P12x6
case: Fractal Design Define S2
 

Figured it out. It’s a cross between 12th gen and the fact my case isn’t really efficient for my lay out. With the added 360 rad on top there’s no room for a rear case fan. Mounted one on the exterior(Jank I know) and temps became manageable. This this is the true definition of a space heater now

Front rad is intake too rad is exhaust.

I can’t delete responses. And I’m on my phone. On my end it sent that reply three times. Can some one get rid of the other two please

 I'll cleanup the triple post
 
Couple of other ideas:
Make sure all the air works its way out & is not trapped in pump

Pump & fan RPM
 
clean fans & screens for best air flow
 
EK CPU block, have to be plumbed correctly for best cooling (ports are marked In/Out)
 
Voltage settings in BIOS can impact CPU temps a lot
 
Your room temp is possible much warmer than before, if it is summer time in your part of the world.
