CPU has extremely high idle temps

[MadDog390]

This is my first time building a pc and when i booted it up, the cpu was running at a constant 95 degree celsius temp without any utilization at all. It's an AMD Ryzen 9 7900x and the AIO is CoolerMaster MasterLiquid ML240L.

Cooler don't work then, something not plugged in or no contact (did you remove the plastic sleeve on the cooler block ?  )

Its built for that Always boosting to maximum freq till reaches 95c.

 

You can enable eco mode for a modest drop in performance but temp benefit.

 

Is it actually idle?

I removed the plastic sleeve on the cooler block and also put the thermal paste on it. And the utilization for cpu showed 1% while the temp was 95

Try to disable PBO or disable any oc you have enabled as well as hard cpu ratios

There is something wrong with the cooler then. Are you sure that you didn't mix up the RGB cable with power cable ? are fans spinning ? 

btw imo 240 AIO might be not enough for 7900x under full load but on idle temps should never hit 95C

Try resitting the heatsink and check the pattern of the paste on both surfaces for anything obvious
Also as others have said the pump should be spinning and ramping up quite a bit if not maybe its not in the right header 
Most often the correct header is located in the vicinity of the cpu and will be labeled accordingly

So, i just opened the heatsink and this is how the paste looks

And this is where I put the cooler header

This is where i put the cable for the cooler. Also which aio do you suggest for 7900x?

Ah. Its fixed now somehow. The idle temp is 40 celsius which Im hoping is good. Thanks everyone
