Got some interesting cooling issues.

The past 6 months i have been having issues with my heat being high in the CPU 6 months ago it reached 105 degrees celcius and shut down, so i cleaned it and it bumped down to roughly 85 degrees working temp. For a month now it has been at 100 degrees (even in idle) and throtteling everything. I could play but with some performance limitations. (even if it was newly cleaned). I tho id try to replace the thermal paste since the pc is closing in on 4 years of age and it was a very thin layer of paste so removed the old paste and applied some new. Now the throttle is worse, so much that even the browser can lagg.

GPU temp is roughly 50 degrees
CPU Power is roughly 19-22W at all times.
VID 0.7-0.9 V
CPU Fans is running at 1650 rpm (and i can see them spinning)
One tube from the CPU feels hot
One tube from the CPU feels cold
Feeling on the heatsink i can feel vibrations and the same with the tubes.
There is no "new product" plastic on the heatsink (between cpu / heatsink)
The heatsink is screwed on tight, in the same direction as it was bought. (was a pre-assembled complete computer when i bought it)
The temp more or less instantly goes to 100 degrees on bootup even after it has been off for a while. (lowest i have seen it is 80 degrees)
Using core Temp and HWMonitor to get this data.

Got a corsair-hydro-h100x

Is the radiator cold to the touch or is it luke warm?

That's a sign the pump on the AIO has failed. Either that or you have cavitation. Perhaps source(borrow, not buy) a beefy air cooler and see if the temps are at a manageable range, if they are, that would mean your AIO has conked out.

What BIOS version are you on for your motherboard?

Prior to the creation of this thread, how were your temps for the CPU? How is the AIO mounted in the chassis? Speaking of chassis, what is the make and model of said...

Chassis is called taurus gaming pro:

I just downloaded the most recent bios version and is in the process of updating that.
 
Prior to the thread (the temps have been at roughly 100 for a month, but it seems like there is a heavy increase in throtteling lately since it has gone from being able to play games even att 100 degrees, to barely being able to have a browser/discord up)
 
If im not mistaken im seeing 2x LEDs lighting up on the motherboard that i cant remember being lit before, Two orange LEDs at the front of the chasis (backside is where u plug in external power, USBs, HDMI etc) one at the top and one at the bottom
 
The fact that the two tubes at the PUMP are at DIFFERENT temperatures tells me there IS water flowing around the loop.

I have two suggestions.
1. When you re-did the thermal paste, how much did you apply? You mention the old was "very thin". It is SUPPOSED TO BE. Too thick a layer there slows down heat flow. Look up instructions on the 'net for how much to apply for YOUR CPU. Often it is only about one or two rice grains' worth.

2. Corsair does something unusual in its AIO control software, iCUE. That has a place where YOU can set the PUMP speed. (Most such systems are designed to keep the pump at full speed all the time.) You can use this option to customize performance according to how you use your system and how much heat it generates. Do NOT go changing it frequently. Use this as a way to set an optimal "range". Set it so that at MAX workload and heat generation, the RAD FANS are running fast but not at their max speed. (Unless, of course, the fans do run max speed at max pump speed.) From then on the rad fan speeds will simply be auto-adjusted as workload changes, but the system CAN deal with max heat load.

was so thin that there was several blank spots :)
I switched out the AIO and them everything worked perfectly! Thanks for your response :)
