Overheating i4790k, broken sensor or non-functional Corsair H60?

Problem: My cpu heat sensors report an idle temperature of 90-100C, I noticed the problem as I after restarting the computer mid-session noticed the fans going for full, this have to my knowledge never happened before. BIOS tells me the temperature starts at about 50C and then climb quickly to around 90-100C. My ambient temperature is about 26C. My pump is registred to work at about 4500rpm at 90-100C in BIOS. It is connected to the SYSFAN1 slot.

When touching the pump house it is not hot, not even warm.
When touching the tubes, one is warm but not hot, the other cold (ambient temperature).
When touching the reservoir it is ambient temperature except when I did my experiment of tapping and moving it around during the computer operating. Then it got warm, but not hot.

What have I tried?
I cleaned the water cooling from dust, fan and reservoir both. Had no effect.

I removed the water cooling trying to clear any eventual air pockets in the pump. Following instructions here rotating and tapping the reservoir in a higher position than the pump. I can hear the liquid move inside. Had no effect.

I tried to move an eventual air pocket while having the reservoir removed rotating it. This seemed to effect the temperature allowing me to lower the temperature from 90C to around 50C as long as I kept tapping on the reservoir and moving it. The tapping only works if the reservoir is unmounted. This is the most effective measure I have taken.

Motherboad: Z97-G45 Gaming
CPU: Intel i4790k
Cooling: Corsair CW-9060012-NA/BLK (believe this to be a Corsair H60)

I include some pictures of tests I have run after the problem appeared. The information is all from the same session.

I hope for some answers and how to proceed.
Thanks on forehand.


 
Solution
When it comes to the AIO cooler its 99%of the time its Dead and Cooler fault
if you have the stock cooler use that and check the CPU it will be cooler then now and RMA your AIO
Pump failure is pretty common. Especially after a few years. Temperature sensor failure is extremely rare.

The easiest way to test is just get a cheap air cooler and see if temps drop. You've done everything else you can to test without bringing it in to a shop or replacing parts. A replacement cooler is the cheapest test (cheaper than a diagnostic). Especially going through a store with a good return policy.

Instead of just getting a cheap cooler. You can get a decent replacement. Such as the Cryorig H7. It isn't very expensive but does a good job cooling.

Thanks for a quick response. I will go and look for a fan.
The one thing that is really puzzling to me is how the temperature could be changed by me tapping the reservoir/radiator package if the pump do not work especially since BIOS register the pump as doing 4500 rpm?

Thanks for a quick response. The computer in whole is appr. 3 years incl. the Corsair H60.
If I do not find a fan this will be my next thing to try.
 


I had the same issue with my H100i V2
if you shake the pipes some times it starts the flow of coolent result in cooling of CPU but not work always
In the end i have to throw my AIO and now i bought the Air cooler and so happy
