CPU Is Burning!

Good afternoon,
This morning when I tried to turn on the PC, it went off after a few seconds, without showing any video signal in the meantime it was turned on, and iterating this process by itself to infinity (it turned on and off after 5-10 seconds) . Assuming it was the video card I disassembled the PC and tried to turn it on, but it gave the same problem, so I switched the RAM between their slots, and everything seemed solved (even with the video card mounted). However, I turn on the PC and immediately notice a difference: the CPU (I7-4790K @ 4.00GHz, cooled with the Enermax Liqtech 240 AIO Liquid Cooling) shows in idle the temperatures that I used to observe in long sessions of gaming, suddenly and senselessly bouncing even to 100 degrees.

I used HWMonitor to monitor temperatures and these are the results:
45-70 ° C in idle;
80-100 ° C in gaming, observed with a one-minute long session on Minecraft.

Everything was fully functional until yesterday, with temperatures of 70 ° C in long gaming sessions (even 10 hours, between me and my brother), idle temperatures of 28-35 ° C degrees and a power consumption shown in HWMonitor of ~ 18W (now it reaches 28W).

Please help me out :(

Personally, I think your pump has died a death and stopped working. Is it very old? Is it still under guarantee?
The water isn't moving and so just gets hotter and hotter.

just to say, make sure you have plugged ALL cables in to make sure the pump is plugged in as mentioned above by someone else.

I just checked and actually the pipes are very hot, not too much, but definitely not fresh. I had also tried to disconnect and reconnect the pump, but the result had not changed. The pipes are as hot as the top of the waterblock, if not more (while running in idle with 50°C).

I imagined it, it was the first thing that came to my mind this morning. However I disconnected and reattached the pump for safety, and in any case this has an LED that indicates whether it is working or not, and the LED is on, so the only solution is that it is dead. Oh, and i just checked that my warranty has expired just 2 weeks ago...it was waiting for me :(

What do you think about this part?
 


You can still claim on warranty if you speak to them.
They are normally not idiots and you can sort of be polite about how typical it runs out after 2 weeks of warranty and you would think their products would last a lot longer, Also things like, do you expect it to run out immedietly after warranty and things like that, it does work. Well it worked with me and my Steel Series which was 2 months out of date :)
