Overheating CPU due to failed Water Cooler?

I recently purchased a build off someone.
i7 5820k
x99s sli plus
geforce 9800 x2

I booted it up and it was slower than hell with simple tasks. I made sure all the drivers were installed properly and still it was sluggish. I was letting it run for a while and realized the water cooler stopped running. It has an interesting water cooling system. It uses the Bigwater 760 plus attached to a Larkooler fan system.. definitely some custom work. I traced the cables and saw that everything seemed to be plugged in correctly, and the Thermaltake fan on the Bigwater 760 is lit up but not spinning. The Larkooler system and fans located at the top of the case are running but no liquid is being pumped through, because it all runs off the 760 pump. I should add that the pump was working a few days ago, but the computer was still just as slow. I'm having a bit of trouble finding the root of the problem. When i go into BIOS it reads that the CPU is 97°C which is insanely high. The CPU has also been locked at 0.8Ghz, no matter what the task is. So if anybody could shed some light on why the CPU is locked at that frequency as well as the issue with the Water Cooler, I would most appreciate it.

  1. The pump is dead or it's running low on water. The CPU is locked at that speed due to thermal throttling.

    If it's been like that long, the CPU could be damaged.

    Are you sure it's using 2x GTX9800s? Those cards are ancient. A modern 1050 Ti would be faster.

    That would explain some of the performance issues you're seeing. Not only are the two cards in SLI slow, but you'll also have all of the compatibility issues associated with SLI.

    You should get a new CPU cooler, perhaps an air cooler, and get whatever GPU you can currently afford. If the CPU has been damaged, you should be able to tell once you have a new cooler installed by running the CPU torture test of your choice. Most have some form of integrity check.
