Since moving my computer to a new case with a new power supply I am experiencing massive Fps drops!! The cpu fan is also running full speed.

I'm not massively knowledgeable on computers but can anyone help? 

My specs are:

Intel i7-2600k 
16GB HyperX Ram
1 TB HD
Nvidia GeForce GTX 1050ti 
Corsair 650w power supply.
The CPU cooler is the stock cooler that came with my computer, it's for an alienware aurora r3.
