II just got a Coller master masterbox 3.1 lite. I have a gtx 1050, i3 7100, 8gb ram, Corsair 550w psu, 1 tb harddrive, and a h110m-a MB. The case can only hold 3 fans. Do I have to worried about overheating?
With the components you chose you will not have any issues with thermal throttling. Thermal throttling is where your CPU or GPU will downclock or shut down to prevent damage. Typically, this is cause by a high overclock or a improperly installed cooling solution. Since you have a locked CPU and the 1050 is low power device, you are not going to be pushing enough power to get your components too hot as long as everything is installed properly.
For a low-power configuration like yours, it doesn't look like it would get too hot to me. The case isn't the best in terms of possible airflow, but I think you'll be fine
