hi guys, i'm not the greatest with pc's so you will need to bare with me. i have a i7700k cpu with a H100i cooler, i am looking at overclocking my cpu so iv'e firstly done a stress test, my cpu has already been running hot recently without much happening which i was slightly concerned about when i did the stress test it was sitting at 100 percent load at like 85-90c it then went to 95 and the pc froze... i restarted it and haven't done anything but this has worried me even more. where do i go with this and what potentially could it be. thew RPM on my H100i never seem to go above 1900 even when really hot and at max load. I Also must add i feel like the pc has been way louder recently and goes really loud then quiet then really loud again and the same thing happens over and over.

Thanks any help would be massively appreciated.

Is the radiator dusty? Is the fan spinning? You said the h100i was running at 1900RPM, so the pump is running. Did you check the thermal paste? What do you have the CPU clocked to?
