CPU Temps at 100 degrees Celsius

Two days ago when I turned on my computer, I tried launching Overwatch and all seemed fine until about a minute into the game, I believe my CPU started throttling and temperatures stayed at 100C. Even after I closed all my windows, the temperature would not go down until I shut the computer down. I have an asetek 550LC, a liquid AIO CPU cooler. When I touched the radiator, it was cold as metal, however, I could feel the tubes vibrating, so I thought the pump would still be working. The circle area over my CPU is burning hot to the touch. After doing countless hours of research, I am thinking of trying to replace the thermal compound. Is that the problem here? If not, is it the CPU cooler itself? An answer ASAP would be greatly appreciated.

Here are my PC Specs:
CPU: i7-6700K @ 4.0GHz
CPU Cooler: asetek 550LC
GPU: EVGA GeForce GTX 1070
C Drive: 256GB SSD
RAM/Memory: 4 x 4GB 2133 MHz (16GB total)
OS: Windows 10
MOBO: GIGABYTE GA-Z170X-Gaming 3

By the way, I purchased my computer on 2016's Black Friday, and it came with a 1-year part warranty. Even though it's only around 2-3 weeks past, do you think they'll still provide assistance?

Noctua makes fantastic coolers, top of the line but expensive. If you want cheaper, something like a Hyper 212 EVO is the AK47 of air coolers these days: Cheap, loud at max speed, and it just works. A pain to install though first time.

No graphics card seating issue I think would cause CPU temps that high. These AIO coolers are just janky and I've seen so many issues with the pumps not working that I've started recommending just getting a decent air cooler. Not only that but good air coolers out perform these AIO units. Only when you go to true liquid cooling with a resivoir and all that you get amazingly low temps, but it will costs you hundreds with required maintenance.

You can try removing the mounting screws for the radiator and giving it a bit of shake. Don't shake so hard it pulls on the tubing to the water block or anything. It could be an air bubble that's stuck in the pump causing it to vapor lock. Make sure the tubing isn't twisted or bent at any extreme angles. Try setting cpu fan speed to 100% in the bios just to make sure the pump is getting enough power.

If nothing improves then it's likely that it needs replaced. The pumps on the aio coolers aren't the most robust. No telling if they'll still cover it outside of warranty, especially since it's not just a day or two but a couple weeks past. You can always try contacting whoever you got the computer from if it was prebuilt or contact the vendor where you bought the cooler. Worst they can tell you is it's out of warranty.

Outside of brief testing after trying to work out air bubbles or forcing the cpu fan to 100% in the bios to see if temps are back under control, I'd avoid using the pc until the cooler is fixed/replaced. With the cooler no longer working properly it basically has no cooling so it will keep thermal throttling. Thermal protection will attempt to keep it from being permanently damaged but not a good idea to run it in that condition extensively. (Ie if a new cooler is needed and won't arrive for 4-5 days I wouldn't try to keep using the pc in its current state during that time).

So if I unscrew the radiator to give it a shake, will I need to reapply thermal paste to the CPU or am I able to put it back quickly? Just want to know for sure so nothing else gets messed up. Also, all the fans were all at full speed in BIOS, and it said that the fan speed of the one my radiator was connected to was around 6300RPM. I assume that means the pump is working, as I heard that was a common problem.

And let's say I do need a new air cooler, are there any few that are really good/good value for price? I don't really wanna spend money on anything over $100 though, figuring air coolers are cheaper. I have been looking at this one, what do you think? https://www.newegg.com/Product/Product.aspx?Item=9SIA9PV3YE9689&cm_re=cpu_cooler-_-35-608-018-_-Product

Thanks so much for the help, by the way!

EDIT: I did some more research, and someone did say that when I took out my graphics card and put it back in, it could have broke/messed something up to cause this problem. Sorry I didn't mention this, as I wasn't too sure; the problem did just start to occur right after I took out and placed my graphics card back into my mobo.
