Question Cpu overheating for some reason

[Fmoess]

I bought a gaming pre-built Asus from best buy 7 months ago. As soon as I read the comments I ordered a liquid cooler with it (msi 240r). I didn't have much problems with it for a long time. Sometimes it went up to 80 degrees but rarely. Couple days ago it went up to 100 degrees making noise like a freaking airplane. I shut it of. Then replaced thermal paste, took out the cooler and put it back on. Everything seems fine fans of the cooler work. Pump of the cooler works very well.Only thing was that while it was booting, a message appeared to me CPU FAN SPEED Problem. (I don't know if I plugged one of the cables of the liquid cooler wrong) Cpu still gets to 100 degress without doing anything just booting it up. I have no idea what changed over a day one day it was working fine, other day almost shut itself off.

I don’t know if this is possible but even though cooler pump works fine like 4000rpm i suspect there may be a problem with the liquid cooler.

PSU?

Make, model, wattage, age, condition (original to build, new, refurbished, used)?

History of heavy use for gaming, video editing, or even bitcoin mining?

PSU does not seem to be listed in the specs........

Noted "750W 80 plus Gold " as a response to one posted question - manufacturer = ?

Physically check to determine what PSU is actually installed. In many cases manufacturers reserve the right to make changes......

MAG CORELIQUID 240R

Been a thing for some time now, but the MAGs and MPGs have QC issues.
RMA it, since it should still be under warranty, or get something else.
