So I was annoyed that my PC fans were so loud and decided to enter the BIOS and change fan speeds. I put them all on smart fan mode and changed the curve to where I like and i worked for a little bit but while I was watching YouTube i decided to check what my CPU temper were and i noticed they were rapidly changing from about 34c to 45c and everything in between. Im not familiar with how the closed loop cooler work when it comes to fan speed on the radiator so I'm not sure where I went wrong.
CPU temps rapidly changing with closed loop cooler.

By closed loop cooler i assume you are referring to an AIO water-cooler correct? Water coolers while generally having a higher capacity to dissipate thermal energy are not as responsive as an air cooler. in an air cooler all you need to do is speed up the fan whereas a water cooler needs to speed up the fans and increase the pump speed. since there is moving liquid there is always slight delay between a temperature spike and the cooler catching up. what im guessing is that your fan curve is letting the cpu slowly increase in temp and then the pump panics and flushes the heat very quickly lowering it again.
first of all make sure your pump is plugged into the cpu fan header on your motherboard if your board does not have a dedicated pump header which some high end boards do. this will ensure the pump is linked directly to what the cpu is requesting in terms of cooling. then if you have a second cpu fan header plug your radiator fans into it via splitter if needed as this will improve responsiveness as well. Mother than that i would tweak your fan curve until you can keep it steady enough but the temps you are looking at are still plenty cool so i wouldn't worry too much overall.
