This sounds like a perfect time to upgrade your fans with the aftermarket fans everyone else has been using for improved cooling and to make the system much quieter. 
[IMAGE][IMAGE]Hello I Have a Intel(R) Core(TM) i9-9900K CPU @ 3.60GHz and i was doing maintenance like cleaning the dusty out of the radiator ( water cooler ) in my computer and by mistake I broken one of blade fan from the water cooler, I'm looking for new fan replacement only. I did a lot research but I didn't find something to be compatible with the original fan spcs just plug and run.  Would there any link or model  of the top fan that I could buy that was compatible with the specifications required to not give an error ?
