I am extremely confused so I installed a noctua U9S on my I7 11700F and I followed the instructions applied enough thermal paste and tested my temps with cinebench. Day 1: 80c is my average in cinebench so far I'm happy because my case is smaller and was reaching 100c with the stock one. But day 15, 88c on cinebench. Ok this is weird so I dismounted the cooler, cleaned it properly and saw a video of good thermal paste application and boom again low temps 80c average on CB23 and after 2-3 weeks I'm here today at again 90c and I have no idea what's going on. Any ideas? The only thing I can think of is that the noctua fan is not aligned with the back fan so maybe it I raise the height of the fan a little bit but other than that I have no idea what's happening .I would appreciate some advice
