SSD running slow with new sata ribbon Mac mini mid-2010 on Catalina

Hello everyone! I’m new to the community and I am trying to remedy my issue. I just purchased a Mac Mini mid 2010 for $15 that was expected to have a bad hdd but turned out it was the sata cable. I ordered a 1tb SSD Hynix gold and 16gb of ram. I updated my Mac from snow leopard that it came with to high sierra then cloned that to the SSD. After installing the SSD and ram I broke the temp sensor for the drive so the fan is running at full rpm. Not a big issue but thought I should include every detail, after installing the sata to the SSD performance wasn’t noticeable on boot and load times but it was when loading content that was almost like a flash so I didn’t really think about it. Now I kinda took a bold leap and installed Catalina and as expected some performance issues where faced but it’s very minimal. I feel as if my Mac should still be able to load things with ease regardless of cpu consumption which stays at a steady 40% used. Please bare in mind that I haven’t owned a Mac computer since the 90’s Macintosh so I had to learn everything in a week time span. Regardless my write speeds are 115.6MB/s and read is 138.7MB/s after multiple benchmark tests that was the average. At this point I am lost and can’t find a straight answer is. Oh I also purchased software for TRIM and it didn’t affect the speed of the SSD. Thank you in advance for taking the time with my issue!

I am now typing from my Mac mini still running Catalina just wanted to update that the lag is gone after letting it go in sleep mode over night but that hasn't changed the load speeds for the ssd still slow for what it is. the cpu usage has dropped significantly since yesterday and is now resting at 4% not 60% and it runs like butter. if anyone has any pointers on how to speed write and read speeds that would be awesome.
