My Optiplex 790 SFF comp has the original CPU cooler as it came with with OEM I5 CPU.  Have upgraded to certified compatible I7 CPU. Apparently, both CPUs have same wattage.  My current CPU cooler has a large radiator underneath the cooling fan, and is exhausted out the back of the case, with fan atop the radiator.  Radiator connected to copper slug over CPU via 4 copper tubes.  Since I5 and I7 CPUs have same wattage, I am hoping this will be adequate.  Are there any better alternatives available?  If so, pls provide info.

Purpose of this comp is to play low- to mid-level flight sims, and internet connection for the usual stuff.  RAM currently at 16Gb (will be upgrading to 32Gb), and SSDs installed.  Zotac GTX 1650 LP Gfx card installed.  Running pretty darn well, all things considered.
