Looking for High Capacity CPU Cooler

     I’m looking to build a new machine, primary function will be a faster more robust web server.  Because Google, Duckduckgo, Bing, and now even SwissCows has gotten heavily into censoring information about adverse vax events, certain political issues, etc, I want to put a yacy search engine back up, but when I had one before it really loaded the server too heavily, in particular it’s memory requirements were excessive.

     So I’m looking at building a machine based around an i9-10940x, the reason for this particular CPU is that it is an Intel core CPU which can address 256 GB of RAM, has 14 cores, 28 threads, and can be overclocked to 5Ghz.  But overclocking it at that speed can make it dissipate more than 400 watts, so I need a very robust cooler.  The coolers I’ve been using, EVO-212A max out at around 240 watts.  I don’t like the Xeon CPUs because first they are excessively expensive, and second have slow memory controllers.  I’ve had bad luck with reliability with AMD in the past so I stay clear of that.  No offense to anyone who is an AMD or Xeon fan, just stating my reasons for going with this particular CPU.

     The challenge, when I’ve looked for coolers in the past, sites used to have TDP ratings, these seem to be mostly absent from Noctua, CoolerMaster, and other brand sites now so I don’t know how to identify a suitable cooler.  Any help with this would be appreciated.

     Another thing I am looking for is an alternative to opendmarc.  It seems to fail sometimes when the From: line is extremely long, but I’m not having any success finding an alternative.  If anyone knows of something that will work under Linux please let me know.
