    SubZero AIO Watercooling
    There are a number of ways to do subzero cooling.  We talk about Liquid Nitrogen quite often on the Podcast but LN2 is expensive and cannot be run for extended times.  A phase cooler is another option that can be run for a long time but is expensive and noisy.  Back in the early days of overclocking quite a few enthusiasts experimented with thermal electric cooling or TEC.  A TEC is a type of active cooling that uses electricity to move heat from one side of the cooler to another. 

    TEC cooling is how those novelty soda fridges work, how you can get heated seats in your car and for the most part they are quite safe.  Their only downside is that they require power to operate and have a wattage limit.  The basic idea is that you use the TEC to cool a CPU and then mount a waterblock to the hotside to keep the TEC cool.  If the power is run constant and the CPU load is light the processor can go below zero and if you generate more heat than the TEC can handle you can burn up your processor.

    To battle the “boost” issue with most Comet Lake CPUs Intel has created a TEC cooling controller that Cooler Master has built into their MasterLiquid ML360 Sub-Zero.  The controller will deliver just enough cooling performance to keep the CPU chilled without generating condensation while the 360mm AIO will make sure the TEC is operating correctly.

    Death of the HEDT Processor
    Rumor is there will be no LGA2066 processor “this” year.  While the article is dated the information was correct and I’m not sure 2021 will offer much either.  This is sad news considering that the HEDT platform has enjoyed being at the top of the performance charts since it was released back with LGA1366.  This platform introduced triple channel memory and a significant performance advantage over LGA775 and even LGA1156.  The next generation brought quad channel memory and a much larger socket however pressure from the Ryzen generation has pushed Intel to pack more cores into a smaller package.  This not only created more power CPUs but, also processors that rival the more expensive HEDT segment CPUs.

    While I am sad that HEDT is dead there are options available including Threadripper and LGA3647 provided that Intel decides to release more W based processors.
