I am enjoying some Budweisers, and a 8 swallow swig of 100 proof legal moonshine while cooking pork chops, green beans, and bread sticks.
My wife is having a baked potato in addition to the above, except no alcohol.

It could be worse.....

That sounds excellent! It's hard to imagine so much mass could make up one object.
I can't wait to see the results in 2018.

Yes. Running it slower keeps it in the radiators longer, but it quickly exits the GPU's. With the chiller CPU loop, the added electricity and size of the chiller tips the balance.
I started with a much stronger pump, and learned that too much power, just added heat. Slow down the coolant flow, but don't stop it. Don't let the heat from the pump add to the coolant temperature.

The trick, is to make the coolant stay in the cooling region as long as possible, but keep it in the heating region as short as possible. That way more heat is dispersed than collected. It's all physics.

Steve

Of course equilibrium is reached. The greater the cooling surface, the lower the resultant temperature.

Do you use the pump to move the water or just gravity heat?

I use two separate 10 watt pumps. One for each loop. Any greater than 10 watts, generates heat for the loop.
The fans are set to pull air through the radiator. Pushing air adds the fan heat. It's all engineering.

When properly designed and implemented, water cooling is unstoppable.
I have been using it for years, without leaks. My system is made up of two separate cooling loops.
One is for both GPU's, and consists of 2, four 140 mm fan radiators. Each GPU loop is cooled with a radiator just before it hits the GPU.

The second is the CPU cooler, which runs through a 1/2 hp aquarium chiller. My current fluid temp is set for 50°F, which means with a 4.4 GHz clock speed, my CPU temps are only 49°C. My GPU's, massively overclocked, never get above 60°C. Right now, they are less than 55°C. I am ramping up for the latest challenge.

These are old GPU's, but at some point I will modernize them, but will keep the same cooling system.
Because of the fans and chiller, this is not a silent system, but it is impervious to overheating.

With a huge storm coming tomorrow, a huge amount of beer just makes sense. I have the day off.

Blizzard tomorrow with up to 20 inches of snow and high winds.
Currently 13.6°F and sunny.

Fake.
Some of the episodes are so far fetched, it is unbelievable how they came up with that nonsense.
If it ever existed in the tabloids, then they make an episode out of it.

Now I am wondering if there are space dinosaurs.
I would say that is just as likely as other forms of life.
That would really be something to see, but of course they would most likely not resemble earth dinosaurs.

Walking while looking at the phone is also a problem in my work place. People stair at their phones as they walk the corridors. They move slowly, and meander left and right oblivious to everything around them. It is difficult to get around them. My wife's ex-husband was killed by a texting driver. I do wish people would do what I do. Walk/drive to your intended location, then pull out the phone. I know that is against human nature, but no matter what my phone does, I will not touch it until I am in a stable location. Ever.

That is at the heart of my concerns. I know things can be very difficult for many in the US, but no where nearly as difficult as they would be with a major military /nuclear confrontation. I prefer the problems we have now, to those created by such a huge crisis.

I agree completely. I certainly don't have solid answers. I know what we have been doing has not done much to deter the regime, or help the North Korean people. I am searching for a solution that does not involve a catastrophic war for many nations.

Really my point was what would happen to North Korea if the world began to open up, and establish trade and communication. The government would have no reason to exist. It is the pretense of war that gives them that reason. It may be that North Korea will keep bringing the situation close to war, without crossing the line. They want to stay in power, and war would certainly be their demise.

It's also no longer the case in Cuba.
Things have started to change.
It won't happen overnight, but I do see the lives of Cuban citizens improving over the next few years.

I think Cuba will discover its own model. One thing that differentiates it from North Korea and Iran is that it is not, nor wants to be a threat to anyone.
