I wouldn't think it is that funny to Vic at the moment, but he does like regaling us with personal medical details that we really don't want to know about. 50/50 here I think.

Moving swiftly on ......

I often wonder how much a pallet costs to make, can't be much as they are obviously classed as expendable having regard to the value of the goods on them. Must be the same as those cement, sand, and ballast canvas bags that get dumped or not taken back.


Not every shipper considers them "expendable." Some want them back or you pay extra.

Where i used to work they saved the pallets and got money for the " emptys" same as metal swarf used to take that to sackers and get money for it .
There's 2 " main types" of pallets , there's some "weird sized" ones " but there are "euro" pallets built to ISO specs ( am being serious think there's 2 sizes of pallet ) the dimensions of them are so they fit into 20 / 40 ft containers for shipping maximising the space avalable inside the thing . more goods in a container more money earned etc

I hear there are 5 different sizes of pallets.
My work place uses the heat treated pallets. So no pests insects are spread across the globe. The boss charges $7.00 usd a pallet. Then whatever's on top of it gets added to the invoice.

You're most probably right ain't going to "serch & look it up on google ;-) "
know you got different sises but most things were on large or small " Euro" pallets , engineering , we didn't have that much to do with them , but i've repaired ( welded up ) 20 / 40 ft containers for a job years ago now and remember there were mainly just 2 sises of pallet they unloaded before the sparks could fly ;-) .

Do know you don't see many "euro's" on a bonfires here come 5th of November but always loads and loads of the other pallets . Can't blame your boss for charging for em , gota make your money somehow , that's the same whatever country you're in ;-) .

I'm not ready to bite that bullet either yet. Still leary of leaks. I use a Noctua NH‑L12 cooler on my system.
I'm posting this on my iPad.

I did not spend any money on computer bits, the untested cooler has been laying in My kitchen cupboard, as to why I went water cooling, it was ease of maintenance when it comes to dusting.

I know some don't like that, it's My descision.

I have to remove 8-12 screws, both are similar, but electrical is a bit different from each other, also water pulls more heat out, when crunching the cpu runs at 3.81GHz, stock cpu speed is 3.60GHz. And cooling fans don't have to be insanely fast.

Eric experimented with water cooling his computer system once. Given the number of algae strains he managed to grow in our garage, I was sad that I didn't know more about botany.

The following picture best expresses my opinion on water cooling:

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.

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.

Most folks.......or maybe not as many as I may suppose, would know that simple convection could not possible draw enough fluid through the hoses to make a dent.

I love engineering.....all part of the fun.
Fans in or fans out? LOL.
All sides off in my case. Or cases, as it may be.

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.

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

So, are you trying to tell me that sometimes slower coolant flow is actually better than running it through as fast as possible? I have a reason for asking.

---

"Freedom is just Chaos, with better lighting." Alan Dean Foster

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.

Yes, you want it to be in the cold side long enough to absorb the heat, but not so long that there is a big swing from one side of the chip to the other. You want it in the hot radiator long enough to cool it all the way down to room or if you have a chiller lower. If you are a real engineering type you might have different tubing size in those parts to help get the coolant flow properly balanced. In any case if you run the coolant too fast, the coolant won't get fully cold out of the hot radiator so when it tries to cool the chip it has less capacity to soak up the heat.

It is almost the same thing as a air conditioner loop, but there the coolant undergoes a phase change and there is usually a pressure regulator in the loop to meter the flow and help prevent an ice up. However if the system is either under or overcharged the regulator loses the ability to keep things in balance and too much or not enough coolant flows in the loop.

My problem is I'm running 4 cpu's and I wanted to cut back at night to maybe 2 so I programed it in but SETI doesn't seem to do it. I think I got it right but maybe someone can give me some ideas to make it work?
