AFAIK, SCUBA tanks are all either steel or aluminum, not copper. I suspect you might have trouble finding anything that size in copper. Note that a plain copper tank also wouldn't be that great for cooling, probably not significantly better than the same size steel or Al tank. The critical thing for...

The big question is what sort of flow resistance your radiator offers, but I would be VERY surprised if it had significantly more than the commonly used heater cores. A hot water heating radiator is intended to flow fairly high volumes when used normally, which means it can't be that resistive. Thus...

*IGNORE* flow volume figures!!! They are not that important, as you will NEVER get that sort of flow. What you need to look at is the MAXIMUM HEAD PRESSURE, usually expressed (for our pumps) in inches or meters of water pressure. This defines how the pump does when confronted with restrictions such ...

No you should not stick an exposed wire thermocouple in coolant (of any sort). It probably wouldn't blow anything up, but the resistance of the coolant would probably screw up the readings in addition to potential corrosion issues. Remember that a thermocouple is made from different kinds of metal b...

I've never cared about the color of my coolant, but I've seen reports that some antifreeze is UV active, color depending on brand.

Beware of two 'gotchas' though... 1. If the controller uses PWM, you will get unpredictable and probably innaccurate results as the PWM frequency will make the RPM frequency signal erratic. 2. The RPM monitoring circuit works by referencing the fan ground wire which MUST be connected to ground. Some...

For a CPU, the best place IS between the HS and the chip carrier. NOT between the die and the HS, but next to the die in the gap between the carrier and the HS. Otherwise the best bet is to figure out where the airflow hits the various parts you want to monitor, and put the sensors on the side AWAY ...

The Digidoc is made by a company (Asian I believe) with the rather confusing name of "MacPower". AFAIK they have no connection to Innovatek.

examine the thermistor lead carefully - see if it's not actually two wires in a single cable? If so, I've heard some folks have had luck cutting off the end and shorting the wires together. Alternatively, try heating the end of the thermistor cable w/ a match or other high temp source, see if that m...

Check w/ McMasters on the splitter, I think they may have them. Otherwise I would run 1/2" from the res to the inlet of the 1st pump, possibly between the pumps, but 3/8" on the outlet from the 2nd pump on. For sealing off the fan, I'd just use a peice of cardboard and some tape first, then if it wo...

Sorry, but As FarAs I Know, it isn't possible to do the kind of swap you're talking about. The fan innards are very tightly tied to the boards and are pretty much of a matched set with the fan hubs, so swapping would be a real problem. It is made even more difficult by the fact that the controlling ...

Nice job, however I would be concerned about trapping air in those big upright sections. Long as it works though, that's the big thing.

A couple of comments: 1. Re the pump only tests - You probably read close to ambient on those tests becase w/o the mobo heat you weren't maxxing out the rad, so it was able to get rid of all the heat that the pumps were putting out. (FWIW, my guess is that the pumps were basically adding their rated...

Putting the res at the top is not a complete cure for air trap problems. If you have enough of a high spot in your loop it can trap air, no matter where in the loop it is. Rads are particularly bad about this, but I've also heard of problems with some block setups. OTOH, the res will catch bubbles n...

Could be... You are adding some level of extra heat from the 2nd pump, I forget the Watt spec for these, but I would lay odds that by the pump design nearly all of it's rated power will end up in the coolant. (minimal air dissipation and motor closely coupled to the Al pump block) Your rad has to ge...
