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...

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.

Sorry, but As FarAs I Know, it isn't possible to do the kind of swap you're talking about.

It is made even more difficult by the fact that the controlling ...

I would second the earlier comments, you can do quite well by making your own from an existing sensor, all you need is some appropriate silicone or other sealant and a bit of shrink tube for the sensor tip, and epoxy to seal up the hole you use to stick it into the plumbing.

ATX is here now, and fits todays products. BTX is vapor, and may or may not fit future Intel products (AMD at present is saying no to BTX) I don't think ATX is going away anytime soon, so I would stick with ATX until and unless I see a really good reason to purchase BTX.
