Martin, unless you can keep the coolant at a CONSTANT temperature, testing with more/less pumps skews things. I tried this, with the RD-30 at 18v and then at 24v. All I got was higher readings at 24v due to the additional heat dump... you know that pumps dump less heat the more loaded down they are (more restriction). So naturally, without a chiller to keep the coolant at a constant more restrictive blocks will have an unfair advantage right off the bat.

Yeah, maybe what I should do is just more of a simple water delta vs flow rate. I've got two running inline right now and tinkering with a different setup. Alot of it depends on the heat dump of the pump, but I've always been curious about reports of gains with stronger pumps so I want to try it and see even if as expected I get nothing in the end.

This is what I've got going now, the rad is on the rad bench so I can closely monitor air in, air out, and I've got two probes measuring the water leaving the radiator and entering the CPU block, so that should be a good number. In addition I have my flow rate meter plumbed in for the test and to make life a little easier some globe valves near the CPU block for a little less painful block switching.





Let's just say duall DDCs with tops on an extremely free flowing parts is a little overkill at 3.5GPM even with some extra restriction from the flow meter and valves...lol!


Oh, and only the highest quality Wal-mart "Great Value" distilled water at the task this time around.
