Pro/Forums - View Single Post - Steady State or Open Testing for Waterblocks

With all the hoopla in the forums lately I wanted to post a question for us all to consider.

Why doesn't anyone test waterblocks witha rig that cycles water through the block only once? This would allow us to see the effects on the blocks ability to remove heat from the core ONLY.

1. Such a setup would have a large holding tank, or would use a constantly repenished source of water at a constant temperature.

1A. The large holding tank has some issues with affecting flow rate.

1A1. The pressure at the pick up point in the tank will change as the water level in the tank is depleted.

1A2. Hard to insulate against effects of room tempurature.

1B. A constantly replenished source of water at a constant temperature can be had by locating the test rig near the spigot closest to the incoming water line for the testing facility.

1C. Water table temps in any particular area will remain constant at any testing area.

1D. Incoming water temps can be affected by testing area constraints.

1D1. Cycling well pumps.

1D2. Long interior piping runs to the test area.

1D3. Storage capacity of the well presurization tank.

1D4. Insulation of the incoming lines. piping, and holding tanks.

1E. Water temps can be stabilized prior to testing.

1E1. Run water through the spigot at a higher flow rate than the testing will occur at.

1E2. Allow the test rig to run with CPU heating software for a period prior to actual testing.

2. Tests should be recorded at different flow rates that encompass a range normally found in typical systems.
