Aqua-Pcs Flow Performance CPU Block

Test Setup

Test Setup
 
For the testing phase of the review I have chosen to test the Flow Performance block against a well known water-cooling block, the XSPC X2O Delta. A Laing DDC Pro pump with OCLabs alternative top will be used to assist in making a comparison. I shall be looking specifically at pressure drop and cooling performance from within a water-cooling loop. I have included the setup details below:
 
Pressure Drop
 
* 1 x Laing DDC Pro pump with OCLabs alternative top
* 1 x XSPC X2O Delta and Flow Performance water block
* 1 x Powertech variable DC power supply (quoted accuracy +/- 0.2V)
* 1 x Multi-meter
* 25L portable water container
* 1 x IFS pressure meter. (kPa/PSI)
* 1/2" ID Clearflex tubing
* 1/2" barbs
* 2 x stop-tap fittings
 
Flow Pressure drop X2O Delta Pressure Drop
 
For the pressure drop test I used a 25L portable water container filled with 20 litres of water, with a 1/2" plastic threaded barb placed in the bottom to represent the reservoir. A stop tap was inserted immediately after the 1/2" barb to allow for a faster water-block change. The IFS pressure meter was used to record the head pressure per 1 minute testing cycle. The pump was primed and let run for a short period to ensure that no air bubbles were left in the loop. The water was allowed to run back into the container after passing through the pressure meter meter via a 'T' connector in order to minimise wasted time between water-block changes.
The first run made was with only the pump and pressure meter included in the loop and the water pressure noted. Then for second run the Flow Performance water block was included into the loop and the drop in loop pressure recorded. The same procedure will be followed for the XSPC X20 Delta water block.
 
Flow

In a similar test to the pressure drop testing above, the flow test will highlight just how much the waterblocks restrict the natural flow of a water-cooling loop. Utilising a very simple setup consisting of a pump, I/2" ID tubing, water blocks, bucket and a stopwatch we will see how far removed from the absolute flow of the pump, that the water blocks hinder flow. Running the pump into the bucket for one minute and then measuring the amount of water pumped will be the 'absolute flow' of the pump.

To calculate the flow-loss or restriction of each waterblock, they will each be included into the loop (one at a time) and the same procedure followed. The flow rate will be recorded in Litres/ hour. All simulations will be run 3 times each to ensure uniformity of the results and an average then taken.
 
 
Loop Simulation and cooling performance
 
I have decided to impliment a control setup for the testing phase of this review. In doing so I have replicated a watercooling loop similar to that in conventional water cooled setups, but also one that should return consistant and unbiased performance results. The open loop that I have chosen to run with will use be semi-restrictive in nature, but again should give quite a good indication of how the XSPC X2O and Flow Performance water-blocks would perform in your system. The water block performance will be assessed at a flow rate of 12V. For each run, the pump was allowed to run for 20 mins to ensure the evacuation of all air from within the loop. The temperatures were taken at 30 minute intervals to allow them to 'settle'. Two instances of ORTHOS will run simultaneously in order to simulate load. A backplate has also been included, so as to allow the water blocks to be tightened 'right down'.

 X20 Delta Backplate
 
Arctic Silver 5 was the TIM of choice. I have recorded temperatures at idle, load and and an overclocked loaded state; all temperatures were taken using Core Temp 0.96.1 beta and water/ambient temperatures were taken using a common household mercury thermometer. The mercury thermometer was allowed 5 minutes to aclimatise to air and water and then the temperature recorded. The setup used has been included below:
 
* 1 x Laing DDC Pro pump with OCLabs alternative top
* 1 x Flow Performance and XSPC X2O Delta water block
* 1 x Powertech variable DC power supply (quoted accuracy +/- 0.2V)
* 1 x Multi-meter
* 1 x Radiical 120.3 Radiator
* 3 x Yate Loon 120mm cooling fans
* 1/2" ID Clearflex tubing
* 1/2" barbs.
* 1 x Intel Q6600 SLACR G0 stepping quad-core processor
* 1 x ASUS P5B Deluxe wifi/App motherboard (bios version 1101)
* 1 Gigabyte 7600 GT graphics card
* Logitech generic mouse
* Logitech G15 keyboard
* 2GB OCZ PC2-6400 FlexXLC CL3 RAM
* Antec NEO EarthWatts 500W PSU
* 80 GB WD SATA II HDD

Nice review PV .

Nice to see a review of the Flow Block Finally, my logo looks good as ever.

(I created the 'Flow' Logo for Pas)
