XSPC X2O Delta CPU waterblock

Test Setup

Test Setup

For the testing phase of the review I have chosen to test the XSPC against a well known water-cooling block, the D-Tek FuZion. 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 D-TEK FuZion waterblock
* 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

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 XSPC X2O Delta waterblock was included into the loop and the drop in loop pressure recorded. The same procedure will be followed for the D-TEK FuZion water-block.

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 water-block would perform in your system. The XSPC X2O performance will be assessed at flow rates at 9/10/11/12 and 13.2V respectively. 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.

Arctic Silver 5 TIM was used instead of using the syringe supplied in the XSPC X2O Delta packaging. I have recorded temperatures at idle, load and and an overclocked loaded state; all temperatures were taken using Core Temp 0.95.4 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 XSPC X2O Delta and D-TEK FuZion water-block
* 1 x Powertech variable DC power supply (quoted accuracy +/- 0.2V)
* 1 x Multi-meter * 1 x Tribal Overkill reservoir
* 1 x Toyota Camry heater core
* 2 x Scythe Minebea 120mm cooling fans
* 1/2" ID Clearflex tubing
* 1 x Swiftech MCW60 GPU block
* 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 Palit 8600 GT graphics card
* Logitech generic mouse
* Logitech G15 keyboard
* 2GB OCZ PC2-6400 Titanium RAM
* Antec NEO EarthWatts 500W PSU
* 250 GB Seagate SATA II HDD

Intel Q6600

I have also included temperatures from Intel' stock heatsink as a comparison

Excellent review there PV,

I've been waiting nervously for this cos I'd already plumped for the FuZion

I'm now very happy I did with my hotter running B3Quote

Thanks Uncle_Fluffy for the feedback. The X2O Delta is still a very nice block and more than capable of cooling your quad-core. But you'll enjoy your D-TEK too Quote

Nice review as ever Pvs.Quote

nice review Matt, i would not be surprised if this block would out preform the fusion when the 8 and 16 cores come out. kind of like the storm and fusion today.Quote

Hi ai_01 and Ham...thanks for the feedback. Your comment certainly holds some weight as XSPC are working on a new revision of the Delta as we speak. As I find out more details I'll let you know...Quote
