I just got some new equipment and I decided to make a test in order to see how well my new Enzotech SCW-1 (sapphire series) performs against my good old Apogee GT.
I have to mention that I don’t have any special equipment in order to measure thermal resistance or flow rate.
All the tests were software based.

Software used:
The software I used was: OCCT v. 2.0.0a, a very stressful program capable of utilizing 100% for all four cores concurrently, you can find it at:
http://www.ocbase.com/perestroika_en/index.php?Download
and Riva Tuner v2.09 with the necessary C2D plug in, you can find them here:

hardware used:
CPU: C2DQ 6600 oc @ 3.2GHz 1.3v
M/B: ASUS MAXIMUS FORMULA (bios v.1102)
MEM: OCZ OCZ2RPR800C44GK DDR2 4GB PC2-6400 REAPER CL4 EDITION @ 4-4-4-15 2.0v
VGA: ASUS 8800 GTX 768MB HTDP
HDDS: SEAGATE ST3250410AS 250GB SATA2, SAMSUNG HD502IJ 500GB SATA2, SEAGATE BARRACUDA 7200.11 ST3750330AS 750GB SATA2
DVD-RW: NEC AD-7173S
SOUNDCARD: CREATIVE SOUND BLASTER FATALITY
PSU: PC POWER & COOLING inc, 750W Silencer Black
CASE: LIAN LI PC-V1200B
MONITOR: EIZO Flexscan S1911
Watercooling parts:
WBs: Enzotech SCW-1, Swiftech Apogee GT
Pump: Swiftech MCP655™ series 12 VDC Pump
Radiator: Alphacool NexXxoS Pro II - Rev. 2
Reservoir: Swiftech MCRES-MICRO
Tubing: PrimoFlex Tubing 1/2 ID x 3/4 OD – Clear
Rad fans: Silenx Case Fan 120mm Pro.
The procedure:
In both scenarios I left for a few minutes the processor idling in order for the temps for all four cores to stabilize and then OCCT started running for the default one hour test. Room temp was stable at 25 °C in both tests (you see now In Greece temps are going high).

Apogee GT
At idle we see that with the Apogee GT the four cores had the following temps:
http://i286.photobucket.com/albums/ll104/mpamphs70/Apogeeidle.jpg
CPU0=34 °C, CPU1=36 °C, CPU2=32 °C, CPU3= 34 °C
While at full load with OCCT the temps had the following values:
http://i286.photobucket.com/albums/ll104/mpamphs70/Apogeefullload.jpg
CPU0=55 °C, CPU1=55 °C, CPU2=51 °C, CPU3= 54 °C.
In the end of the test we got the following charts for all four cores.

Enzotech SCW-1
At idle we had the following temps:
http://i286.photobucket.com/albums/ll104/mpamphs70/Enzotechidle.jpg
CPU0=32 °C, CPU1=35 °C, CPU2=30 °C, CPU3= 32 °C.
While at full load we had the following temps:
http://i286.photobucket.com/albums/ll104/mpamphs70/Enzotechfullload.jpg
CPU0=52 °C, CPU1=52 °C, CPU2=48 °C, CPU3= 49 °C.
In the end of the test we got the following charts for all four cores.

http://i286.photobucket.com/albums/ll104/mpamphs70/2008-05-29-18h25-CPU4.png
So with the Apogee GT we got the following DT values:
http://i286.photobucket.com/albums/ll104/mpamphs70/Apogeeidle-max.jpg
while with the Enzotech SCW-1 we had the following values:
http://i286.photobucket.com/albums/ll104/mpamphs70/Enzotechidle-max.jpg
We clearly see now that the DT values with the Enzotech waterblock are better than with the Apogee one, mentioning also that we have lower temps (idle, max) with the Enzotech waterblock in all four cores
Comparing each core
The next step was to compare each core independently with the two waterblocks. So we got different core temps across the one hour OCCT test.
For the first core ( CPU1) we have the following graph:
http://i286.photobucket.com/albums/ll104/mpamphs70/CPU1.jpg
We notice that the Enzotech SCW-1 waterblock outperforms the Apogee GT in the one hour OCCT test. With the Apogee GT we got a max temp of 55 °C at the 53rd minute of the test while with the Enzotech a max temp of 51 °C at the 48th minute of the test.
For the second core (CPU2) we have the following graph:
http://i286.photobucket.com/albums/ll104/mpamphs70/CPU2.jpg
Again the Enzotech SCW-1 outperforms the Apogee GT in the one hour OCCT test. With the Apogee GT we got a max temp of 55 °C at the 53rd minute of the test while with the Enzotech a max temp of 52 °C at the 48th minute of the test.
For the third core (CPU3) we have the following graph:
http://i286.photobucket.com/albums/ll104/mpamphs70/CPU3.jpg
The same results here for the Enzotech waterblock which outperformed the Apogee one. With the Apogee GT we got a max temp of 51 °C at the 53rd minute of the test while with the Enzotech a max temp of 48 °C at the 48th minute of the test.
And finally we had the last core of the test (CPU4).
http://i286.photobucket.com/albums/ll104/mpamphs70/CPU4.jpg
The Enzotech again leads the way. With the Apogee GT we got a max temp of 54 °C at the 53rd minute of the test while with the Enzotech a max temp of 49 °C at the 48th minute of the test.
Summarizing
It’s clear from the above tests that the Eznotech SCW-1 outperformed the Swiftech Apogee GT in every separate core test. I’m much happier now with my new waterblock.
Also take note that with Rina Tuner the cores referred as CPU0, CPU1, CPU2, CPU3, while with OCCT the cores referred as CPU1, CPU2, CPU3, CPU4. There was also a difference in the max temp of CPU0 where Riva Tuner reported a temp of 52 °C while with OCCT max temp was 51 °C, so in the graph I used what OCCT reported.
All the tests I did were software based so if anyone has any better information I’ll be glad to know.
I have to mention that I don’t have any special equipment in order to measure thermal resistance or flow rate.

So with the Apogee GT we got the following DT values:

while with the Enzotech SCW-1 we had the following values:
