After careful consideration I have decided to transfer all hardware review activities to a new domain. I purchased Hardwareasylum.com in 2012 and have been working hard to build a new and improved Ninjalane on that domain. If you are reading this you have reached one of the archived articles, news, projects and/or reviews that were left behind during the site migration.

Demonic XTC Waterblock (P4) Review
Author: Dennis Garcia
Published: Tuesday, March 16, 2004
Benchmarks
The Demonic Watercooling XTC can be used on AlthonXP and Pentium 4 systems at any speed with performance and overclocking in mind. Here is an overview of the system and testing methodology.
The system as it was tested
Abit IS7-G
Intel Pentium 4 3.0C 800Mhz FSB (SL6WK)
Demonic XTC
D-Tek White Water
Danger Den RBX
The watercooling system consisted of a Hydor L30 pump, Black Ice Pro radiator, Sunon 120mm fan (running 7v), and a small reservoir for water storage and air collection. 3/8" I.D. hose was used with adaptors used to connect with the waterblock.
Motherboard Monitor was used to obtain and record system temperature information and a game of Halo provided the 100% processor usage.

Editors note: Even though the Windows XP task manager reported 100% processor usage we could never attain a 100% of the rated heat output as documented by Intel (see below)
when using Halo as a basis for that heat production. Knowing this the game was played until the maximum temperature was attainted and stabilized, or when the round was over.
Other things to consider when judging software induced heat output.
a) Clock throttling by the processor at high temperatures.
b) Normal software isn't designed to produce maximum heat output.
c) Variances of cooling temperature.
d) Variances in CPU load.
e) Inaccuracies in thermal diode readouts.
Of course the list goes on..
My testing methodology is aimed to provide a real world look into this waterblock given the test system provided.

Default Processor Speed and Vo
Allowed variance for this test = 90%
CPU Watts = 81.9W
0.31 C/W = (48C - 25C)/(.9(81.9W))
CPU Watts = 81.9W
0.31 C/W = (48C - 25C)/(.9(81.9W))
Overclocked Processor Speed
For this next test we cranked the FSB up to 235Mhz and re-ran the tests.
ocMhz = 3525
ocVcore = 1.65
Allowed variance for this test = 90%
CPU Watts = 108.7W
0.27C/W = (51C - 25C)/(.9(108.7W))
ocVcore = 1.65
Allowed variance for this test = 90%
CPU Watts = 108.7W
0.27C/W = (51C - 25C)/(.9(108.7W))
Benchmark Conclusion
With the addition of the acceleration jet the Demonic XTC is now on par with the D-Tek White Water block and a close second behind the Danger Den RBX.
