CPU-Cool Z1 Coolers


Introduction
Even as far back as 1985, when electronics hobbyist Doug Dodson founded PC Power & Cooling , the company's focus has always been to power, cool and quiet computers. In this business that's a long, long time and you don't last that long unless the products you produce are first rate at an acceptable cost to the consumer. Such is the case for the PC Power & Cooling line of CPU coolers for socketed processors dubbed the Z1 line.

these are definitely not your run of the mill heatsink/fan combos but rather expertly engineered and produced cooling device which not only offer exceptional cooling properties but back them up with a full 5 year warranty from a company that isn't going to disappear in the next six months.

Electro migration can occur within your processor even within the specification set down by your CPU's manufacturer, when heat or current stresses the MOS and dielectric ions within the CPU. Current then causes electrons to transmit momentum to these ions. This results in a property known as wind force, which moves the ions in the direction of the electrons and so a gradual change in the shape of the material your processor is made of takes place resulting in permanent damage to the chip. The effect of electro migration is not immediately apparent. It can be a slow process, shortening the life span of a CPU running at a high temperature. Now don't panic, the chance of this happening is not very likely. CPUs are designed to run at temperatures as high as 180 degrees Fahrenheit, and the usual lifespan of a processor is about 8-10 years - far longer than its true usefulness. It is likely that any overclocking will shorten this significantly but, with the rapid advancements in the world of technology the likelihood that you will still even want to use this same processor is very small. Each 10C (18F) temperature rise reduces component life by 50%*. Conversely, each 10C (18F) temperature reduction increases component life by 100%. Therefore, it is recommended that computer components be kept as cool as possible (within an acceptable noise level) for maximum reliability, longevity, and return on investment.

Packaging & Setup
   PC Power & Cooling CPU-Cool coolers ship with a tube of thermal compound to help move the heat more efficiently away from you processor as well as a small instruction card that gives particulars regarding the proper mounting of the cooler.  You'll want to take a look at this card for it took me a few minutes to actually determine the proper way to mount the device.  The torsion wire mount can even get into tighter spaces than the typical clip-type mounting device so even if the area is crowded around  the CPU socket, you'll have little problem installing the Z1.
Performance
   The Z1-H moves a lot of air for its small size.  The fan's normal rotation speed is between 8200 and 8500 RPM and you should notice an approx. -10C drop in temperature over a standard heatsink on any of the AMD processors and about -7C drop on an FC-PGA Pentium III (which tend to operate cooler than their AMD counterparts.  The Z1-H is quiet too!  You will unlikely detect any variation in ambient noise over a standard retail cooler.  We measured the performance of the Z1-H on an overclocked AMD K6-III 400 (@4.5 x 112MHz - 504MHz - with 2.8V core) on EPoX EP-MVP3G2 mainboard.  The retail K6-III fan remained steady at 45.6C while running Ziff-Davis' Winstone 99 benchmark (a little higher running Quake II in demo mode for 15 minutes while the same system ran at 34.0C with the Z1-H onboard

Conclusion
  For a heatsink/fan combo for K6-2, K6-III and FC-PGA Pentium III processors, you'd have to go a long way and spend a lot more to achieve the level of cooling performance asserted by the Z1-H.  Now, understand, they're not giving these away by any means but the $21.00 price tag on the Z1-H (both Z1 and Z1-C coolers are cheaper) seems fair if you intend on overclocking and want adequate protection for your processor.  The Z1-H is easily Super7.net's Editor's Choice for all super7 CPUs.
