Fan, Cup and Copper Pipes: Zalman CNPS8700 LED and Thermaltake V1 Processor Coolers (page 9)Category: Coolers [ 08/30/2007 | 12:09 PM ] Real-time Pricing and Availability: Thermaltake Enthusiast (CL-P0401) Cooling Fan Products
Specifications and PricingThe following table lists the specs and recommended prices of the tested coolers:
Testbed and MethodsThe coolers were tested on an open testbed and in a system case with the following configuration:
I’ll explain in the Results section why I had to use a dual-core CPU instead of the traditional quad-core model. All tests are performed in Windows XP Professional Edition Service Pack 2. SpeedFan 4.32 is used to monitor the temperature of the CPU, reading it from the CPU sensor. The CPU is heated up by means of OverClock Checking Tool version 1.1.0 in a 24-minute test during which the system remains idle in the first and last 4 minutes. The mainboard’s automatic fan speed management is disabled for the time of the tests. The thermal throttling of the Intel Core 2 Duo processor is controlled with RightMark CPU Clock Utility version 2.25. Our CPU begins to skip clock cycles on reaching a temperature of 82°C and higher. I perform at least two cycles of tests and wait for 20-25 minutes for the temperature to stabilize during each test cycle. The maximum temperature of the hottest CPU core in the two test cycles is considered as the final result (if the difference is not bigger than 1°C – otherwise the test is performed once again). Despite the stabilization period, the result of the second cycle is usually 0.5-1°C higher. The ambient temperature was monitored by means of an electric thermometer and remained at 28.5°C during the tests. The fan rotation speed is shown in the diagram as reported by monitoring tools. I took two opponents to the tested coolers: Zalman CNPS9700 LED and Thermalright Ultra-120 Extreme. The Zalman CNPS8700 LED is about $20 cheaper than the CNPS9700 LED and is positioned differently on the market. So I guess it’s interesting to know how weaker the more compact and cheaper cooler is in comparison with Zalman’s top model. The Thermalright Ultra-120 Extreme is currently one of the best air coolers if not the very best one. So it makes a good point of reference. I tested the cooler from Thermalright with two very quiet 1100rpm Scythe Minebea fans installed for intake and exhaust. <%BANNER[banner_468x30]%>
