The fan controller allows the power to be turned up and down like a radio knob. I will test absolute high and absolute low. The test for both speeds will have the temps recorded Motherboard Monitor 5 using the highest values reached at either idle or load. The idle test will consist of 5 hours of the computer sitting and no programs being opened. The load will consist of 2 hours of non stop Halo gaming.</p> <p>The test setup is as follows. Abit IC7, P4 2.6C, 1024 PC3200 RAM, ATI 9700 pro. The case will be closed and the system fans will consist of 3 SmartFan 2’s. One might wonder why I mention the video card, RAM, and system fans. I like you to have a complete idea of what will be in use generating heat inside the case and what will be used to dissipate the heat.</p> <p><strong>Results:</strong></p> <p align="center"><img src="atruereview/zalman7000/Graph.gif" border="0" width="304" height="383" alt="Zalman CNPS7000A-Cu CPU Cooler"></p> <table width="468" border="1" align="center" cellpadding="0" cellspacing="0"> <tr> <td width="185"> </td> <td width="128"> <div align="center"><b>Idle</b></div> </td> <td width="147"> <div align="center"><b>Full Load</b></div> </td> </tr> <tr> <td height="20">Zalman High (2.6 GHz)</td> <td height="20">40.0°C (104.0°F)</td> <td height="20">53.0°C (127.4°F)</td> </tr> <tr> <td height="20">Zalman Low (2.6 GHz)</td> <td height="20">42.0°C (107.6°F)</td> <td height="20">56.0°C (132.8°F)</td> </tr> <tr> <td>Evercool (2.6 GHz)<br> </td> <td height="20">45.0°C (113.0°F)</td> <td height="20">55.0°C (131.0°F)</td> </tr> <tr> <td width="185" height="20">Room</td> <td width="128" height="20">25.5°C (78.0°F)</td> <td width="147" height="20">26.0°C (79.0°F)</td> </tr> </table> <p>Idle at the lowest fan speed saw a max temperature of 42C and the max under load was 56C with a room temperature of 78F. Idle at the highest fan speed saw a max temperature of 40C and the max under load was 53C with a room temperature of 79F. A Pentium 4 has a thermal diode inside the processor so temperatures are very accurate. </p> <p>Compare temperatures to the last cooler I reviewed, <a href="atruereview/zalman7000/../evercool/index.php">Evercool CUW8-715</a>, the Zalman outperforms it by quite a bit on the high setting and the low setting with a very low CPU load. On either setting the Zalman is tough to hear and a lot quieter than the Evercool.</p> <p><strong>Conclusion:</strong><br> The temps were really good, especially given that by using the loudest setting with the side panel on, the cooler was still silent. The Zalman CNPS-7000A-Cu is a great cooler with ability to cool exceptionally well under situations where noise is a huge factor and performance is required to allow for overclocking, extreme gaming, or other high heat situations.</p> <p><strong>Pros:</strong></p> <ul> <li> Quiet</li> <li>Great performance</li> <li>Easy to install</li> </ul> <p><strong>Cons:</strong></p> <ul> <li> Heavy</li> <li>Large, won't support all motherboards</li> </ul> <p><br> <strong>Rating:</strong></p> <table width="227" border="0"> <tr> <td width="105">Overall:</td> <td width="183">Very Good</td> </tr> <tr> <td>Installation: </td> <td>Very Good</td> </tr> <tr> <td>Price: </td> <td>Fair</td> </tr> <tr> <td>Packaging:</td> <td>Very Good</td> </tr> <tr> <td>Compatibility: </td> <td>Fair</td> </tr> </table> <p><strong></strong>(Ratings Possible Terrible, Very Bad, Bad, Fair, Good, Very Good, Excellent)</p> <table width="75%" border="1" align="center"> <tr bgcolor="#0066FF"> <td><div align="center"><strong><font color="#FFFFFF">More Information</font></strong></div> </td> </tr> <tr> <td><div align="center"><a href="http://www.atruereview.com/forum/viewtopic.php?p=556">Discuss in our forums</a></div> <div align="center"></div> </td> </tr> </table> <p> </p> <p align="left"><a href="atruereview/zalman7000/index.php"></a> <a href="zalman7000/index.php">Previous (Introduction & Features)</a></p> </div> </td> </tr> </table> </div> <div id="footer" class="clr"> <div class="rk-1"> <div class="rk-2"> <div id="the-footer"> <script type="text/javascript"> var gaJsHost = (("https:" == document.location.protocol) ?
