INSTALLATION AND TESTING
After choosing the proper clip and applying the thermal paste, installation on the Socket 939 platform couldn't have been easier. Depending on your motherboard and retention bracket, you may or may not have to remove the motherboard to install the 9500. Optimum orientation of the heatsink can be achieved by using the right combination of the included hardware.
The following parameters were used throughout testing:
1) Arctic Silver 5 TIM used on all coolers.
2) Ambient temperature kept at a constant 21C.
3) Both coolers allowed to burn-in at maximum heat setting with Prime95 for two hours to partially set the thermal paste. The computer was then shut down for one hour.
4) Idle temperatures were recorded after one hour of zero load after booting to the desktop.
5) Load temperatures were recorded after two hours of maximum heat torture testing using Prime95.
6) Fan speed was set to maximum for all testing. In this case, the FanMate 2 was used to test the CNPS9500 at maximum and minimum fan speeds.
7) Idle and load temperatures were recorded at stock CPU speed (2.2 Ghz.) and at a modest 10% overclock (2.4 Ghz.). Vcore was raised by 0.1V during the overclocking runs.
The testbed we'll be using consists of the following:
- AMD Opteron 148 processor
- DFI Lanparty UT nF4 SLI-DR motherboard
- eVGA 7800GT
- GSkill F1-4400DSU2-1GBFC (512mbX 2) memory
- Thermaltake Purepower 600W PSU
- Western Digital WD2000 SATA hard drive
- Lite-On CDRW/DVD Combo drive
I've tested all the coolers in the comparison in the bare frame pictured above. This eliminates any effects that a case might introduce. Keep in mind that temps inside your case will be higher; how much higher depends on the case and airflow.
Well, the results are in and show some interesting trends. The 9500 puts up some very good numbers and, at maximum fan speed, it doesn't seem to notice the extra heat generated during overclock. At minimum speed, the fan is silent and the temperature penalty paid for this silence is very small indeed.
