I first began testing to make sure all of the features worked as they should. As I stated before there were some problems, while trying to use some of the buttons. Mainly, some of the buttons didn't work. The next feature I decided to test was the alarm. I set the alarm speed for the GPU to 40C. Because both the GPU cores were at 44C the alarm went off. I then decided to set the alarm to 50C for everything. After I had done that I turned off all of the fans. Only the GPU's went above 50C and the alarm again sounded. I then decided to set the alarm for the CPU and Memory heat spreader to 30C just to make sure they work. Sure enough they did.
The next feature I wanted to test was that the Sentry 2 will warn you of a defective fan. While the system was running I randomly unplugged a fan. For the first 5 seconds I thought nothing would happen. About 5 seconds later the alarm went off. The cool thing was the alarm was way different from that of the temperature warning alarm. This would help you differentiate between the two. Another nifty feature is that you don't have to worry about finding this troublesome fan. When a fan is defective, or in my case unplugged, the number for which fan it was will begin to blink. This should help you easily diagnose and replace the troublesome fan.
In order to test how well the sensors work, I wanted to use a thermometer and compare its readings to those of the Sentry 2. However, I had no thermometers that read in Celsius, so this just wouldn't work. Instead I decided to use the onboard sensors in each device for comparison. I used the CCC in order to record GPU temps; Core Temp to record CPU temps; and HWMonitor to get my chipset temperature. The sensors are pretty close to where they should be, so we should get similar temperatures. At least I hope so.
- Processor: Intel Core i7 920 (3GHz)
- Motherboard: MSI X58 Platinum
- Memory: Mushkin HP3 12800 7-7-7-20
- Video Card(s): Sapphire HD 4870 X2
- Power Supply: Zephyr 750W
- Hard Drive: 1x Seagate Barracuda 750GB
- OS: Windows Vista Ultimate Edition SP1 64-bit
Aside from the CPU temperature, the Sentry 2 was extremely close to the onboard sensors. This is good, because rather than running multiple monitoring programs, you can just take a look at the touch screen on your case. The reason the CPU temperature is so different, is because I placed the sensor on the HSF. The on-die sensor is actually in the CPU, which if you could install the sensor into the CPU, you would get a temperature closer to that of the software reading.
