Testing
The following system was used in testing:
Case: Thermaltake Armor A90
Motherboard: ASUS P7P55D-Deluxe
CPU: Intel I5 750 @ Stock 2.67GHz
Memory: 2x2GB OCZ Gold DDR3 1600MHz 2x4GB Crucial Ballistix DDR3 1600MHz
Power Supply: Antec 750W
CPU cooling:
- Thermaltake Frio
- Thermaltake Silent 1156
- Stock Intel Cooler
Using Prime95 64-bit I put the processor under stress for thirty minutes. This puts the CPU under high stress to gauge the efficiency of the Heatsinks’ cooling capabilities. Here is a comparison chart to show the differences between a higher end heatsink to a mid-range all the way to stock cooling temperatures.
| CPU Cooler | Idle (°C) | Load (°C) |
| Thermaltake Frio – 2 Fans – Med | 26C | 41C |
| Thermaltake Silent 1156 | 34C | 55C |
| Stock Intel Cooler | 37C | 62C |
I was very pleased the temperatures I received when testing all the heatsinks other than the stock Intel CPU cooler. While the higher end one is still the lowest temperature, I was surprised at the performance of the Thermaltake Silent 1156.
