Scythe Infinity Conroe HeatPipe CPU Cooler
Published: 12th September 2006 | Source: Scythe | Price: |How we tested
For my testing I setup a system in an Antec P180b.
This comprised of:
Intel C2D E6700
Abit AB9 Pro Motherboard
Mushkin HP2 5300 RAM
Hitachi Deskstar 160gb SATA drive
Silverstone Strider 560w
OS: Windows XP Professional
The Temperature was at a pretty constant 23°C room temperature and the system temperature was 29°C.
Artic Silver 5 was applied onto both of the heatsinks to give as fair a comparison as possible. Please note that as AS5 "cures" (about 200hours and at least 2 cycles), the temps are likely to drop 1-3°C. Due to time constraints neither cooler had this luxury, and this was a fair comparison.
For the testing I had the E6700 clocked both at stock settings of 266 x 10 (2.66GHz) and 330 x 10 (3.3GHz). For the stock clocks the Abit board gives the CPU 1.3v. To get the CPU to run at 3.3GHz it needed 1.375v.
Temperatures were logged using Abit's uGuru monitoring software. Temperatures were checked with a thermal probe and found to be fairly accurate.
For idle temperatures I left the PC for 15mins then recorded the idle temperature every 10 seconds for 5 minutes, making sure I did not use any program that was not already running at windows startup.
For the load temperatures I ran an instance of prime 95 with in-place large FFT's for maximum heat and power consumption, as well as an instance of [email protected] set to take up any spare cycles of the CPU. Once again I left this for 15mins then recorded the temperatures over a 5 minute period.
For comparison I used Intels stock cooler.
