Dissipatori Socket A - Socket 370

Both the Celeron II and the FCPGA Coppermine CPUs are extremely popular among overclockers - reason enough to take a close look at cooling solutions for these CPUs. We tested a total of eleven heatsink/fan combos for Socket CPUs. All of these coolers will fit Intel PPGA Celeron, K6-X, and Thunderbird/Duron CPUs, while nine of them are also suitable for FCPGA (Coppermine and Celeron III) CPUs. At first, our intention was to include only FCPGA-compatible coolers in this comparison, but the overwhelming popularity of Global WIN's FDP32 and FEP32 heatsinks has led us to include these two FCPGA-incompatible models in the comparison.

All tests were done with a PPGA Celeron-533 CPU. This CPU was chosen because it is the most power-hungry Celeron CPU ever produced; it emits much more heat than the newer FCPGA CPUs, and therefore is more suitable for accurate performance measurements. The temperature readings were obtained with the CPU's internal diode. The motherboard used was an ASUS P3B-F. All heatsinks were tested with high quality thermal compound. If a thermal pad was present on the heatsink, it was removed. To show how greatly thermal compound improves performance, we have additionally tested the boxed Intel heatsink with its preinstalled thermal pad.
