Intel Stock Cooler:
Intel has finally stepped up to the plate with the retail heatsink/fan combo and produced a high quality unit. It is all aluminum with a 2500 RPM fan. Can you say "quiet?" It was very effective a stock speeds and although it did not cool an overclocked CPU as well as the aftermarket units reviewed here, its performance was still respectable.
Thermaltake P4 Dragon 478 Model A1258:
This unit features a copper insert heatsink core with fins for extra cooling, a 49.4 CFM Fan @ 6000 RPM, a 3pin to 4pin adapter , a 3-speed fan speed control (high, medium, low) and thermal compound. Shipping weight is 1.5 Lbs. This is a beautiful heatsink to look at. The fan is controlled by an external slide switch which sits between the 12V connector and the fan and can be mounted on the interior or the exterior of the case. The fan has a "dummy" power plug which goes into the motherboard fan header to permit fan speed monitoring. The performance of this unit, while good, was less than expected. I believe this to be due to the mounting mechanism, which appeared to be less secure than the other fans tested. I installed this unit and ran the tests twice to be sure that I had the best installation I could get. The full power fan settings were comparable to high-end Athlon units and uncomfortably loud.
DR Thermal TI-V8639L:
This unit features a copper core in an aluminum block with aluminum fins, a 3800 RPM single speed fan which pushes 32.73 CFM, a standard motherboard fan connector, and thermal grease. The weight is 298 grams. Installation of this unit was very easy, and the unit performed very well. All components appeared to be of high quality. The only real difference between the units appeared to be in the size of the copper core which makes contact with the CPU heat spreader.
Let's move on to the test.
