Overclockin.com heeft een behoorlijk heftige heatsink roundup gepost waarin 9 PIII en socket7/370 koelblokjes op de testbank worden gepijnigd. Algemeen winnaar van de comparison is de welbekende Alpha P125:
The Alpha P125S heatsink (available from 3DfxCool for $50) is one of those things that just amazes you the first time you take a look at it. It is, in a word, huge!! The Alpha P125S kit (yes, you will have to assemble it, but you can do it. Very straightforward.) comes with the heatsink itself, a cover that is used to direct the airflow, two fans rated at 27.2 CFM each, various screws, spacers, a backplate, and a tube of thermal grease. I'm not going to cover the assembly process here (I will be doing a much more detailed review of this heatsink with full instructions for assembling the heatsink and results from testing some other Slot1 processors and with the fans blowing onto the heatsink and pulling air off of the heatsink) but it was fairly easy. It took me around 15 minutes to put the heatsink assembly together and install it on a processor and that includes time to take photos of each step of the process.
This heatsink has a huge amount of surface area. The very thin and tall fins used on the heatsink combined with the massive airflow really allow this heatsink to keep the processor cool. If you get one of these heatsinks, definitely make sure you have plenty of room. You will need it.
