Bij HardOCP is een vergelijking verschenen tussen een flink aantal SocketA heatsinks. Totaal worden 22 heatsinks besproken en getest op een 1,4GHz Athlon @ 1,6GHz. Van de 22 heatsinks zakten 7 voor de test omdat ze de processor niet stabiel konden houden. Uit de 15 heatsinks die dat wel konden is de Cooler Master CB5-6G52 een verrassende winnaar. Deze heatsink wist de gevestigde orde bestaande uit onder ander de Thermalright SK6 en Swiftech MC462 met 5° F te verslaan. Een tweetal stukjes uit de conclusie:
Remember that this HSF in its stock form does not come with a high performance fan. To get the performance we did, you will have to invest in that extra. We have not been very impressed with Coolermaster products over the years and when I pulled this one out of the box I was far from impressed. One thing we have learned about HSFs is that its looks have nothing to do with performance. Reminds me of a girl I knew in college. This is a heavy solid built unit with a very nice clip on it. These are not out for sale as of yet but Coolermaster products are very reasonably priced usually and they did just show up on the Coolermaster spec pages as linked. The 7K fan on this unit is a bit loud like all 7K fans but our CB5-6G52 unit when mated with the 8K fan is simply awesome. Take note that the 8K fan, while it moves a tremendous amount of air, also sounds like a small jet plane in your case. Also, I highly suggest a grill guard fan. You fingers might one day thank you.
[...] Copper coolers are here in a BIG way. Don't waste your time looking at all aluminum coolers if you are wanting performance. We knew it was moving towards this and actually happened sooner than we thought. Remember that the system we used to test did stress the HSFs very well. We estimate the CPU was producing over 92 watts of heat that had to be dissipated. Also worthy of mention is the fact that the 1.4GHz TBird is the last (and the hottest) of the Athlons. The desktop Athlon4 is on the way and using the Palomino core it will run cooler. Most likely any high performance cooler will do a great job down the line if you intend to stick with the AMD family of CPUs.
