It ties at load, and performs worse by 1 degree when idling. Within the margin of error, I suppose, but surely I don't think it performs noticeably better.
Also this is a single core benchmark, its not nearly enough to use the cooler effectively.
So you mean you need the IHS removed for the Sonic Tower to work effectively?
Sorry, I don't buy your argument that all heatsinks work the same at low load.
Single core ie: amd 3200+, not refering to the IHS in any way.
At low heat outputs whats limiting the temp is the thermal interface between the cpu and heatsink, remember no heatsink will cause the temp to be equal to ambient even when it disipates more heat than gains, why do u think that is? Also this is the same reson u get better temps with the IHS removed, u get better thermal interface.
So at low heat output ie amd single core cpus which dont produce nearly enough heat, the heatsink will perform same as any other for that exact reason. And i have tested this by comparing it with a blue orb 2. I put the blue orb on the 3200+ amd, checked max temp then i replaced it with the sonic tower. And the performance of the heatsinks was the same.
When i did the testing on my 3800+ amd X2 overclocked to 2.6ghz (back then

) the sonic tower had much better results, like i said before roughly 10+ degree diff at full load between it and the blue orb 2.
The thing is the heatsinks have the same temp transfer capability from the cpu, they both have coper bases. So if u count this similar then if the heatsinks can disipate the heat that they gain their temps should be equal. Now when u apply more heat, whats gonna happen is some heatsinks will still be able to disipate this heat without buildup (this is where heatpipes are actually usefull cause they transfer energy quickly) and some will start heating up cause there is more heat then they can disipate, they will heat up to a point where the heat they recieve is equal to the heat they disipate.
So based on this to really test how effective the heatsink is, is to get to this point where u see that happening, cause bellow that there is not much point.
