For an AM2 or C2 Intel model you would use the 9700 not the 9500.
By C2 I assume you mean Core 2 (Duo)? If so, why would it make more sense to purchase the 9700 over the 9500? The Core 2 Duo's consume 65w of power (much less that AMD's) and meaning it's cooler.
the 9700 utilizes a bigger fan, the 9700 is 110mm fan while the 9500 has around 90mm
The Tuniq Tower 120 is cheaper and betterwhatever it takes to squeeze out those few extra temps down.
While the 939s max at 70C the newer AM2 and Core 2 models max at 60-65C. The newer they are the more temp sensitive they turn out to be.
When you pay a visit to coolerguys.com and look up the C2 catagory you won't find the 9500 in it. You have to go by the models recommended for the Core Duo or Core 2 Extreme and not 939 or P4 models.
My 4800+ X2 939 stay's at 50*C full load (max heat test in Prime95 for 45 minutes) so I can say the 9500 is a really nice cooler. altough, I cant advice using the thermal paste that comes with it, I used the Zalman ZG STG 01 paste, and like said, it works great
What? I don't understand... Are you saying that because the people at coolerguys.com use only the 9700 on C2's, that it makes more sense to purchase a 9700 for a C2? I'm confused...
The 4800+ runs hotter than the 3500+ (110W TDP vs 89W TDP iirc). The Zalman super grease is just as good as AS5 and you get a giant bottle of it instead of a little tube.You are seeing 50C? I load the heck out of the 3500+ single core model to see it max at 40-43C tops when multitasking with video capturing, multimedia, and other things after literally running day and night. Have you tried Artic Silver 5 on it? I never use the cheap stuff that comes with any of them.
When you click on the cooling link seen in the left column the various types of cpus are grouped together as you see from the image here. Once you make a selection you then see a new page open with the model best suited for the line you choose like for Socket 939 and Pentium D you may see the sa,e page open. The coolers there are compatible for those boards while AM2 and Core Duo boards have a different way of mounting the hsf on them.
