Alot of reviews i look up always come up with completely different results. I could look up a SI 120 on one site, and look on another site and get completely temps and opinions. Its making it really hard for me to decide. My swiftech MCX6400 heatsink on a stock 3700 sandy idles anywhere between 31-33c @800rpm's, and when i'm playing far cry its load is only about 38c.
Whats killing my temps when i'm overclocking is prime95. I had my cpu at 250x11 with the voltage in the bios set up as 1.475v (shows as 1.408 in cpu-z). My load temps in prime95 were 51-53c, which is too hot for my taste. Infact my computer locked up after 11hrs of running the program. The main problem was that i was getting a parasitic temperature increase, i noticed that every 2hrs or so while running prime95 that my chipset temp, and cpu temp would rise 1c. So just think what it was at while i was sleeping in the middle of the test.
This is why i wanna get a different heatsink. I do want to go phase change, but it doesn't seem that ocz is coming out with their phase change for a while yet, and i'm not spending $800+ for a vapochill or something.
