Huge Temperature Range on C2D

[alphahoke]

Yesterday I installed a new heatsink on my baby E6300 to try to pump it up to ~3ghz. The heatsink I chose was the Scythe Orochi SCORC-1000 which is an incredibly large piece of hardware. It seems more appropriate to say that I installed my motherboard onto the heatsink, and not visa versa

In any case, once things got up and running, things were running at a cool, stable 2.66ghz at 37 degrees idle and...55 degrees under load.

Wait, what?

That's a 20 range between idle and load. Something seems fishy here--won't that be harder on the chipset? Did I do something wrong?

One thing that I'm considering is the fact that the Scythe Orochi SCORC-1000 is semi-passively cooled by a slow moving fan that doesn't speed up when temps get hot. Ideas? Thoughts?

20 degrees is nothing. Did you check the temps before you OCed it? And on stock cooler surely your max temp was higher than 55C. I routinely saw a 60 C difference between idle & load before I switched to an aftermarket HSF. Now a 30-35C difference is what I expect.

PWM capable fans and motherboards will result in fan speeds that vary with temperature. However no worries about your fan - according to this review your HSF is intended to run at the same constant and presumably quiet speed: http://www.frostytech.com/articleview.cfm?articleid=2258&page=2

The review also shows a 21 to 34C rise in temp over ambient based on processor so your findings don't seem too far out of the unexpected range. Unless your ambient temps were say 15C. http://www.frostytech.com/articleview.cfm?articleid=2258&page=5
