Yeah--I've done that once already. I initially coated the entire top surface of the chip with AS5...then, realizing I had erred, I followed Intel's / Arctic Silver's recommended placement of the thermal compound. NO change in temps.

What I am wondering: Is my 7000A truly flush against the chip? Using Zalman's 755 adapter may raise the bottom of the 7000A *JUST* enough so that there isn't a good heat transfer away from the chip.

That's why I want to try the Intel stock cooler. Granted...it may be be as "good" or efficient as my 7000...if it is flush against the chip, it will probably cool much better.

Thoughts?

Your temps seem too high for that cooler. I am using a 7700cu at the moment, also running my E4300 at 2.7ghz, stock volts, and only hitting ~65c load in a rather hot ambient temp room (28c or so when I stress tested).

Have you checked that the fan is spinning at max RPM's? (~2000)

My fan is indeed turned up to max rpm (should be showing that in my screenshots, first page).

As I may have stated earlier...my only conclusion is the one thing that remains: The 7000A-Cu is not fully seated (or making contact with) the C2D. I'm using the Zalman ZM-CS1 adapter (http://www.zalman.co.kr/usa/product/...x=143&code=009) to fit my 7000A to my Asus P5LD2 motherboard, so if my 775 socket is within specs and Zalman's adapter is within specs, everything SHOULD be well and good--the 7000A-Cu is a beefy enough HS to leech away most heat and energy from the chip.

I'm thinking that, by ditching the ZM-CS1 adapter and the 7000A HS, and going to the Intel stock HS, I might see a drop in temps if the Intel HS makes better contact with the chip. It'd be a gamble, costing me only time, to find out if chip-to-HS contact is my demon here.
