sorry, i didnt get the 2nd paragraph
you mean to say that all 4 copper pipes should be in contact with the cpu
Also i few pages back a member chinesethunda said "the fans are too big and stick over my ram slots"
on his Gigabyte GA-H55 LGA1156 and i am worried if my Asus M4A87TD EVO will also have similar problem as ram slots a closer to the cpu
Yes. The 4 copper heatpipes absolutely HAVE to be in full contact with the CPU for the heatsink to function. If only the grey aluminum of the base comes in contact you essentially render the heatsink useless as it's ability to transfer the heat to the heatpipes would be greatly diminished.
The theory is that filling in the gaps will help with the heat transfer, but my tests have shown that not to be the case. I've tried applying the TIM just about every way imaginable except for applying the lines directly to the heatpipes themselves and I'll be trying that early next week after the Chimp Challenge is over.
As for your motherboard, the ASUS M4A88TD-V EVO/USB3 seems to be okay. Not sure how much difference there is between that and yours though. But unless you have the really tall heatspreaders on your ram you shouldn't have a problem. You might need to slide the fan up just a bit to clear the ram closest to the cpu, but that should affect cooling enough to worry about. Maybe 1 or 2C at most, if even that much.
