The problem is the heatsinks on the P35-DQ6 are not only too tall, they're positioned all around the LGA in close proximity, making it difficult to fit anything other than stock Intel coolers on.
yup, the thing is, every mobo ever made can accomdate the size/area that sink takes up, you just have to use a small amount of brain power to locate that heatsink out of the way, just relocated 2 inches to the left, where there is nothing, and wouldn't interfere with anything doesn't seem hard to work out, yet they didn't.
Just seen pics of the gigabyte p45 extreme while trying to decide on a new motherboard to get, its got an insanely sized sink but its very slim, and extends miles out from the mobo, it shouldn't really interfere with anything.
Frankly cpu, and gpu heatsinks all have SO much space to use as almost all normal cases sold have so much space between the end of a gfx card and the side of a case that heatsinks could sit around in.
I'm completely ridiculously confused about motherboards though, my system right now is crashing in so many varied ways I have no clue whats actually at fault, replacing the normal things has done nothing so far. thinking replace mobo and Gigabyte have 24 various boards JUST for the P45 chipset, another 8 or so for P43, another few for the X48, its just such overkill. Doing my head in trying to find the right board at the moment.
Half of ASus's boards, and others, have lovely little things covering heatsinks with their logo's on, ASus do it so often, my 975x i think it was had a massive sink on the northbridge, with a loverly , connected by glue, cover blocking 90% of the case airflow getting to it, why? I have no clue.
