Those heatsinks are awful as far as performance goes.
post #42 of 107
Doesn't really matters that much, heat sinks in general i mean. Old generation boards mattered alot, back in the p45 days metal skrews vs plastic skrews made lots of difference. Also duo to high number of phases, the heat output is low.

A bare board with no heatsinks look quite ugly.

On most IB boards, the heat output of the VRMs wasn't that much. The need for robust heatsinks on mainstream Intel boards simply isn't there. They can afford to make the heatsinks more aesthetic oriented than performance oriented.

Besides, though they have that flat cover on top, in other pics, they have fins parallel to the board. It's different from the usual perpendicular fins, but they are there. Can't judge a book by its cover.

idk i like boards without their heatsinks. You are into computers, how can you not want to see the hardware that is powering everything?

From a purely thermal perspective, the whole purpose of a heatsink is to soak up and dissipate a certain amount of heat generated.

As long as the heat output generated by the VRM can be properly reduced to normal functioning thermal levels, this design will work fine.

Both of the statements above show a complete lack of understanding of how thermals work. If you think these suck, I think everyone would be horrified at the ES samples used to qualify motherboards in general, since surface area on those are a hell of a lot smaller and do worse.

Case in point:


Note the X79 chipset heatsink, and compare that to most "enthusiast" offerings... what we have in the end user space is complete overkill for what the board would actually need.

Good points. As far as I understand it (I'm an ME, not an EE), the more phases there are, the less current goes through each. Less current leads to lower operating temperatures and higher efficiency (usually). While the amount of heat being dissipated is nearly the same (a bit lower because of the gains in efficiency from mosfets operating at lower temperatures), it is being removed much more efficiently.

True, but it's not even like that... note the size of heatsinks.

Heatsinks are much like box art or color scheme or packaging... just a way to differentiate your product in a marketplace full of the same product(s).

Oh my... they had better heatsinks on their samples! tongue.gif

Right. I'm saying that the heatsinks become more and more overkill as manufacturers keep adding phases to boards. A good majority of boards can likely run without heatsinks these days.

As long as the heatsink does a good enough job to keep the VRMs cooled, it's only the design that matters. The M Power heatsinks look absolutely gorgeous, nice and hidden, great design.

ASUS' new boards on the other hand, my God.
