That's not really the point is it? We're talking about crap heatsinks here. I don't care what kind of CPU its cooling, a thin metal plate is a crap heatsink. Maybe if it had some fins or something... but this is just smooth on top.

It gets awfully close to that temp sometimes when turbo mode is on (2GHz OC).

Hmmm, how about the Asus EEE PC 2G/4G models?

Dissipates heat into the plate below the keyboard, and the fan sits underneath the motherboard to expel hot air

The point is that a good heatsink is one that can deal with the heat load present at the minimum cost while fitting in the physical space available.

For an Atom, a copper monster with heatpipes and fans is a terrible cooler, because it won't fit where it's needed and the cost is too high. A small plate is a perfect cooler.

For a 980X, a single plate is a terrible cooler, and you need something a little more complex to deal with the load.

You can't compare the two and say one is crap without knowing the design constraints. It's like saying a Ferrari Enzo is better than a Ford Focus. While that's true on the track, what if you need to do the school run with 3 kids?

Similarly stock heatsinks & server heatsinks. They aren't crap at all, and do the job they are for at the lowest possible cost. If you want more performance, you pay more for a cooler that can do it. But there's no point Intel shipping a Silver Arrow with every CPU and doubling the costs to end users when most of them will sit at idle in people's PCs while they browse the web.

The really crap heatsinks are the 3rd party aftermarket ones that promise lots, often cost a great deal, but perform worse than the stock fans they replace.

Ok, ok, I agree with you...

I guess I just hate it when OEM's half-ass things. So tired of people coming to me with issues like "my laptop keeps shutting down" so I turn it on and the temp shoots up to 100C. Then I take it apart and not only is there a heatsink the size of a toothpick shared between the CPU and GPU, and a single fan the size of a quarter, but there's a half a tube of TIM dumped on the chips.

EDIT: More laptops need stuff like this:


No reason they couldn't work something like that into a 15" notebook that has dedicated graphics.

True - but there's also no need to do that in a netbook or similar.

And most laptop coolers I've seen run just fine and keep everything well within spec - that is until the owner puts the computer down on the couch and blocks the air vents or fills them with dust/fluff and everything starts to cook...

Yea, much of it is user error. I'll never understand why computer manufacturers can't figure out how much TIM to use though. Sometimes its not so bad, but the last laptop I worked on (an acer) had so much that a quarter inch strip of it had squeezed out and ran all the way around the CPU. It was all over the motherboard. Took me an hour to get it all completely cleaned off.

Its called they are trying to pump them out at the highest volume possible. Well you or I will spend a good 5-10 minutes making sure it is spread out perfectly
