Why don't mobile proccessors have a "cover"

post #1 of 8
Thread Starter 
I wish to buy a mobile processor because of the potential for overclocking due to the lower voltage, but I can't figure out why the mobiles don't have that heatspreader like the other ones do.

I desktop processor will have a smooth protective cover over the die, but ones such as the Mobile Athlon 3700 do not. Why?

In laptops (where mobiles are used), the chips would get so hot with the cover (Integrated Heat Spreader - IHS) that they'd overheat. Not using an IHS to protect the core allows for better heat flow from die to heatsink, therefore lowering temps.

You too will get better temps if you remove your IHS. You just have to have serious testicular fortitude...

How do you attach an extremely heavy heatsink to a processor if it has no protection. Would you use thermal tape to prevent the bottom of the heatsink from touching the die? Or is it ok to use themal paste and rest the heatsink against the die?

The mobiles are like the Athlon series with no heat spreader, I have three with typhoons, you should have no problems.

I thought they didn't have mobile a64s just turions. Do the mobile 64s run at a lower voltage than their desktop brothers?

mobiles are "laptop" processors. Laptops need the best cooling possible, and mobiles are said to run hotter than normal chips anyways. Make sure your motherboard supports mobile chips, alot dont. A bios flash could fix, but probably not.
If you are looking into a mobile, I highly recommend the "Newark" cores, they are by far the best overclockers with 1M L2 cache..

Laptop's need to conserve space, so not having an IHS helps do that. Also, laptops have small heatsinks, so mobiles don't have IHSes to allow the CPU to run cooler. And lastly, not having an IHS allows the CPU to run without error at higher temps, IHSes spread the heat out, so the heat can damage the processor whereas processors without IHSes can withstand higher temps because all of the heat will be on the core, not spread out around the whole processor.
