As has been said, overclocking of any kind will result in more heat being given out... the reason for this is that everything (except vacuums?) have a resistance, and every time an electron goes through it gives a bit more heat out. Increasing the FSB will mean more electrons going through at one point, so more heat.

As the northbridge is the central nervous system of the mainboard, most active cooling happens here (it helps that the rest of the motherboard has a huge surface area compared to the northbridge to dissipate heat passively).

But most motherboards have a heatsink if not a fan on the northbridge, so will allow for at least "preliminary" FSB overclocking...

As for the 760MP(X), the board is manufactured for stability, overclocking is not a high priority for duallies. You might get a bit out of it, but make sure its rock-solid stable before you start, that's a LOT of heat in that case...

Have fun ,

If I remember correctly, Superconductors also don't have any resistance. The only reason they don't make more of them is because they need to be made at around -150 degrees C. Would be nice to have Athlons that would run without a HSF, eh?

Well, i'm not sure they don't have ANY resistance, I know at least that they resist significantly less than semiconductors.

Anywho, yes.. I realize this will be one fairly hot case. Which is why I decided to wait for the TBreds, and not go with a (even hotter) Palomino. I will run it at least for a week folding, which is about as hot as I can push it. I can't get a big case, because I want it to be able to fit in my bags (I'll be taking this on a few airplanes in the next month or two, to LAN events). However, I can still fit a midtower ATX case in there, and that should be ample for a dual CPU system. I'm shooting for a Lian Li PC60, and packed with fans.

Thanks for all the info!

Superconducters have a very very very very very very.... low resistance yes. It is far less than normal materials.

(out of depth speculation)

The reason I suggested a vacuum might have negligible resistance is because resistance occurs when an electron goes from the orbit of one atom to the next. If there are no atoms to get in the way, there should be no resistance, right?

(/out of depth speculation)

Anyone know anything about this? I'm sure TwoFer would do it in terms of a really complex equation or something ,

Personally, I love AMD chips because of their heat...during the winter time we all just gather round the ol' Athlon 1.0 @1150 and roast marshmallows. My electric bill is about $50 cheaper during the winter than my neighbors-no central heating needed

Reminds me of putting batteries on my tongue

However, there's probably a bit more current in a 400W PSU ,

While we're on the subject, your original post reminded me of an ad on the telly at the moment in the UK...

This woman spills her bf's can of drink (can't remember what it is, so it's beer now) and he licks it up... she then proceeds to pour it over the kitchen floor, the bathroom etc.. He licks it all up and in the process cleans the whole house...

Then she runs out when she starts trying to put it on her body ,
