That could come in handy..../formulates criminal mastermind-type plan that leaves no fingerprints....

I actually have good air flow in that case and it is heatsinked. It doesn't stay cool but it's not what I would call hot. So to answer that I have touched it and I still have my fingerprints.

but see you must not understand that they are actually quite cool. Only the NB Phase is warm and thats only because I didnt stick a heatsink on it. and dont say that adding heatsinks is unfair because the reason the 4+1 thingys exploded was from current, not from heat. they will explode no matter what temp they are if I draw too much power from them.

updated screens too, with more volts

In regards to 4+1 or 3+1 boards, would higher amperage from a quality psu make any difference? The way I've always understood it, more amperage available allows the components to pull less, and thus run cooler.

Are you really going to negate your own argument with your first statement?

no, thats not exactly how it works. the 3+1 power phases are the limiting factor for power draw, and no matter how much power you can put into the input side, they can only convert so much of the 12v power into 1.5v power, and thus are the PSU makes no difference as long as it can provide the power that is being pulled by the system.

no actually, because I didn't specify which were cool and which weren't. but arguing over little niggles like that is pointless. My point about the current vs heat still stands.

Makes sense to me now, thanks for the explanation.

its just that less phases leads to more chance of burn.

since I can push 1.584v though this 3 phase, I am really thinking the exploding deal was either A) a bad batch of inductors or fets OR B) people running prime all day like idiots.

I give you props for pushing it to the extreme on that motherboard_ a tad bit scary (but if it does blow up/catch fire, it is a cheap motherboard and easy to replace so I suppose its not a big loss)
