Heat And Voltage

[BP]

When I first got my D650 to 900 at 1.8Vcore it was hitting 43C at idle and 48-9 under load and it wasn't very stable.

Well I upped the Vc to 1.85 and the Vi/o to 3.45.It's really stable now ,but here's the weird thing.

My temps have gone ?Down? to 39 idle and 43 under load.Not that I'm complaining,I just always thought that when the voltage went up so did the temp.

Anyone have any ideas about this.

Maybe when you increase the VIO it increased the voltage going to the fan header. Not too sure, could be the case though . . . . .

or components aint straining to work

Hey AZZ, can you explain to me how a component, with a lower voltage can produce more heat because it's straining.
Considering P=V^2/R or P=IV or P=i^2R, then the power dissapated by a component is only related to current, voltage and resistance, not by how much it is straining. But I'm open to theories if you've got something.

i cant show you in theory

but i can say if the feed line to a amp isnt big enough then its underfeed and they get hot

try it
when you put biger wire on it it will cool down

I would like to add a little on this subject, I am a master electrician and I could give you some formula's to go by or I can tell it layman's term's. When you have a piece of electrical equipment that needs a required voltage to run efficient, and the required voltage is not there the equipment will work harder to produce the same output as it was designed to do, this will make heat. also if you have too much voltage the equipment will try to dissipate the excessive voltage, this also making heat. I know this ain't in electronic terms , I am a commercial electrician , not a electronics wiz :) but hope it helps! by the way AZZKICKER that was a good explanation with the amp !

your right


and thanx

well im a electronic eng. and if i told yall the way i know then everyone in this foum would be confused

heehee
