evga 680i heat sink

[bazx]

been looking around this m/b today and noticed that this heat sink does not make contact with the chips once the cpu heat sink is fitted

i removed the sink to find that out of the 6x chips under there only 2x (one each end ) were making contact and the m/b had bowed due to the pressure
from the cpu heat sink

anyone no what these chips do ? as they get very hot and will need to be sinked individuly

I think it would be better to have no heatsink on it, just put a fan near it that should be enough.

Or just buy some small copper heatsinks and sink them invidually.

[ryaan]

sink em individually if ya need.


i feel bad for all the peeps with 680i's... so many problems with em.

they are power mosfet's buddy, most mosfets are real robust and can take quite a bruisin'. UPto 60 degrees for 24/7 use does not affect theuir lifespan too much at all.

Individual heatsinks are a good idea with a smal fan accross the board to keep them between 40-50 degrees.

its good to here they can take some heat

i will be sinking them Individualy

this sure is a thin pcb

this sure is a thin pcb
my thoughts too, the first time i looked at this mobo. 6 layers?

it bends like paper, this in its self could be its down fall once resistors start to
ping off it lol

and the cpu could do with a back plate as it looks like the heat sink is pushing the cpu through the board

and what heatsink arre you using and how freakin hard are you tighting it down.
if your tightening it down enough to flex the board enough to see it, and also to make the mosfet heatsink not touch then dude your tightening it too much.
ease up a bit eh

it is a shame you nothing of this set up

the stock intel cpu heat sink is not screwed down

it has a self setting sprung loaded retaining clip which sets its self for tension

and requirers only that you push it into the holes provided in the mother board

where it sits with no back plate

edit

i see from you sig you have one of these m/b have you even looked to see

how your board is doing and indeed if there is any contact with the mosfets

[Lestat]

thats ok i dont know anything i'll return to my hole in the ground and let you figure it out

Sounds like the old s478 boards with the stock mount brakcet used. Would make the boards look like this after a bit.

Not that deep but you get what I'm sayin. Would warp like a U where socket was.

i used the zalman backplate (for 9500) to mount my tuniq...the one i recieved was flat enough, but for some reason, i couldnt get it to work with this mobo (the backplate) it was like my mobo was flexed a tad...anyways, i used the zalman backplate....not sure how it will hold up once inside the case....its been sitting on the box, while i keep benching it....lol

thats pretty much it lol

the zalman back plate is a good idea

after next week it will be going hook it up to a cascade so will get plenty of support then
