Once I realized that my r9700 was maxing out at 334/324 i decided it was time to put on a new heatsink. I'm upgrading from the stock heatsink and fan to this combo :

Anyone ever put a cpu heatsink on a gpu or am i the guinea pig? I'll be attaching this with some screws. I'll also have to plug the fan into the mobo seeing as the card does not support the 12 v fan.

Nice but you're not the first. Alot or people put 1U HSF on video cards and that's what I recommend you do, cause that's a bit overkill and is alot of weight for the card.

No.

The fan on my 9700p died, so I took it out and strapped a 40CFM 80x80x25 on there with POTS wire. Works fine.

Update i'm ordering a sunon hsf tonight since my stealth hsf doesn't seems to be bottlenecking my cpu oc, so i'm thinking of drilling holes into the hsf and attaching the stealth fan to it. Will a stealth move more air than an amd retail fan?

blackhawk; you'd be surprised. I've got (or I did @ some point... I may have lost it/given it away or something... I dunno... I have too much computer crap to keep track of it all) a heatsink that looks just like that, and it doesn't weigh that much- it weighs less than AMD's max. recommended weight anyhow, so it's got to be less than what, 350g? So it's not that bad...

Well, i got the dremel out and marked a few areas on the heatsink to cut with a sharpy. Looks like i'll need to do some sanding and lap the base . Damn dremmel's too hard to control :shakehead

you're supposed to control the dremel, not let it control you. Sheesh... whad'ya do- let it run wild all over the thing? It's a mess! :D ;D I mean I got MY cuts perfectly straight (OK, OK, so I EDMed the thing... so what? :rolleyes: )

J/K... it's actually not bad @ all... especially compared to my work with a dremel. I've started wearing gloves when I use it. I'm dangerous with that thing... :rolleyes: :D

Indeed, the dremels do have a tendency to get away from ya! :D

Been there, done that.

What is the best tool to get rid of the shim? Its glued on pretty hard. A stiff razorblade?

Eh... I saw a thread on hard ocp where aguy took off his shim and along with it some vital chips for the card. Why do you want ot take it off? What is the purpose of it too...

To be honest, i dont know what the purpose it has. You will get much better cooling without it cause the core is actually lower than the shim. You get MUCH better contact without it.
My waterblock doesnt have great contact at all so i cant really overclock the card.

mack, if there is some way you can cut out a depression in the sides of the waterblock to clear the shim, it would probably be safer than taking the shim off (the card is more expensive than a new waterblock). I'd think a stiff razor blade would work fine tho.

EDMed?

That's a good, short definition of a Wire EDM, which is what I used to cut the notches in the heatsink on my 8500... my grandparents own a precision machining company, and we've got a bunch of both wire EDMs and sinker machines (on sinker EDMs, the electrode is a rod).
