How to cool the back of the graphics card? - Page 2

mad mikee · 12-31-2003, 12:48 PM

SVC has some nice OCZ copper BGA HSFs. I think they may work better than tweakmonsters (More fins, think little skivved copper sinks). I stuck some on to my memory and am getting some more next week for my 9700 toaster.

(red for cooking by toasty memory chips), gotta measure the temps next time I am tinkering....

Did nobody see my post about mounting pressure? Damn. Pay attention!!!!

Zoson,
Yeah, I should have read your reply. What you said is true and I have the same DD geforce wb that you have. Good idea, I'll have to look in to that. You may have it on the nose.

Also, the geforce die does not lend to cooling very well. It has a lip around the edge which keeps the center from getting good contact with the heatsink. I lapped mine down with 800 grit and a flat metal ruler. Then used finer grit until the nvidia label was gone.

I lapped mine with 400grit0, but the damn cor0e is really hard.... it really smoothened mysandpaper and made it feellike 1000grit

There are little plastic thermal pads that are avaliable that are normally used for putting between MOSFETS and the heatsinks cooling them, as far as I am aware they are non conductive (can someone confirm this?).

If they are you could put one on the core (only need to do the very centre between all the surface mount capacitors and resistors and then put a heatsink on top of it (may need to mill around the edges to avoid the surface mount components). Then simply bolt the heatsink through onto the waterblock, without actually bolting onto the card itself (just go straight through the holes). That way the heatsink is applying pressure to the middle of the core, pushing it into the waterblock while simultaneously cooling the back of the board.

I dunno, I didn't lap my core at all, I just gooped it up with AS3. As long as you have good pressure it shouldn't matter a whole hell of a lot. The cards were running with crappy air heatsinks in the first place... not to mention crappy air heatsinks that had to deal with the same lip you're talking about.

Zoson,

My appologies about my post. I am obviously not qualified to post here as I have no practical experience with anything higher than a GeForce 4 Ti 4200... so I will drop this thread from my subscription list.

I hope that you can help everyone better... Have a happy new year.
