How do I aftermarket cool a 5870? - Page 3 - Overclock.net

@ Optical sorry to say but you are wrong. The gpu sink and the baseplate are welded together on the 5870... that option is gone. The 5850 on the other hand, you can do that.

That is why I am having some issues with cooling and trying to figure out what to do, what exactly needs to be cooled how hot is this running and that sort.

The issue is not the gpu cooling but the VRM cooling.

Interesting, is the baseplate welded together for all versions of the 5870?

I wonder if this will work?

Some memsinks may be enough on the VRMs provided there is plenty of airflow over them, still at this point I would be inclined to stick with the stock cooler and wait for someone to confirm a working effective solution. You could contact someone with CNC machinery (iandh or duniek spring to mind) to custom fab something, but that would be mucho expensive and you would likely have to send them your card.

Optical that will not work either lol. The VRM holes are bigger then the 4 series and you would have to fabricate your own holes and don't forget change the dimensions around since that won't fit either since the layout of the board is different. The VRM's on the 5850 is cooler then the 4890 and 4870, issue is, I don't know how hot the 5870 is. I already have a Zalmen 70 heatsink for the VRM cooling so like it will be fine. Here is the link on the 5850 cooling I have found and getting ideas off of it: http://forums.overclockers.co.uk/sho...062457&page=11

To cool the VRM's well, you just need to have allot of airflow or a giant heatsink to cool them effectively.

Ok so they tested the Musashi and from what I can tell they are still having issues cooling the VRMs (like Nick said)...suggestions?

Honestly I am a bit surprised, I would have thought it would have cooled slightly better. It definitely is quieter which would be good enough for me to go with aftermarket cooling, but they need a solution for the VRMs first.

I have a solution instead of a suggestion,wait till I'm done with my testing of the 5870 and my style of cooling then decide if it is not going to work.

Notes:

Zalman VF 1000: The testers are idiots, they didn't use the cooler for the VRM's that Zalman produced like this: http://www.cooltechpc.com/ctpc/image..._installed.jpg , sure you might have to drill a bigger hole to fit it over the area but modding is what we do! Maybe that I'm going to cool my 5870 like that ^_^(gota stay tuned)

First off, the musashi can cool fine, just need some type of metal on them and you will be fine. Overclocking? Doubt it

Accelero S1: WHAT ARE THEY THINKING!!!!!!!!! You are supposed to use a R2 S1!!! That will fit and work! Also it comes with VRM cooling! That really ticked me off when I saw that. http://www.overclock.net/hardware-ne...ork-gfxmod.jpg that is how it is done!

Man, I should been there to help them with this since they have no clue lol. Watch my solution will work.

Lastly, I'm glad to see the http://www.techpowerup.com/reviews/A...front_full.jpg (were the white sticker is) I know know full well that it needs to be cooled properly. The card can be cooled efficiently, just have to be creative.

Looking forward to what you come up with Nick...although...will your solution work for 5850s as well? I think I will be going with a 5850...

Nick911 · 2 Weeks Ago

As long as the spacing from the gpu area(distance from one gpu hole to the DVI area is the same as taking that hole and measuring it on the 5850 to the DVI area) , then yes, my solution will work and have no issues.

That sucks, guess we're out of options for now.

I wonder if the base plate on the Vapor-X models can be kept on.

Going from this picture:

Can't really tell if the base plate can be separated from the heatsink.

can't be taken apart. Were not out of options until I post my results
