Aftermarket Cooler For 4850

The PWM's may not have a ton of airflow from the Vortexx but maybe its enough? I'm gonna have to re-read this thread as I'm not quite sure if the Vortexx is supplied with PWM heatsinks or what?
Are they cooled by airflow alone? or are they wedged under the butt end of the Vortexx's heatsink?

No heatinks supplies, cooled by airflow alone.
You could do this if you wanted.
Sorry for bad picture. Wayne you can work your magic if you want.
Those are a couple of Enzotech BMR-C1 memory ramsinks.
Canny fit on the big chunky things but the Zalman ones fit fine.
ps....i have swapped cards round and swapped the neos....still the top card gets very hot...there is nothing above the top card to stop air flow....but it is hot to the touch...the bottom card is only slightly warm
top card idle temps 60c
bottom card idle temps 44c
top card idle temps 60c
bottom card idle temps 44c

Hmmm well that's not ideal.

If the cards fitted with a Vortexx don't overclock as well as cards fitted with an S1 then we may know the reasons why.

I would have thought this was expected. The top card is essentially sucking in air from below it - which when in a twin card setup it is generally the warmer air coming off the back of the bottom card.
(edit - also noticed the water pipe running across the fan area of the top card cooler. This would also be giving off some heat, unless its a feed just after the rad.)
The bottom card has a lot of cooler air below it so will generally run cooler.
Seems fairly logical considering that heat rises?
I wouldn't worry about it as the top card is still running cool for a GFX card.
You could test this theory by running the system with the case on its side - if the temps balance out, then thats your problem.

I think it should.
Apparently the if it can fit the 3xxx series it'll fit the 4xxx series. Or so I've read. lol. Would hate to buy one and it didn't. 
I'm using two HD4850's in a system with straight passive cooling with the Accellero S1. You do have to open up the fins with a screwdriver, but they bend back once the Crossfire cables are in place.
It works extremely well for me, (40C Idle, 65C sustained load) but I am running an unusual case configuration with the Lian Li S80B with three fans blowing into the case, and none blowing out, so the air is forced out under pressure. Because the Accellero S1 comes with slotted back-plates the pressurised air comes gushing out and that's why I think they work so well for me. If I take the inner side panels off (total pressure loss) then the temperature goes up by about 15C at idle.
I've nothing on the VRM, and the basic RAM sinks on the RAM, which are next to useless to be honest, but they've been folding 24/7 for about 2 weeks now with no ill effects that I can see so far.

Looks good WJA96!
Think you may be losing a heatsink on the bottom card/left!
Did someone rush the installation?
It's not going anywhere... The sticky pads they use aren't up to the job. If I can be bothered then I might sticjk them back with Ceramique permanent, but that's quite final, in a 'never coming off' kind of way.
