HD4870 Noisy Fan

That seem to be too hot. Are you sure that the heatsink of the GPU cooler is properly sitted and the thermal paste are leaving no gap between the contact of the heatsink and the chip?

If you can show us a picture of your graphic card's current state that would probably be helpful.
 
I'm fairly certain there's no gap, it's really nice and tightly fitted. Could the higher temps be a result of the fan being directly over that extra heatsink on the side? i.e hot air being sucked up into the fan and blown through the system?

The temperature does seem to be coming down a little though, maybe the thermal paste just takes a while to set in?
 
What a palarva, seems ludicrous that the manufacturer can advertise that as compatible if you have to mod the card so extensively. I ended up chucking a Thermalright HR-03/R600 Cooler on my 4870 with a 92mm Fractal fan, working a charm, idling in the 40's now. That temp seems pretty high, I'd check to see if it's seated correctly.

Can you take a picture of your graphic card showing how's the thermal paste applied (without the GPU cooler on)? Because with temperature that high, I can't help but to think the heat from the GPU is not being properly conduct/tranfer over to the heatsink of the GPY cooler...could be paste problem, or could be sitting problem.
 
My camera battery is dead after taking lots of photos and videos today. All I can say is that the entire chip was covered with an even layer of the paste, completely covering it, that is definitely not the problem. Maybe it's a seating problem, maybe it's something else..don't care anymore to be honest. I've wasted this entire day trying to get this piece of junk to work.

I've just put the stock cooler back on and i'm idling at 50 degrees. Interestingly, if I put the fan on at 100% it only goes down to 49 degrees so there's clearly something wrong with this Akasa crap.

Unless there's something else I can try with this I think I'll be sticking with my jet engine cooler, it's loud but it works. £20 down the pan.
 
I received this reply from OC tonight...

'Im affraid VGA cooloers only work with certaing model and revisions of card, if this does not fit then you will need to find another cooler that will if possible, otherwise you will have to stick with the stock cooler.'

Bit of a kick in the teeth, could have at least taken the time to correctly spell their reply 'sentence'. He obviously bought a 12 pack of stella with my £20 :D At the very least I would have expected a little, 'oh we're sorry about that, we will update the product page straight away'. They clearly list the card on the product page as being compatible so that reply just annoys the crap out of me. I've lost my entire day, I've hacked bits off my graphics card and i'm now £20 down.

Anyway, thanks very much for the help with the cooler today, much appreciated. At least I learned a few things about how this stuff works. OC have messed up my original order and now they've screwed me on this one too, so needless to say i'm done with them. Take it easy :)
 
i had the same problem, but with a different aftermarket cooler - had to buy a seperate cooler to go over the vram chips which i think the heatsink for which the op had issues taking off.

with a sep cooler for the vram my card runds quiet and cool about 50oc after playing cod2 for hrs
 
Zalman did a cheap as chips VRM heatsink specifically for the 4870 card iirc. It was similar to the black heatsink in one of the above pictures, but orangey-red in colour.

This problem is not exclusive to the Vortex NEO by the way. I remember similar problems being reported with a few different coolers. I'm using a Coolink GFXChilla on my 4870. Works great (and is pretty darned quiet), but I had to spread out the fins on one of the RAM sinks to accommodate the heatpipe on the cooler itself. If you didn't do this, the GPU cooler wasn't allowed make full contact with the chip, even though it looked like it may have been flat.
 
also I don't have a separate fan on mine it sits infront of my CPU cooler and behind another fan. depends on the rest of your set up
 
Well since your card is a non-reference design I wouldn't be too surprised about it, I had to return my waterblock because both of my HD48* cards were non-reference (reference are usually red PCBs).

They should at least add "reference design only" in the compatibility table.
