** Prolimatech MK-26 Multi VGA Cooler - R9 280/290/290X Compatible

Ah I see. I think I remember Gibbo mentioning you'd used epoxy to secure the heatsinks. How come? I'm sorry for all the questions, but I'm sorely tempted by this and I just want to find out what the deal is. :)

Right then

Some more information here to answer drunkenmasters questions and hopefully explain a little more about the setup on this card.


this is the board layout and shows where the heatsinks go and what heatsink from which kit we are using.

Cheers for the pics, very useful to know how it might fit, can save £50 which in this case due to rma/shipping issues I can completely understand being an increased cost. Every time I thought of selling and sending off my 5850 or them 6970 with the prolimatech installed I could only envisage it turning up broken and battered. Wouldn't exactly fit in the normal box with that big mother of a heatsink on it :p

Bit of a shame AMD didn't have these out a couple years ago. I've said for years that there isn't anything physically stopping AMD making a card inbetween the 420-550mm2 size, they just didn't want to. Had they done so they'd have beaten Nvidia every generation for 5+ years. A 438mm2 core beating a 550mm2 one is great for them and being that they are still sub 450mm2 the yields will be way higher and would be viable much much sooner.

I still think price is probably going to push me towards a 290 non X. Nice to know there is a decent compatible cooler around already. If I win the lottery, 2x290x's :p
 
Imo OcuK would be better off restocking the Arctic Accelero coolers. Though a shim would be needed i suppose until Accelero officially supported the 290X. It would be cheaper and probably quieter for similar cooling performance. However they could use better heatsinks to attach to the vrms. I'd definitely be interested in a pre-built Arctic Accelero Extreme for the 290X.

EDIT

Turns out a shim is not needed!

Has anyone mentioned if the MSI agreement where we can carefully fit after market solutions applies to the 290x? If so, I'd be interested to wait and see what new coolers are coming in with their next shipment.
 
Hi there

Right guys, being stress testing this solution over-night and all day to day.


At stock speeds, voltage reduced too 1225mv (Stock is 1250mv) the card running Heaven maxed out, never exceeded 50c underload and was completely silent. That is a good 30-35c improvement with the MK26 cooler over stock.

Maximum overclock does not improve any further with silent fans, but you can match the max overclock, again keeping silent fans your looking at approx 85c under load, so about 5c improvement over the stock fan at 100% which is hoover loud.

However this is the real sweet spot guys for 24/7 gaming:-

Core: 1100Mhz
RAM: 6000MHz
Voltage: 1300mv
Power: +50
Fans: Silent
Heaven 3.0: Tesselation Extreme, 16x/8x AA/AF at 2560x1440

Maximum load temperature was 62c and in SILENCE. :D :D
The stock cooler could do this but with two dis-advantages, you'd be pushing 85c area and the fans would be at 75-100%, so you'd be hotter and much louder.


In short this is the perfect gaming setup, yet you could push the OC easily to 1150 / 6400, but in our view why? Keep the card 110% safe and cool whilst still absolutely beasting everything.

The MK26 works superb, nothing is melting, VRM's, memory is all fine.

Soon we shall test EK Blocks for those who wish to go water as that will be the ultimate solution and a 24/7 gaming could be no doubt done easily with 1200/6400 speeds. :)
 
You guys should include the big Alpenfohn VRM heatsink and the tube of thermal glue for those of us that like to get obsessed with VRM temps and stuff :)

Or would that create extra issues with potential RMA's?
 
For such a massive reduction in noise without losing any performance it looks pretty good for the money.

What brand is the card itself? Or does it vary?
 
590g without fans, but it's not a problem.

I had a similar cooler which weighs 550g plus a couple of fans tied to it with minimal flex.


Just don't bounce the pc around and it'll be fine.

Given its power I wouldn't care about 4 slots - I ran a 3 slot 7970 for over a year. I expect this is an alternative to Crossfire/SLI for a lot of people rather than a restriction.
